CSL Mileage...

[csl9000000]

Am hoping to push the button soon on my 3rd CSL.

Provided they have been maintained well is 70,000 miles something I should worry about or are they fine beyond this.

Anyone have any experiences?

Thanks

Currently sitting on 73k.
I would not worry providing it has history.
I've had to replace the head gasket @ 71k but thats really about it.

Mine is at 66k now, the head gasket was done at 63k, But mine is running great.

[glendog74]

Mine is 78k now.

HG replaced around 70k.

Car fine since.

[cslsuperfan]

70K

70K absolutely fine but SH a must.
Mine's on 60K awaiting HG failure!!

81k FBMWSH and pulling like train.:smokin:

[sjb]

65k and head gasket being done right now but that should really be the only serious mileage related issue I gather.....

[Yanto_csl]

73k

Leak down test before Munich...

Tighter than a..........:supz:

[mattCSLnut]

89K with FBMWSH :thumbs: Still running on original engine with original HG :smokin:
Engine oil & filter changed every 4K miles ... or at least once a year.
Gareth did a compression & leak down test last year and it was bang on speck & tight as. :supz:

Why do the head gaskets go ? How do they fail ?
On regular M3s is this usually a problem above 100k miles or 50k miles ?

Presumably M3 CSLs are seeing this at 60k miles plus because they have been driven very hard on track ?

Mines on 85000
Head gasket changed at 89000 :hahaha:

I'll post up a photo of a failed S54 headgasket I have at work tomorrow.

I'm on the lookout for a lo wish mileage CSL at the moment and this gasket problem is a worry. Is it something that's been cured on later examples?

I've also seen reference to floor problems. Does this indicate abuse/track day cars?

jim
dont worry about the sub frame problems, most have been fixed now and if they havent dont buy it, mine has had a relatively easy life with no track action and it still cracked its not if its when !
regards to head gasgit how long is a peice of string ?
if you are buying get one with full warrenty you would be mad not to as a small trip to the garage could be more than a year of payments !
saying that mine has been nothing but a pleasure to own, forget milage go with history and the way the car ia presented.
you will know if its a stinker !!!
i allways look at scuffs on the rear seats dont know why but if they are all scuffed up i think its a shed.

I remember the old BMW M20 6 cylinder engines were notorious for head gaskets

Stuart Draper's M3 I thought did 170k on the original engine needing NO head gasket work well from what I read in Total BMW's E46 M3 buying guide in 2012 :-)
