I'm swapping the transaxle in my 924S for one with a LSD from an early 944. Since I want to keep my short 5th gear, I'm doing a 5th gear swap (http://www.944spec.org/944SPEC/techn...-5th-gear-swap).

When it comes time to replace the rear cover of the transaxle, I've got a new gasket to put in there. After cleaning the mating surfaces, should I install the gasket "naked"? Or should I put a thin layer of gasket sealant on each surface? Is there any reason not to apply sealant?

Thanks,

Mark

Yes, a sealant should be applied.

The factory did not intend for a sealant to be used for the rear cover, just the gasket.

No need to use an additional sealant, its not a common place to weep or leak. I have never used any and have never noticed any wetness there. But it would not hurt to use a sealant in addition to the gasket.

FWS manual: "gear carrier assy, coat sealing surface with original VW sealing compound D3"

5th gearset is accessed by only removing the rear alum cover on the back of the gear carrier.

Sealant is used on the diff cover and the gear carrier/case mating surface (shown in green). The rear cover requires a fiber/paper gasket (in blue), item 8 page 34-15 of the FSM.

OK.

Thanks everyone. I'm just removing the rear cover (blue line) to get at 5th gear, and I have the gasket. Will try it without sealant.
