How to cut the valve cover for cam gears?
You can use either a hole saw (for the crecent moon look) or a dremel (to take off the whole side of the valve cover, better in my opionion). I'm sure there are a thousand other ways, these are just two of the most common.
RStoR did his on a drill press, looked very, very nice.
I've seen Willard cut a few with a Dremel, my own included. Take your time, be patient, and you'll get good results. Oh, have a good stack of cutting wheels on hand.

Care to elaborate?
Seems as if Mr. NZ has two valve covers. One he would like to cut for tuning purposes, one to keep stock. How is this a bad idea?

Not the way he wants to do it, if I read his post right; He says he has 2 valve covers, 1 he will cut and put on the car at the dyno to tune, and another un-cut that will be on the car while driving around...sounds like a good plan to me
Edit *damnit splat*

If you have 2 valve covers, why not just cut off the left side of the cover all together in the one that will be used for tunning...no need for round cuts or anything...

Yes, there's a risk. How big the risk is up for debate.
All kind of things are flying around on the road. Would you like to have a piece of gravel or debris fly in and get lodged between your timing belt and cam gear? For the people running a lower belt cover, but no upper, it will probably fall down into the bottom and get bounced back up into the belt with each bump.
I'm not saying it will happen... just that it could.

Theoretically, road debris could find its way in and trash the timing belt. But I've never seen or heard of that actually happening. Not saying it couldn't happen, but I haven't seen it.
I think your plan is right on - one cut for ease of tuning on the dyno, one uncut for daily-driving bling. That's what I did.
PS - not sure if this is still the case, but back in the day, red C5 covers were by far the cheapest from Honda/Acura. C1's were almost double.

yes thats my motor!!!
haha.
there is a big risk. i ran open gears lke that, no cover on the timing belt. real bad idea when i went to the beach. i am in the process of switching the allen bolts to SS ones. they are $1 a peice at ACE
but i beleive if you MUST cut the cover, do moon cuts, and make sure the covers are on there.
i have a lower cover on there now.

A small bird could also fly into your brake duct and get sucked into your IM causing an increase in the popularity of disco, and blow your motor.

With that said, anything can happen. If we were all scared of the unknown, no one would ever leave the house.
The cleanest cut is done on a cut off style bandsaw.
Any machine shop can do it, and probably for less than $20.

I think I have a better chance of hitting something on the road and denting the oil pan, than I have of some road debris claim all the way up there and falling into the timing belt. For one, the belt is always moving and stuff tends to get bounced off rather than sucked in. I have had this cover like that for close to 2 years.

ive had mine open like that on both cars ive owned, and never had a problem. I need to cut my new valve cover, but i got a bling paint job on it and am going to have to be really carefull not to mess it up
It's definitely a possibility to get debris in there. I've had road debris destroy my power steering belt on the freeway, so after tuning your car, take the cut valve cover off and throw the stock one back on to be on the safe side
If you've got steady hands and perhaps a vice, then go for it. Also, we drilled two circular holes on the edges, used a ruler and a sharpie to make a pattern on the cover and then used a sizz wheel to chop it off. If I can find pictures, I'll get it up.
The same people that said not to run around with a cut one is the same people that told me to put a filter on my ITBs. Which I drove to bumblefuck and back without any problems.
You'll soon learn that a good percentage of the members on this board is a bunch of **** folks that really sit around and figure out all the possibilities that could happen. It's like hitting the lotto, you got so many possibilities but does it happen? Make like nike and just do it, but use common judgement.
I drove my car through rain, snow, hail storm, dust...you name it, I've been through it because it's my daily driver. Still nice and new when I pulled the motor out to sell. No filters on the itbs and a cut valve cover.
Found it...
