Z3 rust ??? Corrosion??

[ZippyZed4]

According to what I read on t'interweb ( a well-known fount of truth ) it's a condition that applies almost entirely to the M54 2.2, possibly something to do with the first owners of the 2.2 not feeling the need to scream about for the initial few thousand miles, and this may have encouraged the formation of gummy deposits around the oil control rings. However, that's according to the web, and may not be entirely based on reality.

I decided not to buy it, I knew I would get the answers I needed if I put the questions out there… it’s my decision but I thank you for your input, it was the interruption I think I needed… I have another Z3 on the drive and the Z4 coupe conversion in the garden… did i really need another project!!?… NO!

2.2 need exhaust checked.
2.2 and 3.0 have primary and secondary cats flanges between the 2 can rot really badly ( need Zedshed or specialist repair if they go as parts no longer available.)

Thanks, I didn’t know this… good to know going forward, I will probably get another Z3 … maybe in the Autumn

I've had both a Z3 2.2i sport and a Z4 2.2i and neither used much oil. Drove down to Spain twice in the Z3 2.2 and didn't need to top it up at all! My Z4 was on 120k miles when I sold it and rarely needed topping up.So not all 2.2 s use a lot of oil.

Thanks Z Victor 1 …. I just want to take a roadtrip to Spain now

@Jam03 have you tried using a slightly thicker oil 5w40 or 10w40 ?

No, not tried that. I’ve just come to accept she drinks oil. I guess it might also be down to how the car was run in or how it’s been used in the past. My car went through a long period of very low annual mileage in the last 10years. I’m not really bothered about it anymore.

Nothing to lose in trying then

I've tried using thicker oil, didn't seem to make any difference to the consumption. Which is annoying. Tried running some engine flush in it a couple of times, didn't help. If I was the young keen chap I probably never was in the first place I might consider taking it to bits to see what's in there, but the thought of the expense puts me off. By the time I've got all the gaskets, head-bolts, bearing shells etc it'd be cheaper to keep putting oil in it. And a damn sight easier, too. Which is good.

If it's not spewing out blue smoke from the exhaust then I wouldn't worry about it.

I agree with Duncodin
neither of mine seem to use much oil, so I dont worry about it.
Mind you I don't do lots of miles
