Hello blue ovalers, I'm looking at picking up a used 92-97 F Series sometime soon, and I'm not going to ask "what engine is best" because I know there's no right answer. I've read a lot about them and know that they're all very reliable and all that, but something I haven't really been able to get a good idea of is how easy they are to work on. I currently have a 1990 4.9L, and frankly the only good thing about it is how much room there is in the engine bay and how easily accessible most things are. I'm wanting to get 2 extra cylinders, and between the 5.0, 5.8, and 7.5, I'd like to know if there's any that a regular guy with a set of hand tools should stay away from. One of the biggest deterrents for me for a diesel for example is the huge time sink even simple repairs can be, due mostly to just how cramped and poorly organized the engine bays are. I've replaced quite a number of parts on my current truck just standing in the engine bay with some basic tools, and more than hp or towing capability or anything else, keeping that level of repairability is most important to me, so I wonder if any of the 3 engines I listed earlier are better or worse for that
Well, i have a 5.0 and as for major maintenance, 2 water pumps, couple caps and rotors, and a few sets of plugs in 155k ive put on it since i got it 11 years ago. Easy enough to work on.
The 7.3 is easier to work on in my opinion. The only part that's hard to get to is the up pipes. The 7.3 will outlast the truck if regular maintenance is done.
That all said, I agree with above about the 351w being the same effort wise as a 302 bit with more power. The big block sounds cool but parts aren't as easy to come by and aren't as cheap.
I wouldn't pass on a powerstroke diesel if you get a decent deal. The gas motors are great too
The 4.9L, 5.0L, 5.8L, and 7.5L are all good long lasting engines and relatively easy to work on (if you don't believe me try working on a 3v 5.4L in an 05-10 truck). The 5.0 and 5.8 are only a marginal improvement over the 4.9 in terms of power, so my vote goes to the 7.5L. It's everything the small blocks are and then some. Nobody is buying a 25+ year old pickup for gas mileage, so I didn't factor that in to my vote. That said, my 4.9 gets a whopping 14 while the 7.5L gets 11.
