Putting the new crankshaft housing cover on the 740, noticed that the gasket (Victor Reinz) is just a few mm longer than the cover. Are the ends supposed to be bent inside, or just cut off before installation? There's high temp RTV silicone that goes on the bottom edge (no oil pan gasket there).
Thanks!

Glue/seal the gasket to the housing and trim off the extra length. I use a dab of sealant where the bottom of the housing meets the oil pan. What do you mean -- "there's no gasket there" ??? -- of course there is--or it got ripped away taking off the housing. If none--cut a new section and glue/seal it into place. If the motor is out of the car--remove the pan and replace the entire gasket after bolting the timing cover into place. -- Dave

Yes, the part of the oil pan gasket touching the cover is gone, from the previous work done on the car. The part was glued with silicone sealant. That’s just one of the misfortunes of this motor, I must say. Can’t say for sure now but it didn’t seem like the silicone gasket was leaking.

I guess a new oil pan gasket to cut a piece out of wouldn’t cost me much in terms of either money or time (I’m redoing a lot of things on this car, so a few days wouldn’t matter either way). Would a cut piece make for better seal than just silicone?

"Would a cut piece make for better seal than just silicone?" I would say yes having done that many times but that may just be me. I don't want to have to think about the glob of silicone squashed out and breaking off inside the pan. -- Dave

OK, how about this solution:

Seems like the coolest jigsaw puzzle I've ever tried.

What I'm thinking is raising the engine/tranny a couple inches and supporting by the motor mount brackets. Not as much trouble as pulling the whole assembly out, but enough to get a new gasket in.

Should in that case silicone be used WITH the gasket?

Thoughts on that?

I would cut the section needed from a complete gasket--or gasket paper--and reassemble with a little sealant coating the gasket and especially in the corners where the spliced piece meets the block/cover junctions.
While complete gasket replacement would be most preferable it's not quite a simple job and I'd only do it if other work was needed. To get the pan off completely means lifting the motor more than a few inches and also allowing the crossmember to drop by loosening the mounting bolts all to clear the oil pump. That means having the car up on jack stands at the jacking points and raising the motor with a hoist or bridge. If you don't remove the pan completely it's a very tedious job working through the gap to get the multi-piece gasket installed, especially if the old gasket needs scraping off.--Dave

Secure the gasket to the housing and then trim off the extra length. I use a little smear of sealant where the housing + gasket meet the oil pan. What do you mean - "there's no oil pan gasket there" ??? -- of course there is, unless it got ripped away when you removed the housing. If none is there and the motor is still in the car you will have to cut an new section and glue/seal it into place. -- Dave
