Hi,
The day after our holidays, one of the lifters start tapping very loudly. So
loudly that the mechanics at my brothers' garage feared the worst. I showed
them Mr. Bulley's sugestion (see below). Some laughed but others said that's
what they did to some older Chevy engines as well.
Before I followed the instructions we took the head covers of and cranked the
engine one turn at a time (special push button gismo hooked up directly to the
starter? that does not actually start the engine). We could clearly see which
lifter was not working properly. We kept cranking it for a few turns and it
seems that the lifter started the work better. At this point, we briefly
started the engine without the head covers on and the tapping sound was gone.
The mechanics think that by cranking the engine a turn at a time primed the
lifter/cylinder.
We put the head covers back on and I followed the instructions below (same
ratio's) and the engine has never sounded better. I wil do a compression test
next week.
I was using Castrol 5W50 synthetic oil which might have lead to this problem
(mechanics do not like it since it is to runny). Perhaps I should stay with
20W50. Any suggestions on this?
By the way when we took the head covers of there was very little oil in them is
this normal?
Thank you,
