What's y'all opinion on rebuilding a 5.4 or buying a rebuild? Bocephus has 180k on him and is feeling worn out, and one of these will be in my future. Thanks

Bocephus lol. Give him a little more credit, he needs some updates that's all. They do get tired at about 180/185,000 miles. Tell you what tho, update the O2's, PCV, Injectors, coils and plugs and he'll ****ten and grinnen (in a positive way of course)...

Not kidding, - mine felt like a slug at 185,000 miles, so I decided to go thru it in that way. It went from heavy feeling slug to a light feeling, quick/responsive truck again. Believe it or not, runs better than new and it's @ 309,000 miles now. They are great engines as long as they are not too abused. On the other hand, they are very resilient and can handle a little neglect from time to time.

IMO, - never go with a reman and definitely don't rebuild, (unless it's more of a hobby). Been around these long enough to know your best bet is getting a low mileage used engine.

Far to many remans fail prematurely (even the Jasper remans) and rebuilding is time and money.

Thankyou [MENTION=113]Jbrew[/MENTION] , I see in your sig something about type 3 injectors, what are they?

Id like to know your opinion on the injectors as well Jbrew. Sorry for the off topic, but I was thinking of doing injectors next on mine after I install my E-fans & underdrive pulleys. I still need to do a plug swap & at the same time I am planning on all new coils as I have no idea if this truck has even had a plug change at 160K now. Ive heard some people say larger injectors are a waste unless your running forced injection. Did you notice much by upgrading?

Jbrew

Bosch Design 3's have the better spray pattern compared to the short fat factory injectors. They are a bit louder tho. Nothing big as far as mileage or performance difference,- that I noticed anyway. Hard to say really, I went thru the 98 and replaced everything in one weekend.



Larger injectors won't help anything. If your close to 300HP then yes.

Now you can run larger injectors, - but why lol.

Yea here's the table, at the bottom, -

Here's how you service what you have,-

Yea, one other notation.

Injectors have two types of connectors for EV1 and EV6 type injectors. Make sure you match injectors to your harness. Think I have a pic of the difference; Yea, -



In that pic ^^ I found injectors from the Romeo plant, -new takeoffs from a 4six Crown Vic crate. I asked for the harness as well. Many times I have pillaged that harness to replace a connector that was broken lol.

So yea, just keep that in mind when purchasing injectors. All ford connectors are replaceable. There's a PDF catalog online.
