Fook :shock:
yea, slight dei ja vous
these things suck, 75% of them have broken on me. This was the last set i ever fitted and ever will do, infact, its the last kent product i will ever use.
Coul it possibly be doown to the botls not having being torqued right orno locking coupound being used.
Will they be replaced or you going to try for a refund?

Nope.
On these engines, if a bolt starts to come undone, it will hit the cover before it falls out, making a horrible noise, allerting the driver. AND if you look at the pics, all the bolts are not in their threads, and it would be a mighty coencidence for all the bolts to vibrate out at exactly the same time. Look at the material failue, that is where the problem lies. They are make of monkey metal, some crap ally that resembles cast mud/sand.
Shit those pics look even worse than the other few craig showed me!
Shows the crappy manufacturing of them, and they must be made outa some damn soft metal to do that. Like the way the inside has been re-inforced but the outside aint, and has just bent like fook!
Whats the damage ben? 16 bent valves? any piston scoring/damage?

I wish it would get me somewhere, but i know it wont.
Racing components, not offered with any form of gaurantee. Installed incorrectly etc etc. Shame they just cant make racing bits withstand racing.

no lol id say he means the pulleys are made of a pour material which wont last!! iirc paul(infinicar) had some of these in which the pulleys broke on bedding in and ****ed the engine up!
shite man that sucks, after just gettin it ready n all!! bloody kent shite! :evil:

so complain!! they made of shit they should be able to with stand a beating !!
That is shocking how that could of gotten through the product testing etc.
They obviously researched there materials well.
Makes you wonder how many companys spend time looking into there product design and manufacture.

they 'SHOULD' of been, but my pullies were not in the country. Catcams pullies are 'strong' but they dont tend to clear the cover and the bolts grind on these, loosening them and then the pulley moves and valves meet piston, ask craig.
so what r u saying they wernt corectly fitted?
No, its pretty damn hard not to install them properly. ANd they have done countless 1/4 miles and thousands of road miles. Incorrect fitting turns up the first time you floor it.
These failed from fatigue, which shouldnt happen.

I dont think there was any.

Tell me about it, it was runing the sweetest it had ever done, and craig did spend a sizable wad on it. So not to worry, i will be helping him out. Shame i didnt even touch the engine, but i dont think it would of made a difference even if i checked. And it should of failed on me given the battering it was getting under mapping.
Strange thing was i mentioned to craig on the day he picked it up that i thought it was getting tired and feeling the abuse, probably not alot left in it etc. Then craig said that before the run on which it failed, he had a really bad feeling.
Maybe we should take note of instincts now.

so send them back get your money back and some compensation and dont take no for a answer at the end of the day they should be hade to a high specifiction eg hard driving hence the (performance cams) so they should last
well if it was me i would n e way !
:shock: any idea's on how bad the damage is yet ben? bent valves and anything else?
sorry to see that tho craig! proper shitter :x
Nothing more than a few bent inlet valves, nothing major.
But i am tempted to check the big ends to see if the mains have any flats on them.

Check out the problem jon had getting them to admit any sort of responsability.
You learn in this business that some people just stick their heads in the sand.

mate im in the trade and my mums in law i know my right and if it was me id be gunning for them at least £500 they cant sell shit like that..
yeah hopefully its just the valves that took the brunt of it!

Dont worry, they will be chased and questioned, but i'm not getting my hopes up.

Yea, good ecuse to upgrade to 35mm inlets ;)
lol whats it running now? i thought it was on 35mm anyway!
nope, 33mm std meganes.
If the head has to come off, and valves out, then the ports will be updated.
ive just replaced 4 35mm inlets this week due to a similar problem. there was no failure as such...the bolts retaining the outer of my exhauts vernier to the inner came loose on idle=6 bent valves. mine are catcams pullies and are very good quality....i repeat this was NOT component failure!
:shock: , do piper pulleys do this??

