Oil leak
« on: 02 June 2011, 11:46 »
Hi guys, I've suddenly got an oil leak on my abf.

I can see from underneath it's dripping off the filter housing, but from above the filter.

Had a good look and the filter isn't leaking, all sealed nicely.

Looks like it maybe from one of the joints in the housing.

Is this common? Any ideas where I should be looking?

Thanks

If it's from the oil cooler housing then it is likely that the pressure sender on it has popped a seal.

Easy fix and a couple of quid from an auto factors.

Is that on the top of the housing?

Just had a quick look and the three sensors on the top are not leaking, looks like onee of the metal-metal joints on the oil cooler housing.

Are there gasketed? How does it come apart?

Easy way to check if they are is to start the engine up, then get a mate to give it a bit of gas whilst you watch the top of the cooler housing. They will only leak when the system is pressurised.

P.S. make sure you have a good level of oil in the sump before you do.

Nice one, defiantly not leaking From the top.
Pretty sure its a joint leak.
Can't find the cooler in the Haynes manual, anyone got any info?

There is a gasket on the back of the cooler.
Also see if its mounted securely, i have seen one on an Audi where the nut had come loose.

Ok cool, think it seems to be coming out the back of the housing somewhere.

Anyone got any pics
