    OWNER - RENN GTS

    Hi all,

    Some of you might have already seen my comments in the for sale ad regarding the E500 which I just purchased, but I figured I'd start one of these threads here and give a little background on myself. I've spent the past few years in the Porsche world (personally and professionally), but have now happened upon my latest and most unexpected "project", a 1994 E500. The car has belonged to a friend of mine since about 2013, and I actually knew of the car and saw it when he originally took delivery of it from the previous owner in Illinois.

    While my newly acquired E500 may not have been done to everybody's satisfaction while under its previous owners possession, I have a different philosophy of what I think a car should be. When it came to my 964 project, every single part on the car was replaced with Porsche Original items, unless it was a factory upgrade such as the 993 Turbo brakes. The KW V3 suspension I justified as Singer uses the same setup on their vehicles. I intend on maintaining this same philosophy with my E500.

    Having spent my entire professional career thus far at the OEM level, I have a particular appreciation for the fit and finish of an "as delivered" product, and will spend the majority of my time bringing the car back to original condition. At the moment, I am trying to avoid a full re-spray as I did with my 964, and am considering having the bottom half of the car either re-shot in the original color, or color matched to the Black Pearl on the car. I know this is not correct to the car, but I feel that this might look best. What are everybody's opinions on this?

    Anyways, I am open to hearing everybody's advice. I realize that this car might have a bit of a spotty history with you lot, but I intend on spending time correcting what I can with it. The car isn't perfect, but I am hoping the knowledge gained here will point this project in the right direction.

    Cheers,

    Arya

    Re: OWNER - RENN GTS

    Here are a few pics of the car as it currently sits. I have removed the Brabus Monoblock II wheels in favor of a set of staggered OEM W210 E55 AMG Monoblock II wheels. Thanks to Captruff for setting me up with the wheels. Despite the chrome not being my #1 pick, I think it suits the car alright for the time being. I will most likely have the wheels refinished to silver, along with a brand new set of Michelin Pilot Sport 4 S tires installed once the car goes in to have the bumpers, sideskirts and moldings repainted.

    Also, the Brabus Monoblock II wheels are for sale. Please let me know if you are interested.

    Thanks!

    Car looks much better on Monoblock II. I would stay with orginal color.

    Hi Arya,

    Looks like you off to a good start. Meeting Captruff you already have a great guy to get advise from.
    The car already looks a lot better even if the Monoblocks are chrome.
    That was a nice set of wheels you got and will clean up real nice.

    I don't think I have ever seen pearl black car w/ matched bottoms. It would be different.

    This should give the owner the idea if he wants to go forward. I personally think he should keep it oem look

    Hi Terry. I agree, the car looks much better on the new wheels, despite them being chrome (typically a hard pass for me). Jeff was very helpful and seems to be a great resource to have moving forward. I have a feeling that the color matched bottom half will look much better when the wheels are refinished in silver.

    Re: OWNER - RENN GTS

    Yeah, MB made a mistake by producing the 199 and 040 cars with Alto Gray lowers. They look sooo much better in monochrome.

    Interestingly, MB seemed to figure this out for 009 Sapphire Black used on the E500 Limited, and offered on some late 124 chassis (circa 1995)... 009 only came with matching lowers.

    I hopping the AMG Monoblocks that we have all seen 1000xs are just temporary until you decide on what wheels you really want.

    So what if it is most popular rim choice on 124 there is a reason for that. Why he needs to change (besides chrome)? They are full face wheels and look good on 124 lines.

    Yes the Monoblocks look great on W124s and the 036 !

    I just like seeing something different for a change and based on what RENN GTS did with his 964 wheels and stance we just might get to.

    I've always maintained that 199 is one of the best colors to do matching cladding...

    Hey guys,

    Just a little update. Went to get a smog test today and failed. Car passed under load, but was considered a "gross polluter" at idle. Im thinking this could be the 02 sensor?

    Can you post the exact numbers from the test, both under load and at idle?

    It's possible an old/tired O2 sensor could be causing issues, but there are a number of other items which could also be the root cause. If you replace the O2 sensor (click here for info), you should re-set the LH adaptation (on a 1994 model, disconnecting the battery should work) and drive the car for a few days to let the fuel trim re-adapt. Ideally a digital scanner would be connected to view the current adaptation numbers, to see if anything is weird - adapted way rich or way lean - and then checked again after some miles are racked up with a new O2. Other items I'd look at are ignition system (mostly caps/rotors) and spark plugs, should only use F8DC4 non-resistor, with the gap increased to 1.0mm instead of the 0.8mm spec.

    That said - if the numbers are just slightly over limits, see if you can have the car tested hot. Drive the car 10-15 minutes at 50+ mph to have everything warm, then for the last 5 minutes before arriving, try to cruise at 4000rpm. Use 3rd or 2nd gear as needed but keep it around 4k for 5 minutes. This really heats up the cats and in many cases it should get through smog, unless something is really wrong. I figured out the 4k/5min trick a few years ago and have been very surprised how much difference it makes compared to just showing up with a warm engine. Best part is, it's free!

