    Is it tightened all the way?

    You used teflon tape, right?

    Could be too tight in which case you cracked the OFH, cheers.

    You can't use thread tape, the sensors ground via the OFH. I had an issue with my sender leaking oil too, I got it as tight as I was comfortable with and squeezed a good size layer of RTV over the seams. Seems to have held pretty well for me.

    Apparently I should go ahead and remove my teflon tape then when I install my oil pressure sender, LOL. Thanks for the heads up, I did not know this. Saves me time down the road when im furious because my sensor isn't working. :)

    Rule of thumb, don't use tape, use liquid sealant (paste).

    Also, it will still ground with sealant on the threads.

    Tape will not squeeze out like liquid sealant though. If you leave a few threads uncovered you will be fine normally.

    If you know what your doing either way will work.

    Yes, all 2g's have the same OFH. Unless it happened to be 6bolt swapped. LOL

    Well the idea is that tape may become loose and find it's way into the tiny oiling hole in the turbo. Highly unlikely if I were to guess but more plausible than paste. I don't know about you but I've never had any kind of sealant squeeze into the direction of tightening. It always piles up on the outside of the connection. I also like paste over tape since I've seen this:
    Thread Paste Vs. Teflon Tape!

    Come to think of it, I never really liked the tape in the first place but that's just my opinion..

    Can also use a evo 3 OFH (which is sought as an upgrade because thhe filter is further from the exhaust causing the oild to draw less heat)

    You should really jack up your driver side, take the wheel off, wipe off the top of your OFH, and run your finger nail across the top (from driver to passenger side) to feel if it cracked before you take on this project.. and you also need to buy a OFH gasket from mitsubishi (dealer only part) they are $2.50. Good luck

    Same here, the tape is just a PITA. To the OP, like others said I would clean everything off the best you can and locate the source of the leak; you could end up taking on quite a project that you didn't need to. Purple power, simple green, or a similar degreaser with even a high pressure hose nozzle can make your life a lot easier.

    Can also spray the whole thing down with brake cleaner until its CLEAN, then lay down and watch the OFH and have someone start it, and try to pin point the leak, repeat until its found
