Common oil leaks

Post by Nightsman33 » Thu May 12, 2022 9:57 pm

What are the most common causes for oil leaks on the 3.0 diesel please guys.
I noticed today what dont look fresh a fair bit of oil on the plastic cover on the bottom.
Do these engines suffer with rocker cover gasket like most Bmw or is there other things to look for. mines a 2007 last of the E53 model made
Many thanks

The level sensor in the sump is the only oil leak i have had on mine (2002) in the 5 years i have had it.

I’ve never had a rocker cover oil leak on any BMW I’ve owned (six so far). The only oil leak was on the power steering on my E53 due to a faulty hose (a known issue in 2004).

You can get oil appearing on the covers after an oil change if the filter change resulted in a spill,
:ant: Never anthropomorphise computers. They hate that.

Oil leaking from rocker cover on e70 is common id imagine the e53 is the same. I definately have the start of an oil leak I think is the rocker cover on my e70 but these are a nightnmare to change as all the injectors need to come out , goodluck with that after 13 years and near 160k :rofl:

If it is the level sensor you have to drop the oil so it is best to do that job when doing the oil/filter change.
My e53 3.0d has done 175k and that is the only leak i have had while in my ownership rocker is dry as a bone.
