Thread: Coolant leak in number 2

I have a 02 Grand Prix GT with a 3800 Series II motor. i few weeks ago it overheated and both upper and lower intake gaskets were damaged so i bought the kit $79 and some change and put them both in. waited for the RTV to cure and fired it up started right up. the engine is shaky and there was steam coming out of the exhaust no CEL was on at first let it run 10-15 mins then it started flashing i am aware a flashing CEL is a misfire in one or more cylinders which i tested and is the number 2 cylinder that i know of right now............. after replacing the upper intake plenum gasket throttle body gasket all fuel injector gaskets.... ETC the kit basically came with all gaskets that are on the upper half of the engine excluding the head gaskets. what in HELL is causing the coolant to leak into number 2? this car gets me to and from work everyday so an intelligent answer from somebody that has had this exact problem before would be more helpful rather than guessing if you havent had the problem. Thank you..!

and a side note i have had more than one of these motors....... so i am quite familiar with them

97 Bonneville SE
99 Bonneville SE
02 Grandprix GT

My guess it could maybe be a blown head gasket.

I'm doing compression tests right now here is where I got

#1 105Lbs
#2 185Lbs highest pressure on the cylinde with coolant leaking in it
#3 150Lbs
#4 100Lbs

We haven't made it to #5 or #6 yet but will post the results after we're done with the test
