It was in Texas, I'm in Michigan, the freight was high, but it was still under what that engine is worth if it was treated well. Couldn't do it, absolutely no history on it and no miles verification soo... If everything was normal about the motor, that price was a steel. Good luck finding an engine. If you find one with decent miles, expect to pay about 1300.
well there are a lot if junkyards around me. Raceway in savannah tn. Normally has pretty good deals. And miles don't bother me on a engine when buying from a junkyard cause you really never know what your getting anyways. I called a while back and they had one with 160,000 miles for 950 with a core. I'd be fine with that. Comes with some kinda warranty but can't remember what... As I always say once you buy one and drop it in... Give er hell and see is It gonna last lol that way if it don't the warranty will cover it. Most the time they give 30 days around here

Full syn has so much more cleaning capability, the skin falls off the walls and plugs the sump or pick-up screen. It collects and layers on the screen. The engine heats up begins to seize until you the connecting rod or rods break. She's cooked!
Well hopefully the PO used synthetic oil then. She doesn't burn Any oil and I have had it for almost 3 years. How long do you think it has

That's good and bad. Good you have the experience but bad that you've had to do it so often lol.

Sorry to hear about the motor man. But hey, you could always throw a cheap junk motor in it then build a motor with all forged internals and just have a strong NA motor to put in when its done.

Then you could sell the junk motor when you swap the built one in

Yea doesn't matter now. It's the initial shock, -they call it "shock". Like say shocking swimming pools sort of thing, -for lack of a better explanation, - or a shorter one anyway lol.
Strips and cleans and does it quickly, in a much shorter amount of time than your referring to. Yea, I realize I made it sound longer, but it happens quick "Shock" when switching to 100% full Synthetic without a flush first. Within iduno, 500 miles or so after shocked or shorter. Built up skin looses traction, falls off and heads right to the pick-up screen. Best you can do for these engines is just use Fords recommendation. This is for all F150's 97 - 03 or 2 valve engines. Use 5/20 Synthetic Blend. Stick with that and you can't go wrong.

Hope that clears it up a bit. The post that your thinking about I made, I referenced other reasons these engines can end up with catastrophic failure and wasn't as specific with defining each one.

Right, well first thing I do is check compresion. Since that basically tells all and you won't have to waste time installing it. This way is the best. lets face it, a bad engine can outlive a yards warranty. You can do this at the yard, but you can take more time testing it at home with various tests to get a better idea of engine health. It's a must for me lol, -it doesn't lie.

I agree with ya here.. Raceway does leak down test in them before they sale them. I trust raceway more than any other local yard. Right now I'm not sure what I'm looking to do just trying to get the truck back on the road soon. Motor I almost out now but a slight rain has ran my inside the house ! Lol how it's sitting right now.... Man what id give to have a shop. And to he honest every truck I've put a motor in that I owned I bought needing a motor lol. Except 1 of them and it was to many beers.... A mud hole.... And no rear drive shaft... Ahh good times.... Good times... Lol
