if you jiggle it you will feel there's a groove it goes into, I suggest you pull off the timing belt to get in into place

once it goes into place then hold the cam with a wrench and torque up the nut.. it will then sit flush and allow you to put the spring/cover/seal on

Because you have different cams I would not activate vct until you know you can. Cams with more overlap cant run vct or else the inlet and exhaust valves could hit.

Obviously you need to fix the leak though but dont plug in the solenoid until you are sure its ok.

      Alcon TA6 Calipers on R33 GTST - Flexing

      By Nismo32 · Posted

      Hello, The dog bone wont have much to do with this - the calliper applies a load about the disc - the outside of the calliper is more flexible than the inside by virtue of it not haveing the big torqued down bolts, additional metal structure on the caliper itself, and mostly not being cantilevered. So the outside of the calliper is pushing away as its more bendy and brining the inside with it as an equal pressure on both sides of the caliper looks to cause more flex on the outside - which makes sense. I have done this same thing with the calliper unbolted from the dog bone - same thing happens. Although id have to watch more carefully to see how much more the outside moves than the inside in this case. Im guessing there is a point in the pedals travel where the pressure is not actually increasing in the system - its just volumne displacemnt - and because the outside of the calliper is more flexy, it receives that volume. Have gone back to Alcon again - but beyond a resolution there I would stay clear of this calliper and possibly any of the lighweight type of callipers - especially if you have the smaller 15/16" master cylinder. Cheers.

      Yes, you can very clearly see from more than one angle that it is the whole caliper moving left-right, not deformation of the caliper. The top moves, the bottom moves. Equally. It should be possible to see where the movement is occurring. Just need to look more closely.

      Water pump replacement - Sydney region

      By billyons · Posted

      Hi Folks, my 2009 Skyline 370GT “Crossover” wagon is losing water and has been diagnosed as needing a water pump replacement (it’s an internal timing-chain driven unit, not the usual electric type that seems to be used across many manufacturers). Am looking for any repairer recommendations in the Sydney /Wollongong region who can be trusted and are experienced in this sort of work on the VQ 36 engine. Many thanks….Bill

      While all of the above makes sense, we're not talking about some Ling Long calipers of AliExpress; Alcon would have to be one of the top 5 caliper suppliers in the world and these are not their budget units. If there were manufacturing defects in the caliper causing this issue I'd be very disappointed. Having re-watched the video a few times I think it's dog bone/mount related. The caliper moves independently to the rest of the suspension and brake assembly which suggests to me that it's not mounted rigidly. I know this sounds stupid, but have you got enough thread on the retaining bolts or are they a poofteenth too long and it's not super tight? For axial movement to be occurring without deforming the caliper that can be the only answer.

      R34 GT+t stock Auto transmission?

      Extra torque will wear it out. The clutches won't be to the same spec as those on the turbo box, and the shift speeds possibly won't suit handling more torque either. Autos in R34s are a nightmare. 8HP conversion is the only sensible option.
