I have just fitted the second cam supplied by them and it has yet again failed and eaten ALL the lifters (which were supplied by them).

This is a new engine which has run a standard ford cam no problem at all.

The cam was fitted exactly how they instructed including running in. I even took the car to Gard engineering to carry out the work so they could oversee my work and verify it was done correctly.

It has done this in the time it has taken me to drive home which is about 5miles!! It has also snapped a rocker! Yet again a load of swarf in the engine which I get to shell out £45 for a new oil and filter! Thats excluding potential damage to the oil pump and shells!

NOT A HAPPY CHAP!!

I am trying to gauge how many of these items have been sold and if others are suffering these failures like me!

Mine was well out of tollerance(only discovered afterwards obviously) and caused 0psi oil pressure. Had to fecking rebuild my bottom end thanks to their stupid f***ing cam

Edit:
Gone back to Kent with no problems. I'd rather have to replace the cam once in a while than do the bottom end everytime

mate had one with solid lifters fitted to the zvh in his fez, proper wanker of a cam and a bastard to adjust the lifters, wouldn't idle.

ended up taking it to torque of the devil got them to sort it. its fine now

this was the beginning of the month

Dan, I can't believe you fitted another one.

I'll fly the flag for Newman as much as possible, but the hydraulic cam idea is not a good one.

never had a problem with my newman cam i also have the solid lifters, its an animal

went through 4 piper cams before tho on my old turd so this time went with newman,

think is down to how they are set up an ran in tbh, also what condition your engine is in to start with ie good oil pressure.

best letting the pro's do this type of job. . . you get what you pay for.

Fitted a Newman cam with solid lifters to a customers brand new engine which i built, lifters are a pig to gap, then they must be re-done once the engine is run in.
Now its all done though, she revs like a slut and touch-wood there has been no probs at all.

Get on the blower to Newman and see what they are prepared to do!

RAT8OY

Neather can I !! I spoke to them again on Thursday just to go through it all and they assured me again this would not happen!

Even though I had a sneaking idea this would happen again, due to them assuring me it would all be well and using engineering bable speak to convince me this was the case, I went ahead and fitted it, but hence why I did it at an engineers to help with the arguements about how it was fitted!

I will be speaking (possibly shouting) to them on Monday!

RAT8OY

As above mate, I have their hydraulic lifter cam not their solid lifter cam! The engine is spanking new and built by me. It has been tested and has no oil presure issues as she runs 18psi when hot at tickover!

I can assure you there is nothing a pro could of done that I didnt do! Hence I even had one stood over me watching me fitting it at the time! He worked and trained at ford including the testing for various CVH camshafts. He is of the firm opinion that hey have miss matched the metals.

RAT8OY

Yep, I hink I will have to go solid lifter now! I will be speaking to them on Monday!

Butchi

Im not from england so I dont understand all that you guys have wrote here about solid and hydraulic lifters with cam.

But the thing is now. There are no good cams to fit the CVH engine? Newmans with solid lifters are bull shit to adjust, more work than you wants to have. Newmans with hydraulic lifters are shit to? And Kent cams wont last more than a couple of 100 miles? Piper is also bad as Kent cams?

This is not a happy reading for a Escort turbo owner is it?

How will a engine run if the cam is worn?

No its not good, a lot of us are going back to Standard Ford Cam.

Christian and Beccy

iTrader: (14)

But as I have said before, can Ford even be trusted to not be outsourcing?

Look at Radiators and how the quality has dropped.

Also, get a Ford sump gasket and compare it to a Payen one. The difference is like night and day. There is no way on gods earth I'd fit a genuine Ford sump gasket and if you see the difference, you'd agree.

It is true, we are fucked for decent cams. Newman is the best available, but setting them up is a chore and its whats putting me off development and testing.

marky_g

after helping my mate with the solid lifter Newman set up i said i was gonna do for hydraulic set up but i don't think i'll bother now, seems no on has had a good experience

B16CVH

I think someone ought to get newman to make their solid lifters like the original RS16i ones, at least you can adjust them in-situ as opposed to keep taking them in and out to adjust!

