Hey!
I had engine rebuild and now i try to adjust timing.1st I set piston TDC and then i lock camshafts.Then I install Intake VVT and chain then.I turn Intake VVT to the right until it stops(if u face it from transmission side) and then I turn exhaust vvt to the right and install it with chain to the camshaft.Everything is okay.Cranck is TDC ,camshafts are okay and VVT marks has 16 roller links.Now if I turn engine 2 times and stop at TDC ,camshafts and VVT are messed up :S .What am i doing wrong?

Is the chain correctly tensioned?

 

[Kahvel]

Yes.

 

[Steff]

How far out is it after turning the crank twice?

 

[CorradoR32]

The timing marks align every 4 crank turns.

As above, cam timing is every 4 turns of the crank, not 2

This confused me at first, I even re checked/re timed the chains again just to be sure. I just put it down to the marks were there as a guide to the initial timing, not every rotation.
Might be worth adding this bit of info to the DIY thread ?

The crank and intermediate marks should definitely realign every 4 turns though (cams run at half crank speed). That applies to every 4 stroke engine, not just the R32

The VVT markers might shift a little and you're right, the copper coloured links are to aid initial alignment and won't realign. Once the VVTs are filled with oil, things move again. Hence why you never see 0 and 0 in blocks 208 and 209. It's always -3, -2 or -1 sometimes -4.

or -6

Make sure she. U put tension rails back on that the timing marks stay aligned this can cause unalignment aswell mate happened to me before

if this helps mate
