Kinda looking at a 6.9 info please

[Gear Jammer]

Well i went yesterday and looked at a 1986 f-350 4x4 with the 6.9 in it and a 4speed. The truck only has 21,000 miles on it and the motor has less then 5,000.

Let me tell you alittle bit about the truck. It was the fire company's brush truck thats way it has low miles. Some yahoo try to cross a creek with it and sucked a water in the motor so thats way it was replaced. It has a 8ft wetsern plow on it and a big azz winch on the front. This truck is very very nice. No rust anywhere. It was garage kept its whole life. They just replaced it with a 08 f-450.

Well i dont know jack about the 6.9s. I have a 6.0 now and thats really all i know about. Are the 6.9 good motors do they have any major problems??? Give me some tips. If i can get this truck it will be just a beater truck to go back and 4th to work in and stuff like that. I will be keeping it stock and not doing any modding.

Thanks

Thats what i want to hear. I dont really care to much about power as long as it moves the truck lol. I want reliability.


Well they backed out on selling it. But they are going to bring it up at the next firehouse meeting. So im hoping they will be sellling it again. If i get it i will post pic. of it. It will be the cleanest 86 you have ever seen. I think it is cleaner then my 04 lol.

What these guys said. It will get the job done. Just dont expect anywhere near the power of your 6.0

6.9's are pretty decent motors. Their valve guide design causes them to burn a little oil, usually around 500 miles per quart is an accaptable range. They have 7/16" head bolts, and the factory head gaskets design isnt that great. If head gasket failure happens down the road, you can get ARP heastuds and new headgaskets, and you should be good. Other than that, they are pretty good at what they do.

If you turbo it, and turn the pump up...it will have more power than a stock OBS PSD, around the same, maybe less than a second gen 7.3, and more than a stock 12 valve cummins.

Keep up on maintaince, and they will last a long time. I know of a couple people with over 500,000 miles on their IDI's, one guy went 650,000 before it finally conked out.

Im glad to hear that the 6.9 is a good motor. The good thing about it is i will be bale to work on alot of stuff my self. Im just hoping at the next meeting they will sell it.

I was helping a buddy of mine load for our swap meet this weekend, They had a fire a few months back and his fathers land was hit hard, He has a 6.9L long bed single cab dually missing the tires, I saw it was a manual tranny and pretty clean inside. The hole truck was untouched by the fire and he has the title, I told my buddy to offer him $200 and I will haul it away, There is something that drew me to that truck. If he takes my offer I will be bothering you IDI guy's quit a bit.
