i dont think 180 out on cam is a problem,because if you turn the
crank another revolution its going to be in time like the book says.
ive seen guys dabble some silicone on the oil pan and leak,an oil free
surface and a bead of sealANT THAT SQUISHES OUT A LITTLE IS BEST.
rings,valve seal , crankcase ventilation or oil leak cause oil loss.
those honda black engines are about as cheep made as you can get with
that plastic camshaft setup.
