No boost + lifters
So I notice when my car turns off my lifters all leak down. I suspect they might not ever even get all the way pumped up.
That would defiantly explain why i cant build boost and my car is so damn slow.
And I've noticed my oil pressure is lower than normal too..
What are the odds of having bad lifters? they are the older Comp "R" style.

so its normal to not really be able to see which ones are up and down when the car is off? I seem to remember being able to see that when it was stock.

just for the record my car stock internals ls1 in the tucson 114* heat less than 20 psi at idle some times. my lifters still keep the valve open.

hmmmmmmm. cant belive the whole lifter batch would be bad. I have seen a lifter go bad on a high mile engine. once I saw i think like three on the same engine. So do all the valves do this ?
if not how many.

I've noticed a few will stay down, have not really done a lot of research on it yet.
It just occurred to me the other day that could be my whole problem not being able to build boost.
