I should have said something yesterday, I knew you pulling on the breather elbow, not the pcv . Sorry.

 

It's cool zman, you've been awfully helpful in the past!

 

And hopefully in the future.

 

hmm So those 426 pluggs a little cooler than whats stock?

I was looking for plugs today , I had it wrote down is Autolight Copper 3923 cooler than stock?

 

Its 436 and they are just stock heavy duty truck plugs. The 3923's are cooler than stock. No need to use them if you have fixed your plenum, cat,o2's and checked for the death flash. In which case you'll want a tuner, and depending on what you purchase for a tuner, you may want to use the 3923's. I suggest you do some reading around here on DF.

 

Hmm wish I had read that this morning. I thought I done good .........? I have fixed my plenum, cat,o2's
, I tell ya i had to go to 5 parts stores to find those 3923's. Napa only one had em. 1.77 cents each !! just put em in this am.
My tuner is a SCT . Should I have left the dang plat in it?
Speaking of pcv vavle that little booger in my truck was sounding like a rattle snake!

 

Walmart also has 3923 Autolite's

 

Ahh man , after changing those plugs, Got out my SCT programmer and it dont work anymore :0. OMG
Dont remember if I have the factory tune or the 89 tune on my truck currently,
Only reason I changed those plugs was to use the 91 tune, Damn.
The sellect button is unresponsive . One year and 28 days old, used one time.

 

Did you buy it from Hemifever?


I just noticed a ? you asked. You fixed the plenum, but used the original steel plate?

 

Go get dealer PCV. I got one from O,O,O,O'Reillys and also thought had a rattler in the dash. Tracked down the racket to oversized PCV. Didn't notice it until after relpacing valve cover gaskets. Side note: I reused stock steel pan on plenum repair.
afraid it might have blown again, did the vacuum gauge in breather hose with PCV hose blocked off. Went for 25 seconds and got positive flow of 2-3 lbs, no vacuum.
