Re: lifter question/help

this is just a thought here, but can it be that the cam bearings are not installed correclty? causing your lifters getting not enough oil? do the lifters push out oil when you run the engine? shoudl take 30-40 sec for them to squirt oil

I didn't assmble the short block but I can only assume that the engine builder knows his stuff. I'm going to pull the valve covers off again this week and recheck the valve lash. I guess I can start the motor with the covers off and watch the oil flow.

Re: lifter question/help

i started the engine tonight with the valve covers off and each rocker had equal and plenty of oil flowing through them. Immediately after I shut the engine off the lifters were pumped up rock solid.

Re: lifter question/help

My :2cents: here is you've set the lifters wrong. A surefire way is to pull the rocker covers and watch #4. When the exhaust just closes and intake just opens, AKA overlap, adjust #1.

Then, in order:

watch 3 adjust 6
watch 2 adjust 5
watch 1 adjust 4
watch 6 adjust 3
watch 5 adjust 2

This requires just shy 2 turns of the crank but rockers -will- be adjusted correctly.

I have standard Comp lifters with the later pedastal mount rockers and custom length pushrods. No issues but a PITA determining correct pushrod length to start with. I can tell on start-up that some have leaked down. In general I don't consider that a problem but that's just my opinion.
