87 Suburban, 5.7L TBI

I've been doing a lot of work on this Suburban (running gear) and decided to replace the valve stem seals while I was at it. All went well (I thought). Anyhow, I started it this morning and boy does it run rough. I checked the firing order and all is well with that. The only thing I can think of is I messed up on the valve lash. I'm following the shop manual instructions: putting it at TDC on #1 and adjusting the indicated I and E rockers, then moving to TDC on #6 and doing the same. I guess I could have messed up there. Anyhow, one question. The book says to take it to zero lash so I'm spinning the push rod and when it stops spinning I figure that's zero. Then the book indicates to tighten it "one full turn" so I am tightening each one 360 degrees or four 1/4 turns on a ratchet. I am making these babies too tight? Thanks.

i like to set the valves with it running ( yeah its messy , oil going everywhere ) but just back them off till they click , then tighten till they quit ticking and go a half turn after that seems to work for me any ways .

if you tighten till the pushrod won't spin you're WAY too tight.... you turn untill drag is JUST felt.... only a little drag.... then I like to go 3/4 turn but you can go 1 turn...

there are a lot of ways to adjust hydraulic lifters.

I like Beanes way.

others dont.

Everyone figures out what works for them.



if youre breaking in a cam, be sure to break it in correctly.

x's 2. Be carefule about running that thing with the valves to tight and possibly hanging open, doens't take long to burn a valve by doing that. The way I like to do it is by putting the cylinder you are doing at tdc. They with your pointer finger and your thumb pinch the pushrod and spin it back and forth. Kinda like ya would do to a chicks nipples, hopefully you are familiar with that. They slowly tighten the nut, while spinning the pushrod. When you just feel drag on the pushrod that is zero lash. Then turn the nut 3/4 to 1 turn more.

Thanks to all. I got it running this morning. I was just setting them WAY too tight. It purrs now. This thing has been up on blocks for months so my wife (and probably the neighbors) are elated. Thanks again.