Christian and Beccy

iTrader: (14)

I suppose if that could have been done, it would have by now. Someone needs to do something if you ask me, but its all about demand and we are small fish by comparison! LOL.

roro22

Is the jist of it if you change cams go for the solid lifters and get them adjusted after a few hundred miles by a pro or take a chance on a ford one

Christian and Beccy

iTrader: (14)

I guess thats roughly it.

RAT8OY

Yep this situation is truely shit! I cant believe after the hundreds of thousands of CVH made over the years, we cannot get a camshaft to work!! Or was it some sort of weird voodo ford used back in the day to get them to work?

Dont forget it wasnt that long ago ford were still making CVH engines! I had an N plate 1.4cvh escort for a while. Hatefull fuckin thing it was but with 90,000 on the clock the cam was a good as gold!

I am getting that pissed off with it, I am going to get shot of the car! Time for a ST TDCI Mondeo! FFS! Well at least it will tow my track car with a proper engine in it!

roro22

after seeing that american escort in the photo gallery do the americans make an alternative?

juffer

Me and a friend have also had issues with cams. Between us we have gone throught 5 cams including ford and kent. In the end im running a motorfactors copy for £100 with no problem and my friend is running a power engineering cam with doulble springs. No problems so far in the last 4000 miles.

I belive that the tappets are the weak link. The kent ones were braking up and some of the brand new motorfactor tappets were not turning.

RAT8OY

Yes I agree! There is not a mark or wear pattern on the cam itself! All the wear is in the lifters! Its very possible Newman are buying these in and being told they are of a certain grade/quality of steel and not getting what they are told! Perhaps somebody supplying cheapo ones and making lots of money!!

Christian and Beccy

iTrader: (14)

I think you'll find PE cam is Piper.

juffer

the pe cam is SX428T

Christian and Beccy

iTrader: (14)

Yes, but that don't make it, do they?

juffer

good point. I suppose they design it and piper make it. Prehaps there is 1 good one out of 10 lol. I think its just a fact of life that you have to keep changing camshafts on a cvh.

nigel b

get the lifters x-rayed to check the material
compare the results to the spec that newman will have

RAT8OY

Fair point, but it will mean I have to track somebody down able to do it and pay for the service! As far as I am concerned this is something Newmans should of done!

Although it would answer a few questions on CVH cams! Anybody fancy a group buy? At least then we could specify a cam and lifters we know there is a fighting chance of working!

Micky

Good idea!!!Off the top of my head I'd say NMS,Christian @ AP and Jamsport are the main CVH experts these days.These 3 tuners have loads of customers,so should be buying lots of cams each year.I know NMS only fit Newman cams now,and would be very surprised if Newman supply crap cams to them,as Newmans bad quality cams would give NMS a major headache,and no way could NMS put up with any company's products giving them a bad name.Same with any tuner really.Regards,Micky

Tony Turbo

AT LAST someone said it! NOBODY makes a decent cam for a CVH. Newman are probably the best but that doesn't say much to be honest

marksrsorion

same problem lifters fine a first but after about 50 miles started tapping like mad and lost all power had to take it to a garage and was told the lifter are gone no happy at all, oil pressure is fine around 25psi on tickover will be ringing them monday and try and get it sorted hopefully sooner than later as i can't drive the car and the garage wants it gone.

Havin pissed about with s2's for ages i must say i have never ever had a bad cam, the solid 1 i have now has been mint all last year even when we stripped the engine this year to build a new 1 the cam was totally mint no wear at all , its just been put in the new engine last week and the tappets are easy to set up if you follow a few rules but i guess its each to there own ,imo all the fast rst run a sort of newman cam
tim

I have installed in my naturally aspired 1.6 cvh the phase 1 cam and hydraulic lifters, and first thing I noticed is the lifters are noisy. I don`t know because , but the lifters sound as the weres something wrong, but the car runs aparently ok.

