Where's all this oil coming from ? 951 Di GTX

[Jonnyivy]

Well I have to hold my hand up and say that I was probably right about putting too much oil on the big ends after my crank re-build. I took the head off today to see to another problem of a tiny amount of water leaking from the head gasket. When I/we took the head off (after starting it for a few seconds only, both cyliders firing then back onto only one).. we immediately noticed that underneath one side of the head was drenched in oil !! The other cylinder(the old original one) was dry but this wet one is the new piston installed along with the re-built crank. I put a 10ml syringefull into both crank basins and smeared it up the cylinder walls when I rebuilt it about 6 weeks ago.
This is most likely why this new cylinder dies after 10 seconds ? so how do I get the oil out ? If I crank the engine with the head off will it throw it up eventually ?
I know there's not 'loads' of oil down there, but there's obviously too much....
Any suggestions ??/
Can this cylinder be 'sucking' the oil I put into the seperate counterbalance shaft ? (40 ml) or can the injection oil 'seep' from the resevoir and pass through the injection pump while the engine is not running hence gathering oil in the crank basins while it sits in the garage ??
Just a thought....does the jetski really just need a good 'blow-through' and give it a good hard revving instead of being gentle with it when it starts ???

take the ski out in the grass and flip it over, it'll drain out.

Is the oily cylinder the rear one? Have you ridden the ski after the rebuild or is this the first few start ups?

The oily cylinder si the front (mag) one. Thats the one that siezed and melted onto the crank pin. The casing has been welded , but was only a hair-line crack. I can't think of why there is so much oil in there. The rebuild went very well with no problems , and most of the time during the larger fittings there were two of us at hand to see everything went correctly. The engine turns over very smoothly,.. it turns no problem with the starter and there are no funny noises when it does eventually start up. When both cylinders do fire up, there's plenty of smoke at the tail end, but most times it just dies down onto one cylinder again ( I presume the oil is killing the spark ?) Off coarse there is still an issue with my thinking that there is a lack of fuel to that cylinder too, but as yet I aint figured it out yet.
Much appreciate the help,..
Thanks,

John
