I purchased a 2006 Jetta TDI with the BRM engine that had bad camshaft and lifters. I replace the cam and lifters, water pump, timing belts. I checked the timing as others have suggested by turning the engine over and two revolutions and reinstalling the timing tools making sure the cam timing pin slides in freely.
After the repair the engine idles rough and has some white smoke out of the tail pipe. Once the engine is up around 1500 RPM it seems to smooth out and is very responsive to the throttle.
I ran it about 5 minutes at 2000 RPM to break in the cam. Seemed to smooth out a little but still idles rough and has some white smoke out the exhaust which is likely unburned fuel from the rich smell.
It idle extremely rough before I changed the cam and runs much better but don’t like the smoke and rough idle. Both check engines lights are on.
Any Ideas
