Friend has a new rebuild, question is does engine assembly lube burn white smoke while it is getting cycled through the engine and for how long will it do it if its the luuuube? Motor is getting broke in and has prob 50 or more miles (i cant remember he didnt specify.) Could the white smoke be caused from old old gas? About 5 gallons of 91 oct. was dumped in and there was prob 2 or 3 gallons of a desent amount of old 91 octane... Exhaust doesnt smell sweet like antifreeze but i might be wrong, Checked the spark plugs and they are normal, took a light to the pistons through the spark plugg holes, all are clean, so im not thinking its leaking a shart load of antifreeze in the cylenders if thats the case.... Any ideas post em.
