CSL Mileage...
 

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.

Mine is 78k now.

HG replaced around 70k.

Car fine since.

70K
 

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

81k FBMWSH and pulling like train.:smokin:

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

73k

Leak down test before Munich...

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

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 ?
