Is My Car F'd?

They also have a huge problem with oil pumps that seize up after 300 miles or so. That could be what happened here.

Start over, use mostly Mitsu rebuild parts where possible, and make sure you check everything that had oil going through it, including the oil cooler. If you had a external one, throw it away, you can't clean them out enough not to trash a new motor.

Ok this time I am going to go with Mitsu pars mostly. My funds are limited tho. Just from reading this what should be replaced? Bearings is a given. And I need new rocker arms and possibly cams.

You are going to have to spend a lot of time cleaning oil passages too. Check the lifters too if the rocker arms are bad. Hopefully the rods are ok, check for any discoloration and also the wrist pins.

A must:
-Rod bearings
-Main bearings
-balance shaft bearings (either replace, plug, or what not)
-misc gaskets you'll need after tearing it apart
most likely:
-Oil pump assembly (not just the gears, probably need a front case, check spec)
-turbo
-crank will probably have to be machined
-rods possibly
-cams?
-hla's could just need a clean, oil squirters will need to be cleaned or replaced

Pretty much anything in the oiling system should be inspected for damage.
Mitsu parts we always use:
-Gaskets
-some bearings (if its a performance motor, it'll get kings or acl's)
-oil pump's
-sometimes water pumps
-misc other parts.
Mitsubishi has a very good quality control compared to most "aftermarket" parts companies, and it shows with the consistancy of the parts.

Yah this is old but I was doing a search and found a bunch of stuff about the oil pump failing. could that have cause all the chunks of metal? also how do i check if this is my prob?
thanks,

Make sure it spins freely, and take it apart. (if you haven't already) The CD you have should have the specs on it.

Old Thread Back from the dead...Today I took the engine out and took it all apart. Oil pump to me looked good, crank looks good, bearing are bad. The bearings looked as tho they shrunk. They come right out of where they sit. When I put them in they were tight. any thoughts as to what could have happend?

I would think it is ither a oil pump issue, or the bearing clearence is out of spec. I would have the crank checked out. Crank shaft supply, Wagamon Brothers (wags). King bearings would be a good idea along with a line hone with new mitsu main bolts. You might want to check your bearing specs with somthing other than plastic gauge, inside bore micrometer, and a normal micrometer work well.

I would be kind of leary about the crank. The rod bearings looked really bad. I agree that a line hone should be done as well as the crank polished. I would use King or ACL bearings when u reassemble it.