    I'll scan the sheet and post it up tomorrow. I actually tried your methodology to some degree. I took PCH from Laguna Beach to Corona Del Mar (Newport) to the smog station and made sure to heat up the engine by varying the revs in 2nd to 3rd gear. Specifically made sure to keep the cats hot for when I dropped the car off. He mentioned that the car FAILED by a pretty great margin on idle which leads me to believe that it could be the O2 sensor causing the car to run pig rich, which the girlfriend pointed out tonight without me even mentioning anything when I let her drive the car for her first time, idling at an intersection. The car has comprehensive documentation of the service history so I made sure to dig through all of it when I got back home in search of an O2 sensor replacement and was shocked that it had never been done before. The car is currently at 176K so Im assuming that its LONG overdue at this point. Matt at Leisting mentioned that it could be the spark plugs as well, so I think I will just hammer out both at the same time to be on the safe side.

    In regards to the proper spark plugs, is there a link you can send me to the specific plugs that I could purchase? As well as the O2 sensor. I did look at your thread but walked away from it still a little confused as to which specific part I should be ordering. Hoping to address these little issues asap, so I can move on to the more exciting stuff.

    Since you're a Porsche guy you are undoubtedly familiar with Pelican/Peach Parts. They have a good part lookup database, but AutohausAZ is a better deal than Pelican ----- and since they're AZ based, shipping to you in SoCal is very fast.

    Try these for the spark plugs / o2 sensor -

    http://www.autohausaz.com/pn/F8DC4 <-- Bosch non resistor type. Don't bother with the fancy Iridium stuff.
    http://www.autohausaz.com/pn/15058 <-- Bosch 4-wire 02 sensor -- 1993 model
    http://www.autohausaz.com/pn/13429 <-- Bosch 4-wire 02 sensor -- 1992 model

    In general though, GSXR's 02 sensor data is gold --- http://www.500eboard.com/forums/showthread.php?t=824

    Oh well, that statement applies to the US continent, the global picture is different, so that is alternative facts..

    I'm with Karl (post #21) - who has proven very tasteful wheel choices on the 036s he's had.

    Since you have Rotiforms on your 911, why not consider something from them?
    I would really like to see the VCE 03 on a 036.

If buying a bunch of OE parts from a discount dealer you can add them to your order and get them even cheaper. See post #2 in Gerry's thread with photos comparing OE to aftermarket. Main difference is country of manufacture, AFAICT.

    Also - as mentioned above, DO NOT use exotic plugs... no platinum, iridium, yttirum, or anything else. These fine-wire element plugs do not work well at all in the M119 engine, and they are all resistor plugs. The M119 is picky about good old-fashioned, fat-element, non-resistor plugs. Using the wider 1.0mm gap helps cure the intermittent hot-idle misfire (thanks to Klink & Jono for this tip, from elsewhere in the forum).


    JLAA posted links above for the O2 sensors. You can always buy OE/dealer but you'll pay a premium with no tangible benefit ($262 list, ~$200 discount). I would only buy aftermarket Bosch #13429 as the others have ridiculously long wire length. Amazon has it for $80 delivered:
    https://www.amazon.com/Bosch-13429-O...dp/B000BZG6LQ/

    Greg has a good point about the MAF, btw. That is difficult to diagnose without either swapping out for a known-good MAF, or using a digital scanner to view live airflow data.

    Thank you for the quick links. You are right, I didn't realize Pelican serviced Mercedes too. I don't buy from them too often as I source all of my parts directly from PCNA. I will keep my eyes peeled for the proper 1994 02 Sensor.

    Thank you for the kind words. I'm not opposed to a set of Rotiform wheels. I'm trying to keep the car as OEM+ as possible, but might have a look at a set of non MBZ wheels depending on whether or not I choose to refinish these in in Silver.

    Thanks for the heads up. I went ahead and read through your thread and your idle problem with "raw fuel" sounds pretty similar to mine. My car certainly does not idle rough or have an erratic behavior under hard acceleratin either...

    Awesome. Thank you for the tip. I will be ordering these today as a matter of fact, along with the 02 Sensor.

    It says that this sensor will not fit my car as mine is a 1994....is that correct?

    It fits just fine. Amazon's catalog is either wrong or overly conservative, depending on your opinion. Details are in the lengthy first post on the O2 sensor thread.

    Thanks for clearing that up. I'll be sure to refer to the thread moving forward. Just don't want to get stuck with the wrong part being a noob and all

    EDIT: I also went ahead and placed an order for the spark plugs through you on Ebay. Just wanted to give you a heads up

    Re: OWNER - RENN GTS

    No worries! Main thing is to avoid one of the sensors with the super-long wires. There's not adequate space in the driveshaft tunnel to safely tie it up, IMO anyway. The OE MB wire is even shorer than the 13429. There should be a date code stamped into the back of the plastic connector housing, many times it's illegible, but if not you may be able to determine the age of the existing sensor when it comes out - assuming it's OE. If aftermarket, you'll know it was changed at least once in the past.

