Recently picked up a 1995 F-350 Crew Cab Long Bed as a project truck. Doing pretty much a ground up restoration as I am pulling the bed, cab, and front clip off in order to paint the whole frame. Have to pull the motor to replace a oil pan gasket or front main seal (not sure which it is yet) and I'm wondering if I should just go ahead and rebuild it since it will already be out. I don't plan on making big power with this truck, just a few easy power adders. It is going to be pretty much a weekend toy truck and not see a whole lot of miles. The truck already has a banks intercooler and a trans command system. I plan on installing bigger injectors, straight pipe, head studs, tune, and a water methanol injection system. Seller claimed the motor has 220k and the trans has 150k but had no paper work on either so could have as many as the odometer says which is 320k. Motor doesn't burn oil or coolant and runs strong. No signs of being down on power or weird noises (rod knock, spun bearings, etc.). Thing starts right up even in the cold and not having the block heater plugged in. The reason I'm curious whether or not it's worth rebuilding is because I plan on lifting it 13 inches and putting it on 40's so It would be a heck of a lot easier to rebuild it now when it's lower than having to pull it and rebuild it after it's sky high in the air.It's my first diesel and I know they are all known for running up big millage on the odometer and everyone I've talked to said the 7.3 is easily a million mile motor but just want to avoid the headache of lifting it that high then something going wrong that could have been prevented when the motor was pulled the first time and trying to figure out how I'm supposed to get the motor pulled a second time when it's that high in the air. Let me know what y'all think!!

 

Take the wheels off & pull it or do it now . Rebuilding it guarantees you nothing .Check the compression ( Leak down test) & go from there.

 

X2 if its runing fine why screw with it, just reseal the whole engine. Check compression and come back and show us the numbers
Just make sure to post some pics of your rig

 

You lost me at the 13 inch lift....what? It's a million mile motor IF meticulously maintained and taken care of. Check your compression and go from there.

 

Alright I'll borrow a diesel compression gauge from my buddies shop and report the numbers I come up with back to yall. Unfortunately the one I use on my jet ski's and dirt bikes only reads up to 300 psi other wise I'd go get those numbers your you guys right now. I heard 350+ is good and 320+ is acceptable as long as its evenly spread. Any truth?

 

Get the numbers
