Default Coolant mayo... clean oil!

Hello guys,

Had a heart attack yesterday as I was checking the coolant, there is mayonaise in there.. I checked some topics here and checked the oil stick, which is completely clean and the oil looks beautiful.

I went to the garage and they said 'New Engine' right away, they told me they could clean the radiators out (see if there is mayo in there) and the reservoir as well, this sets me back about a 1000$. This would not solve the problem and they said the best would be a new engine. Thing is, if it was a blown gasket, wouldn't the oil be full of mayo as well?

It has done about 85,000Miles.. It's a 2001 996 Carrera, 3.4L.

To the OP, normally a blown head gasket will allow oil into the coolant but not the other way since the relative pressures are higher in the lube system than in the coolant system. Cheers

oh us air cooled guys get mayonaise too , fairly common at different time of the year to get some out of the top of the oil tank or off the cap as the air becomes more humid.

Mayo in the oil tank on the air cooled cars is usually caused by condensation collecting and not getting the engine up to full operating temperatures or continually driving it short distances.

Mayo or foam or a brown milky discoloring on the water cooled cars is usually oil contaminating the coolant . Before replacing the motor I would give the system a flush and check the level of oil in the motor then run it parked for a while and check how quickly the oil returns.

The 997 has much easier quick disconnects on the front radiators than the 996, but this article will show you how you can disconnect the hoses and flush and or inspect the front radiators.

Drisump is correct it is more common to find oil in the coolant than coolant in the oil

Unfortunately, it is looking like it may be a blown head gasket but you can save yourself the $1000 and preform the shop inspection work yourself without any special tools.
