Dumb Question Thread - No Flaming Allowed

Anyone thats done a ZF swap, can you confirm that a 330i 5spd driveshaft works? I've gotten one with a blown out CV needing replaced. I may be able to test fit this weekend, but ideally I'd like to have a plan set before the trans is back in the car and then waiting on finding a new shaft. Timing is a bit short for me.

Thanks!

Yea I think it has gone out to pasture lol. Luckily it’s not hard to access, gonna put in a generic O ring from Advance and see how we’re doing.

Its not a typical oring size. I'd get the correct one using the part number unless you can find something close. Its a pretty fat oring. The fit is very very snug.

That is a significant leak for sure. I wonder if there even is an oring in there.

Here’s a video, I would blow into the area to clear the smoke and you can see how quickly it accumulates.

I've done something to my passenger side parking brake and I can't figure what is causing the drag/lockup, so I'm obviously adjusting it incorrectly.... Anyone want to shed light on how to do it properly, I'm tired of screwing with it and feeling like an idiot. k thx

If it’s a large enough leak yes it can cause drivability issues.

Been trying to un-fuck my other car little by little, I’m working on a series of vacuum leaks. I have a big leak at the base of the oil dipstick guide tube, probably that little O-ring. Do you guys believe a vacuum leak there could cause serious AFR deviations and drivability issues? Or am I likely going to continue to find more leaks downstream after I rectify this one?

I recently picked up a 2002 e46 with 98,300 miles that seemed to be well sorted with service records for rod bearings, VANOS, and basic regular maintenance (oil changes, brakes, etc). I took it to a reputable BMW shop here in LA who found the following faults/made the following recommendations:

- Leaking oil pan and constant pressure valve
- Brake and differential fluid flush
- Worn out engine mounts
- Valve adjustment
- Spark plug replacement

I didn't find service records for these and I wasn't expecting issues to pop up, so my question is whether these are known issues for a 98K vehicle and if there's a chance I'm getting taken for a ride by the shop.

How long ago was the VANOS rebuilt? typically a vanos rebuild should include valve adjustments, valve cover gasket, and possibly spark plugs.

Looking at having my axles rebuilt and/or buying a new set.

What is the difference between part numbers 33217839466 and 33207839468?

Your shop is treating you right. Every one of those is a maintenance item and nothing out of the ordinary for a 23 year old German sports car.

They really are. I ended up settling for a US one. Figured it's easy to swap a euro one in if I come across one in the future.

[Nate047]

Thought so, man these things are hard to find.

[heinzboehmer]

Is this a euro headliner or US? Need a quick dummy check

US. Euro ones don't have that bump in the middle.
