Folks,

I have posted at various times since July regarding some difficult-to-top oil leaks. Well, after 6 months of steady trying, I got em stopped.

First, the "oddball sweating between the head and block" leak was stopped following advice of the forum. THANKS GUYS! I loosened all head bolts and re torqued and like magic, stopped the leak. This with the "do not retorque" Felpro gasket.

The oil pan leak that seemed to maybe be a rear main seal was tougher. It took 4 tries that included each time pulling the timing chain cover and resealing it too and replacing the crank seal, and replacing the rear main seal twice. Well, the problem was subtle. This time (I now have 3 oil pans so I can always have one gasketed up so as to speed things up for the expected failures!) I noticed the rubber seal at the rear of the pan seemed not well sealed in the corners where it rises up from the rear seal block to the engine block.

I rolled it up a little and sure enough, despite my having used a light clamp to seat the seal while the RTV dried, in those 2 corners some air pockets were left. So I eased the seal up along its inside and outside edges and squeezed in a thin bead of RTV, and opened up the corners and filled them, then I used the old finger to smooth over the inside and outside seams like you would if caulking a house joint. Let it dry overnight and bolted it up. Success!

SO, I would add to the excellent slant six forum article a caution to go to the trouble to seal the rubber seal corners and edges again before installing the pan (the corners of the rubber seal in the rear of the pan). Those of us who have wrestled an intractable problem to the mat can appreciate how good it is to drive, park and see no leaks!! I just kept telling myself "No", it doesn't have to leak! Now I can get on to tuning and back to the recurving project and adding to the emsvitil curves and bothering Rob with distributor oddities!
