The car smokes on start up (with little knocking) and stops when warmed up, thats when the knocking actaully become noticable. The idle does shake a little here and there, but much better since the "bad fuel" is gone.

I can not hear any knocking on start up. As I wrote before...the knocking only started after I took a long drive to "clean out" the rest of the bad fuel.

When I "crack" the metal valve lines to release their pressure....all the injector lines except number two actaully cause the idle to stagger.....when I open line 2 the knocking stops.

The car never lost oil or its pressure....who knows how long it had been since it had been changed though. There does appear to be a lot of "old" gummed up oil in lots of places though (glow plug holes...alda line) and I think I mentioned before the car sat for quite a while before I got it.
