That does look cleaner!. My Cam cover has a gasket. The hardest thing was making sure that the timing marks were in the right place. I don't have a heater and I got tired of that outlet pipe disitegrating, so I turned a new one out of 316 stainless....

Thanks D!
The front of the engine isn't leaking.. Back of the motor, and the front of the gearbox is..

Yes thanks, I've already got one. I just want to verify that this is the problem. The stupid engine's already been out twice now for inspection. I want to make sure that this is the last time.
P.S. Thanks for the info DD!

Thanks for the reply but there is no groove, it's a fresh motor. I didn't measure it because it wasn't scored, but it didn't look machined. I am thinking now that it must have been machined undersized at sometime. I'd like to verify what size it should be versus what it is.

Does anyone know what the A14 Crank Big End Diameter is supposed to be? You know, where the rear crank seal runs. Also, the diameter of the FS5W60A main drive gear where the front oil seal runs.... These are both leaking badly even though they're both correct and brand new...

I am running two Mikuni HSR42 carbs. So far they are excellent! The Throttle response is awesome and no flat spots. Super easy to tune. Large float bowls and an accelerator pump. Fit on standard Mikuni, Weber or S.U. manifolds.......

Thanks!

Does the aluminum H-145 diff center use the same parts as the Iron one? Specifically the Pinion flange and the crush sleeve.
