Don M.,
Is this procedure recommended for gas engines or specifically for
diesel? Someone correct me if I'm wrong - does the mechanical fuel
injection pump on an OM 617 motor stop all delivery of fuel when
'compression braking'? If it doesn't, and some fuel is still being
burned, then I expect that the oil leaking through bad valve stem seals
would also be burned and there would be no puff of oil smoke when
throttle is applied.
I don't know if it completely shuts off fuel flow, but going down hills
will reduce it significantly... Going down some hills my engine has
dropped below operating temperature... so I would imagine its pretty
close.
Does fuel even have to be burned? The heat to ignite the diesel is always
being generated... wouldn't it ignite the oil as well?
