VQ37vhr timing chain

Once those are set you couldn't just have one cam be off you would have to have both intake and exhaust be out of time. So with that said yes you could get the engine back to tdc, remove the primary chain and then re time the engine. If the intake and exhaust cams are in alignment and the primary chain aligns the intaks to the crank then that means your exhaust will be in alignment as well. Hopefully that makes sense, I've not done this particular engine but it's no different in design that others excepte for if the vvel gets screwed.
