You have a smoking BMW due to bad valve stem seals. The valve stem seal problem is that the old valve stem seal becomes hard over time and doesn’t provide the proper seal between the seal and stem. This allows oil to pass through and enter the combustion chamber and exhaust. The oil consumption here is bad for a lot of different reasons. Obviously smoking, but also decreased catalytic converter life. We’ve seen a number of cars that have set CAT inefficiency codes and these codes can go away if you replace the seals if done in time.
Use the AGA N62 Valve Stem Seal Tool Kit. Perform the Valve Stem Seal Repair without removing the engine, cylinder heads, or cams. This repair not only saves you hours of labor, but also eliminates having to have thousands of dollars invested in cam timing tools. This is one of the few tools a shop can buy and recover the cost already on the 1st job performed.
Eliminates smoking from the exhaust, reduces risk of damaging cat converters and plugging the secondary air injection. It also allows the car to pass Smog. No need to remove Intake or exhaust cams or buy expensive valve timing tool. There is no longer a risk of setting the cam timing incorrectly. Plus, you have the assurance of being able to sell the valve stem job to the customer, rather then having them go to another shop for the repair.
NOTE: Valve Keeper Installation Tool is included with the Valve Stem Seal Tool Kit
