Hi all,

I've noticed an oil leak while changing the charge pipe of my car (M2 N55 25k KM).
Only other mod I have is a downpipe.

Looks like it's between the engine and gearbox.
Should I take it to the dealer?

[DanG]

I would. You are still under warranty so why not?

[gmhl10]

It could be leaking from the front and the wind is pushing it towards the back when the car is moving. Oil filter housing gasket??? - it's fairly common leak on N55

Nice catch OP,

Found the same thing at 17k miles....oil pan gasket.

Luckily its under warranty.....if not under warranty...and you can't stomache the job....its roughly 1400 from quotes I've seen.

Its a bit intensive...need to drop the subframe to access it.

thnx guys. The dealer shouldn't whine about the catted downpipe, right?

Noooo. Has nothing to do with that oil leak.

But nothing is 100%. Some guy at some dealer somewhere who is having a rough day could make an issue over it.

Think you'll be fine

From your pic it looks like the oil pan gasket to me. I once had a modified SRT-4 that had an oil pan gasket leak. I took it in for service and first guy gave me grief over the fact that it had an aftermarket exhaust on it. I asked him how that could cause an oil pan gasket to leak? He was fine after I had him actually think about it. I think you should be fine.

Definitely the OPG. My N55 just started at 80,000. How many miles on your car?

Whoops - didn't read OP's country

I've read that it can be a common thing on an N55. If it does happen I would expect it to be higher mileage like yours. I think the OP mentioned he was at 25K KM so that's like 15K miles.

Wow, a common, labor-intensive $1400 issue on a BMW with less than 100K on the clock? Noooooo....

[squixs]

Yup 25k Kms , so ~15k Miles. I wouldn’t found out if it wasn’t for the charge pipe swap, since the reinforcement plate blocks the view.

Also, I had a oil service around 1000 KMs ago, maybe they overfilled it or something.

Unfortunately It's very common. If I do our 335i it'll be the third OPG for me

2005 e46 330ci @ 70K
2011 e90 328i @96K.
I also have a 16' S55 M3 but might trade it in on a M2 Comp before that one leaks!

It's a doable DIY, but dropping subframes can be an extreme patience tester.

First of all, he's in Germany, so MW act doesn't apply..

And yes, they can make a case that the downpipe overtaxed the motor, causing the oil pan to leak and politely tell him to go kick rocks because he tampered with an emission control device..

It might not be true but that's how the game goes when you mod a stock vehicle and expect the manufacture foot the bill for a repair.

Don't believe me? Just wait and hear what they say..

We need a realistic list around here somewhere. Like the water pump thing, that happens around 80K miles too, right?

[CryptoM2]

Same issue on my car at 9k miles. Was hoping it was just a one off. Guess not unfortunately.

Also oil pan gasket?

No drips on the garage floor? Are they being caught by something under the car so it doesn't drip on the floor?

[dasblack]

Anyway of checking the pan yourself? I'm bringing my car in for my last service before my warranty expires this Friday.

Thanks
