On some belts markings do line up 1/2 and 3/4, others the markings bear no relation to cam positions, others have no markings. Long as crank locked, cams in correct alignment and tensioner correct, should all be ok.  Thats why engine rotated a couple of revs and settings checked to ensure correct timing

Seems a Vx V6 thing

fair enough. whoever put markings on them that didn't line up with where theyre supposed to go is a bit insane

My genuine belt had no markings at all on it fwiw

Not helped by me fitting it though

If the crank lock is in place, and the cams line up with the horseshoe tool with the cam wedges out and the tensioner correctly set, thats right.

Turn the crank over 720 degrees (by hand) and check again, adjust if required and repeat, until no further tweaking is needed.

Do all engines need a crank locking tool

Do all engines need a crank locking tool 

No,some makes have no provision for one and rely on marks

The Nissan (VG30DETT) was like that - a nightmare trying to hold all the sprockets in place, let alone rotate them against the valve springs when they inevitably snap to their 'resting spot'..

Hi All,

Just to finish off pictures of belt in situ timing done 

needed to be adjusted on first 360° rotation of cams, then tensioner checked, 2nd 360° rotation spot on marks and same for 3rd 360°. Torqued up to specification, one happy bunny 


Gauge on cams 1 & 2


Gauge on cams 3 & 4


Crank lock on & snug to water pump

Thank you all for your help about the belt markings, etc. Being an inexperienced mechanic when it comes to engines I was quite worried that I'd done something wrong 

Would an Admin consider putting an addendum in the Timing belt Guide in relation to belt markings not necessarily lining up with the marks on all or any of the cams as per

It would have save me a lot of worry and would save others having to ask the same type of question in the future?
