Hurt the old 673 this weekend

Recommended Posts

So this weekend i was going to drag the race trailer out of its storage spot and get some work done. I plugged in the old B and let her warm up for a couple hours. When I turned her over she fired almost instantly but I had a nasty popping coming from the intake. I shut her down right away and pulled off the valve covers. The pic shows what I found. #6 exhaust valve is very sticky in the guide, if I force it open, it takes about 30 seconds to a minute to come all the way closed again. So, the heads are off to the machine shop tomorrow, and the injectors as well. Anybody know where I could get a couple pushrods, the intake is bent too, just not as bad? I knew I should have gone through the top end before I started running her..... :SMOKIE-LFT:

It has been quite an ordeal, but I got the old girl up and running again. Turned out both heads where cracked, and all the valve springs and valves where worn out. found a couple heads that where already repaired and machined and a couple new push tubes(Thanks Fifth Wheel...). While I had it apart I had the injectors all rebuilt, built a new wiring harness(maybe the lights will stay on this year), and replaced every piece of hose in the truck. She will now hold some air pressure overnight! I'm off to go get some heat in the motor so I can re torque the heads... :SMOKIE-LFT::twothumbsup:
