5.8 Overhaul
Hey guys, I decided to start a new thread as my motor, tranny and transfer case are now out. Truck is a 1993 F-250HD with only 104,000 miles, automatic with four wheel drive. This is my plow truck for my driveway. It has never said no in the short time I have owned it (bought it last November). She deserves to be refreshed!
I originally intended to only pull the motor as my spark plugs rusted and broke inside the heads, but when I was under the truck wrestling with the bell housing bolts with minimal success, I decided to pull it all in one shot and I am very glad I did!
Just about every emmissions pipe on the truck was rusted out and broke, spark plugs were ready to fall off or could not come out, rear main seal was leaking, two intake bolts were loose, intake gasket was leaking fuel/air mixture, vacuum lines were cracking. Anyway, you get the point, 104,000 miles or not, it was time for an overhaul and the only way to do it right is by having it all out in front of you!

Engine, tranny and transfer case came out in one shot. Once the engine itself cleared the hood latch area, I had to re-position the hoist. I did this by placing the engine on the radiator support with a 4x4 underneath the engine balancing the weight while two friends held it in place. I was then able to re-position the chains and hoist. It went smooth with no problems.

So much rust!!
Wow, that engine really needed to be pulled to do all that needs to be done. I have a '92 f150, 5.8L with 155,000 miles and it is rust free both in the engine bay and the frame/body. It makes me glad that they use very little deicer on the highways here in Oregon. I assume there is a lot of salt on the winter roads in NY which accounts for all that rust.
Good luck on the rebuild. It will be interesting to follow your progress.

Thanks guys. yes two of the mount holes were already broken and it appears whoever rebuilt the tranny and transfer case use JB Weld to keep a piece on top ofthe mounting holes. It actually held good, but I re-cracked it when I was underneath trying to wrestle/heat the bolts.

I am going to change the heads out for Gt-40's, have the motor refreshed, get a new oil pan, maybe a gt-40 intake and a bunch of other new parts. A benefit was that the tranny and transfer case were completely rebuilt. I didn't know that when I bought the truck, bonus! I am really looking forward to doing this. I just love bringing things back to life!

Doing the same thing here right now too, well almost. Started out replacing the core support. Figured I'd do the MAF wiring and such at the same time cuz it was only a couple more bolts to get the fender completely out of the way. Well, while I was there it would be a good time to tackle the firewall water leak, so why not. Meanwhile, I found a set of gt40's with the thermactor holes, YEA. Found a few oil leaks, (pan and valve covers). Already this far, might as well pull it. WOW look how easy it will be to change the spring/shock towers now and repaint the frame. Needless to say it'll be a while 'fore she sees the road again. "Honey, it'll be great, give me something to do in my SPARE TIME." ROTFLMFAO
