Any Merc' Techs' out there please?
I've got a 1997 108D Vito, 47000 miles, (mine from new), oil changes never gone more than 5000, mostly done at 3000 ish, all molly coddled & driven nicely etc, & the top end has gone all rattley. Briefley, engine drives sweet when cold, & then starts rattling when warmed up, persevere & it starts popping back thro' the inlet manifold. However, to make life interesting, if I let it idle until warm, even until the fan cuts in, - no noise. only rattles when driven (ie. revved).
Lifters have been done, on the offchance, & made no change.
My question is, Does anybody know if the engines have any sort of valve/device to maintain / regulate / supply, the oil feed to the head for the lifters? & If so where have they hidden it?
Get as Techie as you like I was up to a short while ago a Self Employed Diesel mechanic, (got fed up with all the electrickery involved nowadays). Bought a Merc' cos' I didnt want it to go wrong ! Ha Ha.
Many thanks for any replies, & when I get the time (the joys of being employed alas), to get it sorted, i'l post the outcome just in case anyone else needs it.
