white foam

[billison]

Ok, I started pulling things in the engine bay to clean, degrease and paint everything, and I saw that around the thermostat is white crap, like foamy mold looking crap, I just put the intake on not that long ago, it does not have the thermostat in it or the gasket, I'M NOT DRIVING IT, IT WAS JUST TO MAKE SURE I COULD GET IT TO RUN...anyway what is it? and why? I'm gonna be pulling the valve covers to clean and paint same with the intake so if it's the head gasket I'm almost there....so, and it' getting a new radiator if that will help

Well since you don't have a gasket in the thermostat. It probally is leaking out and is having a chemical reaction. Just take it off clean it off and put a Thermostat and new gasket back on.

I'm gonna be pulling the intake for a cleaning and paint, I Just want to find out what it is, so I can fix what is needed.

Did you put straight water in the cooling system or did you use antifreeze. Aluminum will corrode, if it's just water it could be leaking around the thermostat housing and corroding the aluminum.

yeah I ran water cuz I've not really been driving it and I've been pulling the coolant hoses alot for differnt things, the main thing is I wanna know if it's a head gasket or not, cuz I don't wanna have to go back and pull all this stuff again, cuz I'm about to pull most of it for cleaning and painting...

car stored in warm garage? i hear it freezes pretty good up there....hate for ya to crack the block with pure water in it

 

[billison]

yeah warm, no freezing

Get some antifreeze in that water, just because your not driving it dosen't mean it's not corroding your cooling system. Your headgasket are probably fine.
