As the pistons rise, the breather valve closes, and the opening at the timing cover would be the path for the air to get sucked into the crankcase.

I had no intention on doing that because of the different vacuums and pressures in an engine.

Anyway, try plumbing some air to the oil tank vent fitting on the case, see if that'll blow out of the timing plug hole.

I agree.

Also agree with the grease idea, have done it many times on experimental aircraft engines (which sometimes could take months to disassemble).

After sealing the plug with permatex gasket seal I went for a 200 mile ride thru the mountains Saturday without even a weepage. Thanks for all the good advice, jokingly or not.

Good to hear If there is just enough threads that Permatex stuff can work well.
