V Spec Cams -

[oscar32]

Ok tech people. I've bought some second hand Vspec Cams for an RB26DETT from here, and have been told by my workshop they are stuffed.

The little half moon inside the end of the cam has broken off (partly)

The way my mechanic explained it is that the gears themselves won't hold the cam as there is too much of the gear missing from inside.

The guy I bought them from told me it was broken, but also told me they are still usable and explained this:

i had explained to you before you bought the cams that the half moon inside the end of the intake cam had snapped off. THIS DOES NOT MAKE THE CAMS UNUSABLE! It simply means that you need to align the CAS and the end of the cam up by eye. you can see where the half moon has snapped off in the cam. look into the CAS to see which way it is supposed to go, rotate the shaft that comes out of the cas so that it is the correct way. and there you go.

I'll get some pics up. Does anyone know what I'm talking about?? Any advice would be great as I'm sitting around with a car off the road and two different stories

Hmmm, a few point spring to mind:

1. The crank angle sensor is driven off the exhaust cam, not the intake cam.

2. AFAIK there is no difference between an R32 cam for a stock GT-R & and a V-Spec.

3. For the price of a cam & the amount of mucking around you SHOULD be doing in re shimming them - why install a busted camshaft?
