335i engine question

bebik22 · 10-15-2013, 10:19 AM

I have 335i 2009 which was having misfires. I wanted to change spark plugs so I opened engine cover. Once engine cover was removed I found seeds in the location circled in red on the picture. What is that hole for, next to coil/spark plug?

I don't think it's for anything. Some debris is normal in that area from driving around.

Pretty sure the hole is a relic of the casting process.
Seeds might be from a mouse/chipmonk that was caching things.

ok, thank you guys. I tried same question on 2 other bimmer forums but no answer, this site is the best.
I started taking car apart to figure out why it shakes on the cold start and got distracted by finding seeds at location I was not expecting. I guess will change spark plugs first.
