Really?! I’ve heard of this with Millers but never Castrol.
That is interesting. *scratches head*

It sounds like your mate was somewhat overcharged for replacement cams and followers. Did he go OEM or upgrade?Ed Doe wrote: ↑Tue Aug 11, 2020 5:00 pmMy comments re flattened followers, scored cams, Rod bearings and head gasket are all direct experience either on mine or my mates late model e46 m3, as are the costs quoted.ph001 wrote: ↑Tue Aug 11, 2020 9:40 am I think most of the costs have been a little overstated to be honest, and camshaft / lifter failure is very rare indeed. Vanos / bearing shells I guess eventually will need doing but tons of facelift M3’s are way past 100k miles and still on original.
Roof motor relocation is £80 from Durham Dave, although I would recommend keeping it where it is and just pulling the bungs.
Water pump not an issue.
ABS pump refurb is £200 from ecutesting, with lifetime warranty.
If you are prepared to DIY the brakes then can easily be done for significantly less than a grand.
The insp2 is pricey for what it is, and in practice it’s very rare for the shims to need replacing... more often than not it’s measurement error as the tolerance is incredibly tight. Many get adjusted needlessly.

After several forum threads about Z4Ms needing new cams and followers, I asked my Indy what would be the cost to replace both cam shafts and all the lifters in the event of failure. Bearing in mind that he has first-hand experience of doing the job previously, his price was ‘around £1500’. That was about five years ago, so even with inflation it shouldn’t be over £2000 now.
I’m aware of half a dozen Z4Ms that have had new cams and followers, and a similar number that have spun bearing shells. Most were not regular track cars. I think “very rare” understates the frequency of these, but I do agree it is not ubiquitous.
Can't argue with what your saying, I just don't get how a similar percentage of failures are not seen on the M3. Given there are at least 10 times the qty of S54 engines in that car you think you would see a similar pattern but there doesn't appear to be (cams & followers I mean). Maybe it runs slightly hotter in the Z4M or something but I doubt it.
You might be right about supplying parts since it was a hypothetical conversation around swapping to Schrick cams and followers. Apparently, Schrick buy OEM followers from BMW and do something to manipulate the case hardening such that they are less prone to fail. As such, they would be my preference even with OEM cams.Ed Doe wrote: ↑Tue Aug 25, 2020 12:11 pmNew oe cams - £1,546BMWZ4MC wrote: ↑Tue Aug 25, 2020 11:14 am It sounds like your mate was somewhat overcharged for replacement cams and followers.

New schrick dlc followers x24 - £1476 (oe ones are even more expensive at £107 a pop!)
Fitting (including head gasket): £1580
Not sure where you're getting your costs from but guessing your indy was quoting based on you supplying the parts!
Fwiw it's possible to reduce the fitting cost by several hundred if you don't do the head gasket and instead remove most of the front end to get the follower tubes out. In my case I'd rather have my pistons inspected and know the head gasket is good before bolting it back up and getting on track again.
Also ironically the schrick cams are a couple of hundred cheaper than oe new ones - but when you factor mapping in it obviously becomes a more expensive route again.
Perhaps a greater proportion of E46 M3s have been used as daily drivers covering more motorway miles whilst more Z4Ms have been used for weekend hoons and as track cars. Or perhaps it’s reporting bias, since this forum sees a reasonable proportion of the total number of Z4Ms whilst there isn’t a single cohesive, definitive E46 forum.ph001 wrote: ↑Tue Aug 25, 2020 1:09 pmCan't argue with what your saying, I just don't get how a similar percentage of failures are not seen on the M3.

Nah they're same as the e46 m3. The acs z4m supposedly had csl cams but the normal z4m intake manifold apparently but no z4m was mostly normal e46 m3