hey, your on 34.6 you said!!
YOU LIE!!!!! YOU LIEEEEEEEEEEEEEEEEEEEEEE :lol:
:shock: , do piper pulleys do this??
Not afaik, but i've only run them once or twice, but i've seen them fail in pictures in similar ways.
The reason so many people had to use kent a while ago is that piper didnt have any in stock and werent going to make some for a while.
there have been piper pulley failures aswell....not as many as kents tho
thanks ben, hope to god ive got a good set then.... got them from hillpower when eng was fitted
hey ben whens your pulleys going to be ready????????????
poor guy, must be devestated :(
yea, i feel really bad for him.
No worries, we shall be back and faster than ever though!
ah 34.6-35 whatever!!
43.730969737969921879399995895696mm squared more area!!!!!
thats gotta be 2 cfm more hahahahahaha.
Thats a disgrace - I think this should be posted from forum to forum hopefully so everyone who owns a car and visits owners clubs will see this..
They'll soon pop their heads back up from the sand when no ****er buys there shit...
ah 34.6-35 whatever!!

am i bothered? yeah but am i bothered tho? face....bothered?
:lol:
well, when you have your head in the sand, the only thing you can technically sell is what comes from the only bit above sand lol.
So before i get sued and this goes round any forums.
Kent have been making top notch cams for years and are professionals, their products have and are racing around the world, i'm not blaming the pulleys, i'm just showing the damage.
And dont any of you call me a liar!
IIRC im running Kent pulleys
have i got any spare cash to change them, NO ! :(
its like were all playing the lottery with fantastic odds lol.
*legal disclaimer*
JOKE!
its BOVERED or BOV'D stan
ow them pictures dont look nice.
sorry again craig and good luck ben to get the car back running asap.
If you need my help with kent let me know.
well i think u all klnow my view on kent cams....but heres a little re-cap....
http://www.williamsclio.co.uk/forum/viewtopic.php?t=5410&highlight=kent+cams
im still waiting for the head and cams to picked up for testing by kent...im still waiting for them to contact me concerning this matter......think il be waiting a long time too lol....mine was the cams tho...not the pullies.
the infinicar problem was due to ill fitted pullies iirc.,.....bolts not tight.
thats 4 cars that have fukt up with kents in now.......altho 1 of em apparently wasnt the cams.......but i know for a fact, it was quite quick 1 min..shit slow the next.....that was all kept hush hush tho.

Me too as I have RN1603 and Pulleys being fiited in mine. Total loss of confidence seeing this....

sorry fred, im not up to speed with gay cockney/southern tosh slang. u obviously are tho :lol:
matty, its up to you fella...we can change them if ur concerned

Thats a right shitter. Were the bolts tight enough? Could it of just sliped and then torn through the pulley bolt holes :?
The bolts were perfectly fine, they have done an extensive amount of milage, and if they are too tight, they break as they are the weakest bolts in existence.
Justin..
03-02-2006, 20:19
was it only one pulley?
also does it run clockwise? if it does that pulley would take alot of tension but still no reason to break!!
yes, just the one.
I dont think tension has anything to do with it as its not actually that high on cambelts.
Could the way that the pulleys been anodised, effected the material and caused the failure?
indeed....and in fact when they are left dirty for prolonged periods, this affects the surface treatment in an advers maner....making the material more suceptable to fatigue failure
good thing they are spotless then ;) lol
And no, anodising, or hard anodising does not affect strength.
it can lead to surface imperfections...which can cause rise to stress concentration. couple this with the fatigue loading and it can go wrong.
I just had a bad feeling before it happened! was weird as there was no reason for it! Everything was fine!
Shit happens i guess, I just seem to have bad luck with cars lol!
Like Ben says it should be back and better than ever soon enough :)
I think I need to speak with Ben about bigger valves, and whathaveya ;)
I've emailed Kent a couple of days ago too, and havent heard anything back!

No surprise there then! :shock: :evil:
Get some 35mm valves in there craig! Be rude not to when you need to buy new valves anyway?
All 16 buggered?
Good luck anyway mate, keep us posted! :)
kent probably kno that there not up 2 scratch...there prob getting them cheep and thats y they have passed them off wether they passed there quality tests or not......
my dads a quality manager for a company that makes and heat treats nuts and bolts, even though the quality dept dont pass off faulty parts, the directors and higher managers do because they kno they can make a profit on them!
