H2odiesel: injection timing check is next thing on my list, although the car runs fine & the cam timing is perfect.

Muybweno: I don’t know where the bleeder valves are on a 1978. There should be a removable bolt/plug at the uppermost point of the system – look for it in the vicinity of the thermostat – but again, I am *not* an expert on this, this is just an (semi) educated guess.

Thanks guys!
