Dyno. Compression test.

a compression test will tell if it is going to be a good strong motor, but there is no way to be sure of if there is any faulty parts.

Rebuild it yourself with proper parts.

[mad082]

even if you build it yourself with proper parts there is always a small chance one of the parts you put in might have a weak spot, or a fault you can't see. it is just something that can happen, no matter how much you spend. not much you can do about it.

check the spark plugs, probably the easiest test u can do in the garage. if their black, get ur car some nicorette patches.

Leak down test? It's like a compression test, but with more depth to fault finding.

Have a mechanic check over it. They know stuff about cars and shit, heh heh.

As for faulty parts, well, you get what you pay for. Part companies with a good reputation probably didn't get them by accident. I'm sure that reputable companies utilize technology such as ultrasound and x-ray to see where you can't, before selling you the product.

And cars are like chicks, cost money.

Edit:-

BTW what are you planing to do? If you are upgrading the bolt-on bits, then I would definalty go and talk to a mechanic as a lot of money spent on the inside of you engine might be a set back, but might give you less heart ache in the end.
