that`* the answer, I really need to know. and also the ignition sensor (I hope that`* the right name?), does it fits too?
thank You!

Thank You!

Oh, now I have a question again about this subject.

Does the other GM 3.8 V6 crankshaft pulleys fit to Pontiac`*? Like for example: Olds Delta 88, Buick Le Sabre etc. `87-`91?

And the same question about the crank sensor too.

If the top kalf of the engine looks the same, it'll fit. Worst come to I have one.

Talking about log vs "snakes" manifold ? Through "C" 3800 (last used 1991), the balancer/pulley was a slip fit on a straight snout. "L" (most 1991 and later) uses a press fit on a tapered snout. Not interchangable.

Understand that (haven't seen one) that the '87 "3" and earlier 3.8 engines used a single ring crank sensor, later 3800s use dual ring sensors.

Thanks
