-AN10 Oil Return Lines - Evo / Colt - MR258477

My car uses a MR258477 oil return gasket which I believe is common place on Mitsubishi turbos.
Hence i believe i can retrofit evo or vr4 oil returns.








What a bitch it was, wrong bolts were supplied. Oil drain attachment flange had to be cut and refaced. The turbo vband didn't provide enough clearnce.

-AN10, new gasket and loctite no3

How it should have been designed, had to go get new proper bolts!















I believe this was included in my kit:
2 x AN-10 to M16 x 1.5 Metric Straight Adapter
1 x AN-10 X 90deg. Push lok barbed hose fitting
1 x AN-10 X Straight. Push lok barbed hose fitting
2 x oil drain adapters
2 x MR258477
2 x M6x1mm (useless! not enough clearance to use them, had to go get allen key bolts)

<Can u see i temporary looped it>
AN fittings are to large and interfered with each other

Back in 2010 I did a cork gasket install -
done a standard oil change...going to dyno soon wanna get car ready...
notice a while ago the gasket on the oil return line to the sump was leaking...
made a new gasket out of cork, hope it holds
added an oil temp sensor i got from a friend...will wire it up another day, but it is mounted...used teflon tape to seal
used the evo oil filter it is not as long, hence more clearance Z436
