Engines what to look for..

[leeroy_25]

I have had a look through threads and not found all my answers.. maybe this could be a sticky one?

1.What are key things to look for when buying a second hand RX-7 3rd Gen?
2. My main concern is the engine.. How do you do a compression test? Is this with a standard piston engine tester? and what should it be?
3. Is a good second hand engine a good idea if it checks out and are they saleable?
4. are there any tell tale signs for bad things about to happen\'?!

Thank you
