Make sure your pressure switch isn't the source


Your rings may be leaking, I would do a compression test on each of the cylinders....

Do you mean the oil pressure switch?


Ya .. but I only read "OIL LEAK" and not the part about i smoking /// sorry


smoke could indicate a large carbon build up in the valves. are you loosing oil while its doing this ? and does the exaust smell like a chain saw would ? cause if oil is mixing in the cylinders it would mix with the gas like a chain saw the smell is very distinct.
