Roller rocker madness....

Hey guys/gals

I have Probe 1.6 roller rockers that I've been "attempting" to adjust. I bring the #1 cylinder to TDC (I know it's TDC 1 and not 6 cause I feel a gust of air on the up stroke over #1 plug and can see the piston at the top) and adjust both rockers. I adjust by moving the push rod up and down until there is no play between rocker and rod (0 lash) and turn the poly lock 1/4 turn past 0, tighten set screw and move to next cylinder in firing order.

This is a fresh rebuild. I've only driven about 100 miles. I noticed I had a vaccuum leak around my intake, so I popped it off to reseal and adjust/check my rockers while I was at it. When I adjusted the rockers at TDC for each cylinder, I would check the other rockers that were not TDC and find some of them to be loose and have a small amount of gap between the rod and rocker. I also noticed that some of these rockers seemed "springy" when pressed downward onto the hydraulic lifters. I would go through each cylinder at TDC again and find them all to be perfectly adjusted while TDC. I know none of the rockers should be loose at any point, so what's the deal? All I can think of is air being trapped in the lifters somehow, but I'm not sure that makes sense.....

This is my first rebuild and I've never had hydraulic lifters or roller rockers before, so any help is appreciated!!

I've read anywhere from 1/4 past 0 to a full turn past 0, so I dunno.....

I actually tighten the poly lock about another 1/4 turn after I tighten the set screw as well, so I'm about 1/2. Something else I read......

Hey thanks 66....

I am using a flat tappet cam and am using the 15426378 sequence. I could try and go another 1/4 turn, but I'd be suprised if that made up the difference in the gap between rocker/rod that I have.

I don't let the poly lock rotate while tightening the set screw, but read somewhere that and added 1/4 turn on the poly lock after the set screw was tight would help keep it set and in place.....dunno if that's true or not.

I bought the short block, rods, rockers, cam and heads from the same vendor, so unless they messed up, I should be fine.

Yeah, I'm finding that this may be the best way to go. I didn't do it this way because it seems like such a mess. But, at least I could do it once and be done!!

Thanks for all the help....
