Thanks, I plan to upgrade the headlight harness to take some of the load off the 30A. I also found the terminals on mouser for the fuse block so I'm going to replace the bad ones as they are pretty arc'd out. These are silver plated as well so should be a little better with contact to the fuse...

I believe the cast iron rockers were like 83-84. Maybe 85 too? Mine was an '84. This was what mine looked like coming out of the engine. Had about 70k miles on the engine and all 4 shafts had ~0.030in of wear where the bushing was running. All scored up beyond repair. I can't say I'm too...

Hi All, I'm having issues with my fuse block melting around the terminals for the headlight fuse as well as the heater blower motor fuse. I know these are somewhat common issues. Is there a part number or option to replace the plastic cover all the terminals press into? Or an alternative fuse...

Well I broke a valve spring and was a pretty close to dropping a valve from the looks of it. Luckily I shut it down before things went too off the rails. Long story short, when I pulled the rockers to repair the spring I also had a cracked rocker shaft and the old style bushing/cast rockers...

Hi All, My turn signals and tail lights work, but not my brake lights or rear hazard lights. I have power out of the brake switch at the pedal and every once in a while the hazard and brake lights start working so I know it’s a loose connection. Looking at the diagram it looks like everything...

Well I finally got around to putting her back together. I ended up machining up a set of retainers for the stamped type rockers to get the best of what both types have to offer. No chance of broken rocker retainers and no oiling / shaft failure issues. A little better than the grade 8 washer...

Popped the top off the pump....this its what was in there....pretty sure the weight retainer shouldn't spin independently of the main shaft and have so much slop. I'd say she's toast. https://youtu.be/028iCfToxbk

Thanks for the input guys. I'm talking with Scott over at Oregon Fuel Injection as it seems people have had good results there. The pump that is on there is a 4267 pump. I know that's not the military number which I believe are obsolete. Its HD civvy one so I think they are more or less the...

Ya I think the ring has failed and it just hasn't run enough to see debris from the ring. The local injection shop quoted $900 to do the pump so I guess I'll be finding one online since that's pretty steep for a POS rotary pump.

Well after replacing all the valve springs on the drivers side bank I pulled the injector pump cover off and there are a bunch of metal shavings in there. They are ferrous and stuck to the solenoids. From what I could see the governor assembly looks ok, but with the shavings in there something...

Good info. Sorry, I didn’t see your post in my other thread. Just took a look and no tag on the pump. It was supposed to be a new rebuilt one when the shop did it 8 years ago but I was 400miles from home so I was more focused on getting up and running than what specific updates were done. I’m...

Engine Over Revving When Started Hey guys, I'm having a problem that just popped up recently and resulted in a broken valve spring. Now that the valve spring is taken care of I am back to troubleshooting the original issue. When I start the truck it acts like the pedal is floored / its running...

Well I put a new valve spring in there and she runs normally now as far as the knock and misfire go. Still revving when started. Now that its back to a working engine I can start troubleshooting the rev issue, but Ill start a new thread for that since its pretty specific.

Shot you a PM with what I'm looking for CUCVRUS. Thanks!

I was surprised to see they still sell replacement bushings for the cast rocker arm assemblies. Rock Auto has them as Sealed Power 3863Y

That's what I originally thought, but since it doesn't blow any white / blue smoke or look like there is oil leaking from the valve guide I'm thinking it might be something else. Once I have a chance to get the valve spring changed out I'll post an update.

Thanks cucvrus. I'll shoot you a PM once I have had a chance to inspect everything. From a quick look the rocker shaft is broken and it looks like there is pretty decent wear in the bushings of the cast rocker arms. What are people's thoughts on the newer style stamped rocker assemblies? Since...

As discussed in my other post I am in the market for parts to fix a broken valve spring and broken rocker arm shaft. Can anyone recommend where the best place to get these would be? It looks like rockauto only carries stuff for the new stamped style rocker assemblies. They have the valve spring...

I did some more work today and found some stuff. First off, no smoke (other than black). I have to start it and throw it in gear to keep the revvs down. When it sits there trying to go in gear both pipes are blowing some black, but nothing out of the norm. I pulled the drivers side valve cover...
