Elite Engineering Catch Can Problem: Car won't start and left me stranded - Page 2 - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

Godon Hutchinson · 06-28-2011, 07:57 PM

I will look up the grade of bolt tomorrow at work. I would think a case hardenedbolt/stud would be a better choice. Like Pollock said there are a lot of static loads/vibrations at that point do to the lenght of the shaft and the weight of the can. I do know a little about metal propertys i have been a welding inspector and non destructive testing tech ie: xray, mag particle, ultrasonic inspection for over 23 yrs.

I have one.. now I'm worried!

IndeedSS1Wrote: Elite doesnt supply that stud do they? No they dont the stud is OEM.the only thing we did was remove the nut on it that holds the groung clamp then theard the rod on to the stud end of the bolt.I got a call back fom elite but was outside. steve left me a message and said he would call tomorrow. Icalled back and left a message again and sent a email with pic of sheared stud. Its fuzzy but here a pic of the damage to my can.

Sounds like you guys have discovered a serious issue. I suppose it may be on Eilte to start including an appropriate grade stud in their kit?

Godon Hutchinson · 06-28-2011, 09:54 PM

IndeedSS1 wasnt there someone on here that came up with a L backet piece that mounted on the stud thats not used from the OEM airbox location if you had a after market coldair intake on your car. I thought there was but cant find the post anywhere. Thanks for any help.

looks like the rod was over tighten...

I did and posted pictures, but a couple other guys did the same before me. I just took their idea and did my own thing. It was mounted on the strut tower stud that the removed stock airbox used. I'll see if I can find that thread.

I didn't tighten mine any more than snug but only because I was afraid of stripping the aluminum threads. It never occured to me that the stud may be stressed. But when asked the OP said he didn't overtighten the dowel.

Godon Hutchinson · 06-28-2011, 10:20 PM

My rod wasnt over tightened to the stud. looking at it from a metallurgy stand point the shear appears to have been caused by vibration of the can weight and rod lenght that started a small crack that over time sheared thru the bolt. That info coming from the test lab results run from the inspection company i work for and our in house level lll metalurgist

Godon Hutchinson · 06-28-2011, 10:30 PM

IndeedSS1 Thanks thats what i was lookin for ,ill have to get me a small piece of plate from the shop tomorrow and bend it, drill the holes and mount it to the stud from the oem airbox location.

I couldn't find the thread showing multiple driver side catch can mounting. Did my two pictures ring a bell or was it something else you were thinking of?

I found it. Start at post #65 and scroll through the rest of the thread. http://www.camaro5.com/forums/showth...te+driver+side

I don't have one of those cans but just from how the attachment is, looks like you are creating a sheer point. Using a properly rated bold should help prevent a failure such as this but, I think a better designed mount is in order.

Godon Hutchinson · 06-28-2011, 10:51 PM

Thanks IndeedSS1 thats what i was looing for. You my friend ARE THE MAN.

post up a close up of the fracture surface and I may be able to tell you how it failed.

does it look like this:

my guess its that it does look similar (fatigue cracks), and the vibration was to much for the moment arm. A better grade bolt would work... but a relocation would be best as you will still be fighting that moment arm.
