Yesterday I was driving up a bridge when my car lost all power. When I looked into it my exhaust cam gear loosened up and advanced itself all the way. Here are some pics.

Head all unbolted and ready to look and see how bad the damage is (toda header blinging)



Here are a few shots with a light under the valves. You can see the light shining up through the bent valves




Here is one of a piston. Luckily none of the pistons were damaged. Just a minor mark on all 4 of them.


Im not sure what im gonna do. I have 3 choices: part it out, put it back as is, since the head is off slap some ITR pistons in there and get a little more comp.

I think I am lucky that no piston damage occuerd when this happened and just wanted to post some pics of what happens when u advance a s2s2 exhaust cam 10+ degrees.

 

ewwwww.....whyd they come undone meng??

pimp header btw

 

yah howd they come undone?

 

Well, when we did the install that cam gear had a slight wobble to it and im sure thats what caused it to back off and then slip. I didnt pay no mind to the cam gear being like that cause you could barely even tell it was wobling. I guess at 8500-9000 rpms that small movement at idle is soemthing serious in the upper end. If i decide to keep my set up I will be ordering the above cam gears so this will not happen again. As to how the cam gear got like this I do not have any ideas. It could of been that way from skunk 2 or it could of got messed up during install which I highly doubt. No point in blaming a company or blaming myself cause it wont fix my 8 bent valves.

 

What kinda cam gears were they? Sorry i just wanted to know! and ill make sure i check my gears before i go driving agian! thanks for the wake up call!

skunk2 gears

 

i told you to leave it stock

 

usually when cam gears slip they go full retard, but that is the suck none the less

one of my friends just fubared his h22 with a set of skank cam gears slipping

 

funny, before this i have only heard all good things about skunk cam gears.....maybe they slipping

 

I'm actually pretty impressed that it was able to advance 10 degrees with stage 2's and only have that much valve to piston contact. I would think you would have some serious problems with that much advance; more so than you do now.

 

been there done that. i had just installed my JUN 3s and full JUN valvetrain back in 01 or so and i forgot to tighten the cam gear bolts. slip, clap clap clap clap, a dead motor and 8 exhaust valves later i was on the road again. good thing i had a spare B16 head just sittin in the garage at the time.

 

yeah it sucks pretty bad. im going to overnight 8 new valves and I just picked up a headgasket off of someone on here. It should be back up and running before the weekend.

Oh yah im ordering some new cam gears as well.
