How did this guy do this, I need to know

[dsmoverboosted]

I am going to be changing my valve seals soon and I found this pic of a guy doing it with the cam gears still in place and i wanna know exactly what it would take to do this. The zip ties holding the timing belt in place is pretty easy to see but what could i do to keep the cam gears from falling after i remove the cams? What if the air i use to keep the valves from falling pushes down on the pistons?

I am very interested in not removing and reinstalling the timing belt if i don't have to.

Thanks

zip tie the timing belt to the cam gears. then use a large wrench to hold the cam in place (Take off your valve cover and youll see the place to put a wrench to hold the cam, and then use another wrench to break the cam gear loose.

So the cam gear will just sit like that after the cam is removed? What about if the pistons move when I add compressed air, should i just be carefull about how the gears move with the pistons?

Well it appears this guy has bungy cords attached to each cam gear probably hooked to the hood to hold them in place. The air that you use to hold the vavles in place should be low pressure and should not be a problem.

I am sooooooo happy I found this picture, this is going to save me soooooo much time . I guess I doesn't really matter how the gears rest as long as the timing belt is tightly zip tied so it will be on the same exact tooth when I reinstall it. I guess If i decided to use rope instead of compressed air to hold the valves in I could just have someone help me by turning the gears while I turn the crank.

*EDIT* Well I guess I have to use air now that I think of it because The zip ties holding the timing belt on would limit how much I could turn the cam gears. Great news none the less.
