CVH Cams
right when i get my car back im goin to be look for a new cam
herd bad things about Newman Hydrolic lifter cam kit
and kent are ment to be poor quality
that just leaves piper
or am i missing something
so basically whos using what and some opinions

aparently newman are the best wen set up properly with the lifters.
ive heard a few cases where piper cams have snapped!!! ive had kent in the past and not had a problem,but always gave them reguler oil changes. every 700 miles or so

either standard ford, kent or newman. kent blanks are weak compared to others, they must be run in correctly to give them the best chance of surviving more than one trip.lol Their profiles are good, newmans only offer the solid lifter cam, they have cancelled the hydraulic ones due to poor quality lifters, Ive heard it can be a bit of a pain and a tedious task to adjust the lifters.
Hope this helps

I cannot really recommend kent cams. I did bought cvh 35 kit last summer and get it installed by proper shop. Fresh oil and new oilpump installed,cam was run in properly. After 120 miles it was rattling and kent cams wount response e-mails. When i replace the cam, i would buy original ford cam only.
ps. what i have been read i am not alone with kent cams problems.

well my spec is basically stage 1
chip, -31,1 bar boost, piper exhaust, water/meth injection
made 189 at last RR
i just assumed a cam was the next step, i did want to use Newman but after setting up solid lifters in a mates track car i would not want to do it again,
maybe i'll just leave the cam idea then

I have in mine a newman phase 1 cam for one year and the cam is fine, with no wearing at all, but hydro lifters are noisy all the time and engine loses power at 5000rpm or so.
Because that I have ordered a set of mechanic lifters. They are a pain to adjust but I think it`s the best option now.
I think newman has the best material for the CVH cams.

You dont need to run in the Newman Cams either which is nice (not for 15mins anyway), just steady for 25miles!
Never had a prob with any of them to be honest, 285 T2, CVH 35 and Newman Ph4, all perfect for me!

My ex rst newer had any problems with camshafts. Rst that i now own got problems with kent cams kit and i am really interested to find out what was the reason why cam did last only 100-200km.

Karl Norris talking about Newman cams and CVH cam wear in general.
Check your Oil pressure!!
"Hello folks,
We worked with newman in testing and developing the hydraulic profile CVH cam before it went into production.
After extensive testing we found the cam and follower material to be EXTREMELY hard wearing and far better
than the original hardenable iron.(std material)
In light of this, anyone who suffers a cam lobe failure is almost certainly due to poor lubrication.
This is likely caused either by blocked oil feeds in the head for lubrication of the cam lobes, or more than likely very poor
oil pressure that 90% of RS turbos have these days.
Remember it is easy to blame a product, but when we have extensively tested a product before its production launch,
I can confidently say that most of you with failures should be looking at your engines first, as no camshaft can ever work without lubrication,
no matter how hard wearing the cam is!
To test your engines fit a decent quality mechanical oil pressure gauge and DRIVE the car until it is fully warm.
Then test the pressure at idle where it must be a minimum of 15psi, and then hold the revs at a steady 3000rpm in
neutral where you must have a minimum of 45psi. If your engine cannot achieve this oil pressure with hot oil, then the camshaft will never last. PERIOD!"

Right, I understand!
Cheers!
Cant find it cheaper anywhere, all the 15w/50 Fully Synth Ester Oils are about that price (Millers, Silkolene, Mobil etc..)

Christian,
Given that I probably build more CVH engines than any other tuner out there, as I have NEVER had a newman cam wipe a cam lobe out, I can say with total certainty that their chill cast cam material is far more suitable in a CVH engine. I do however see one common issue which is pitting of the solid follower adjuster screw where it contacts the rocker. This however allthough unsightly, has never caused us any problems.
I do believe from reports on here that some people have had issues with the actual hydraulic follower, but my above statement was based purely on the camshaft material, and not other factors, as hydraulic followers are always debateable in any engine, never mind the CVH.

The problem as I see it is that there are no quality manufacturers of CVH hydraulic followers left and certainly the strength of the cam far outweighs that of the follower.
This is coupled with the high spring pressures needed to control the valve-train and that fact that most people over-spring.
That's my opinion anyway.

may be we should have fitted a evo engine in his, at least then we wouldnt be thinking the hardest job out there is getting a cam to last !!!

LOL @ Gary,
Believe it or not it's actually one of my favorite engines! Call me a glutten for punishment!
That said they are incredibly durable and I'm continually getting more power from them, so I'm going to keep on punishing myself and keep building them! LOL
Christian,
I do not rate hydraulic cams in any engine, especially the CVH! However before this cam was launched we did test it for newman and found the durability of the materials superb! If you did'nt know the followers are NOT std CVH items they are EN40 grade steel followers, required to work with a chill cast cam.

Christ this is a can or worms,
maybe i'll have to go solid lifters then, didnt rely wanna do that as there such a pain to adjust
thanks for all the comments tho

standard cvh head that i plan to have worked, increased port sizes, polished and flowed,
2.1 zetec bottom end with c20let pistons, eagle rods and arp studs
stage 2 garett turbo
efi with 300bhp chip but plan to go for ms or go tech when i learn more about the system
Wondering what cam you guys would recommend. Engine is good for the 350bhp mark, i like a lumpy idle but just want driveablity more than anything.
Cheers

The problem with a hydraulic setup is that ignorance is bliss, I'm afraid. Have you taken it out and measured the lobes? Just because it's not noisy, doesn't necessarily mean it hasn't chomped the lobes away. The hydraulic follower is of course designed to take up the additional clearance and the only symptom will be lost performance, which will have happened gradually.
That is possible, not to say thats how yours is.

i know what im going to be doing this weekend lol!! taking it out to check! is there anyway to check its as its surposed to be? as in the spec? would i need to take it to a engineering place to get them to test it? other than checking for obvious signs of damage i take it thats all i can do?

and when did karl help test and develop the product?i was using this cam in 2001 and can never recall newman being mention on this site
when did ollie and tim move to newman cams

its only making 230bhp tuner rekons the head is the bottle neck its made all its power at 3.5k and just levels out
