oil leak fixed (hopefully)

tom320i · 01-30-2019, 04:12 PM

Hi guys,
I'm new to bmw's and new here.
Recently bought a 08 320i with the N46 engine. Pretty happy with it, but it was dripping oil onto the exhaust. After some searching and reading, I removed and replaced the seals in the Vacuum pump. This post was very helpful in doing the task- https://www.bmwfanatics.co.za/showthread.php?tid=33222

But it is still leaking!
There is a vacant port that I noticed just below the vac pump. I'm wondering if the vacant port just below is supposed to have a plug in it, or maybe the rocker cover gasket is leaking?

Update- I found a pic on eBay of an engine with plug in place. So I raided a plug from the front of the head to put there.
Turns out it was M18x1.5
I've now ordered a plug from eBay to put in the now vacant port in the front of head. (Orig BMW plug was 3-4 weeks ex Germany)
Not sure why it was missing, maybe it fell out as the front one was only just over finger tight.
Hope this helps somebody.

May also mean the head has been repaired before

Keen to hear how you found the diy repair process for the repair of the vacuum pump seals?
