| Is it possible? I have never done a timing belt or anything involving the cams or cam gears. I have read TONS of info on doing the procedure and am confident I know what needs to be done. The problem I am wondering about is after I set all the marks and am ready to remove the belt how do I keep the cams from rotating? I can't use a traditonal cam block because I'm removing the intake gears. If I line up the marks that should be TDC for cyl #1 right? Wouldn't that mean since the piston is at TDC if/when the cam does spin due to the valve spring pressure that it's likely to do damage by slamming the valves into the piston that's sitting at the top of its stroke? The only alternative I have read about is to pull the plenum and valve covers so you can get a wrench on the cam shaft itsself. I don't want to pull the plenum or valve covers. This is an absoutly last choice option as I just fixed a bunch of intake leaks. So how do you do it? What's the trick to changing the intake gears without pulling the plenum or smashing valves? The only other timing belt I have touched was on a ford contour, and both cams spun 1/4 turn when I removed the belt. I was so afraid I did damage I towed it to a mechanic and paid him $300 to put it back together.
