Yesterday I finished rebuild number 2, this time with new new pistons and piston rings and matching cylinders (at great expense from Heiden). This morning it started easilit enough then billowed blue-grey smoke - a thin haze on idle, then billowing clouds with throttle. It was coming from the left cylinder.
So, I took a deep breath and stripped the top-end again today, lots of oil in the exhaust port area and on the left cylinder on the piston and obvious signs of oil coming in through the exhaust valve. I fitted a new valve guide and lapped the valve again, cleaned up and put the whole lot back together again.
Third rebuild finished and started up first time - then billows of blue-grey smoke.
By the way, with my hand over the end of the exhaust (oil mist coming out) there was hardly and compression from left cylinder.
HELP!
I have everything torqued down to spec, new head gasket, hmmm! Help.
