a year ago my dads m43 developed a heavy lifter noise and after lots of struggling we somehow manged to get it quiet then...The noise is back now and is not going away!!!
so far:
At first we noticed lots of sludge and decided to run some flush and fresh oil. So far its been through 2 oil changes.
We bought a new set of 8 lifters twice, replacement camshaft, replacement cam followers but the problem persists.
Seems the first lifter (exhaust side) and first lifter (intake side) keeps on collapsing. At this point i'm sure all the lifters i put in these two holes cant be faulty and that it must be oil delivery related.
Can anyone shed some light on this matter?
