: I just rebuilt the engine in my 8n ford I align all the gaps in the piston rings because my freind told me if you line up the ring gaps that once you start the engine they wiil turn at different speeds and there fore never have blow by but my engine now blows the dipstick out evertime I start the engine HELp

With proper ring end gaps cylinder, bore finish , ring side clearance(ring to groove) and a straight, round cyl. the ring gap locations make little difference in blow by .
The reason being that when the engine is at operating temp. the rings expand to take up most of the gap.
