Hello. I own a 6 speed manual BMW 2012 135i N55 with catless down pipes, Bms intake, stage 3 clutch, MHD stage 2, PR coils, 1 step colder plugs, single mass flywheel, and a vrsf charge pipe.

I recently replaced my valve cover for a new pcv valve and the hpfp and the o2 sensors. I had to do those fixes because the car was running way to rich and would have a rough idle and would go into limp mode when driving and would shit blue smoke out the exhaust when I let off the throttle and and let the engine slow me down.

After those parts were replaced I removed MHD from the ecu and then reinstalled it and reset all adaptations within MHD and changed the oil. After those changes it fixed all my problems and the car ran great for about 20 min. Then it broke up a bit while on the throttle and when I came to a stop a bunch of white smoke came out the exhaust. When further driving it would consistently put white smoke out the exhaust after driving then coming to a stop. I reflashed my tune and reset adaptions again and the car ran flawlessly again for about an hour. Then while driving at in town at about 30 mph it started to break up and bunch of white smoke came out the exhaust while driving and more when I came to a stop. Also my coolant temps would get up to 235 briefly while the engine temp was operating normally at 245. Also I checked my coolant reservoir after the first time it started smoking and it was empty. I refilled it before the second ecu reset and flash.

To me it seems that coolant is finding it's way into the engine possibly from a head gasket leak or a OFHG leak or maybe some kind of leak at the turbo.

I'm going to have a local shop look at it soon. Any ideas would be greatly appreciated.

Also after I reset adaptations and reflashed the tune a second time while it was driving flawlessly I took some logs. A few 3rd gear pulls and a 2nd to 3rd gear pull. Any input on these would be greatly appreciated.
