hello im new here, i recently picked up an 85 m535i, ive researched everything i could find about the car and i keep getting mixed info about the engine,
the vin code is DC71, so is it the "dirty" hc motor or not?
and also why is it nicknamed the "dirty hc motor" around here? should i be worried?

Calling it a dirty engine merely means it's the high compression (10:1), 218hp version that wasn't officially sold in the US. Assuming your car was Federalized when it was brought here by the original owner, a catalytic converter and other equipment was installed so the car will meet emissions.
I saw your car in the other post, looks nice! Where did you get it from? At the 5erFest convention in 2005 in S. Carolina, someone showed up with a red M535i that was for sale but as far as I know no one bought it then.
