Does this sound like a head gasket?

After the supercharger install I noticed when I got on it heavy I would get oil spray out of the dipstick, and yes it was snug. No problem here I know Im getting some blowby past one of my pistons. I added catch cans with air filters on top to relieve some of the pressure, that pretty much cleared that problem up. Now on the drivers side I was checking the can and noticed a little bit of milkshake substance around the top of the catch can when I removed the filter. Now right away im thinking head gasket, however there is no milkshake residue anywhere else. Not in the bottom of the catch can none in the valve covers not on the dipstick and none in the oil when I drained it. So what gives. Do I have a blown head gasket or not. I did notice some white smoke out of the tail pipe but it cleared up after driving. As far as idle goes its fine. Its a little high but its always been that way since I got it out of the shop.:confused:

Sounds like condensation to me.

Pull the plugs. Take a look at what they look like.

This might help you.

There are a few symptoms of a blown head gasket. The first one is loss of coolant. Coolant can be lost from the leak in the gasket into the cylinder. From there it can go past the piston rings and into the crankcase or it can be forced out of the exhaust system by the action of the piston coming up on the exhaust stroke.
If the coolant enters the crankcase it mixes with engine oil. Of course oil and water don't mix very well but the presence of ethylene glycol (anti freeze) and the agitation caused by the crankshaft and other moving parts can whip the mixture of coolant and oil into a milkshake.

If the coolant is forced out of the exhaust system it is usually heated by the hot exhaust manifold and the rest of the exhaust system. This results in a sweet smelling steam emanating from the tailpipe. The steam is rather persistent, that is it will hover in the air and not dissipate like the normal steam that comes from the combustion process.

Testing an automobile engine for a blown head gasket is pretty straightforward. The first check is to see if there are combustion gasses getting into the cooling system. Take a sample of the coolant and go to the local radiator shop and request that they analyze the coolant for the presence of hydrocarbons. If they are present then it is most likely that you have a blown head gasket.

Another check is to look at the oil of a warmed up engine. The antifreeze in the oil will whip it up into a frothy brown mixture that looks like a milk shake. If it looks like chocolate mousse then you probably have a blown head gasket.

Another check is to fill the cooling system to the brim and remove the radiator cap. Do this when the engine is cool. Start the engine and race it. If there is a compression leak and the gasses are going into the cooling jacket then the gasses will displace the coolant. Since the cap is off the coolant will be pushed out of the radiator. You probably have a blown head gasket.
