k guys my b18c is getting very smokey it had been over hauled only about 15,000 miles ago any way after a good bit of track driving its starting to be very smokey under full throttle driving also it hadn't been started for about 5 weeks and when i did start it , it ran on 3 cylinders for 10 mins and i noticed that the plugs have a bit of oil on them

 

Worn rings. Time for at least a cylinder hone and new rings, but depending on how much wear there is you may need a rebore and new pistons as well. When you're this far into the engine you might as well fit new bearings and check to see if the crank needs machining. Or, cheaper alternative might be a second hand engine...
