Satish and Rich,
Many Thanks for your posts. Armed with these I'll be going to my =
mechanic this afternoon. The poor guy is at his wit's end trying to =
figure this one out. Will keep you posted.
Happy new year. Hope this year bring the best that life has to offer to =
each and everyone of us.

Well, it's probably incorrect plug wire positions on the distributor =
drive.=20
I assume this is a pre-1996 119 engine with dual distributors and coils=20
correct? I doubt compression is an issue. Cam timing is relatively easy =
to=20
check after pulling the valve covers.=20
I'm betting that it's the position of the plug wires on the =
distributors.=20
Check those carefully against a diagram. Note that some wires from the=20
right bank route over to the left distributor and vice-versa. I'll bet =
this=20
wasn't done.=20

I Have posted the message on the R129 list but since I am not a member =
of=20
the R129 list I fear that my post will not get through. Those few who =
have=20
transplanted the an M119 engine to their W126 SECs might be able to =
offer an=20
insight.=20
Anyway, the problem is that my mechanic is working on a R129 that needed =
a=20
valve job. After he refitted the heads back, the car in question has no=20
power at all. It starts and idles fine but has no power once on the go, =
if=20
the accelerator is floored ---- no power. I will be visiting him next =
week=20
to personally drive the car and see what could be the problem and to =
help=20
him do a bit of trouble shooting.=20
A few things already in my mind are to go over the cam timing, correct =
plug=20
wire fixing and a compression test. Any other points that come to mind =
would=20
be welcome=20
=20
Thanks in advance.=20
