Salvage engine questions

I'm going to need to buy either a salvage or rebuilt Zetec engine for my ZX3, due to the one that's in it being totally screwed up and not worth fixing. Has anyone here bought an engine from a salvage yard before? Are there any differences in any parts of the Zetec through the model years? I don't want to buy one off an '03, for example, then go to put it in only to find out all of the wiring harnesses have been changed.

How do they sell it, is it on the ground or running and in the car? I'm not buying any engine unless I can do a compression test on it, and that would be kind of hard if it's laying on the ground. If I hand cranked it with a ratchet, that should still give a valid compression reading, right? Won't having an (iron) engine laying around outside cause all of the coolant passages to completely rust out?

Really my main concerns here are compression and rust. I don't want to buy an engine that's the same or in worse state than the one that's already in the car.

Protip: NEVER buy a used car without doing a compression test on it. Ask me how I know. What a piece of shit!

Obviously it should be much easier to install a motor of the same model year. Several years ago I had to replace the motor in my '05 ST, and was fortunate enough to find one only 300 miles away. It was in a big yard, still in the car, and sold to me with a 90 day warranty. I got a photo copy of the title certificate from the donor vehicle, for proof of origin of the "non-matching" motor's serial number. Because it was the same model year, installation was "plug and play". There should be many '00 Zetec motors around, although condition will be an issue, it will take some time to hunt one down. You might even find one in the classified section here, or on FJ. Good luck.

Their is not enough difference to worry about. If its a newer year you may need to swap injector harness (one has a square plug and one a rectangular plug going to the ecu depending on the year). Also make sure it has the proper cps before you install it ( the manual trans. takes different sensor then an auto trans.) The newer year cruise cable has a different end on it then the 2000 and 200l years (you can swap your throttle body over or change the cable to the new style)

Crankshaft position sensor? I can just swap that off my engine to the new one, right? Are there any other mechanical differences between manual and auto trans engines?

NEVERMIND!



Protip: Make sure that your compression gauge is accurate, and that whoever is using it takes their damn time to make sure they select the proper adapter for the spark plug hole so it actually threads in and seals properly . I thought I had to do an engine swap! I did the test again today, except this time it was me who used the gauge. I got 149 PSI across the board, and leak down was 5-7% @ 100 PSI. Both tests were done on a cold engine. I think it's safe to say I don't need to do an engine swap!

Well, that was awkward. Carry on gents.

OOPS!

I was thinking of someone else looking at a junkyard engine.

(kicking my butt)

Now I can not say for 100% certainty on a Focus but when I have dealt with engine swaps on Contours the year of the engine itself didn't really matter. This is mainly for the Duratec but should also apply to the Zetec ... we always used the harness and fuel injectors/rail off the car the swap was being performed on, this included the assessories and sensors. The engine is mechanical and doesn't care what electronics, etc run it.

Now with what I know about the Zetec having VCT versus not having it, the year of the engine would make a difference.
