Hi Tom !
It's strange that 150.000 km old Diesel has gone
(my R9 GTD has almost 225.000 km behind and I have
no problems with it), but I'll check one scrapyard
near Warsaw for F8M or F8Q engine in good condition.
This scrapyard specialises in French cars, especially
in Renaults. I have bought some good parts for my R9
there, and when I was there recently, they have two
R9s and one of them was GTD

I'm going to go there in the next two or three days
(I'm looking for some plastics for front right door),
so I'll have a look for Your engine.
Best Regards,
Peter
Renault 9 GTD '84
