Recently had timing chain guides fixed. No sludge build up at all when i dropped oil pan and removed valve cover to set timing. Also inspected oil pickup tube and it appeared to be fine but I shot it with carb cleaner anyways. Didnt seem to bad. Not sure if its clogged but i doubt it because i have normal pressure at normal driving speed. Changed oil/filter (motorcraft).
Went with a thicker oil and lucas additive as I could tell there wasnt enough pressure on the tensioner and making the camshaft chain rattle.The thicker oil helped quiet it down for about a month or so but now its back. Also changed the sending unit but I can tell that this wasnt the issue because of the chain rattle.
Its only at warm idle. Drives fine otherwise and no other issues and no chain rattle heard or knocking heard as well (that I can tell anyways). No knocking heard either AT IDLE but I havent used a stethescope. Just the slight chain rattle. Its definitely the left side cam chain as i am very familiar with this sound. The rear is quiet. Oil level is good. Only happens at stop lights or at warm idle. Why could I be losing oil pressure at idle?
Any ideas what could be going on?
