I haven't been driving my Mustang for a while because I knew it had some kind of cooling system problem. Coolant has been going somewhere, but nothing looks like it is leaking. I can drive around20-30 miles and the car will be overheating with at least a gallon low. I did some looking and testing on it today. Here is what I've found:

When I start the car and it hasn't warmed up yet there is a cloud of white smoke coming out of the right tailpipe. (each side goes straight back, no X or H pipe) When it warms up the cloud goes away.

I did a cranking pressure test on that side of the engine and all the cylenders were between 150 and 160.

All of the spark plugs were burning normal.

There was no oil in the coolant, and there was no coolant in the oil.

I'm guessing sincetherightside had a could of white that it might have been steam. I know it wasn't oil. Could I have a cracked head? Possibly a cracked block? I thought maybe a blown head gasket, but then the cranking pressure between the cylenders would be off andone of the spark plugs would have looked different.

Any one got any ideas?

YOU MAY HAVE A BLOWN HEAD GASKET ON THAT CYLINDER BANK...THEY make a test to confirm this known as a block check/test kit

Yeah it's a chemical that test for HC's in the coolant.

I'll look into that... thanks!

try unbolting the vally drain on that side, see if any coolant comes out...

I found one of these at Napa today but it was $50. For me that's a lot to spend on something I may only use one time. One of the guys there said if I ran my car with the radiator cap off I'd see bubbles in the coolant. I tried that got bubbles and lost some coolant.

I also decided to take one of the valve covers off since it was leaking so bad. It had plain ol' stock rocker arms. I was told it had roller rockers![:@]
