Well we went to CMI over the weekend and it was a blast. Our Street EG went 12.2 in street trim minus the back seats and plastic and passenger seat. our DA with the same set up went 12.6......not bad for our all-motor street cars with stock bores. But back to the topic, our race car didn't do to well.....we hit 11.6 but had a cam issue, our Skunk2 stage 3 intake cam cracked at the cam gear end and caused the bolt to back out and the cam gear to slip. We got really lucky that nothing happened to the valve( I don't see how it happened but the leak down says the head is ok) as soon as the car died I just let it coast to the end and did not try and start it again. Has anyone had this type of problem before on a new set of stage 3's. I did not impact the cam gear bolt on, It was torqued on to the cam. Any thoughts on how this might have happened?

 

i had that happen to me on some web cams... dunno about skunk 3's!...

 

seen that happen on jun3's, but thats because they gears were shot on with the impact gun and my only thoughts are that it stressed the bolt and caused a hair line crack of some sort on the cam.

 

sorry to break out of the topic, but does anyone know what would cause these gears to crack like this?

 

sucks to hear jeremy , ive never herd of that before .

and to the cam gear dood , over torqueing the bolts might , but the bolts usually breake before that .

 

That sucks Jeremy. Skunk 2 should replace the cams, but I'm not sure what would cause this other than a faulty cam or possibley over torquing the cam bolt (which you already said is not the case). Have the cams been used by anyone else....?

 

Dude, I had exactly the same thing happen on a fresh motor. Skunk2 stg 3 cams. The end by the cam gear just snapped off. The bolt held it in place so the gear did not fall off, we just could not get it back in time. Luckily the compression tested ok.

 

I've heard of Skunk2 cams going out like that before. In fact I've heard the same thing happen with almost every cam out there (not breaking in the same place, but breaking in general) Skunk2's do seem to break maybe a little more than others based on the number of stories I have headr. Hopefully they will stand behind thier product, and make good!! Good luck!!

 

damn, i feel you pain brother. the exact same **** happen to me last week. i called skunk2 and they said that they would warrenty it if i had the original reciept, but i bought my cams through a second party over the internet so im not sure what to do.

I don't like to see all of this. I have a brand new pair of these for my new motor..........

 

skunks been known to snap off at the gear end where the bolt is...but i was told it was only on the first batch...guess not?

Yes, s2 stg3 cams. They said they would replace them, theyjust wanted me to send the others back for them to test and see why it happened on a fresh new motor.

 

Just a question.....are you guys properly torqing them or just makin it tight? I kinda remember when people were breaking the outer shafts on axles because of using an impact wrench instead of torqing. Other possiblities could be: too much tension on the belt or very tight valve springs or the worst would be if the valves hit the pistons and stopped short for a split second and broke the first weak part in the system......

Cause and Effect.....

somebody ask tony1 what happened with a jun stage3 cam about 3 or 4 years ago........it broke in half in his hand while he installed the cam gear!!!!!!

 

maybe they aren't tapping the hole deep enough! double check before installation.

It's making 215hp,157tq. I think it would have done better if the driver had more seat time in the car. I will let you know what the car weighs later this week. it has only one seat and the dash and door panels with carpet and all the glass. last time the car weighed in at 2000lbs without driver, but i think it is a little lighter now. the car is still obd0 and we will be changing it to obd1. we mad our own header for the car and did the port work ourselves.

Well the valves didn't hit the piston and im surprised they didn't.....the leak down came out good. the timing belt was not tight and the gears were torqued on by hand not impact. It sucks that it happened and stopped us from running but at least the engine is not damaged in anyway.

thanks for all the replies
