Like the topic seas, I did a timing belt and waterpump replacement about 2k ago and installed some skunk2 adjustable cam gears along with it and the other day I took the car out, stoped at a light and about a minute later took off again easing it in from first to second and taking second up to 4k the car just seemed like it chocked itself out so I got off the throttle and it died on me...

Yesterday I pulled the valve cover off and look at my cam gears but they are still zeroed out so I turn the crank pulley to top dead center and here is what I found:

At top dead center the exhaust cam was at top dead center the intake cam was sitting 90 degrees advanced, so I took off the cam gears and found that the shear key on the intake cam didn't completely brake off but shifted and damidged the key some...

How could this have happened is what I want to know so this doesn't happen again.

must of been a weak one or either that, it might of been too small to fit in the gap and had alot of play. You should find a nice thick one that you'll need to tap that sucker into the hole with a hammer.

 

Not sure about this, but it may be harder on the keys when you have stronger valve springs. We bend them up in our race motors every few months but replace them before distort.
Be sure to check for bent valves in the side that broke by doing a compression check. You'll be lucky if nothing broke.

Earl,

My head is completely stock so it couldn't have been the springs but I also performed a compession check and on a cold motor the compression was ranging anywhere from 130psi to 135psi across the board...

So I'm kinda lucky with that....
I hope this doesn't happen again and I think I'm gona switch back to stock cam gears because those skunk units are just plain trouble...

Adi

 

Maybe you got lucky
Yeah, I suppose the problem could be with the design of the cam gear itself. Doesn't seem like that should have happend to a stock block set-up.

 

Sure as hell hope not..I'm getting Skunk2 cams, gears, valve springs, and retainers next Monday..

 

If I was you I would stay away from those skank2 cam gears and go get some toda or spoon sport units.

The second day after I got my car all together and turbocharged I took it out and gave to give my friend a ride in it, so I get on it and the car just dies so basicly just like the scenario up in the fist post...

It ended up being that one of the cam gears slipped...
My friend had the same thing happen in his jdm gsr civic so basicly the bottom line is you get what you pay for!!!!
