The Random E46/ZHP Question Thread

Is this the correct part number for the RTAB? 33326770786

Any other bushings I can replace without dropping the entire rear sub frame? I am looking at the realoem diagram and I am confused...

33326770817 is the M3/Z4M version of the RTAB, you should probably get that one if you are sticking with OEM.

i would also replace the rear outer control arm bushings (in the hub assembly): M3 version is 33326775551, QTY4 (upper and lower, 2 per side)

Thanks Peter!

On the M3 the 33326775551 ball joint is on the lower and upper side, but for Non M's the lower is not actually a ball joint but can be used, as in an upgrade correct?

Not Peter, but yes - thats correct. On the non-Ms, the outer lower is a bushing. Its recommended to replace that with the ball joint that Peter suggested. I did the same to my car a few months ago.

EDIT: Part# 33306852895 supersedes 33326775551.

Guys... I need help.
Topped off my oil today, full synthetic, and she started acting really weird. Like not good. First the engine was sloshing it around making the whole car shake, then when it was trying to idle it jumped between 1k and 500 a few times before it came to a stop at 600(normal right?). Well when I revved it I got backfire for the first time owning this car, and it was this shallow gurgling backfire. Waiting a couple minutes and did it again and now it's throwing white smoke out of the back... smells burnt. YAY she's burning oil! Checked inside the oil cap:

There's buildup inside the tank, orange particles. Going in for an oil change on Tuesday now, but my brother is concerned that it's burning oil either due to a blown head gasket, cracked cylinder head, worn piston rings, cracked block...
I don't know anymore guys, I'm freaking out

Starting it up again now and going to drive it around for a bit, still backfiring after revving.
My other guess is that it might be bc I topped it off with Speedway synthetic, checked the last change and it was all Mobil 1, so it might be a reaction of sorts :/

Speedway makes synthetic oil?
