I have a leak in B5 Passat 2000 with AJM TDI 1.9L engine. The oil seems to be leaking between the oil filter housing and the oil cooler (water cooled). I have marked the leak position in the image below (not from my car but similar enough looking part that I believe this is the same part): https://imgur.com/oQAErLx
The amount of oil leaking is not a problem for the engine itself so I have some time to figure out how to best proceed with the fix. However, I cannot just ignore the problem due the mess the oil makes.
Can you provide any pointers?
Is it possible to somehow tighten the seam (connection between the filter housing and the cooler)? Assuming, of course, that the seal just leaks and is not totally broken.
Do I need to remove all oil and water before doing any maintenance for this part?
Is this a common leak problem? Are there any preventive measures to avoid leaking from the same source again?
Does anybody have an exploded view of the construction of filter housing + cooler combination?
(Some additional text description to help finding this post in the future when you don't know the name of the things above: there seems to be leaking oil above the cube attached under the oil filter. The cube has two water connections.)
