Base gasket leak

[bobgroger]

I had some oil weeping from the copper base gasket on the Trippivot 1260. Since I switched to the 750 oil pump gears it has worsened to the point my right boot is coated after a few miles. Since I don't want to do this twice looking for some advice from the engine gurus....
Copper or Fiber base gasket? Brand? Sealant?
Copper or MLS head gasket? Brand?
Is there an O-ring around the head studs where the oil gallery is? Didn't see one in the diagram.

OEM Base and Head gaskets

Ha Ha ; where to get those for a 1260?

You know, I MAY be able to use an OEM base, and I have one. I have to take it apart to verify but PO said the sleeves are necked down so the cases don't need to be bored.

The 1150 base gasket is nice and probably seals better than a copper base.

If you can get a recommendation from RapidRay that would be your best bet.

Ray cuts (with tin snips) 1150 OEM head gaskets for 1166's, I had one from him but I'm not real sure how it does it as well as he does.

My 1166 would piddle a drop now and again from right at the front. I got everything else sealed and could finally ride without getting soaked.

I vaguely recall the 1150 head bolts providing better/different oil flow through the gap between head and bolt OD.

I used a pressure bleed-off to reduce the oil pressure a bit. HD gears will easily peg a 15 PSI pressure gauge. I had a sprayer to shoot oil at the stator and reduce engine hear from the stator.

Both teh Series R/R and stator cooling help in this regard.
