valvetrain geometry
 

i just measure for my pushrod length and i think the rocker geometry is pretty good.do ya'll think the pattern is good on the valve tip?
heres a vid of the geometry.

hope this is the right section.

It looks alright from here, but that doesnt mean ****.

take the rocker off, color the top of the valve with a marker, and put the rocker back on.
crank it over a few times, remove the rocker, and inspect the wear pattern

RE: valvetrain geometry
 

looks a little too far to the inside, aka pushrod too short, but you got to check the wear pattern with a marker like adder said

RE: valvetrain geometry
 

Yeah do what Adder said, that's how I did mine and it worked great. Also make sure you're using a solid lifter, if you're using one of the stock ones then it'll be inaccurate.

thx guys. i'll do the marker thing. i'm using hydrolic roller lifters. with it tightened down so as to compress the lifter about an 1/8" in.

You can't use a collapsed hydraulic lifter because when your engine is actually running the pushrod will be too long. You need to use a solid lifter so it acts like a hydraulic lifter pumped with oil when your engine is running. The solid lifter doesn't compress when checking the geometry thus giving you an accurate reading.

ok so i gotta buy 1 solid roller lifter and put it in and check it that way right? what a pain. lol.

if you want it to be right that's what you have to do. Or you can make a solid lifter out of one of your hydraulic ones: http://www.trickflow.com/articles/stroker_1/# Scroll down to where it says "Do It Yourself Checking Lifter"

RE: valvetrain geometry
 

the pattern your looking for will be a very narrow stripe right down the center of the valve tip. then your right on the money

cool thx onyx. thats what i'll do. thx again for the info guys.
