Can the oil cooler crack and leak only when car is running?

I just bought my first dsm a few days ago for 2500, talon tsi with 103k. Needed cleaned real good on the inside and some here and there parts. Ill post up some pics when I'm finished.

Back to my question, I drove it all the way from the person i bought it from to my house which is a good 200 plus miles away with no problems, all the belts were just changed and fresh oil put in. Last night I was driving it and my oil light came on and I lost all oil pressure. I shut the car right down to find a trail of oil behind my car. Got underneath and the oil filter came loose. Tightened it back up and put new oil in and drove it home. This morning i was taking it to a buddys garage to determine why it did that and the same thing happened. I couldnt diagnose the problem on the side of the road with no tools so I put new oil in it and drove it home.

With fresh oil in it and only when the car is running oil LOOKS to be leaking out of the oil cooler. Is it common for the oil cooler to crack and leak? Or could it just look like its leaking if the 23mm bolt that holds the oil filter is loose?

Thanks and BTW if anyone could give me a part number for the coolant hose that runs from the oil cooler to right next to the radiator cap it would save me alot of time.

i had the same thing happen. it dumped all my oil out on the road. i replaced the whole thing with the new housing and the oil cooler

If someone torques that huge bolt too tight it will crack the oil cooler pretty much instantly. Check your coolant for oil, and oil for coolant, too.

So just drain both the coolant and oil and check?

Its leaking out of the side pictured here. I assumed this was the problem but I cant find this oil cooler anywhere.

Junk yard is your best bet. Any from a 6 or 7 bolt will work. It could just be the seal between the cooler and the housing.

i went to the external oil cooler. so far so good. i like not having to worry about that interchange of oil and coolant

If you do buy a new one go to a air cooler setup.

Well if its just the seal where could I find one? Ive been searching oem websites for it and no luck. If I would go the route with an external oil cooler would it be hard to install? and would I just bypass the stock oil cooler?

It would be difficult to go to an air cooled setup. 2 options: sandwich adaptor or evo oil filter housing (90 dsm housing if you have a 6-bolt). Sandwich adaptors rely on having a threaded stub sticking out of the housing, and wouldn't be easy to replace the cooler. The stock threaded piece may work, I really don't know. Getting a different housing and all the plumbing would be easier, but you have to take off all the accessory belts, crank pulley, driver's side engine mount, and the timing covers to even remove the housing.

After I had some time to actually get dirty I found the oil filter bolt to be a little loose and the o ring between the oil filter housing and the oil cooler to be cracked away and completely missing a chunk.
