Even if there was little to no compression on that cylinder?

yup, still wont cause the spark plug to fire at the wrong time, or for the combustion to come through a stuck intake valve. Im not saying that you don't have bad rings, just that isn't whats causing your drivability problems. Did you have the popping through the TB before pulling the heads?

Yes. And it happens only under load in low RPM.

i still vote for a valve too tight

Okay, I'll throw that at him.

Thanks for your help man, I really appreciate it!

How come he put gasoline in the cylinder? Why didnt he do a compression check on all the cylinders?

You can easily check to see if a valve was sticking by using a dial indictor the rocker arm, turning the crank, then jotting down each lift exhaust/intake for each cylinder.

I don't know why he put gas in the cylinder. And he did do a compression check...

So I asked him if the bad rings will cause the popping through the intake/TB, and loss of power. he said yes, because the compression will pass through the rings/engine and find it's way out of the intake manifold...:waiting:

I will suggest this to him Ed, thanks!

does that NOT make sense?

Not at all! If the compression went past the rings it will pressurise the crankcase and most likely blow out the dipstick, or gaskets. It wont come back up through the intake manifold. If the valves are sealing correctly, im with Brad on thinking the cat's clogged. Did you ever get any readings with a vacuum gauge before tearing it down?

I think you mean Rob on the idea of the cat:wave:

K, i"m gonna remove that bitch if the new rings don't fix the problem
And I'll ask the mech about the vavuum gauge readings.

 

[THE lucky13]

i was talking about over on devilbrad, did someone here mention it too?

 

[03DakStampede]

yep i did. lol

 

[THE lucky13]

oh ok sorry

 

[03DakStampede]

ah im just bustin your balls lol not a big deal

I would remove the cat anyways since your going boosted that thing will get HOT!!

no worries! It takes a whole lot more than that to bother me

got the truck back today with $1,100 spent and the problem still exists. My cousin gave up. So the $1,100 was the labor for replacing the head gaskets the first time around. Then pulling the heads again to do the ring job. Ripped, I know. I'm over it. He had a professional head guy adjust the new valves and it still sputters under load (at low RPM) and pops through the TB. Also, he replaced the cam and crank sensor and removed the cat. Still no cigar. So I've taken it to a different mechanic (honest and has a good reputation) and explained everything to him. I don't care how much he charges me, just as long as she's running to her full potential! Anyway, just thought I'd let you guys know the bad news.
