Did the oil cooler for a coolant leak, still a small leak somewheres... No drips
Where else? I have a pressure tester coming, but i have no drips. I put about a cup of coolant in every 300miles or so. The system holds pressure, every time I open the cap it releases and the level cones up.
I do have a puff out the exhaust randomly, and smell some sometimes. There is no oil contamination.
Does the intake manifold have coolant passages? I have a cyl 6 and 8 misfire and P0455, so im going to remove the manifold to clean up the vario runners, replace the PCV and seal up if anything is cracked...
Where else is notorious for leaks?

I did the same thing and found more leaks...water ALWAYS finds the fastest way out...it ended up being a small damaged fin in my radiator so I replaced that and now have no issues with coolant leaks...I hope this helps somehow...

Oil cooler leak
Which gaskets did you replace?
Presumably the buffkin pipe/rings and the rubber oring on the long metal pipe that goes into the back of the oil cooler?
Well there is another larger gasket where the two sides of the oil cooler connect together. Did you change that one too?
I haven't seen anyone mention that one on here but that was the one that leaked on my car after I did the first three orings.

The little metal pipe (oe plastic) had orings on it, i replaced the one on the big coolant pipe and the "8" gasket on the cooler. I did not see any other gaskets.

Then it's possible that the gasket that seals the sides of the oilcooler itself are leaking. I would suppose that this is why others have replaced the whole oil cooler while replacing the orings.
