THE PROBLEM This BMW equipped with the N63 engine had an oil consumption issue where 1qt had to be added every 4 days and was blowing smoke from the tailpipe with a blue tint when accelerating post-warmup. This is caused by the aged rubber on the valve stem seals that hardens and cracks which will lose its ability to seal the valve guide. Bad valve stem seals will cause excessive oil consumption and can be identified by recording the level of oil loss. This is unfortunately a common problem that has carried over from the N62 to the N63 BMW engine. The models affected are vehicles from 2003-2008 with N62 V8 engines such as the  E60 545i, E63 645i, E65 745i, E53 X5 and vehicles from 2009-2013 equipped with N63 engines such as F10 550i, F12 650i, F01 750i, and E70 X5. HOW WE FIXED IT We fixed it the only way you can fix this problem when it arises: by replacing the valve stems with new ones. First and f ... read more

We have a BMW F02 750 here with a twin turbo V8 N63 motor in for performance upgrades. The DINAN P1 Power Package is not your every day upgrade. Dinan pumps up this BMW to 507HP & 583 TQ.1) Stage 4 Software - 109 HP 96 TQ gains giving this N63 motor a total output of 507HP 583 TQ. Tuned for a smooth power-band to put down predictable and even power in all gears and throttle positions. This smoothness improves the quality of the shifting and the overall drivability. 2) CF Cold Air Intake - One of the most effective ways to increase horsepower is to install a cold air intake. The cold air intake upgrade utilizes the greater density of colder air that adds more flammable oxygen molecules per square inch and burns fuel more effectively. The Dinan carbon fiber intake looks as good as it performs, allowing more outside air to be pushed into the engine via twin-ducts while also providing structural stiffness ... read more

What is Walnut Blasting? Walnut blasting is the process of blasting pressurized, crushed walnut shells onto the intake valves and in the cylinder on direct injection engines. This procedure is designed to remove carbon deposits which accumulate over time from blow-by gases, carbonized fuel, and oil on the intake valves and intake ports of the cylinder head. When the valves become heavily carbonated, the engine may exhibit symptoms such as misfire, rough idle, and lack of power, which is a result of the intake valves not being able to close properly. Service Benefits With a clean running engine, power will be restored with a more responsive throttle and allow for an increase in fuel economy. We recommend to have this service performed every 30,000 miles on your BMW equipped with N54 and N55 engines, available on the 135i, 335i and 535i. This service is more involved on V8 motors such as N63 and diesel motors M57, N57 which requires a mor ... read more
