Has the car been updated to double row chain??????

arthur, this car was manufactured with a double row chain. I cant understand why I have this issue now. It seems there can be no peace.

I thought some '84s still had the single chain, but I guess not .

Anyway, I think your tensioner may not be holding oil pressure over-night

380sl timing chain tensioner adjustment?

That's where I would start too.
