Hi from Pa buying 93 4wd pu that needs engine work!

Hi, I'm going to be a 93 toyota 4wd pick-up owner Monday.

Here is the story.

A buddy of mine has a 93 4wd pick up with 130,000 in pretty good shape. One day after work he started it and it was knocking and squealing out of the blue. He shut it off and had it towed to his house, it has been sitting there for two years, he never looked into what was wrong. He said it aways ran good, did not use any oil, just minor usual problems (starter,fuel pump both replaced).

I plan on buying it from him Monday for $500. What do you think the knocking and squealling noise is? I'm hoping it's just the bottom end bearings. If not I plan on getting a short or long block for in it worse case.
I will have a decent truck for $2000.

I'm no car mechanic, but I have changed engines in the past and I'm confident I can do this.
I have been doing research on remanufactured engines, anything special I should be looking for?
Any ideas or info on getting this truck on the road would be appreciated.

I started today and have it just about ready to come out. I think the worst was the wiring. Pulling all those wires though the intake manifold and the wiring that goes back to the tranny and transfer case. It should be a real pain getting them all back in and going to the right spot. Some went up, back, down, across, oh ya fun,fun,fun. Overall II think it went well. I did an online parts request for a engine and received about 7 responses. One is 55 miles away, 93,000 miles on it and a cost of $600.

I do have some questions and see photos below. Is this where I should disconect the fuel line (4th pic)? How do I get the 2 17mm bolts out of the upper bell housing right next to the firewall (2nd & 3rd pic)? I realy didn't try hard, I was done for the day and getting tired. I thought I read somewhere I might be better off taking out the tranny with the engine, is this true?
Picture 5 is what came out of the bottom of the radiator and some of the other low hoses, very oily and sludgy. When I removed the steel elbow that is conected with two hoses from the water pump to the bottom of the radiator, there was a thick oily sludge coming out of it.
What is you take on this cross mixing? Where did the oil and coolant get mixed at? Is it probably under the timing chain cover?
