UH OH. This can't be good...

Hey,

And happy new year, mine is not off to a very good start.

Was traveling down the highway tonite around 40 mph or so, not running it hard, suddenly the motor kind lurched and shut down.

After getting it home and pulling the valve cover off it was discovered that the cam sproket bolt had backed off and allowed the pin to slip out of the sproket and stop turning...

And while I was pulling off the cam gear, the chain tensioner expanded before I could get the screw driver inbetween the chains. I did get them spred apart...is that gonna be good enough or do I have to take the front of the motor off????

And when the motor was turning over in the garage to evaluate what was going on there were no major noises. This is the built motor with the tall cam.

I plan on pulling off the head to check the valves...

Any advice on the tensioner or the possible damage to look for?

This suks, I just had that car running awesome from the damn Chevron crap.

I'm about to give up.

Do yourself a favor, check that bolt.

After pulling the head, I think you should be able to shine a flashlight down inside the front cover and see if the tensioner has popped back into it's correct position, or is out of place. If you've been able to get your screwdriver handle all the way down past the tensioner, you should be OK.

Keep your fingers crossed! :classic: & Good Luck!

PS: Did the Cam Gar bolt loosen by itself or was the engine opened up by a shop when you had the poor performance issue from the bad gas resolved? Bad Luck? or Bad Work?

Thanks Carl,

I think it's a shot of bad luck, I am almost sure that a few valves are bent, I'm not sure how they could not be, the pistons are forged so I would be surprised if they took on much damage...

I'll be tearing it down later this afternoon...

Yippe.

Brian.
