Oil leak

[JaretE90]

Howsit gents, I recently spotted some oil marks where I Park my car, definitely coming from the front. Havnt had the time to look at it just yet but any suggestions on what it could be? Or what are common places for a 320i e90 to leak oil? I drove from ct to pe for holiday so im still here and wanna get it sorted before heading back to ct

tappet cover gasket or vacuum pump seal at the back of the head would be my bet.

Have a look at the little tray above the exhaust manifold, if its full of oil then you have your answer.

Hi there. I have had a couple of 320's and still have one. Okay. Starting at the top.....tappet cover gasket approximate cost to repair from agents R1500 next is the vacuum pump o ring again appropriate price R850 then there's the sump gasket. This is the priciest one running in at around R2450 . There could be other items such as the sensors on the front of the engine. It would be best to get it in for a check up. You don't want to run out of oil with these engines. Hope this helps.

Dip stick tube seal is also a common issue.

engine oil...?
or hydraulic oil ?

a mate of mine actually had a crack in the sump. initially we thought the sump plug was leaking because the oil seemed to come from that area. upon closer inspection.. found a tiny crack. just a bit of draining, brake cleaner and pratley sorted it out

We dont have dip sticks Giz.

Another common problem on the e90s is the oil filter housing gasket. These tend to become extremely thin, and thus cause a lot of sweating of oil coming through. This then drips down the front of the engine. If you do an engine bay wash, and and degreasing chemicals were used, small amounts of this oil end seeping through the engine and in the floor.

However, checks all the factors especially the tapit cover gasket.

If is auto, then its possibly the plastic oil sump. They tend to warp with heat over time.

I do have the auto 320i. Its leaking alot now, so havnt even tried driving it. Il have a look at it what u all suggest and get back to you all. Unfortunately its that time of year and everyone is closed till the 4th. Really appreciate all your guys input. I hope you all have a happy new year and be safe if you out on the roads

I think my sensor might be buggered tbh, on the drive to pe from cpt the hole way my oil was between min and max on the display, after finding out my cars leaking oil after afew days in pe, I check the reading again after driving the car and it now displays the oil on max, so I have no clue as to how much oil is in there. Il add a pint before driving the car to the mechanics

The oil seems to be coming from the back of the engine, cant get in there to have a look[CRYING FACE]

If you are in PE, take it to Auto Classique, ask for Jason. They have a site. But phone today and book for tomorrow.
