I decided some time ago that I was going to make my '94 F350, seen in my avatar, my new service rig. I am shooting for a balance of economy, power, reliability, longevity, and durability. I want it to pass anyone I want to loaded and pull whatever I hook on to with ease. I've been collecting engine upgrade parts for a couple years now, and I finally tore in to it. This was the original plan:
New head gaskets w/ ARP studs. Updated valve seals. No head work unless necessary. Hypermax has some IDI valve train parts I'm curious about.
Cam (R&D IDI performance Stage 1)
Hybrid 093 turbo system (R&D IDI performance) w/ 3" turbine outlet/down pipe upgrade
Exhaust-3" down pipe to 4" straight (ATS/MBRP)
Intercooler (Banks Technicooler)
Custom air filter system. Not sure what it's going to be. I will figure it out when I get there.
Coolant filter
Injectors (Not sure what kind yet. Open to options)
Injection pump (Not sure if I will just turn up the running one I have or upgrade. Still making up my mind. Open to options.)
Upgraded lift pump system if needed.
Later on swapping in some 3.55 gears for my 4.10's. I plan to make enough power that I will not miss the 4.10's. And, then If I think I need a little more gearing a ZF-6, but most likely not until the ZF-5 is worn out.
I had hoped and planned for that to be all. My plans changed when the heads came off. I found three cracked pistons, cylinder walls with little to no cross hatching left, and four pistons that look like they got a little hot and started to melt a little right wear the precup enters the combustion chamber. I was not happy or impressed. It ran great prior to tearing down. I was just going to do a top end build and figured being well taken care of all its life and in great condition for its age and milage that the short block part of it would be in good running condition. Also, recently I have had a small amount of oil in my coolant. I will make a pressure tester for the oil cooler to make sure that's the issue.
Now I know "This thread is useless without pictures". I'm going to try and figure out how to get them on here.
So, the new plan is to keep going pull the engine tear it the rest of the way down and make it right. It's hard to see the piston damage I'm talking about. I will try to get some better pictures later.
