i have a 2001 B18c1 gsr motor in my EM1. The motor is fully built with following mods:Skunk2 pro2 cams, eagle connecting rods, weisco high comp pistons with 12.5.1 compression ratio, aem adjustable cam gears, full skunk2 valve train, the head has a 5 angle valve job, apr head studs, skunk2 intake manifold, jdm cold air intake, comtech headers, custom 2.5in exhaust catless with a vibrant muffler.*Just hit about 8k miles on it nd started smikng a little, not black but white smoke. Im tuned on hondata s300 but as of rite now i deffinitely need a tune and a minor valve adjustment. Any suggestions or info. on what my problem might be??? Thanks

 

Complete a leak down & compression test.
The issue could be valve stem seals, piston rings etc.

 

thats what i was thinking about doing. take my head to levines machine shop, nd have them put new seals. but do u think i could be smoking because i need a tune, my car only smokes when i take off then its normal

 

The tune can't solve mechanical issues. If the car is running too rich, that's one thing. But this issue is strictly mechanical. no programming or tuning can solve your issue.

 

This is how I remember it...

black smoke=burning too much fuel
blue smoke =burning oil
white smoke =burning coolant
