Later model Porsche 944's use alloy arms with "non-rebuildable" ball joints. Folks are getting them re-built with grease nipples installed. Don't know any details (it's easy enough to just buy a good used one), but the know-how could already be out there...

Many thanks for the thermostat housing (m20b25). It was nice to meet you and also check out your work. Without this part I would never of been able to detect the leak in the radiator! AHHHH

Many thanks, the oil cooler head arrived superfast and in prefect condition.

Big thanks to Mark for supplying me a very good replacement cylinder head (m20b25). He even soaked up the cost for a new valve and a helicoil job for one of the exhaust stud holes. Head came complete with Pressure Test certificate with the date etched on the side casting. Great service all round. A+...

A friend recently bought a 1991 318i that has the wrong exhaust fitted - no cat and the AFM doesn't have a mixture adjuster. Would an earlier unit with mixture control function ok or is a pre cat ECU needed as well.

Any info would be appreciated.
