Upper Timing Case Gasket DIY ??

So im planning on fixing my oil leak this weekend therefore im changing out my valve cover Gasket and my upper timing case Gasket, on my 91' 318iS.
Im pretty confident in changing my valve cover Gasket, BUT im not to sure about my upper timing case Gasket..
Does anyone have/know a link which has an DIY for changing the upper timing case Gasket for the M42? (with or without pics).
Any help is appreciated, thanks.

I think there was a diy on with all the part numbers included.

I had the same issue back in january. If i were you id also look into the lower timing cover as well. You dont want to do all that work to do it again when the lower chain gasket goes.

Also since you would have it all exposed id look into replacing the water pump, chain guides, and the front main seal. Again... You dont want to do double or triple the work when those start to go.

I decided to send it out to get done.

Gone but not forgotten

You will need to remove the water pump to change the upper timing case gasket. It quickly turns into a serious overhaul.

Along with what BMe30 said, you may also want to replace the chain tensioner, flush and fill up with new bmw coolant. I would also pick up a M6 helicoil kit for any stripped valve cover bolts, I had 4 or 5 and just noticed another recently
