Sump cover gasket

Clean the surfaces well. Sometimes it takes some solvent like lacquer thinner to remove all traces of old gasket. On the new gasket I would use white lithium grease, probably no better than anything else, just a personal favorite.
 
As with any oil bearing cover with multiple fasteners, tighten them all the same amount. I use an in/lb torque wrench. I used to use 80 in/lbs on all my M6 fasteners but all the talk around here about reducing the torque amount used on lubed fasteners (I anti-seize all my bolts), plus the fact I'm dealing with a 40 year old machine, has me reducing that amount now. I'm going about 70 in/lbs lately and may even eventually try 60.
 
I use Hylomar blue on the cover, a bit of grease on the gasket facing the sump. Those surfaces cannot be too clean.
 
Yes, you want and need to get them eat-off-it clean, remove every last little bit of old gasket and sealer. I use paint stripper.
 
I smeared anti seize on my sump gaskets and the sump plate literally just falls off now when I remove the bolts to change my oil. I couldn’t believe it the first time. If you’re looking for ultra oil tight, it might not be the best though.
 
I re-use my gasket as many times as it will allow. It will eventually start "sweating" oil but unless it starts dripping, I'll continue to use it.
