what is this bolt?
I noticed something a little weird one day when i was examining the engine while idling. I'm referring to the 19mm large bolt head that is on the top of the crankcase just next to the edge of the cylinder head. The photos were taken from the driver's side.
Well to me, it looked like there was some oil seeping around the edge of the recess in which the head of the bolt lays (it didn't look like it was coming from the edge of the bolt). I first noticed it when I saw what looked like tiny bubbles forming at the edge of the recess. After I noticed it, I cleaned it out with a rag and that hasn't really happened again but my questions are; What is that bolt for? and What could could it mean if indeed the oil leakage in that area became profuse? I guess I'd be able to answer the second question myself if I knew the answer to the first! Thanks |

well, you didnt tell us what vehicle this is... but it must be a 240d or naturally aspirated 300 series, right?
that 'bolt' is a cover, I believe. Underneath it is another that used when removing parts related to the timing device and IP. |

its a common leak area.
you can loosen it and replace the o-ring underneath. |

Not a problem taking that "cap" off, nothings going to jump out.. Underneath is your oil pump drive and intermediate shaft.
I dont know why you couldn't make a gasket from gasket material, you dont need any special "O" ring.

I would not recommend "just taking that bolt/cap off"... Best to blast it with a hose or compressed air to get rid of any crud that might fall in the hole first.
