226 overbore sleves

   let me get this straight in pankey logic.

#1.  was water leaking past the sleves into the oil getting so hot in 15 seconds that it was turned to steam and sucked out the exhaust.

#2.  was a leaking head gasket, leaking water into the cylinders.  But there is no water at the head gasket and the engine is a dry block.

#3.  excessive blowby that waits untill the end of a run to appear.  Continues when the engine is at idle and cylinder pressure is low.  This doesn't make sense either.

What will # 4 guess be?  A magic Genie?  Make a wish spankey!!!! maybe she'll give you a brain so you can think before posting

Well it's # 4

 It is oil smoke.  The crankcase breather was hooked to a plug I made that fit in the oil fill hole on the old magneto drive.  Timeing gears would sling oil up at the hose, the crankcase evacuater would eventually pull some oil up the hose and into the exhaust stream.  It took a little time, hence my magic Genie would only appear after 12-15 seconds. 

I didn't want to hook the crankcase evacuater in the valve cover, it may hold excessive oil on the head and in the lifter galley.  Rember (again for the village idiot) the old 201 blocks were solid on the bottom of the lifter rail with the oil return hole in the front.  Unlike the 226 blocks that had wide open holes in between some of the lifter bores.  I suppose I could have knocked a hole in the block somewhere else and made a fitting, but that extra oil filler hole that needed to be plugged anyway was a handy place to hook a hose to.

It's simple physics explained once again for "jealous mitch".  High velocity exhaust gasses cause a decrease in pressure when passing an orfice.  That orfice is hooked to a hose to pull a vacuume on the crankcase to help seal rings and evacuate any pressure.  Oil is pulled up the tube after time and when combined with hot exhaust gasses a magic Genie appears. 

Please try and rember this "jealous mitch".  I explained it to you long ago and you were to dumb to understand it then as you have proven you are now.  Not learning even basic physics and jumping to conclusions will never get you verry far.
