Looking for OEM engine technical repair information

jadkar · 12-22-2022, 08:21 AM

Hello everyone. I am completely rebuilding a N55 at the moment and I cannot find anywhere a source for comprehensive OEM factory repair procedures for the E92 N55.

The only place I found is BMW by a rather expensive subscription.

I have a virtual machine version of TIS that I use for my E46 M3 race car but that only goes up to 2007 and the E92 N54. I am using some of that information but now I'm balls deep in the longblock of this N55 and I want real N55 data.

Example is right now I am trying to find proper piston ring gap tolerances. Sure I'll probably be fine with the N54 tolerances but I'd really want to know.

There's gonna be other items I will need as well and I was hoping someone here might have a good source for this information.

Any help would be greatly appreciated!!!

Does ISTA+ have that information? I'll check for you after work if it's there for my car.

Lol BMW TIS...... $2500 a year.
