Foam in atifreeze Help
It is jsut as the title says, I have foaam in the antifreeze about the consitency of soda foam. I checked the usual stuff like the oil and it checked fine its nice and gold still looks new. tourqued intake bolts down checked the cap all seem to be in working order. My car has a crate motor 350 with a 650 holley and a gear drive car still has great oil pressure and the temp dosen't go above 170, oh by the way this isa summer car only so i bypassed the heater core any ideas.???? Mabye air in the radiator? I know that usually foam in the radiator means head gasket, but the coolant is still nice and green. Any suggestions would be great.

Would take alot of air in there to turn the anti freeze
foamy.
Jack the front of the car up pretty high, take the cap
off, and run it for awhile.
First, pull plugs and inspect for moisture.
Run Comp test with motor warmed up.
If done all of the above and still foamy, would suspect
head gasket

Re: Foam in atifreeze Help
Agree, it takes a lot of air in the system to make coolant foamy, like huge giant bubble impossible. Head gasket though, eh, do the guaranteed test first. Go to a place that has an exhaust analyzer and check for HCs (gas) in the coolant while the car is warmed up. It only takes a few minutes so they shouldn't charge much and it's a pretty accurate way to check.
