R32 Gtr Broken Camshaft

[rev210]

thats what happens when you dont know what ya doing

you have to GRADULY wind down the bearing caps conmcentrating on the loaded areas. (lobes opening valves)

it should take about 10 mins max to do each one properly

10min each sounds about right for torquing them down.

The nissan sequence if the cams are correctly positioned , does just that as you are saying. I think you are quite right as when you see it all before the cams go in it just makes sense to do it that way. If you have the right kind of training and experience in engine building you can work it out without knowing the nissan manual sequence as long as you know the torque target on the bolts .

I didn't break mine, and I'm pretty sure I never would with a good set of new bolts. Re-used old ones is where you are gambling. If they are known to break it means they are really past it after 100,000kms or so. I managed to break an old one I tried to re-use and I have heard of others breaking some time after being re-installed, lesson learnt no harm no foul.
