Well guys, guess it was bound to happen... Misfires intermittently in the mornings until warmed-up, cleared up for a while.... had to refill the coolant after 2wks....then one day she wouldn't stop misfiring.

Pulled Codes from Computer... P0302 - Misfire Cylinder#2.....

POOOOOFFF !! POOOOFFFF !!!! :eek:

that nice white cloud of blue'ish smoke rolls past the window...

SHUT IT DOWN !!!!! :mad:

Called Tow-Truck....... here's the result !!

Yup... Pic #3 shows the Dexcool sitting on top of the #2 Intake Valve
(actually stayed there overnite, meaning Valves are good )

All other Valves and LIM Gaskets seem to be ok.... looks like a Cracked Head on Cylinder#2

1 wk... should have her back up and running... $$$$$$$$$$$

Come to find out it wasn't a Cracked Head after all !!! Only a Blown Head Gasket ! :nx: :explode:

The beast is now up and running.. took lots of work... sorry i don't have any more pics..... was more worried about getting her running...

And is she ever quiet ........ runs really well.... especially after burning all the Dexcool from the Exhaust !! lol.... lots of steam & stink.... but all better now.

I've found the fel-pro kit for around $150.00 and i know a girl that works in the parts dept at local dealership who can get me the revised gm kit for $115.00..... is the fel-pro kit worth the extra $35.00

Well considering the revised kit from GM is on revison #3 Id go with the Felpro kit.

That sucks for sure about your car. At least you didnt completely destroy the engine. You should of parked it when you noticed the coolant going no where. Thats a dead giveaway of a LIM failure.
