I bought one thinking of running the 6.0 route. But my buddy just told me about a 7.3 that i'm going to check up on pretty quick. Was wondering if and what I should look for with the scan gauge?

Thanks,
Brian

 

Well, if you can show up and look at the truck with the engine completely cold, a buzz test might give you an indication if there are any worn injectors. Of course if it does have worn injectors, the owner will have likely started it and let it warm up so it doesn't show the symptoms of having trouble with a cold start. A cylinder contribution test might also be useful, but there would likely be other symptoms you would notice for that test to be of much help.

Otherwise I'd say scan for codes, pull the lid off the air filter and inspect the inside of the tube going back to the turbo for any signs of dirt or dust. The inside of the tube should be spotless. Dust inside the tube is bad and means you need to look at the turbo wheel for signs of dusting, or possibly check compression. (drop in K&N filters are known to be an issue on these trucks). Also check the stuff in this thread. https://www.ford-trucks.com/forums/5...questions.html

 

The link Chris posted is a great start.

I posted this last week. The thread was about someone considering the purchase of an ambulance.

"I wouldn't consider buying it without being able to hook up an appropiate scannner and checking for codes. I would clear all codes and do some live data-logging to include tranny operation, and then re-check for codes. Not all codes mean big trouble. Some problems that cause codes are cheap and easy to fix.

If it checks out during data-logging and code checks then look down in the valley for oil. Oil in the valley wouldn't be a deal breaker but would mean some repairs are needed".

 

I was looking more towards what "data" to log. The 6.0 guys hade checking delta temps (ect/eot) the ficm volts ect. I had a few 7.3s. I feel at home with them haha! But thanks for feedback.

Oh and this is my 1,000th post woooo ^_^ someone buy this guy a beer!

 

How about a pitcher. Here you go. On me.
