Intake manifold question.

Over the weekend, I seem to have developed one good sized crack and a few smaller ones on my intake manifold.

I can get a manifold off of an 84 CJ-7 for a pretty decent price and was wondering if it would work on my 1990.
I know physically, it will fit because they're both 258's.

Did an 84 CJ-7 have the Carter BBD, or was it a "traditional" (non-computer controlled) carburetor?

The reason I ask is because my manifold has a red wire coming off of it from under the area where the carburetor bolts to the manifold, but the one off the CJ-7 does not appear to have this wire.

Re: Intake manifold question.

was 1990 carburated? if so yeah itll work

the red wire is the intake preheater, really just effects fuel mileage i think.

i have an 85 and my carter is computerized, so im assuming 84 would be also.

never let your jeep near crack [img]images/graemlins/wink.gif[/img]

Re: Intake manifold question.

Yeah, my 90 is carbureted.

I couldn't find that wire in my FSM electrical anywhere, so I wasn't sure if I really needed it or not.

Re: Intake manifold question.

84's were the stepper motor version of the carter bbd. And they did have the red wire for the intake heater you see also on your 1990. That wire should be there. If not, you can try to swap the heater off the bottom of your 1990's intake manifold. If you get the Fel-Pro intake gasket set, it comes with a new 0 ring and gasket for the preheater. I'm making the assumption that the pre-heater will swap between the two. You should have the pre-heater. It will help vaporize fuel during warmup.
