Cracked Intake Plenum...Options??
Hey everyone
Sorry to be posting so much. I’m new to the trucks so I have a lot of questions and this truck is kind of a pain in the butt.
While working to to get the drivers side exhaust manifold off so I could Heli oil the flange threads, I noticed the very front bolt boss on the upper intake plenum is cracked and looks separated from the rest of the plenum. I sprayed carb cleaner on the crack while it was running and it’s not sucking air.
My problem is that I have a rather substantial valve cover gasket leak on the passenger side which would require removal of the plenum.
And although it’s not leaking now, I’m not confident it will seal back up with a new gasket.
What do you all suggest short of having a fab shop weld it up.
JB Weld?
RTV the crap out of it when I put it back together?
i got the truck as to be a garbage/farm truck for $500 so I’m not trying to spend a ton on this thing.

Which engine?
With a new gasket, it might still seal with one missing bolt as long as the crack is only in the tab.
You could pick up a replacement from a junkyard as well, that's probably the safest way to go.

i didn’t even think of that! Checked my local pick n pulls websit and they show an intake for 38.99 plus 4.99 core. Seems kinda steep but certainly a better option!

They just want that scrap tonnage.

If I had to take the core back out to where I go, they would pocket my $4.99 because it wouldn't be worth the trip. They probably count on that more than getting a few lbs of metal back. Those guys don't leave a lot of meat on the bone with those cars. LQK salvage (a public company) has several pick and pull places in Houston and they are in other cities and states. Their revenue last year was 2.47 Billion. I'm not calling them a junk yard anymore

I probably will not take my old intake Plenum back when I pick up a new one.
but I did find that the Plenum was leaking severely. Not from the crack. The bonehead that had this truck before me decided to not use the rear two bolts to the Plenum. It was sucking tons of air through the back. After I replaced all the bolts, the idle settled down and everything is good.
