Hey Everyone

I have been hearing through the grapevine about car owners (not necessarily Bonnevilles) who are or have or are having problems with plastic intake manifolds and how they eventually deterioate.

I have also heard that once this happens engine coolant begins to mix with the oil causing bearing rod damage.

Is any of this accurate? Now I have a 165HP Series I and I have been told that my intake manifold is not plastic therefore I don't have to worry.

But for my Series II friends, maybe this has been discussed maybe not, or maybe this is some GM urban legend?

Since my next car will be a mid to late 90'* SSEi Bonnie, I'd like to hear your input

Happy New Year!!!

True on the plastic intake issue and in your case keep an eye out for other gasket leaks. Not a hard fix with yours and mostly a more expensive fix on the plastic units.

Sweet...believe me, after my frost plug/block heater problems the last thing I need is to have problems with intake manifolds, and other expensive problems..

one less thing to worry about :?

By the way...

The SSEi models don't have a plastic intake; they have a supercharger there instead!

Once again the SC saves the day...I guess my mind has been made up, next car 92-99 Bonne SSEi....green...or red

They should have just stuck with the alloy manifolds in the first place as opposed to switching to plastic. Apparently the ally ones weigh 3.5 kg (about 9 pounds) and it made the car more fuel effiecient. I think over the long term you may spent more in gas then fixing a plastic manifold...but 3.5 kg?, c'mon...at least avoid the hassles when repair time comes around.
