1.85 rocker question
I recently installed some Comp Cams 1.85 roller rockers and Patriot Gold spring in my Gto-'06 LS2.
I've adjusted the valvetrain according to comps instructions with the stock springs and found and repaired some clearence issues concerning the valve covers. Now I installed the PG springs(much higher rate), and now I have, what sounds like lifter noise/valve tap. Now there instructions say 1/2 turn past zero lash.
I found this:http://www.vincihiperformance.com/LS...TRUCTIONS.HTML
I know it's for Crane rockers but it's the same valvetrain and it says to adjust them 1 and 1/2 to 1 and 3/4s past zero lash.?
The clearence issue was with the oil baffle and some of the raised aluminum
at the ends of the baffle and under the coil mounting screw bores. The adjuster nuts were/are contacting the covers. If I turn them in more they might clear.
Question 1) How many turns past zero lash?
Quetion 2) Anybody else running this, or simular, set up have any issues. How did you fix it?
Thanks ThomLast edited by Damage Inc.; 03-16-2008 at 01:19 PM.

I installed SLP 1.8's on my LS1 and combined with the Comp 918 springs, it is a lttle noisier.
What does Comp recommend?

Their instr. say 1/2 turn past zero lash. Crane says 1 and 1/2 to 1 and 3/4 past zero lash. Thats a big difference. I know I can go more than the 1/2 turn with out bottoming out the lifter but how far is too far.?
Are the SLP adjustable?'06 M6 BOM: Pred, Kooks sig LT's, Magnaflow, Volant, Comp Cam 1.85, March UD. PB 12.92 @110.71 w/ 2.07 60' on street tires.
