    They show up on eBay pretty often.. but I'm with the other commenter... the little flag tool works just as well or better. It's a simple go/no go that fits into a small hole in the surface of the head and spin it to just clear the top of the injector. The real hard thing is to determine when the injector is at the absolute bottom of it's travel. You'll see when you bar the engine over, there are NO indexing marks and you're eyeballing the injector plunger as it goes down... catching it at absolute bottom is the key. For me, the little flag too is easier to use.

    The injectors are set when in their relaxed or closed positions, with exhaust valves fully open.The exhaust valves are set in their relaxed or closed positions, with injectors fully open.It is simple to hand crank to these positions as the injector and exhaust lobes on the cam are practically 180 degrees from each other... https://m.youtube.com/watch?v=pJkGg7Mqrs4

    The dial indicator on the Snap-On is a sure way to make sure of the cam position.

    Thanks for the link, but I purchased the one posted earlier in this thread.

    Just finished the tuneup procedure and I will say without a doubt this tool was worth it's weight in gold and well worth the $400 I paid for it. It made setting the injector heights a breeze and without a doubt FAR more accurate and consistent results than the pin tool or any other method.

    Anybody thinking of tackling a tuneup themselves I HIGHLY recommend springing for this tool (and the other specialty wrenches/tools...etc). You are saving thousands by doing it yourself, may as well have the best equipment to do it.

    After tackling this I feel VERY comfortable now pulling/replacing injectors and repairing anything else involved in the tuneup procedure.
