need help finding oil leak

[DSM's 4 life]

I am leaking oil somewhere in my oil cooler housing. Im thinking it could be the missing bolt. It seems to be just coated and only leaks under load not at idle.

here is a few high res pictures

Go to your local auto parts store and see if you can pick up a UV dye kit with a light and glasses and a bottle of oil dye. Put the dye into your crankcase, clean the area with all the leaking up real well with some brake cleaner and let it dry. Then start the car and stare at the area with your light and glasses and wait to see where it is seeping from.

fallenauthority is right with the dye idea. You might want to try putting some nylon tape on those AN lines first though. AN lines are good at making hairline leaks; and since that elbow was probably torqued to be aimed in that direction more-so than fully tightened, it may not be sufficiently torqued down as well.

Also, carb cleaner is a good tool for cleaning and drying an area to track an oil leak.

Then have someone hold the rpms at 2500rpms and sit there and watch for it. Bolt size for that hole is: M8 x 1.25 x 55mm

Thanks I think I will teflon tape the other fittings on there. There is no way it is leaking from the an fitting its on really tight and the leak is on the opposite side
