not saying its your fault but you knew about kelford snapping cams 6 months or so ago people have talked about it so since you got so awhile ago why did you not just get some different cams or anew set.

 

yeah, definately not new, but sucks nonetheless. i am looking at cams now, and have considered the gsc1's/ cosworths, but don't want something like this to happen. the 8's dont have too many issues, but definately still worries me. i'm now leaning more towards the hks/ japanese made cams. maybe the 9's break more cause of the hollow cam design?

 

that sucks i would def call kelford and make a BIG deal about this..a 300 dollar cam ruins a 6k dollar engine...i would be pissed, hopefully everything works out in ur favor.

 

Tough for cam companies. So many things that can make a cam snap. You could be the best engine builder in the world or you could be the worst. I have no idea. Neither does anyone else.

People should honestly catalog their builds via video if the investment is over $5K for this very reason. Just my.02.

I wonder if someone can take the time to plot snapped cams vs. self install or shop install.... Would be interesting to see.

Hope everything works out for you.

 

Wow this is ridiculous, where you ever able to get a refund from kelford and any help from the dealer of the cam

 

be carful with gsc's they seem to be using kelford blanks and just grinding their grind to them.

 

Dang i was thinking about trying these cams too. Oh well I'll stick with my M2's for now. But yah this is a documented problem on the Mivec cams.

 

After a whole year, scary stuff man.

 

hope all works out for you thats crazy just seems like a weird place. now we have to worry about cam walk.

 

I"m glad I took these off my car I use to run these last year.

 

anyone know if a oem ix cam has ever snapped?

i have the newer revised kelford 272 in im hoping that problem has been fixed!

 

yikes, makes me feel alil better im using hks

 

Thats the first time i've ever seen this with kelfords

 

The early MIVEC cam blanks had the oil channel machined as a square groove, this sharp angle at the bottom of the groove allowed the cam blank to start cracks which eventually resulted in a broken cam.

The fix for the newer cam blank cores was to radius the bottom of the oil groove.



If your MIVEC cam has the square groove, it is a potential time bomb and should be replaced.

Lucky you. What cams are you running now
