Hi guys I have a 05 Range Rover with a M62 engine that I had to retime because of replacing chain guides. I have installed everything back so far except for valve covers. But before finishing up I have 2 questions for any of those who may have done this job.

1) I used timing kit cam lock blocks and flywheel pin to time everything. Intake cam pins showed continuity and I tightened everything up. But when I remove cam blocks, passenger side intake cam shifts out of position while driver side does not. However if I manually retard bank1 intake cam with a wrench to fit cam block back on I get continuity. Is that ok or is it out of time and have to be redone?

2) I have read about the Vanos bolt or timing wheel nut coming loose on its own after bieng removed and reinstalled. How often does that happen? I tourqued the cam bolt an extra 15lbf for 96lbf and the nut an extra 5 lbf for 35lbf. Think that would be ok or should I take it apart again and use loctite?

1. That is normal for the passenger side cam to spring back slightly into its place.
2. I have not ran into any issue reusing mine. But it is always safe to use new bolts when doing that kind of work.

Cool thank you very much I鈥檓 going to finish up valve covers now then. The workshop service manual mentions needing a new bolt for the crank because it鈥檚 a torque to yield bolt but didn鈥檛 mention the same for the cams so I figured it would be ok to reuse the old one. Thanks again. I鈥檝e got my fingers crossed.

1. Absolutely normal, what's important is when you retard bank 1 fully, that the cam blocks then should slide right over it.

2. We replaced all 4 bolts, plus the impulse wheels and locking nut and initially locktited everything, but after having to redo the job 4 times due to mistakes on our part, we didn't put any locktite back on. I think what's most important to do is clean out all the grease and oil from those thread holes which might act like the reverse of locktite.

Taking it apart up to the upper timing case covers, retiming it and putting it back together should take about 4-6 hours, which imo isn't too much hassle to do the job correctly for peace of mind. I would take those bolts out, clean out the holes real good with carb or brake cleaner and then locktite everything, but be careful not to get locktite in the VANOS transmission oil holes when inserting the bolt back through.
