We went to look at a truck today, a 1995 powerstroke extended cab long bed 4x4 5 speed. When I test drove it, I did not hear the turbo at all, the truck seemed to have good acceleration, its my first experience with a 7.3 so Im not sure what to expect, but is it normal to not hear the turbo on these trucks or is it not spinning. there was no smoke the whole time. the truck started right up but has been sitting the last few months.
Thanks, my past experience is with the White Tiger which is a 94 351 almost identical to this one. looking to upgrade for a resto project any help would be appreciated
I used to have an '02 PowerStroke. If I recall correctly there was a water separator or something not far from the turbo. I don't know if those leak regularly, but they do open up, so that might be a possibility. Hopefully someone with more PowerStroke experience can chime in too.
as for the turbo while, I could often hear it in mine, but it was a complete dog until the turbo started building boost. If you didn't walk away from the test drive thinking that it was the slowest thing on 4 wheels, then the turbo is working.
It took a few days before I could hear my turbo through my bone stock exhaust and factory intake. But eventually I could...assuming you didn't go to too many Who concerts, you will too. I swapped the crap leaky factory air box for a large filter, a very common mod, and I could hear the turbo a little better. But it is still a song that I hear that the rest of the family either chooses not to hear, or refuses to be enlightened...their loss.
Sounds like the turbo whistle on these stock 7.3's just isn't very noticeable, which makes me feel better about this truck. Still concerned about the fuel leak but with research on the 7.3 forum on FTE it seems like its a somewhat common problem with these engines.
There's a few o-rings on top of the engine that dry out and go bad over the years. Some examples are the fuel bowl drain valve o-rings, fuel pressure regulator seals and the fuel pump itself leaking. There are also several rubber hoses, one in particular is on the bottom of the fuel bowl and is connected to the fuel pump. It's likely rotted and leaking.
As for the turbo whistle, if it has a stock air filter housing, you won't hear it. If you purchase the truck, you should replace that housing with a 6637 or equivalent filter to REMOVE the housing from the system. It is a poor design and allows dirt to enter the engine if it's damaged or hasn't been modified by TSB. Even after the TSB had been completed, it can still leak.
