Thanks very much mate
That is very interesting and seems he could be onto something.
Do we 100% know if the 4A-GE cam gears operate in the same way to the 3S-GE ones though? Makes sense if the 4A-GE has a spring to return it and Tosh explained there being a spring in the 3S-GE one too.
If so then mine definitely doesn't return on a spring when moving the camshaft by spanner (with the belt on) and I can definitely turn it backwards by the same amount after I have turned it forwards. Would still feel happier if anyone with a healthy engine could 100% confirm that there's is different before i buy any parts though.
Also wondering if I can test the solenoids as the diagram on that last page I posted up seems to show them supplying a feed to it to test it.
Tosh - Was it the intake cam gear or the exhaust cam gear that you had apart? Just to double check
How much did it differ to the one in the 2JZ / 1JZ rebuilding video please? (https://www.youtube.com/watch?v=1KQGRulDJSk
) Was it pretty much the same but with a spring in there?
Mike - Did you say there were some pictures of the insides of the Altezza one somewhere? Couldnt find them but probably missed it in all the text

I have got the whole manual and wiring diagrams, which a member on here sent me. i have PMed him to ask if I can share them on. They had been scanned in from the original and only a couple of pages missing that I noticed so far
Also they were in reverse order so I painstakingly moved the pages into the right order for the first 210 pages (the manual not the wiring diarams bit)
If you can read Russian, can you translate the gist of the procedure in those few pages please to see what they are doing/testing on the VVTi system and which bits are exhaust and which are intake please?
As an extra double check, I had the intake manifold and throttle body off yesterday to check that. The only thing that seemed odd was that when I turned the throttle wheel fully open (where the cable would attach), the butterfly only seemed to go half open but it felt fine so I presumed that either the potentiometer or the other electrical plug onto it worked something inside when its connected up with engine on and ECU telling it to and then would allow full throttle to open the butterfly. So presumed this is normal?
Will give the whole thing a clean out (apparently its normal for the Altezza intake to collect oil from what the boys on the NZ forum said) and put it back on at the weekend.
