Mille oil drama....

Chaps, just dug the '02 Mille out of the garage after the winter lay-up and it started up almost straight away. I left it to idle for abot 3 mins until it got to 62 degrees at which point it cut out. Thinking that it had just stalled, I tried to turn it over again but it would not start. I then noticed the oil light was on and on checking the oil level, noticed it was at minimum. I then noticed that the coolant tank had about a 1/3 rd of a litre of 'clean' oil in it (clean as in no 'mayo-type' consistency). WTF is that about? It ran fine at the end of last year and I know for a fact that I haven't put oil in the damn coolant tank.
I'm hoping nobody is going to say head gasket / cracked block either
After it initially cut out, it sounded like it was trying to start but just wouldn't catch so it isn't seized. Would the oil sensor on a Mille prevent the bike from starting if the oil is low?
What do you reckon my plan of action should be? My plan is to get some more oil, top it up and try starting it again (....gently) whilst keeping an eye to see if any oil starts filling up in that coolant tank

Oil sensor just indicates low oil pressure.

If you have Oil in the water it could be 1 of 2 things

1.The water pump oil seal has failed - The shaft that drives the water pump has two seals 1 to stop oil getting into the water and the other to stop the water getting into the oil.
2. Head gasket failure

I would if it were me not try starting it but give Griff at AP a call on Monday and discuss with him.

Most proberbly head gasket failure :eatcorn as said there are two seals on the water pump but theres a drain hole between the two so unless both seals have gone & the drain hole is blocked it's unlikely the oil getting into the coolant there.

Thanks for the replies. I've decided against trying to start it again and am going to get it looked at by someone who knows them inside out.

Recommend these?

Thanks again

Ah the Jaffa muncher himself !, Yes Griff is a living god when it comes to fixing Apes, He's crap with women and beer though.........

If you want to know if he's any good, buy a copy of this months performance bikes, they ask him when they want to know about aprilias. So apparently, he does know a thing or two.
