Vanos problem

Hi,

The Rod bearing issue on the S54 was
engines built FEB 2001 to JUNE 2003.

S54 also came from the factory with different
size Conrod Bolts, the larger ones, which
in my opinion are the better version, are
only found on the real early S54 engines that
were built in 1999 and 2000 although they
sometimes appear in cars registered in 2001.

Its interesting that the S65 runs an almost identical
factory spec stretch Rod bolt as the smaller S54's
ones, and happily Rev's to 8400 without issue.

I'll bet the Flat Plane Crank in the P60 had some
special bolts fitted in those V8 Conrods for sure.

I have always run ARP in the S54's but does make
you think.

Back on thread, have you been supplied with a
loan Car or is your Warranty limited to Mechanical
repair and replacement parts only ?

Regards,

The Gorilla.
