W114 engine ticking (continues)
The hunt for the ticking M130 engine continues.
i have isolated to the back top portion of the engine.
i have removed the 4 rockers for the last 2 cylinders (will remove the rest next week) and they almost look brand new to me. no signs of wear or abuse.
no signs of wear on the top metal portion of the valves either, same with the camshaft.
i did expect to see wear like some of the pictures posted by Luna but nothing so far. I'm puzzled, this hunt is taking way too long.
I will mention something else.
I did see wear on the valve cover towers, i did notice this before but i corrected it and I "believe" is from before. i made sure the cover is aligned properly and doesn't touch the camshaft.
Is it possible that when i tighten the cover bolts the towers lean and touch the camshaft causing the ticking?
can it be that simple?
it doesn't tick cold, only when it gets hot.
and at the end it is not the rockers or the camshaft what else can cause this ticking to check before i remove the head?
