Search 'oil pan spacer' lots of good info.

 

I've used 3M weather stripping adhesive ( the yellow stringy stuff) on valve covers, oil pans. and weather stripping. It'll hold the gaskets in place for installation. the gasket is what keeps everything from leaking anyway. Rubber cement, could work also. Ether one works great on cork, or paper gaskets. never tried it yet on silicone. Peels right off with acetone. Permatex, but that's stuff is messy, but cleans up with acetone too.

I have used Loctite 504 between the spacer and the block in combination with a stock nitrile/cork gasket between the oil pan and the spacer have ad no leaks with that arrangement. I would be tempted to use 2 gaskets with the new paper gasket design . The old style nitrile/cork gasket had way too much comprehensibility to consider using two.

 

Dreibond will work well in that location. You can cut it if you need to remove it from the pan later with a razor without too much hassle.

I'm pretty sure it's what Greg supplies with his baffle kit.

 

In the recent past, I've been using a thick black Mercedes "tar like" sealant between the spacer and the block. To get really good contact, I have been bolting on the pan with the spacer and this sealant and allowing it to sit overnigh (which essentially glues the spacer to the block.)
​​​I then remove the pan and install a cork gasket between the spacer and the pan.

Lots of effort, with some seapage on some early attempts (until my technique evolved.)
​​​​
I've been working on a gasket made from a special gasket material that resists compression and is very stable after initial compression. I intend to use this new gasket (different than the new gasket I'm making for the pan alone) on both sides of the spacer, in.order to get better sealing with less effort.

As with everything I develop and make...there is a tremendous amount of time, effort, and testing put into these new gaskets. It's a slow process, but I'm now close enough to talk about it..

 

 

Has anybody just welded the spacer the pan?

 

 

What would be nice is to have a spacer with a "lip" on it to keep the gasket in position. Mount the spacer to the pan permanently and the "lip" of the spacer would allow for slightly more torque but still keep the gasket in place.
OR
Have a spacer with a machined space for the gasket ala an O ring recess so the gasket was fixed in place and could move neither in or out
OR
if the original Porsche design had a machined block to fit into a machined oil pan to seal without a gasket (or the pan the fit into the block)

 

That would be a great idea! so would a billet oil pan. Years ago there was a billet oil pan made for the 928 block with a built in 3 stage scavenge pump for a dry sump build..... but it went poof.

 

I've learned that most of the people that own these cars, don't want to spend the money on them that's required. That's probably why that oil pan disappeared. If I don't have the extra cash, I wait till I do. I won't drive it till it's right, and tear it up.
