E92 335 oil filter gasket leaking.

Zysos617 · 10-24-2012, 02:57 PM

i took my car to dealer last week and they told me that my oil filter gasket is leaking, quote 650 to fix. i took a look and saw only little oil splatter. and last time i changed my oil was around 4000km ago and my on-dash computer never showed any oil loss.(not even one tick/bar, i check it all the time, every time it is at max.). should i do it or hold off till at least computer tells me that there is oil comsuption... thanks alot.

since i dont have any visible oil cosumption. oil filter gasket leaking is not causing any dmgs. am i correct?. thanks for any suggestions.

also i have a question about coolent. every time i add coolant close to max mark, after 2500km-3000km driving it drops to close to min. no warning light. is all turbo like that or do i have a issue to look into.

your dealer is nicer than mine. My local dealer quoted me something like $1200 to do the same job but fortunately I know an indy who drives a BMW every day. He charged me $5-something so I think your dealer is in the ballpark. Apparently you have to remove the intake manifold to R&R the filter housing. I didn't want to do it myself so I paid... hope this doesn't start a trend.

I've heard horror stories about oil leaks that get on the serp belt causing belt failure... not a big deal in and of itself but apparently somehow the engine can suck pieces of shredded serp belt right through the front main? I've never heard of such a thing on any other car but I've seen a couple threads about this with the N54.

I'd be more worried about loss of coolant, a modern engine really shouldn't use any coolant at all, at least not enough that you'd notice it between regular flush intervals.

This is awesome this is exactly what happened to me minus the pieces of the belt getting sucked into the engine. I just replaced the belt and will address the oil leak from the oil filter housing soon.

I have an N52 and I didnt have to remove the intake manifold to replace the oil filter gasket. There's a DIY on here if you search for it. I replaced mine, took an hour to two. You remove the intake, the alternator and just have to work around that tight space.

There is a DIY, it is not a difficult job overall and you do not need to remove the intake manifold, except if the annoying bolt on the back of the housing strips. You do need to flush (at least partially) coolant.

It is not urgent matter, but you should have it done nonetheless, as the gasket has a tendency to shred and debris can contaminate/clog the coolant system.

Additionally, oil and water can mix, and since you see coolant level drop, it is very probable that you are indeed having water going into your oil, especially if you see no leak or white smoke.

I clamped off both coolant houses attached the the oil housing and removed them. removed the Air filter box and snorkel. That gives you a lot of room to get to the two odd ball bolts.

N54 is pretty different. You do need to pull the manifold out a couple of inches in order to get clearance to the bolt.

Most of us N54s also have the thermostat housing for the oil cooler which has a gasket that should be replaced at the same time. The bolts to remove the thermostat housing from the oil filter housing are also hard to reach and take some time.

All in all, this is something you will have to fix regardless so it makes no sense to sit on it until it gets worse.
