Jim;
I just read in John Horsman's book "Racing in the Rain" that Cosworth
recommended sprinkling a handful of Ajax cleanser down the injector
stacks when their newly- assembled DFV engines were started up the first
time on a dyno. They did it and the rings seated almost immediately.

Subject: Engine assembly goo
It seems like everyone has their own ideas regarding this procedure but
it
all of the results are either positive or theoretical. I have tried
something that didn't work. In the old flat head days I thought it
would be a good
idea to use valve grinding compound for engine assembly, the idea being
to
smooth the metal and reduce friction. In every motor the horsepower
started
immediately diminishing after start up until the engine came apart. I
tried
different grades of grit but experienced the same results. I
eventually
switched to a Chrysler hemi and Valvoline 50 weight for assembly and
got much more
power and engine life.
