No filter cap leak on mine. Its from the housing. It's oem filter and all servicing has been done at a bmw dealer. Do you know if they change the o rings while changing oil filter at dealer? I was thinking of renewing the o rings if dealer doesn't replace them at every service.

Try trace where the oil is coming from. If its from the top cap - chance are its the O-ring.
If from the base, then youre screwed! |

Oil leak is fixed by replacing gasket. Afterleaving the shop, into 10 minutes of driving, I get an engine fault sign and loss of power. Took the car back to workshop and right now the car is getting diagnosed. Fml!

mine isn't leaking as much as yours but there's a seap coming from where the black filter meets the housing. (alo bit). I can see it clearly. I am getting mine changed in 3 weeks with a new oil filter. too long to wait?

Diagnosed completed. A small and thin hose feeding air into engine and a thick radiator hose above the fan had a leak thanks to wear and high running temperatures of this engine. Pretty disappointed but in a way I feel lucky that it occurred close to the workshop and whatever decided to give up on the car failed all in one bang, that way I don't need to worry about random things failing on the car after I bring it home. Total bill $400 incl. oil leak problem. Picking up the car tomorrow after extensive testing and hose replacements. Warning to all 335I owners, beware and replace all worn out looking hoses under bonnet because this engine runs very hot and this car is only on 75000 kms. Update will be added after tomorrow afternoon. Let's hope nothing else fails after pick up.

Not long but don't drive the car until then. Also check the coolant for any signs of dirt.

Tech said that gasket inside oil housing was worn out hence why it was leaking through the gap. Small fix. Said it was a minor leak and he'd seen much worst. Common problem with bmws he added not only 335s. A change necessary very 75 to 80k kms.
If you have to drive it, I suggest you get it looked within a week, not 3 weeks. Leak can get worst and do further new damages. |

Car is back to normal and running strong again. Brought her back home yesterday and took the piece with me that failed. I'll take a photo of it and post it up. Overall happy. Wanted to drive it today but it's raining. Standard Melbourne.

My oil filter housing has been leaking as well. I've installed Advan oil cooler with stock thermostat delete and there was oil leaking between the new backing plate and the oil filter housing itself. Wasn't too bad until one day the backing plate gave way because one of the bolts that secures it to the housing was stripped inside. Pulled over immediately and topped up with oil until I was able to seal it off securely. Also checked my coolant and found a lot of oil in there as well. Seems like the seal has 'eroded' between the block and the housing and the new backing plate and the housing. Going to replace the entire housing so the bolt screws in and I've got fresh seals as well. Labour will be expensive though.

Well, I've just hit 80k and as if right on queue - I noticed a few drops of oil around the filter.
I know an aftermarket filter was used so will check that first.. Just a <BUMP> as a reminder for everyone to check theirs! |

The oil gets so hot in these engines that over time the rubber type Orings go hard and no longer seal. The cost to repair is not to bad so dont worry to much, we can do this repair while you wait. |
