12valve front cover reseal
So new hear. I have a question is the fel-prep front gasket kit any good or should I get a different one. I worked for Cummins or Cummins shop for year and never thought twice about it until I priced one recently.
Fans
I know this is a more mundane question and I wasn’t sure if this should go here or in the bullshit corner. It’s regarding an12v so here it goes. I’m looking at a 94 fummins truck and the previous owner bypassed the engine fan and shroud and put a pair of electric fans in its place. The all aluminum radiator seems large so I’m pretty sure it took up too much space to keep the stock fan. Opinions seem to be divided on how well this system works long term. Does it depend on the brand or if I get the truck do I need to plan on rearranging everything to get a fan back on the engine? Thank you
Rocker Arms
I am unsure if I can reuse my rocker arms but they are not cheap these days so I was hoping someone could chime in and tell me if these need to be replaced, need to go to a machine shop if I can find one that knows what they are doing, or if they looks good to go. They feel smooth and slide on and off no problem. This is my first rebuild on this project 96 12 valve. Any advice or guidance would be greatly appreciated.

1997 Dodge Ram 3500 – 12-Valve Cummins (P7100) – Need Help Diagnosing This guy explains all my problems almost to the T. https://www.youtube.com/watch?v=1xUy3NF_Ma8 I've been chasing a fuel-related issue for a while now, and here's the timeline. Truck cranks no start starts with ether/starting fuel Took it to a shop they diagnosed as an overflow valve. Changed that and same exact system Fass system installed. It works because i tried bleeding and it getting to the injectors. Shut off Solenoid is functional Idle Screw has been adjusted At this point i'm not sure what this issue is. I plan on taking it to a different shop that specializes in diesel. I don't want to wrench it on anymore... I'm exhausted all my options Any diesel mechanics or recommendations in the seattle area?

1997 Dodge Ram 3500 – 12-Valve Cummins (P7100) – Need Help Diagnosing I've been chasing a fuel-related issue for a while now, and here's the timeline. Original Symptoms - Truck would randomly stall when put into reverse. - Replacing the fuel filter would temporarily fix the problem. What I Tried - Replaced the mechanical lift pump. - The truck improved but would still stall occasionally. - Increased the idle speed with the idle screw, and that seemed to solve the problem for a while. Problem Returned Eventually, the same symptoms came back. I repeated the previous repairs, but this time nothing fixed it. FASS Conversion Thinking the factory fuel system was the culprit, I: - Deleted the factory fuel filter housing. - Removed the mechanical lift pump. - Installed a block-off plate. - Installed a FASS fuel system. Current Symptoms - The FASS primes with the key and supplies fuel to the P7100. - The truck will not start on diesel alone. - It starts immediately with a small amount of starting fluid. - Once started, it will sometimes idle on its own, but other times it needs throttle to stay running. - Without starting fluid, it only cranks—there's no attempt to fire. After spending a lot of time troubleshooting, I finally decided to take it to a diesel shop for a proper diagnosis. Based on this timeline, what would your diagnosis be? I'll update this post with the shop's findings once they call me.
