I Have posted the message on the R129 list but since I am not a member =
of the R129 list I fear that my post will not get through. Those few who =
have transplanted the an M119 engine to their W126 SECs might be able to =
offer an insight.=20

Anyway, the problem is that my mechanic is working on a R129 that needed =
a valve job. After he refitted the heads back, the car in question has =
no power at all. It starts and idles fine but has no power once on the =
go, if the accelerator is floored ---- no power. I will be visiting him =
next week to personally drive the car and see what could be the problem =
and to help him do a bit of trouble shooting.=20

A few things already in my mind are to go over the cam timing, correct =
plug wire fixing and a compression test. Any other points that come to =
mind would be welcome

Thanks in advance.
