How did you set the timing after re-installing the distributor?? Sounds to like the timing may be too fast.

I have a '81 Firebired that did the same thing with the factory-issued Flintstone-mobile 3.8L V6. Everything but the starter worked correctly: new 185 thermostat, perfect 50-50 coolant misture, no leaks, etc., but still had to wait 1-2 hours for a cool down.

It may be that your original starter is dying. Your starter relay is over-heating and opening the circuit. You can replace the starter and/or buy a pre-made heat shield for the starter or fab one yourself. Regardless, just remember that the goal is to keep the starter as cool as possible.

To prove this is in fact the problem get the engine hotter than usual in your driveway then shut it off. If it won't start cool it down with a bag of ice (don't burn yourself). Should take less than 5 minutes to cool it to start.

Good luck!

If that motor doesn't have hydraulic lifters, try loosening your rocker shafts. It will clatter, but it will run. That's what I had to do on my old slant 6.

If you have hydraulic valve lifters, then one or more are leaking down which increases valve clearance. Put a can of lifter cleaner in the oil and drive it for a while. If you have solid lifters, just adjust the valve clearances.

Is there a lifter adjustment on 3.2 Isuzu motor


this engine uses hydraulic lifters or lash adjusters as honda calls them. if there is noise, you must either perform the tsb from honda 97-076, or replace the lifters. you can check them by removing the valve covers and slightly rock the lifters back and forth to see if there is abnormal movement. there should be slight pressure against the cam lobes at all times.
