Who’s still using a 7.3 diesel truck

Others are reporting that switching over to Triax 5w40 oil helps to quiet down the HEUI system, I will be switching over to it next weekend if I get a chance, also installing a fumoto drain while at it. That should cure my weeping drain plug issue.

I should have been able to at least figure out the AIS. By the way I have 2000 F250 7.3 163K Been hauling a Northstar Laredo very well since 2008. Truck is built to F350 spec, came with camper package. Made four trips out west from AL. plus many trips on the east coast. Had two water pumps one glow plug relay and one overdrive actuator.

Re the water pump, there is a lot of casting material in the coolant passages of the engine that eats the seal or bearings. I had one go out about 60k miles, put a coolant filter on with the new pump. After a period changed the filter, the stuff that came out of the filter was beyond my expectations.

We have an 01 7.3 about 180k. I'm not sure about the noise referred to, ours isn't that loud inside?

I would enjoy this thread a lot more if I knew what a lot of the abbreviations were. CPS,AIS etc.

Keep your eyes peeled, someone is tossing a "stock" air box in favor of a "high performance" one every day.

Heck, probably gat some kid or performance dude to pay you a few bucks to trade.
I would not run a K&N on a turbo vehicle ever, in the first place and would look to swap it out in the future if I had your truck.

Fix the fuel system via 'harpoon' the tank and modify for fuel return and install oil pressure crossover. Did all this to mine and don't get the clatter, sounds like a smooth diesel. Also have the AIS installed. Had this on previous truck with 100k+ miles on the setup and never changed the filter and the filter minder only pulled a vacuum once when pulling a big load at max rpm in 2nd gear, but was still serviceable.

Steering box is a Red-head.

I got rid of the K&N filter on my truck and deleted the stock setup and put in an 6637 air filter, you can get the kit at riffraff or you can go with the AIS air filter. Short of really sound damping the cab the noise is going to be there.

That gauge and all of the other mods will not prolong the life of your engine as much as your driving habits will.

I should have added: the gauge allows you to adapt your driving habits to prolong engine life. It really comes in handy when you climbing over passes. When there is something is giving you objective information to drive 45 because your approaching maximum engine temperature your more likely to change your behaviors.

You guys using the gauze and oil air filters, if you run your hand around the inside of the filter tube every once in a while it'll show you how much dirt and grit gets through the filter and sucked into the engine. You'll feel it with your fingers.
