308 defect has boggled experts. Help !!!

Gary i belive you got your problem solve a simple cam timing being over looked, by the way did you ever get your tach working with the MSD's

 

You started out with the words expert mechanic...right?

 

Help me out here. How do you "invert" the way you've been timing cylinders? They're all on the same bank, right?

Unless you mean they were connecting the wrong spark plug wires coming out of the distributors or other ignition into the wrong cylinders.

If that's the case. You should probably have taken it to Midas or Brake Masters before this guy! j/k

 

Assuming that it still has two distributors, they were probably hooking their inductive timing light to cylinder #8's plug wire instead of #5's for the front bank's timing.

 

I had similar symptoms to yours, but intermittent ('85 308QV). It would appear severly for an hour or so, particularly when negotiating windy roads with short busrst of accelaration, and then possibly settle down.

After a long search the problem turned out to be a leaking cam seal beneath a distributer, so that maybe a tablespoon or so of oil was sloshing around in the distributer base. Easily fixed, and immediate relief.

 

You could not have done any worse yourself. Next time do the job yourself and Fchat will talk you through it!
