What Diesel Do I have?
Hello All!
Im usually in the '04 and newer section but I need some help Id-ing an older truck. The truck is either an '84 or '85 F-350 Dump truck. Its a heap, the reason im asking is im going to pull the engine out to use in another truck. The vin tag is very corroded and i cant get the drivers door open so im not sure about the vin. Some folks think its a 7.3 but i didn't think that motor was out then. What do i got??
Thanks in advance!

I personally don't know the answer to your question however you might be able to take a look around the diesel forums for pictures of people's engines (or post a pic yourself) and be able to ID it that way. Just a thought. Good luck

I am almost certain that it has its original engine. So it must be the 6.9. Things been sitting at my shop for almost 5 years. I put some fresh fuel in the tank, put 2 jumpers on it and the thing started right up! I was able to drive it right into my shop. Sounds really healthy.
My next question is will this engine be able to be transplanted into a 1994 F-SUPERDUTY 1.5 ton? That truck had a 7.3 non turbo diesel in it. I am removing the 6.9 carefully and am saving every wiring harness from it. I have the engine out of the '94 already and did the same, saved and labeled all the wiring. Will this work or should I not even try it?
Thanks!

Original 6.9 glow plugs would burn the end off if powered on just a bit too long, while some of the newer glow plugs can survive a 20+ hour torture test, without failing or falling apart.
Glow plug tips entering the combustion chamber can be very ugly.........

Both the 6.9 and the 7.3 IDI plugs will burn out if left on for too long, but they usually don't swell up and break the tips off like you mentioned - this is what happens to Autolite and Champion plugs, they are the ones self-destructing hardcore. Wellman plugs seem to hold themselves together too, at least mine did a while back - two burned out, but neither got deformed and fell apart, all 8 plugs came out rather easy.
