Well in that case could someone please explain to me how to set the cams/crank up correctly and install the timing belt seeing as I fked it up the first time!

how would it be the cams/timing belt? as i was very much under the impression that a 4age is a non-interference engine?
so in essence you could have the cams 180 degrees out of phase and it should still turn over?
Ugh.
Piston 1 at TDC.
Cams so inlet has just closed and exhaust will be next to open.
line up timing marks.
Cam gears only go on in one position.
put on belt.
....engine rotates clockwise.
I'm sure someone can give you a much more detailed explanation, i'm tired as fuck.

actually the cam gears will go on in two positions I fucked that up on my motor when I put the head on
make sure that the lobes on the cams are pointing to their respective manifolds
also is it possible that something found its way into the cylinder/s and is sitting under a valve?
did you have the plugs out at all?

Well, in theory they are, but process of elimination has basically brought it down to that.
Unless you've installed something horribly wrong, but considering all you did was the timing belt i can't see what else it would be.
Hey guys, I've found the real problem now. 86 Nick - I only had the plugs out after tit already wouldn't turn over, as I was told it would turn over easier with them out. They were only out for maybe half an hour at a time, about 3 times now over the last few days.
Heres the updated I posted on toymods:
Ok i took the crank bolt and pulley off, then removed the timing belt, this made it a little easier to turn but it still got stuck at the same points. When it got to these points it wasnt a dead hit it was sort of grinding. Someone on another forum said it sounded like I wasn't putting enough oil in the bores. Now comes the interesting part.
When I put oil in the bores the first time, I used a full syringe of clean oil, and divided it equally into each cylinder, through the spark plug hole. I decided to add the same amount the second time (15 mins ago), this time when I tried turning it over, when the the second piston (from the front) got to TDC, a heap of dirty shit came spilling out. So I used the syringe and got as much out as I could. I got about 2 syringes full of the stuff, before I had to start adding more clean oil to get it up high enough to be able to suck out the dirty stuff. I probably did this another 4 - 5 times and there is still more to go. Heres some pics to show what was in there.
This is the first lot I pulled out.
And to compare with clean oil so you know its not the camera darkness.
After diluting it and sucking it out for a while I can now turn the engine over, however, I want to know what this shit is, why its in there/how it got there, and what it tells me about the condition of the engine, seeing as I payed almost $800 for it on the basis that it was a low km(60,000ks) clean engine, when I could have got a 150~k engine for half the price.
Not happy jan.
its really hard to believe any importer that sells a 20 year old engine on the basis that its only done 60,000 kms, really you should take it back and ask for a refund or another motor.
From what you have said, it sounds very much like the motor has gummed up. there are other, worst case senarios also.
Could also be from being stored or transported in an other than upright position i think.
drain the oil from the sump, get several litres of diesel and put that through the motor with the sump plug on, pour it into the bores with the spark plugs out also, let it soak for a bit, then turn the motor over, try and free it up a bit and when/if it does keep turning it over for a while, then drain the sump again and use compressed air and a air gun to blow all the bores free and dry. Diesel is oil based so no need to worry about that.
then put clean oil in it, new plugs and see how it goes then if it all free's up `
so did you remove the plugs, fill the cylinders with a syringe full of oil then refit the plugs?
if you did that then you would have been hydraulically locking the engine, hense the reason it wouldn't turn over....you can't have that much fluid in the cylinder and expect the engine to turn over.
a full syringe is WAY to much. you should have used a quarter of that
