Intermediate shaft cover gasket

I have some automotive gasket material and I was wondering if it is necessary to purchase a gasket made specifically for Porsche or am I okay with the generic material.

I have some Loctite 574 as sealant


The IMS flange on the M96/97 engine's uses in internal seal, so no gasket is necessary:

I believe this is my last question.  Do I need to put sealant on both metal surfaces, with the gasket in between?


Questions are what we are here for.


The answer to yours totally depends upon the condition of the metal surfaces; if they are perfectly true and free of imperfections (scratches, etc.), the gasket should be enough without sealants.  However, if there are marks on the metal surfaces, or the surfaces are not completely flat, a small application of sealant would be advantageous.  Just don't go nuts with the sealant, you would be surprised at how often we find gobs of excess sealant jamming up oil pump pickups.

I found out by laying the cover on a glass surface that it was not perfectly flat, but close. Spent a hour sanding it down with 150 sandpaper. So do I need sealant on both metal surfaces?
