Default 494 Pontiac

I had a slight ticking noise the other day in my 494 Pontiac
and since I have had all sorts of valve train issues
in the past I thought I better tear things apart
Engine has 3000 miles on it with a big lift .748 solid
roller cam and isky easy roller lifters. I was thinking
it may be a lifter going bad as I have driven it a lot
on the street lately. Still trying to determine if we
actually replaced the springs after redoing the cam
It looks like we may have taken the inners out and
tested the others. Glad I got to this before the valve
dropped. New springs should fix things but as always why?
Car did sit for a year and a half after my hip surgery so it
may have been compressed all that time and not liking it
If we did not replace the springs then the old ones saw
bad angles etc that may have not helped

Default Good save!

Wholly crap Bob! Glad you caught that before a valve dropped and made more than a "ticking" noise!

I should probably pull my 440cid and go through it soon... no issues but it's been 10 years so bearings should be checked and if all is well new gaskets and some fresh paint should make it happy for another 10!

Keep it Poncho powered!

Comp cams wants to know the
installed height of the valve. Going
to pull a spring in the front as it is easier to measure
I think they are worried about coil bind
