did compression check. perfect... so not suspecting any cracks/head gasket problems.
if i rev the motor small bubbles start to appear out of the neck on the radiator.
next thing i know it's foamy.
this is pushing water out of my radiator and flooding my overflow container. THEN, when the motor cools down, i'm low on water because of what was forced out and THEN i overheat.

what could be causing this? i'm stumped!
i may try a leakdown anyway?

 

yes try a leakdown to be sure

 

assuming the leakdown doesn't show anything.. THEN WHAT??

is it POSSIBLE the leak down will show something the compression check DIDN'T?

 

bump?

 

A compression test by cranking the engine over is much too fast to reveal a small leak into the water jacket. Think about it for a second. At high combustion pressures when the engine is running you are only getting small bubbles. At much lower pressures when you are only cranking the starter and no combustion is happening, you might not get anything at all. Bubbles = combustion gas coming from somewhere, so I hope it's a headgasket because everything else is worse.

 

mother fvcking WERD. i'm praying it's a head gasket 'cause if it's a sleeve, i don't have the $$ to have it redone. if it's a water jacket .. well... we all know what that means.


anyway, i can TELL if it ONLY the headgasket??? i've been suspecting head gasket problems for some time now.
