GM Plastic Intake Plenums

I wasn't sure where to post this.......

If you have a GM that stops and does not want to turn over at all then you may have a hydro locked motor.
Pull the plugs and try to turn over the engine.
If it shoots water out of a couple of spark plug holes then you need to check your intake plenum.
Remove the cover over the top of the engine.
If you have a plastic intake plenum, then there is a probability that the coolant passage has ruptured.
There is a coolant passage that runs around the throttle body.
This coolant passage ruptures and dumps coolant into the intake plenum.
The coolant then runs down and fills up a few cylinders locking up the engine.
The cheapest fix for this is to remove the intake plenum and use flush type pipe plugs to plug both sides of the plenum coolant passage....

My 1998 Bonneville was thrice doomed because of this useless part! First time I replaced the upper intake and the plastic gasket. Second time caused a piston rod to bend and ruined the engine. Third time I sold the car to a junkyard for $50 and bought another Bonneville, this time a 1995 SSEi. And it only had 104,000-miles!
