What the HELL happened here? That does not look good and this isnt the first picture I've seen of broken Crower cams. I cant believe that they cant get it right!!! Any idea on how this happened??

 

it happens because crower does not use any kind of copper coating on their cams and they dont make them to flex so they snap.

 

Join the "I have broken crower cams" club.

 

wow.

 

What would it sound like when that happens? Would you just know it was the cam?

 

As far as I'm concerned, only one thing can cause this to happen...improper heat treating. When you heat treat a cam it is important to only heat treat the lobes and NOT the whole shaft. The copper color you see between the lobes actually is what stops the heat treating process on the shaft. If the shaft is too hard, it WILL snap like this. Sometimes a reground shaft on a Honda core is actually stronger than a new billet. Everyone here thinks regrounds are not the way to go but they are wrong.

 

For a while, I've been looking into getting Crower cams for my GSR, but after seeing broken Crower cams posts every other week, makes me think twice about those cams.

 

**** HOLY!

 

let me guess, you used someone other than Crower for the springs/retainers. Most likely JUN.

High lift cam, retainer meets valve guide, cam breaks. Seen it before.

Didn't know the S2000 head fit on a B16, I guess it don't.

that is deffinatly not a s2000 head.... i dont know wtf they are talkin about. the s2000 has a single timing chain with a gear in the head that turns the cams

???????????????

 

my bad eyes, $2000 race head. You can barely tell it is a dollar sign instead of a "S"

 

looks like what happened to my brothers car, he was racing jack on the way to the dyno and the cam broke. the valve springs were not stiff enough and the motor was pretty much screwed

 

Damn. This is third time I've seen this happen on this board.

 

............................Sorry bro

 

same exact thing happened to my friend at battle. Broke his crower cam in 4 peices. His $2000 Endyne head is getting repaired.

 

Hell yeah Crower sucks

 

I've seen it 6-7 times, but nobody will comment on what springs/retainers they were running, or if they even bother to check for spring bind, or the retainer bottoming out in the valve guide.

Most aftermarket springs use a thinner diameter wire for the springs to allow for more lift AND a recessed retainer that will have a higher spring installed height.

The original poster lists ITR inners and Crower retainers on the info page.

 

I have Crower 63403's and I have had no problems. I'm using Crower springs, and Crower retainers.

My point exactly.

One case was using Toda valvetrain, another was using stock valvetrain.

 

Check TODAs site they talk about use of there cams with diff springs, but I have seen where use of stock springs are used but some are swapped using a diff part number.

Springs would be a good place ot start. Blaming Crower for the cam being broken, I dont hold fault there. I have seen a cam dropped and watch it break, that will happen, to be strong and have good wear resisntance it becomes brittle.

Another Obvious spot to check is Valve Lash, and even checking the Cam Jounals, if they were not checked when the head was setup that could happen to snap a cam as well.

Who did the work on the heads, I would be asking them questions like. Did you do any machine work to the heads, if so did you check all the measurements. Did you check the oil gap on the cam. EVER HEAR OF PLASIGAUGE

Did he warentee his work. Got the Right Valves installed in the right head. Are they the correct size valves for that block, if valve stem is wrong length that could be fun on the cam as well.

Check your Rods, Are they Stroker rods with reg pistons.

Any Number of things could be the reason but check those out first.


This Aint Yo Momma's Honda

 

WOW!!!!!!

 

Merlin, my points exactly.

Most people have NO CLUE about building a motor. The first book I suggest is "How to Hot Rod the Small Block Chevy" as it covers all the basics needed.

I picked up my copy (now LOST!) 20 years ago.

 

i thought that crower fixed that problem with there cams?

 

Im not too sure, but i've read good things about this book, any opinions on getting this one? http://www.amazon.com/exec/obidos/AS...321984-9512013
