There is a very easy way to check the oil cooler for leaks.

Do this with the engine cool and be prepared to catch some coolant in a pan.

Remove the 2 coolant hoses from the oil cooler and attach them together using a 5/8 inch straight heater hose connector. You are bypassing the oil cooler temporarily. Wipe the oil cooler clean so you can clearly see any leaks develop.

Now run the engine and watch the oil cooler pipes (the ones you just removed the hoses from) carefully. If you begin to see oil seeping from the cooler pipes you've found your problem.

This might take a while to see so be patient and let the car run for at least 15 mins or more.

Don't worry about the cooler being disconnected while the car is running, but I do recommend reconnecting the cooler if you have to drive it even if you find it to be leaking.

If it is found to be leaking, you will need to replace the part and have your coolant flushed out properly to remove as much of the oil as possible from the system. Also change the engine oil at the same time, it is possible that coolant has gotten into the oil although it may not be obvious.

Good luck.

Oil in Water But no Water in Sump


Likely head gasket failure. Oil is higher pressure, and will often move into the coolant before coolant moves into the oil. As the breach gets worse, then cross-contamination will occur.

I have oil in the coolant of my 1999 VW Passat 1800 sport, engine code APT. Although on the face of things it looks to be a head gasket failure, I have been told that it may well be an oil cooler issue....


The oil cooler is almost definatly the problem

The reason for this is.

Your oil pressure is normaly anywhere between 2 and 5 Bar depending on engine temp and oil type, where your water pressure is never more than 1.2 bar. Thus the oil pushes into the cooling system due to the fact that it is of higher pressure.

In the event of a head gasket leaking it will push water into the oil not the other way round causing the oil to eventually go white.

These cars are known to have problems with their oil coolers from time to time.

Was the smoke white? if so it is probably your head gasket you can still save it if you want as long as the head isnt cracked as well then it probably just isn't worth fixing and from the sounds of it sorry to say but I cant be sure with out seeing it

Leaking head gasket


YES! Anti freeze can cause the pistons to sieze in the block & require major machining or wearing it to the point of needing more than just a gasket, you could end up needing an entire engine. The repairs need to be made immediately & the oil system will need to be flushed as part of the repair process if only the head gasket is replaced. good luck
