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.

so what r u saying they wernt corectly fitted?

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!

i thought the pullies on the car would have been cat cams or your own... its a well known fact of the fraility of those things.. what a crock of shite.. lol yes indeed Monkey metal.

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.

BenR
02-02-2006, 23:42

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 !

BenR
02-02-2006, 23:47

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..

richy
02-02-2006, 23:52
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.

BenR
02-02-2006, 23:58
yeah hopefully its just the valves that took the brunt of it!

Yea, good ecuse to upgrade to 35mm inlets ;)

richy
02-02-2006, 23:58
lol whats it running now? i thought it was on 35mm anyway!

BenR
03-02-2006, 00:00
nope, 33mm std meganes.

If the head has to come off, and valves out, then the ports will be updated.

stan
03-02-2006, 00:01
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!

richy
03-02-2006, 00:01
cool, get it done ! :D

ah 34.6-35 whatever!!

BenR
03-02-2006, 00:06

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.

stan
03-02-2006, 00:07
there have been piper pulley failures aswell....not as many as kents tho

jay s
03-02-2006, 00:10
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????????????

No worries, we shall be back and faster than ever though!

thats gotta be 2 cfm more hahahahahaha.

Daz.
03-02-2006, 00:58
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...

BenR
03-02-2006, 01:04
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!

Daz.

03-02-2006, 09:34
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.

Thats a right shitter. Were the bolts tight enough? Could it of just sliped and then torn through the pulley bolt holes :?

BenR
03-02-2006, 20:14
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!!

BenR
03-02-2006, 20:59
yes, just the one.

I dont think tension has anything to do with it as its not actually that high on cambelts.

arj256
03-02-2006, 22:18
Could the way that the pulleys been anodised, effected the material and caused the failure?

stan
03-02-2006, 23:15
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

BenR
03-02-2006, 23:59
good thing they are spotless then ;) lol

And no, anodising, or hard anodising does not affect strength.

stan
04-02-2006, 11:33
it can lead to surface imperfections...which can cause rise to stress concentration. couple this with the fatigue loading and it can go wrong.

Craig
04-02-2006, 20:07
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!

stew

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! :)

Mattie
06-02-2006, 11:35
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!
