96 350 vortec no compression after head gasket replacement
Hi guys I am new here, I have a problem with my 350. I noticed a while back that I was leaking fluid so I took the truck off the road and started by replacing the water pump. Well I found out that wasn't the problem. I took a closer look and I found that I was leaking water from the head gasket. Well I replaced the gasket. I am not getting any compression in any of the cylinders. I am stuck I need to get it running. Please Help.

X3 on valve adjustment???
sometimes the hyd. lifters will get stuck up, when you adjust the valves down they will take overnight or longer to bleed down. I dont reccomend doing this, because theres always a chance of a valve hitting a piston, but you can crank it over for a while and they will start to bleed off and let the vavles go shut... but first we gotta know if you adjusted the valves right.

I agree with MDTahoe.....here is a tech explaining how to adjust valve lash from Mitchell
This is another way that I like to adjust these valves.
It May Sound Confusing, But When You Have Done it You Will See How
Easy It Works.
( Before I learned this New method I Watched as # 1 Intake Opened then closed and The Timing Mark came up, I Once got messed up this Old way on Astro van that had 3 Similar marks on Crankshaft.)
(1)
First Bring Cylinder #1 to T.D.C. By Turning Crankshaft Clockwise
While You watch Cylinder # 1's Companion Cylinder ( #6 ).
As #6 Exhaust Valve Closes, And # 6 Intake Valve Starts To open,
This Is #1 On T.D.C.
(2)
Adjust # 1 Intake And Exhaust Valves,
On this Application Tighten Adjusting Nut To Zero Lash Then Turn Nut 1 Additional Turn.
(3)
Since This Firing Order is 1, 8, 4, 3, 6, 5, 7, 2
Turn Crankshaft Again Until # 5 Cylinder Exhaust Closes and Intake Begins to Open.
This Will Bring # 8 To T.D.C.
(4)
Turn Crankshaft Again Until # 7 Cylinder Exhaust Closes and Intake Begins to Open.
This Will Bring # 4 To T.D.C.
(5)
Continue On Thru The Firing Order In Sequence Using The Companion Cylinders
Exhaust Valves Closing And the Intakes Opening.
Firing Order And (Companion Cylinders) Is As Follows
1(6) 8(5) 4(7) 3(2) 6(1) 5(8) 7(4) 2(3)

New here and I know this thread is old but it does relate to my situation. Pretty much did the same here but I really tightened down the bolts on the rockers and tried to start engine and got nothing. Did some research and realized I messed up. Had a guy help me who thought he knew what he was doing and just assumed it would be ok. So I have a truck with no compression and not sure where to start to fix. Did I bend the valves or anything else when I cranked the motor? Is this still just a valve adjustment and perhaps even a timing issue or did I do more damage and now need a valve job? Thanks for the help
