When their was oil in the lifters, all I had to do was put my finger in that "cup" and oil would come right out the hole. Their was really no pressure at all.
You need new lifters

As far as the gasket... That kind of sucks... Because they were figuring my compression ratio to be 10:1, but then they used the gasket that came with the Fel-Pro kit, which was thicker then they anticipated... so they lowered to compression ratio to be about 9:9 or so. What exactly the thickness of the gaskets was now, I don't recall?? Sorry.
The fact that EVERY lifter rattles... I think tells me it's the push rod length. I think?
Can I just make square shims from aluminum cans? I don't know what else would be easy to cut to size. I guess I can mill around a hardware store for a while.
Also I can't really check preload without new lifters anyhow, right? Don't they need to be pumped up to check the preload?
Well... That's the problem, the plunger is already all the way down. There is no pressure.

change the cam too too many flat tappet cams going flat these daysMy engine has about 250mi. There is a pretty loud tick on the top end at the #8 cylinder. I have a feeling that the cam is wiped. The exhaust manifold seems fine.
Since this is a pretty fresh engine, my money situation is now nothing, so this sucks. I am thinking about just getting a couple of new lifters and placing them in for the #8 cylinder, and see if that fixes it first. IF it doesn't, my guess is that it would be the cam. Now... If it is the cam I am kind of afraid of metal floating in my oil, but I don't know? Since there is so few miles on it, do you think I can get away with just installing the cam, and new lifters?
I know I SHOULD tear the whole thing apart and check everything. As I say, I'm a poor boy right now.
Am I on the right track? Is this what you would advise doing? I did have a shop quote me $1500.00 to tear it apart, and clean it out and place it together again. He figured since the heavy work is done (like the heads) 250mi ago, that $1500.00 would be about what they would charge. I don't have the room to do the complete engine myself.
I have options here... but what would you do? What could I get away with?
Thanks much!
forgot shorter pushrodschange the cam too too many flat tappet cams going flat these days
use comp break in oil or additive new oil sucks now days used to be only chevy cams went flat....
I think you just have a bad lifter in the bunch.
One sound=One part
I can make dry lifters do it or a lifter that has bleed down......they have to have oil in the to stay "pumped up" if you had a bad "collapsed" lifter....it will not hold the oil pressure in the lifter and will not let it pump up and maintain pressure.
