Yeah it did bent 4 intake valves. After I remove the cams from the head I checked them out and they look like they were never installed still looked new. There was no marks on the cams at all. I call XS Engineering were I bought them from and they took care of it. Crower sent me their new 20% stronger billet cams.

...Crower cams are gargage! ive seen them snap in half and heard
lots of horror stories. no reason to use them, you can make pleanty of power on a boosted car with OEM sticks.(ie. CTR,ITR,GSR)

oscarmayer

couple of things that come to mind that can cause this.
1- torque of the cam caps. if it's too tight it can cause not enough oil to reach the bearing surfaces and thus resulting in lockup.
2- oil pressure same result as #1
3- over tightening the timing belt. This is always over looked by tons of people. if you over tighten the timing belt, it can cause undo stress on the front bearing surfaces and lead to the cam not getting proper oiling on the front bearings and that leads to lockups and then failure.

in all 3 cases ANY cam has broken into several peices.

basically it all comes back to torque specs and oil pressure from what I have seen "So far"

hope this helps some.

oscarmayer

oh, forgot one 1 thing, did you mic the cam bearings specs, (i know you cannot really change a bearing out, but if the cam side is to beefy it will cause issues with oiling as well. maybe this is what happened? too tight a fit?)

the solution woudl be to line hone the cam journels to the proper specs when miced with the crower cams. IF this was the issue.

ghostskinner

yeah crower cams are **** the broke in my friends type r as well he was N/A

the soulution is not to get them i had mine torqued to spec everything was perfect, they still snapped, they tried to give me replacement cams but why would i risk it again, and the next day my buddys cams broke too

Have people been having problems with crower ls cams too?

akstunt600

wow! i thought we were the only ones we broKe a cam @ nhra englishtown.

our motor is pushin 900+ whp, but regardless it still doesnt effect cams that much our intake cam broke right after the 1st cam cap.

we were runnin a fairly heavy seat pressure nothin to fancy though and right before our DNF pass we laid down a really low boost run and hit a 9.1

yeah NRG saw first hand what im talkin about. we were completely pissed

i cant believe brian crower actually covered them though.

dscivicdx

i have never heard anything bad about the ls cams, only the vtec cams. i had a friend have some break on him a few years ago. he was the first and only person i know that ran their vtec cams.

I think you meant Crower rods, right? I remember you posting before about the pin bushings wearing out and needing to be rebushed </TD></TR></TABLE>duuh, yeah... I have been so sick this week. I'll fix my post, thanks

earl

The trick is in the heat treating of the cam. You want to harden the lobes of the cam while not hardening the area in between the lobes. If you harden between the lobes too much, it becomes brittle and snaps. Crower has only had this problem for about 10 years now...

sp00led

So these problems with crower cams are they for the non-vtec cams as well or just all crowers in general? Reason I ask is I had a friend that was told crowers and one other brand (drawing a blank) would yield the biggest gains in regards to non-vtec setups.

sorry to hear this homie, but i'm sure you won't be down for long....

Got a head today and its going to Justice tomorrow. Hope to be back on the dyno next week. I will never use after market cams again. Especially crowers. I need to get to the track ASAP.

I have heard nothing bad about the crowers in the LS-T thread. I just bought some 402's from Turbo-LS and I hope they dont snap on me.
I have to much money going in the head for this to happen.

mrDFWmechanic

i want to see some pics of these snapped cams somebody post one up

This thread makes me weary of my recently purchased and installed Crower 404s in my B18B.

H23_Del Sol

I was thinking of getting the cams made for a supercharger... now from hearing all these story's I don't know if I should... what other company's make cams for boost???

rmcdaniels

For a SC, many people like a GSR intake and an ITR exhaust, then dial out a few degrees of overlap with some cam gears. I'm running the Crower turbo cams on my SC car, but I still need to do a couple more things to it before I get it to a dyno. It's already made around 300 WHP with a set of GSR cams in it at 8 PSI though, so OEM cams are not bad for boost. Just stay away from big-duration aftermarket cams, we tried some and they sucksed for SC power.

H23_Del Sol

So is crower the only company who can be trused with aftermarket cams made for boost.... is there any other trusted company's

did you happen to get any numbers while you were one the dyno before they broke?

SoEvoL

had a buddy run 2 sets of crower cams in his all motor b16 crx, snapped both sets at the track. hes still a crower fan boy tho, breaks em and buys them again. using crower valvetrain too

just thought id add that.

i hear great things from itr cams + boost. but untill i can get ahold of some of those im sticking to my stock gsr cams.