I have made about 4000miles since then , and all seems ok, but the sound the tappets do are like they were something wrong. Recently I open the rocker cover to change the gasket and I examined all, and there were no signs of wear in the cam or followers.

marksrsorion

hopefully sorted now, the follows were to blame i think, when the valve was shut the rocker was lose as hell could lift it around 5mm off the top off the valve, managed to get 2 out off the head and the bottoms off them were a mess all chipped and bit missing and really bad score marks in the bores, the rest i can't get out.
going to have to strip the hole thing down now and find the little bits off metal floating about in my oil.
one good thing is that newman said that he would sort it out so all is not lost.

Karlos G

I had this exactly the same last week, it's mad how they can just go to shit like that!

The lifters that wont come out the top just drop out the bottom mate after removing the cam, easy.
If you have scored the bores then you may well have written your head off, because you'll need to remove those score marks and depending how deep they are the lifter will have to much play and you'll have no oil pressure for that particular lifter
I take it you pulled them out using a pair of pliers rotating them left to right as you pulled?
If your head is ok, then flush the engine a few times to remove the remains of those lifter bottoms, new oil and filter.......... in fact do this anyway!!
I feel for ya mate! Good luck!

best cam i ever had was an svm320 serven valley spec cam was the bollcoks of an cam made by piper cams the pe cam is SX428T is an Kent 34 but powers used that name. and ahmed specd the Kent 34 for them.trouble is with std cam it does not rev well and not good for any thing over 200bhp with an big turbo.

Christian and Beccy

Alex, there are alot of good cam profiles out there, but these days the choice isn't so much with what profile works, but more with what cam will last more than 500 miles.

CVH cams made by Kent and Piper and anyone that uses their cams rebranded just aren't what they used to be IMO.

Karl

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!

Hope that helps!

B16CVH

Just out on interest (having a brainwave), most oil pressure guages/testers connnect either to the pump or the location of the oil sender/turbo feed.

It is obvioulsy the restriction of the oil movement which creates this pressure, e.g the running tolerances between the big ends, Mains etc etc...

If the head lifter bores/cam bearings were severley worn, would this show up noticebly on the pressure guage?

I have had the same head from the original S2 RS i bought back in 2001 which had full Mobil 1 service history etc... and it has had many camshafts fitted since and i have never once had a problem with any of them, i managed 28k on a Piper 285T2 (which had a shit load of abuse) and only removed it as i rolled the car and decided to go all steel. The camshaft was absolutley spotless.

It could be that people are using heads which are badly worn causing low pressure at the top end but showing good pressure on the guage due to the bottom end being ok???

Is this feasible....???? Answers on a postcard!

marksrsorion

my head was brand new cost me £239 was still in the ford bag and box with all plugs and covers, oil pressure is 80-85 psi on cold start up and drops to 25-30psi when warm tick over, the bottom end has been rebuilt 2k ago had 3 millers oil changes and filters, the cam was fitted right and a good brand cam lube used.

i don't think the problem is with the cam it's the lifters, 2 had already gone wrong on first start up sent back and 2 more sent out and was fine for 40-50 miles until it started tapping and losing power.

i've know doubt that newmans cams are made very well made i just think that newmans should not use the company which supples them with the lifters due to the problem so far.

i'm now going for soild lifters anyway which i've been told are alot better but last time i used these it took along time to set up, and on an 1.6 carbed engine seems abit over kill but if it sorts out the problem then i'm going for it.

B16CVH

Good choice, i fitted these a few months ago now to a customers engine. It was the Ph4 Sprint cam fitted to a fresh build 1637cc CVH. Engine made 146@ the wheels (6900rpm) with only a 34 DMTR

I agree they are a bitch to set initially, but once they are set and the engine run in, its just a case of using a feeler to determine the gap, remove the follower, mic it up and adjust to suit to the clearence specs.
