Many people consider blue smoke from a vehicle to be elusive. Blue smoke is generally caused because of several specific conditions in the vehicle's engine. We will help you determine what the problem is so it can be corrected and stop the blue smoke.

burn oil, some engines have a small oil drain back holes in the cylinder heads, these holes allow the engine oil to drain back into the oil pan. The oil is picked up by the oil pump and returned back to the engines vital parts under pressure. If these drain back holes become plugged it can cause oil to seep down into the valves and into the combustion chamber. To repair this problem remove the valve cover and clean debris from the drain back holes, reassemble and recheck (note: after repair you must wait 2 to 4 days before the remainder of oil on the valve stems to be removed).
