Should I even attempt to replace this oil pan?

My gut instinct tells me I have already spent too much time on this by starting this thread, but I would like some other opinions.

Lower engine brace has been missing since she owned the car, wishing I had found one to put on now.

The gf didn't see a median and partially drove over it, putting a huge hole in the oil pan. She then drove about a half mile to a mile and parked it.

The car is a 2003 sulev with just over 150k miles on it. I know, ticking time bomb.

How much internal engine damage would have been done driving a mile without oil pressure?

You should part it out and sell me your valve cover and dipstick tube.

Seriously though, are you referring to the plastic shield that is missing or the metal brace that covers the subframe?

Metal brace, but looking at the cross member it looks bent, so the metal brace probably would not have saved the oil pan.

Those are the only parts anyone will want off this. lol

I might snag the newer electric fan, bc stalk and headlights for mine.

it does have a bunch of new cooling system parts on it, metal disa valve flapper thing(don't think this will fit a regular 325i) sport seats (need some conditioning), sport wheel, etc.

Running the engine without oil for 1 mile should have very little impact on it. You would be VERY surprised what any engine can put up with.

I would be more worried about the front sub frame being bent.

In any event, it will take some work and being a SULEV car, if the fuel pump has not been replaced, I would not be spending a lot of $$$ on the car.

If the fuel tank has been replaced recently you could maybe get $1500-$1800 just for the fuel tank??

Uuuum, WOW! That is a large hole. I understand your complication. Replace the oil pan, put oil in it, only to find out the bearings are done for. I say do it.

I would let that go. Get another one if you really want to stick with an E46.

OP the oil pan costs about $200 used and $300 for labor. In all about what an e46 is worth.

Or get the GF something with more ground clearance like an SUV.

Are all e46 oil pans compatible with the sulev engines? Besides M motors.
I can get one for $50 and can replace it myself.

How about a new GF that pays more attention..

Looking for a lexus rx 330 or 350.

Any time you need to check parts compatibility, look up both part numbers on realoem.com and compare them.

01/2004 325Ci M56 oil pan:

Same part numbers: 11131432703

As to the lower crossmember, it's not all that hard to replace that, with an engine support.

Of course, you're into control arms, etc, in the 'while you're in there' department...

fwiw,

Alright, picked up an 04 X3 3.0 for her.

Who wants parts from the 325i? Valve cover and dipstick tube can go to Knight if you want them.

I guess I should start a part out thread in the classifieds.

Bet you could still get $250 or so for an original high mileage SULEV fuel tank with a working fuel pump. Problem is the size so someone would need to locally pick it up.

For someone that has a SULEV where the fuel pump died, they might by your tank to chance it for a few more years or to swap the tank to get the car running again to trade it in.

I think a new girlfriend might be cheaper and easier in the long run!

Sell car. Get new GF. Just kidding. That engine will take a lot of abuse/neglect prior to failing. Replace the pan and it will probably be fine from that standpoint. However, if the center cross frame is bent, may want to get an alignment check to see if the frame has been warped.

Just because it'll run without oil doesn't mean there isn't damage caused almost near instantly. Without oil pressure, most of the bearing journals will suffer damage immediately. They are hydrodynamic bearings and rely on oil being forced between the journal and rotating object to separate them.
