Or at least it seemed liked it this morning!

It was a busy weekend! New heads (NOS), re sealed the plenum (again), new cat, new 3" exhaust, new plugs, and new sensor's. The only thing that wasn't changed was the TV cable. Still haven't received it, so ended up drilling a couple of holes to safety wire it.

It now drives like a totally different truck. Might have to keep it a little while longer

 

I hope those NOS heads don't bite you. What's up with your plenum that it repeatedly fails?

I'm glad that you're happier with your truck!

 

Me too on the heads. Checkbook only goes so far though.

The first time I did the plenum I used the Hughes kit, I used the gasket provded, but didn't use any RTV. This time I used the Fel-Pro gasket, and RTV. Hopefully, it's the last time I do that job! On the other hand I'm getting pretty good at it.

 

So your saying it is recommended to use rtv on the plenum gasket?

 

I read about using the permatex RTV in one of the numerous posts about plenum gaskets. Someone else was having an issue with their gasket blowing, and used the RTV without any more issues. I used the permatex black RTV, figured it can't hurt.

 

Ill have to keep an eye on mine then, i got the fel-pro kit and didnt use any rtv on the plenum gasket.

 

I used the Hughes supplied sorry piece of paper excuse for a gasket with NO RTV, as per the instruction's.

 

Stewie, I did the same thing. Followed the instructions to a T. Still blew out a couple of months later. We'll see what happens this time.

 

Maybe I'll have better luck.

 

I havnt seen the "Hughes supplied sorry piece of paper excuse for a gasket" myself but i always heard that you should not mix a gasket with RTV? either go one way or the other? anyone else know the answer.

i asked only cuz i forsee myself doin a plenum gasket fix and what to make sure i do it right the first time
