Im sooo freakin pissed...., need to let it out... Options

I bought a halftcut last yr (aug) and it had 3 months warranty on it. Done the compression test across 4 cylinders and they all good. So we did the auto to manual conversion. Popped the 3s in, had a bit of a problem with the rear mount but got that sorted out. Everything seems good ...

My mate finished the wiring and he fired her up yesterday, she idles good, revs good but he heard a knocking sound coming from the motor, he turned her off , took the intercooler out, took the camshaft cover out and by god.....he couldnt believe his eyes.

The camshafts arent toyotas, not aftermarket. Not even close, it looks like it made from some cheap doggy sh*t company, they're grinding against the cover and for some f*cking retarted reasons they installed backward.

We kinda know something was up with this engine, since we got it out we noticed the turbo has been sandblasted, the flywheel just changed and hasnt even seen its first 1000km yet, a few things here and there are just recently changed. It looks like the engine was kinda rebuilt (maybe just cosmetically rebuilt), at first I was kinda excited thinking to myself "WOOHOO I scored". Today, im pissed.

The thing is I cant claim warranty for the halftcut coz its been over 10 months since we started the conversions although we just started her up yesteday. I shouldda test run it when I first got it

Anyways will the camshafts installed backward harms the engine? We havenot yet run her on the road, as soon as my mate heard the knock he turned her off, the knocking could have been from cams grinding against the cover but who knows, could be more serious than that. I really hope changing the cams will fix everything up, I already spent too much money and time on this project..

Im just really sad and angry.

How are Cams installed backwards!? That's not even a question on how stupid someone can be, but how can cams PHYSICALLY be installed backwards on an engine that idles and revs fine. It's just unimaginable (and I have a pretty amazing imagination). I would like to know what kind of cams these are, because they almost sound magical .

You stated in your first post...
"The camshafts arent toyotas, not aftermarket." Well ok, so they aren't Toyotas, and they aren't aftermarket, then what does that leave us with? If the cams were grinding against the valve cover, then it's either not bolted down correctly, or you got some incredible grind with unbelieveable valve lift.

If in the occasion that these cams are so horribly wrong for the car (I wouldn't worry cause it's highly unlikely) then most likely bent valves. (but it shouldn't be, cause you checked compression before, and in order to do that, you had to turn the crank shaft manually, which would have bent the valves in the process, and the results would have been bad). I wouldn't worry, just take your exam and worry about the Celica after.