    I am really curious to see the emission test numbers. If they are similar to Greg's before/after his MAF change - meaning, the idle numbers are grossly high - there's a chance something else is going on.

    Speaking of which, Greg, thank you for posting your results! Very useful info. I was not aware that an MAF could cause such extreme mixture errors only at idle, and otherwise work normally.

    Re: OWNER - RENN GTS

    That is very helpful - thanks for posting.

    For reference, Greg's "before" numbers, with bad MAF were:
    Idle: 586 HC, 6.29 CO <-- "incredibly filthy" was Klink's comment
    2500: 32 HC, 0.04 CO

    And, Greg's "after" numbers with new MAF were super clean - probably better than most:
    Idle: 22 HC, 0.02 CO
    2500: 27 HC, 0.03 CO

    Your numbers are:
    Idle: 269 HC, 0.17 CO (only 16 over the limit for HC)
    2500: 14 HC, 0.08 CO

    I'll go out on a limb and say your MAF is probably ok; mostly because both of your CO numbers are great, and idle HC isn't obnoxiously high. Your 2500rpm numbers are great. Normally I'd say to heat the cats up but it sounds like you did a good job of that already. I'd start by at least inspecting the spark plugs and eyeballing the caps/rotors. Don't replace the caps/rotors unless they are in really bad shape, that probably won't do squat for your emissions readings, but you can scrape the brass contacts clean if they are grungy. Plug insulators should appear light tan to off-white, not dark or black. If you can get the car on a lift and check out the O2 sensor that may help too, if you can tell if the sensor has been replaced, or read the date code.

    BTW - do you have access to a digital scanner? Either someone with a Chinese SDS (not expensive to buy, if you are a DIY'er) or a Snap-On MT2500 with MB kit? Or any scanner that will show you kg/hr airflow readings, O2 sensor voltage, LH adaptation values, etc.

    One last thought - check all the vacuum hoses, pipes, and fittings... and all the PCV hoses from the intake manifold to both valve covers. Any leaks in this area will cause unmetered air to enter the engine which could hose things up.

    I'll try and get the car up on a lift to have a look.

    I placed the order for the O2 sensor as well. Im hoping the new spark plugs and sensor do the trick. In regards to the digital scanner, I do not have access to one. I will try and see if anybody local to me has one that I can fiddle with. Maybe Captruff? I have to pay him a visit anyways for a few more goodies....

    Arya,

    This might sound like a dumb question. Has this smogger done a 500E before?

    Did he try to spin the tires on the roller? If he did it would fail.

    Just asking.

    Glen, if they had it in gear, it may idle at 500rpm. In P or N, it should be ~650rpm. Wonder if that would have any effect... not sure what the typical procedure is for CA emissions.

    Hi Terry,

    Im not sure. I took it to the Chevron test station in Corona Del Mar, off of PCH and Macarthur (across the street from Gulfstream). There were a few cool cars that came through there during the hour that I was there, so Im assuming that place sees some action from time to time.

    Why would the car fail if he tried to spin the tires on a roller?

    As far as I know, the idle test must be done with no load on the engine, that includes not having the car in gear during the test.

    036s can't be tested on the roller due to the ASR. I recommend watching the test being done. Some facilities have a lot of turnover and I've seen a share of folks that weren't quite competent. I recently failed one part of my test, (I believe idle) did nothing but open plug gaps and check/clean the 02 sensor and passed beautifully at a different station owned by the same facility. I suspected the tech at the time and still do.

    Arya,

    If it's not to far out of your way. It might be worth your time.

    I highly recommend this guy for smog testing. Don Kile, he works out of a Pennzoil Instant Lub in Orange, CA.

    The address is 4428 E. Chapman Ave, Orange, CA 92869. Phone 714-532-5227. (Cross street is Hewes)

    He has tested all of my Benzes for at least 20 years. My 500E at least 6 times.
    He knows what he is doing. He's honest and trustworthy.

    When he sees your car he will know who sent you and why.

    Good Luck
    Terry

    Terry,

    I will be sure to go here as soon as I get my O2 sensor and spark plugs installed. I grew up in Anaheim Hills, so I am familiar with that area.

    Whereabouts are you? Would be great to meet up sometime and check out your car

    I'm in Garden Grove but that will have to wait. My car is collecting dust in the garage. I have a broken accessory belt. That's not the problem I also want to install my new AEM fan clutch and fix a couple of leaks but the weather has been lousy lately.

    I haven't had much free time lately and partially a little lazy, crappy weather and a 31 day cruise to So America. My car has been left out of my activities for a few months.

    Anyway I plan on getting it all back together as soon as I can.

    I see you sometime this spring.

    Quick update. Car is going into the shop on Tuesday to replace O2 sensor and Spark Plugs (thanks gsxr). Once that is out of the way, I think bushings (rear subframe and front shock tower).

    Here is a pic as it currently sits. My other cars are starting to collect dust haha.
