William's 330Ci ZHP Maintenance and Project Thread

I've heard about the relative stubbornness of the connectors in the power steering lines. I guess I'm asking if it's not wise to consider replacing those other lines since they're now 15+ years old, and I'd rather get them done in one fell swoop than repeat the process. If the other lines are unlikely to fail, then I'll just do the high pressure line. Thanks for your input!

If the marginal costs aren't prohibitive, I'd say go for it.

I think any high quality ATF should be fine. M1, Redline, Valvoline MaxLife, etc.

Yup, I use Mobil Dexron VI, just be sure to flush it while it's still red and you should be good

Rein used to make a replacement line but it had fitment issues so a genuine bmw is the only option now. Downside is that it's expensive. I bought one from the bmw mini parts store and used the coupon code Roundel.

Also at the time of replacement do a basic power steering overhaul. FCPeuro makes a kit with 2 lines and the reservoir since it has a built in filter.

As far ar removing the lines going to the cooler, the proper tool isn't expensive and makes the removal easier.

As far as engineoil, I would avoid brotella. I did an oil pan gasket on a car that had that oil for 20k plus miles and it's not a quality oil. Stick with mobil one or liqui moly.

Power steering fluid either redline atf or liqui moly atf.

Pennzoil Euro L 5w-30 is a solid oil according to some knowledgeable people on BITOG forums. Available at Walmart (either in stock or for pickup), too.

Edit: the oil is Pennzoil Platinum Euro L 5w-30.

What specifically? Just really sludgy?

Not sludgy since the oil changes were at a consistent interval. But you could tell that the wear on the metal surfaces was different. Maybe this is due to the types of additives in the oil. Less cleaning agents also is possible but don't hold me to that.

It seems like people that run that oil have some oil burning issues or higher miles on the engine.

Just for reference on my wife's car, I been running liqui moly since 116k and this is what the engine internals look like at 200k.

Looks pretty dern clean. I'm always open to other suggestions, I have no brand allegiance when it comes to motor oil. What Liqui-Moly have you been using (I'm not familiar with the brand).

Pennzoil also did pretty well on this youtube guy's testing. The oil he tested was the non-euro platinum.

Surprisingly, Liquimoly didn't do so hot.

Mileage: 77,434 miles

Did some fluid maintenance before I head into my internal medicine rotation for six weeks:

• Motor oil (9,905 miles / 1 year, 178 days): Replaced using Pennzoil Platinum Synthetic 5W-30, a MANN oil filter kit (MAN-HU9254X), and those two little green o-rings for the oil filter housing cap (11427549573). Collected an oil sample that I'll send off to Blackstone. Previously there was an elevated lead content.
• Coolant flush (21,108 miles / 3 years, 60 days): Replaced using BMW coolant (82141467704)
• Brake fluid flush (9,882 miles / 1 year, 177 days): Replaced using ATE SL6-1

Additional maintenance/inspection:

• AC system was emptied and serviced.
• Inspected the rear subframe/RACP for any cracks as I've heard a clunking over there but my mechanic said he couldn't see anything. Not too worried at the moment, but wondering if one of the rear shock mounts is loose.
• Inspected the power steering lines and the high pressure hose is definitely leaking
• Previously my rear brake caliper clip (34216753675) on the driver's side was found missing last March. Not really sure how it came off as I haven't done any brake work since 2015, and I know it was there around 2018. I purchased a replacement part and then I asked my mechanic to toss it on yesterday. When they were bringing the car around, it somehow popped off and gouged the brake rotor. I feel bad because he's now replacing the rear rotor, a NLA BMW Performance rotor (34212282873). He managed to find a pair in Virginia and BMW said it's potentially the last available in the US.
