Good luck with it and I hope you get it straightened out pretty fast and that it isn't anything serious.

Tx79chevy · 09-07-2013, 05:39 PM

show your friend that piece,could be the issue
under the entire distributer cap is the rotor which has a thin strip of metal,it comes up to contact the bottom of the actual plastic cap of the the dizzy
looking up inside you should see a little round metal bump(contact bushing)
if it's flat it's wearing out,can still work tho

Update: Got my truck back today. The teeth on the gears for the timing chain had been sheared off. The original gears were still on there.

That's not good news.

Did something stop turning?

What's your next step? shop for a crate motor or fix this one?

I know you must be bummed outs since this is a new truck to you.
Just hand in there and you'll get it sorted out.

Get a manual and post pics and questions here.

Original late 70's thru 80's gears were poly/nylon so teeth sheering after years of use is not unusual. Pop a new steel gear & chain on & it's back in business.

Tx79chevy · 09-20-2013, 12:58 PM

Yeah it had the original nylon gears. He put new gears and chain on it and it runs great now.

This is why I asked if the rotor was actually turning. Broken timing gear or chain = cam not turning = distributor/rotor not turning.
