89S,

I still got 350TBI engine and its still hooked up to the hoist. All I have to unbolt the trany and unhook the wiring harness from the trany.
I'm too far into this one now.

If I got shocked like that I'd probably start taking a baseball bat to it but that's how I deal with pain. For some reason pain instantly sets of my anger button. Not sure why :shrug:

Same


BTW 89S ,
Sounds like you need new wires :crazy:

Those bitches shouldn't be shocking you!
I remember when my old POS wires used to shock me :roflbow:

If you grab a plug wire on anything its going to shock you. I dont know where they came from but my dad has a completely plastic set of pliers we used to pull plug wires off.

The only way I can shut off my lawn mower is pulling off the plug, and it shocks the piss out of me every time.

Yeah, I was gonna suggest you lost a cam lobe cam. If you by chance got a rocker arm to tight, or your new springs are stronger which is very very lickely, it put more pressure on the old cam than it wanted and you chewed off a cam lobe. If so, all that fine metal is now running threw your motor oil and likley thru your bearings. Hate to suggest it, but if this happened all of a sudden, and not immediatly after your turne up as if you got the firing wrong, and you're positve the fireing order is right then the lobe it my first suggestion. Sorry dawg, hope I'm wrong.

You sure you don't have a pushrod that went through the rocker arm? The metal on the arm is paper thin and my Blazer has gone through two.

Not for nothing, but I usually go a 1/4 past the point where the ticking stops on rocker arm adjusments. As for the shock...You`ns make sure your pants are zipped up. When the horse comes out of the barn, and rests against a fender....makes a good ground. 5 and 7 are really easy to get mixed up.

I say no. He says he adjusted the valves several times. He'd have noticed that.

I think it is the lifter on cyl #3 intake. I will be diggin out my magnetic dial indicator this weekend and measuring the lift on it to see if it is in spec or wiped.

When I adjusted it Sunday, and put the preload 3/4 turn the book says, I saw the valve move, so that is telling me that my hydraulic lifter is not centering and must be bottomed out, that is also the same one that is pumping out a shitload of oil through the pushrod, like shooting right over the rocker arm and clearing the head, that aint right. The rest just normally bleed. They are my two clues so far.

Last night I looked at the motor running in the dark and I didn't see any sparks from the ignition or wires so I don't have a spark leak anywhere I can see. After work tonight I am going to pull that #3 wire off and I bet the truck runs the same. I think that is my dead cylinder.

I'll pick away at it and figure it out. I already vented and I am in the I don't give a **** mode now so I am good, lol. :crazy:

Those wires came pregreased in the boot with some of that diaelectric grease **** and I think that is why. You can see it in the pics, it's white stuff. But I looked in the dark last night and didn;t see anything arcing, just if you touch it, lol. :shitsweak:

agreed but why does he have to tear it down again?

I'd just yank it have the thing honed or bored whatever is needed, buy ya a cam kit from northern and/or a rebuild kit, master kit they call it, with oil pump gaskets and pistons, rings etc.

I'd quit messing with it and rebuild it and be done, either that or live with it's problems it has now and bad lifter or cam, buy one build it, minus the heads, then swap the top end over and drop in a new motor.
