Blown head gasket or something else?
The last time I had my track car out it started smoking very badly (white smoke). I did a compression check and all cylinders are at 165 PSI except for number 2 which is at 90 PSI. Also when I pulled the plug on that cylinder it puked out coolant.
I just pulled the intake mainfold and I have coolant in the intake manifold valley too.
I'm getting ready to pull the suspect head right now but just wondering if there is anything else I should be checking?
How obvious will a blown head gasket be?
Thanks!!!

Yes, the car over heated during my electric water pump installation testing (dumb *** move on my part).

Some other members may chime in but my take is that you do have a blown gasket
If you have the $ it might be a good time for upgrades

Sammy is right.
Suspect a blown headgasket.
Do both banks or headgaskets.
Might as well because the intake manifold has to come off anyway.

How long did you run the motor? Antifreeze destroys bearings. You might want to drop the pan and replace the bearings while you are at it.
