    Engine noise question

    Hey guys, I haven’t been driving my E500 as much this year and after having an issue starting it I replaced the battery. The car started and then I shut it off and it wouldn’t even crank over. I jacked the car up swapped the spare starter relay I had and the car started. After shutting it off it wouldn’t start again. So I put the original relay back in and the car started. However the same issue reoccured and I noticed that the engine was running weird . There is a vibrating noise and and a drop in idle. I have not done the plastic oiler tube swap and I have listened to videos of m119’s with bad oiler tubes and my issue seems different. The relay I used was from a w124 e420 which im not sure can be an issue as well.

    Thanks for the help.

    I'm scared for life by a Feb camshaft experience. Not indexed correctly, wrong diameter journals. Same with their sprockets.
    Jon might have some custom ones or call Tom Hanson. There has to be a better solution. ..

    What "relay" are you talking about? Part number?

    That is the combo relay for the turn signals / hazard flashers / windshield wiper. AFAIK it has no effect on the starter at all, and also should have no effect on engine operation.

    Hmmm weird maybe just a coincidence that the car would turn on when I would swap it out. And jack the car up on an angle. But still doesn’t explain the odd engine noise
