Today i "tired" to lash my valves and ran into some problems...i know the prcedure and i beleive i executed it correctly..
while the engine running loosen the adjusting nut (in my case an ARP poly lock) untill it taps then tighten till it stops then go another 1/4 turn..i did this to the entire driver side and then turned the motor off...i tired to move the rockers and sure as **** they were loose...i went and did the other side and wehn i was done they werent as bad.. WTF is going on...

BTW...Stock LT1 cam..LT4 heads have .525 max lift springs installed

 

Sounds like you did it right. I'd went an additional 5/8 of a turn instead of 1/4 turn.
Some of the rockers will be loose after eng is shut off since the hyd lifters bleed down.
Some of the rockers will stay tight if their respective valve is open.
That's normal.

 

lifters bleed down and makes rockers loose, nothing to worry about

 

DOUBLE ..youd think id remember that

heres anotehr one for you 2...whats the advantages/disadvantages to preloading the lifters 1/2 turn to a 1/4 turn?

 

i read that some guys use a full turn after lash...
right now my valves are set to a /4 turn but there still makin some noise not really a clap more lile a little tickx16

 

im not sure about the roller blocks, but my 85 lg4 liked 1/2 turn after no noise.

 

on hyd lifters on my car i set them with the motor off.
it works good for me coz the high pressure oil pump gets oil all over.
but i also set them running some times.

 

i use "more than 1/2 turn" after zero lash. never had any problems and i'm not all that precise with how far past 1/2 turn i go, but never exceed 3/4 turn.

 

thanks guys..ill set them another 1/4 turn today and see how much that helps..
