Hi all,
I have a 2007 m6 black on black with a little over 90k miles. It spun a bearing so i decided to rebuild the entire engine. Including new piston rings, main and rod bearings, vanos pump rebuild, and so on...
Putting everything back together went well besides the tricky timing set procedure. There is close to no info how to set the timing on the s85 engines. I set it and used the timing check procedure and it looks spot on.
After engine was done i go to start it and it cranks over, catches around 500rpm, then dies and spins from the starter. I tried the DME CAS sync procedure but it doesnt help and i doubt it will because i am not getting any codes. I did get a vanos oil pressure code once so i removed both vanos lines, put them in cans, cranked engine, and they instantly filled with oil. So my problem isnt the vanos pump. Something strange i did notice was the passenger exhaust camshaft is very jumpy when cranking the engine. I was thinking maybe the vanos adjuster unit is leaking so its making the camshaft bounce and not let it run. I changed and it its still the same. No start, Just cranking barely to 500RPM. I have even changed the starter thinking it was weak and still the same. Could it be a shutdown of the injectors for whatever reason?? I get no codes in Ista except for transmission adaptation because i changed clutch and slave cylinder but to continue the procedure it says to start the engine. Any help or tips would help. Thanks
