Thanks guys, I will try this tonight.
My only worry will be setting the timing up once I've managed to turn the inlet cam.
Say I manage to get the inlet cam so the notches are vertical. Then I will need to rotate the engine at the crankshaft again so that both the crankshaft and exhaust camshaft are at TDC again before refitting tensioner and chain. Will this not push the inlet cam I've set at TDC out of timing again? Will the notches being vertical mean that the inlet cam is at TDC on cylinder 1, in timing with the other shafts? Surely the notches will be vertical twice for every rotation, potentially I could set the crank and exhaust camshaft at TDC, and the inlet with the notches vertical, but its not correctly timed?
on a side note, I had my mate with me yesterday so tried to loosen the adjustor off whilst I had someone to hold the bit in the adjustor. I took the inlet cam notch out of the tool and inserted it so it was just holding the exhaust cam. Then my mate held the bit in the adjustor whilst I tried to pull it.
Unfortunately it has bent one of the bolts that secures the cam locking tool into the cylinder head. I think I will just need to replace the bolt with a similar bolt so not that big of a deal. I think it bent because I didn't have the other notch installed pushing against the inlet cam.
I think I could just use one of the valve cover bolts, and then replace it later?
