What to look for in a new/ used motor?
Wondering if anyone had any advice when sourcing a replacement motor?
Are there any telltale signs of abuse?
What else can be done besides a compression test?
Please advise

Aside from checking the various codes to make sure you're actually getting what you're paying for, there's no way to tell if the motor is in good condition internally or not if it's not in the car. Unless you crack open the motor. All the more reason to buy from a trustworthy place or person....

I deal only with Altech for my motor/transmission work..
They got me my motor which was in mint shape but the tranny had syncros gone like mad, so for a decent price they arranged for me to get an LSD tranny that would fit my B series motor.
The rest is history.

Go ahead and email them if you have ANY questions, Joe will be glad to take care of you.

Leakdown test will tell you whether the valves (dry test) are closing up properly or not. It will also give you an idea of what condition the piston rings (wet test) are in.
Compression test will give you an indication of how well the piston rings are holding up, although carbon deposits on the top of the piston may throw off readings slightly.
The readings should not vary by over 5%, otherwise you have a little problem on your hands.
Only downside to this test is that you need to have the transmission bolted on to the engine in order to turn it over.

bring a compression tester with you when you buy it, hook it up on the floor with a battery and check compression before you buy it, a friend of mine bought a b16a and brought it home and there was only 45 lbs of pressure in all cylinders, fucked.
