I think my 6.9L is having some cavitation issues so I'm considering just dropping in a brand new crate motor, does anyone know if you can still get a 7.3L IDI crated and who/where has the best prices?
I've been told from unnamed sources that with the new foundry process (International can do a run of a single block because they can make castings on the fly on a per run basis) that when you get a reNEWed engine (that'll be the International branded rebuild) they occassionaly are new blocks. Basically, it seems that if they run short on blocks getting bad cores etc they will make a run of them to keep up the supply. However, you *cannot* request or otherwise buy a block like that for a re NEWed engine specifically.
I don't believe International lists a new engine. I believe a 7.3IDI will be a D-444, but I'm not sure. A DT-444E is the International version of what ford called the PowerStroke.
International contracts with Delco Remy/FPP for the V-8 engines.
Apparently Ford discontinued the part number and got rid of what engines they had in the supply chain.
I don't know if Ford can get reNEWed parts, but International dealerships can easily enough. Scout Light Line suppliers can as well, but don't know if they can get more medium truck type parts easily or not.
Some International dealerships aren't very friendly if they realize you aren't getting a big truck part, but the 6.9 and 7.3L engines were used in a lot of dump trucks. The international spec'd parts will also be heavier duty than original Ford ones (this remains true today, one reason why a new Ford might have an issue that International trucks don't).
This information is mostly from a diesel mechanic I know, some of it is a mixture of information gathered since I'm big into the International vehicles.
I have some white smoke that I only see in my mirrors at night on the highway, coolant missing and I smell coolant sometimes too, I basically know there's gotta be a small headgasket leak, I try not to drive the truck till I can pull the motor and regasket it but i'm considering some other options also while considering the cavitation factor and all... also the other night my antifreeze was low and I saw some white bubbles/clouds in the radiator and wasn't sure if that was oil or just bubbles in the coolant, filled it up and haven't seen anything in the radiator yet that I would think would be oil and haven't seen those white clouds anymore either
When the head gaskets are getting ready to go, look for coolant around the rear two glow plugs. #7 & #8 cylinders tend to get most of the oil coming out of the CDR, which raises the cylinder pressures in those two cylinders. The head bolts stretch and let coolant seep out or compression to seep into the cooling system.
Servicing the CDR every other oil change or more often can prevent this problem.
