PCV hose broke

[JAL]

1990 3.1

A stalling/idling problem prompted me to replace the PCV valve. The hose, brittle as rock, broke in half unfortunately.

I wedged a scissors jack against the firewall to move the engine forward about 5 inches. (That's how I reached the valve in the first place). So I probably have enough arm room to work, butthe hose runs too deep into the engine for me to even feel the end of it.

So how do I replace the hose? My Dad thinks I might have to lift off the intake manifold to reach the hose, but I know nothing about cars.

(I just experienced the same type of problem. The hose broke off somewhere under the intake manifold and I suspect that the only way to replace the hose is to remove the intake manifold.

No, you don't have to remove the intake manifold, just the plenum. It attaches to the under side of it. Simple to do, just need to get a couple plenum gaskets which are very cheap.

all you need to do is remove the upper intake plenum, it's 9 bolts and a $14 gasket set (fel-pro ms94944). Tip the upper plenum up (so you don't have to remove the throttle body or the coolant hoses that go to it) and you'll see where the pcv hose attaches to the lower intake.

Wow! It's really nice to know that I don't have to remove the intake manifold. Thanks for the input!

no problem, glad I could help

You CAN get away without replacing the gaskets ...if you're CAREFUL!... I did...

And, while I was at it...I replaced the center section of the hose with a short piece of brake line that I bent to fit... At the ends, I used two short, HIGH quality hose pieces... I won't (hopefully) ever have to deal with a broken PCV hose again.

Just a suggestion.
