Oil filter canister leak

[mbro]

Hi all. My son's car, a 2007 GTI 2.0L Turbo has developed an oil leak. Purchased not that long ago, upon the first oil change it became obvious the previous person who changed the oil WAY over torqued the oil canister. I needed a 36MM socket to loosen it, and LOTS of oomph. It came loose, we changed the oil, and since then it has had an oil leak. I looked to see if it was the O ring around the canister, but its not - it appears to originate between the block and oil canister mount - the part the canister threads into. It being a Turbo car, there's a bunch of piping in the front of the engine, which is making this job substantially more difficult than I thought it was going to be. I drained the coolant, removed some of the piping, removed the oil cooler, removed the bolts that hold the oil canister, and its loose, but still won't come out. Wondering if anyone can direct me to any further details that I'm missing about doing this job. I have the new gaskets for the oil canister mount to block mating surface, and also for the oil cooler. With the engine in the car, its a bear to work on, but I'm not planning on removing the entire engine to replace 2 little seals. Grr. Any advice, help or input would be appreciated.

Ah yes, these things. Battled with one on a 40deg (Celcius!) day once.

I recall the top section of the intake manifold needs to come off.

Worth noting that the job has the potential to get a lot worse, as often where the seals seat, crumbles away, necessitating that the whole oil cooler module needs replacing.

This job just got monumentally bigger than I hoped... Thanks for the advice, I'll proceed with the manifold. Ugh!

The oil filter housing does need a 36mm socket to remove and when torqued correctly to 25Nm is difficult to get off again after a year of service. Nothing out of the ordinary here. It is common for cheap filter brands to have poor sealing rings, they often leak.

But as the OP says it is leaking higher up from the oil cooler.

There are a few DIY guides but given the PhotoBucket fiasco, I would recommend Pelican Parts Volkswagen Golf GTI Mk V Oil Cooler Replacement (2006-2009) - Pelican Parts DIY Maintenance Article

A brief status update. Along with injector seals (the O ring plus the collar and clip), intake manifold, and gaskets for the oil filter canister mount and oil cooler, I have this back together. The secret with the injectors is to situate them in the block, lube the O rings with vaseline, and then install the mainfold. No parts left over, and a massive feeling of satisfaction when I turned the key and it started right up. No leaks, so everything looks good! Super happy! It was substantially more effort than I thought!

Although I don't own a GTI, I read this thread with interest. After a difficult repair, there is enormous satisfaction when you get a good result. Thanks for reposting.
