I noticed a small amount of coolant leaking from my 944S today. I am trying to figure out where it is leaking from. What would you say? Head gasket or the pipe above it that bolts onto the head that has some black rtv or something on it.(I didn't use rtv. It was some shop that it was taken too many years ago).

here are some pictures after I drove it for about ten minutes! Is there a coolant port right in that area on the head gasket?






Thanks

or it could be nothing more than a leaky coolant bleeder screw. ... oh wait is the bleeder near there on the 16v?

yeah, its in the same spot as the 8v

Curil-T sealant? It doesn't look like a liquid. Could be wrong though.

dillon410021

it is definitely coolant.

anyone?

anyone know there is a coolant part in that spot on the head?

Best way to find it is to get a pressure tester, like the one sold at Sears, and pump it up to 15psi or so. The leak will be as obvious as fox in a chicken coop. The silicon goo under the neck shouldn't be there -- what's up with that? Coolant travels well, so don't limit your search too close to that wet spot.

Pressure test, and check for leaks. from looking at your pic. your head gasket is failing.

Seeing as it is directly below the coolant neck for the head, I'm pretty sure there is coolant there. I agree with a pressure test of the coolant system. It will help you solve exactly where it's coming from.

Ok, I pressure tested the system. I put it at 16 psi and it stayed there and no leaks at where it was leaking before. I pulled the #1 spark plug and it was just as dirty as the others.

What do I do now?

Tom M'Guinn

I wonder if it is leaking only when the motor heats up and expands. Did you test it cold? Has the leak stopped completely now?

dillon410021

test was done with engine cold. I will do a hot test tomorrow.

Tom M'Guinn

Careful with that. The heat will create its own pressure to add to what you pump in...
