You might just need a new seal.
Remove oil filter, disconnect water hoses, remove the nut, remove oil cooler.Its pretty simple.The gasket is just an o-ring seal, it will cost a couple of quid at most.
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?ThanksHi, I had the same problem on my 16v with the ABF it has a known fault of shaking the oil filter loose so check that and re tighten.
