OMP oil leak. Gasket or Pump?
I am not too familiar with OMP's. I have a decent oil leak from the from main seal and also what seams like the OMP. The leak seems to start when the car is worked (track days).
Before I hit the classfields, what is the common culprit for a leak from the OMP? Is it just the gasket or the whole pump? New pumps are stupid expensive. My car has about 50K miles btw.
Also, any tricks on taking off the main pulley nut to replace the front main seal lol? I hear those can be on there tight.

The front bolt is loctited from the factory, so even though it was supposed to be installed with around 100ftlb, it usually takes closer to 700-1000ftlb to remove it. There are 2 methods I have used:
1) strongest impact gun you can find...I use an Ingersoll Rand Titanium 1/2" 1000ftlb rated gun. About half the time or more it will not take the bolt off. In that case I use an oxyacetylene torch to heat the head of the bolt. This will usually melt the loctite and let you have a better shot at removing it with the regular impact gun.
2) If the "little" impact gun won't take it off then I get out the big boy...a 24" long, 1" drive shaft, 1800ftlb impact driver normally used to work on heavy equipment. That gun ALWAYS takes the the bolt out.
The latter is not an option with the engine in the car due to room.

That 'O' ring would be my first suspect. I've never had a leak there, but on the OMPs I've removed the ring has always been flattened pretty badly. The only other place is the copper crush washers, but in my experience if they haven't been disturbed they don't leak.
On other thought, the lines for the OMP run up just above the front hub. I could see a leak from that area following front cover and/or OMP lines down and making it appear the source is the OMP...when it isn't. Depending on how badly it's leaking, you could clean it up really well before the next event and narrow it down by looking for the source afterward.
