    e34 535i down on power

    hello i have a 1989 bmw 535i and it has an eradic idle at about 1100rpm but when in drive goes down to about 450rpm it smokes a little bit of white smoke/steam and is down on power wont even spin the tires it also throws a 1222 code with the stomp test

    edit: found that it had skipped 3 timing teeth!!! and she still ran! previous owner was an idiot, told me he had changed the head gasket but i don't think he did even that right, my oil is starting to get milky maybe its because it was off 3 teeth? any help is appreciated

    Sounds like you have it figured out, blown head gasket and improper timing.

    Skipping 3 teeth.. and it still ran? That's a data point.

    If you want a look at engine function I'd suggest a compression test, or better, a leak-down test. But if you are getting milky oil most would think it's a bad head gasket and you'll have the opportunity to examine piston tops and valves then.

    Your mission, should you decide to accept it, is to add value to these threads, either by pictures or by descriptions, so the next person with the same or similar problem stands on your shoulders.
