Take a pic of the oil pump/front cover. I want to see if its OEM.

Hmm, this thread is interesting. I haven't heard a single thing bad about them until now.

This is a first for me too.

This is the First for me also. MAP took good care of my car. i spent like 3 grand there and till now the car is still in good running shape for 3 years. Sorry to hear about your built.

So you/they used a gasket on the pump cover?

I'm pretty darn sure you arent supposed to use a gasket on that cover at all.

[blackrosenova400]

On the small gear cover no. Im pretty sure hes talking about the oil pump front cover assembly.

But yes with a gasket there would be too much gear endplay. Also it could of had too much preload if those bolts on the small gear cover were too tight.

Here are the pics of the front of the cover. And the pic of the brown seal is the original seal. I replaced it yesterday with a black one that I had laying around (new) to see if it still leaked. That was before I took the pump off the block to find that it was messed up.
The DOH lettering on the front matches the other 2 old Mitsu pumps I have laying around.

Edit: Just spoke with Matt and it appears I took his post a bit out of context as we both agree it is very hard to determine what actually caused the failure here. Regardless, we have come to a resolution that is satisfactory to both parties. Hopefully Matt will be changing his initial post to reflect this shortly :)

Hmmm, in for MAP's side of the story...i like to hear both before i try to make a judgment.


Edit: ^ There we go.

Thanks for clearing things up Chris. If he did the assembly himself there is nothing you can do, that would be like asking Mitsu to warranty an aftermarket built engine.
