22nd just passed emissions inspection this week good for a year,
Next job getting and gathering more project service parts for BMW Box. More Research,
had intake manifold off,
use magnetic inserts in your 11mm socket for manifold nuts,
I dropped 1 nut in between starter and block, gone forever,into abyess, as oil filter housing o ring failure, that 1 bolt under manifold runner,exxon valdez front of engine began this project
replaced oring gaskets on manifold hard and dried out ,Ellring OE FTP
replaced 2 vanos sensors and valve timing solonoid also bad o-ring leaking
Walnut blasting intake valves was in real need@75k perfectly clean now went thru timing order, time consuming project ,
slow going many layers of oily carbon looking paste gunk covering intake ports and valves all fresh now,
HF blaster hopper,walnut blaster metal adapter tube, BMW clone vac nozzle for intake port ,e bay , small shop vac, valve blaster nozzle tip adapter for hf gun and a box of fine grade walnut shells and a spray can CRC Turbo intake valve cleaning solvent, lots of compressed air and clean rags , CRC solvent help dissolve the stuff walnut shells would not reach well, valve pockets held liquid solvent so valve seats clean sealing good.
Pulled intercooler degreased cleaned , piping had lots of oil in intake tract, visably apparent why intake tract contaminated with oil from emissions stuff dirty design for emissions compliance, looking for a catch can setup for a clean e chassis mounting bracket setup for E84 N55
Charge pipe broke on removal as it was stuck on intake ,tugged it broke so new vrsf charge pipe installed too
vrsf turbo aluminum intake piping better quality and diameter so it will breathe better, soon
RK or new {MHD? researching android flash tune appl}? RK recommended by local dealer parts guy,Tune for E84 N55 35I 6cyl , wish i knew this when i had intake off send ecu into bench flash it. now i might not have to?
