One of the intake cam sprockets on a used motor I purchased had a crack where the dowel pin goes. I decided to find a used one and bought one off of here from a forum member. got the Cam sprocket in, although it has a lot of oil staining on it, I figured it should work. My question is, are these 2 sprockets interchangable? the clean one is the type that came with the motor and the brown one is the one I got. The brown one has allen head screws on the cam side. just want to make sure I can have one with allen heads on one intake cam and the other type on the other cam. I really don't want to have to pay 300+ for a new cam. I checked sewellparts.com and the part number is the same for all year g35. any input would be appreciated, would like to seal her up soon!

The brown stained one with the allen screws is from an early version VQ.
Clean it up with an aerosol spray carburettor cleaner & count the the # of teeth on to see if they are the same & that the chain position markings are in the same place on both sprockets relative to the dowel pin.
Also check that the position of the oil holes is the same.
I have assembled many VQ motors & from memory they all had the allen screws but none of them were rev ups.
I would also remove the front plate & clean out the inside as there could be gunk & varnish in there.
It's very simple to do & there is nothing fly out. There is only 1 spring with a small blue plastic cap that locks the unit together on crank start before oil pressure lifts it of its seat allowing rotation.

It looks like they're all the same, or at least interchangeable. Part number 13025 is used on all versions shown.

The one with the allen screws weighed in at 60 oz, the newer version weighed 58 oz. Not that big of a difference.

MREDDLE

I figured there would be more of a difference, O well. Thank You for taking the time.

I just finished a rebuild of my VQ35DE and it won't hit a lick. Got fuel and fire, but no love. My concern is that during the rebuild, I accidentally dropped one of the intake cam sprockets and according to the service manual, you should avoid any shock to these when handling. Any ideas would be greatly appreciated.

Thanks!

I assume "won't hit a lick" means the motor won't start.
If you have injector pulse, spark at the plug, fuel pressure in the rail, then the next thing to check is compression in the cylinder. If all these are OK the next thing to check is ignition & valve timing.
It's highly unlikely to be a dropped sprocket more likely incorrect timing chain alignment.
It is also possible to fit the flywheel in the incorrect position & this will effect ignition timing.
So 1st check compression
