Right as I said in the other thread, I was expecting to see damaged lifters and possibly scarred bores the head where they belong. Didn't find this though, all bores were smooth and the lifters looked fairly regular to me apart from a few discolourations of the metal (see pics) Can anyone tell me if they look right? The lfters were only higher on the right hand side as they sat in the head, does this point to cam damage somewhere?














Cheers for any advice/help

 

just a quick question , how did you take the followers out , i am gonna take mine out as i have a top end tap just to check they are ok

 

Rocker cover off (charge carrier off hoses off etc) then undo the nuts of the rockers and lift them off, then you can just pull the tappets out.

 

with your fingers , is that how easy they should come out ,
have you cured your rattle or tap?
i am having a tapping problem

 

No not cured I want peoples opinions on the photos and their ideas. Yeah pull them up, as they go back in they sort of float, its all lubricated so come out easily

 

The reason the ones on the right are higher is because the cam lobes are at there "High points" under those two lifters

 

Thats what i presumed but just checking.

 

scortpower - if your engine is 16v its a lot more involved than the cvh engine.
s2steve - imo them tappets look quite worn to me.

 

Really? I don't really know what to expect them to look like. Do you think i should replace them and see if the knock goes away?

 

is it a knocking or is it a tapping noise??

 

what are the cam lobes like..... nice and smooth?? how old is the cam and tappets. if you replace them, you really should replace the cam aswell.

 

As said, you need to replace the cams and tappets together. Wouldn't do any harm anyway
You sure the noise is coming from the head tho?

 

Right, well the cam was fitted as a kit about 2000 miles ago. Don't know about the lobes, from what i can feel they are smooth. I can't afford to buy a whole new cam kit and get it fitted

 

Its hard to distinguish which of those it is, it sounds like a loud tapping, louder than the normal tappetty sound

 

From the photos the tappets look ok.... One question i have is , do you know what the oil presser is?

 

I have a guage in the car, it reads between 40 - 60 when driving (warmed up) (60-80 when cold) and on idle t tends to drop to between 25/30-40 when warm.

 

They look a bit on the worn side to me but may just be the picture. Take the cam out and have a look at the lobes. If the tappets have gone there is a good chance the cam has aswell. Go and buy a new camshaft and tappet set from a motorfactors. A new standard cam kit cost me Ł95 nc vat. Hold a ruller or a straight piece of metal across the tappets and you will see if they are worn. Also check that the button on top of the tappet dosent compress.

 

Will double check the tappetts today, they seem smooth and in shape, just with the odd colour changes on them. As for buying a new cam, I wont get a standard one as the head is stage 3 and the rest of the engine is upgraded. The sensible thing seems to be buy a newman with solid lifters as these hydraulic ones seem to have caused me nothing but trouble. This kit has only seen 2k miles since it happened to the old one!

 

its a cvh turbo mate, so its easy enough

 

Fitting a standard one would be a waste of time as the head is stage 3 and the rest of the engine is also ugraded apart from standard boost. I guess the best thing would be solid lifters? But if the tappets look fairly ok what can be making the loud tap/knock?

 

Worn lobs on the cam, it could be that the tappets are not inflating correctly in operation. what sort of noise do you get. i know describing this is not as easy as it sounds. would you say its a slow rhythmic tap this increases with engine speed indicating that may be one of the tappets is at fault, or a more general noise tat gets loader with engine speed?

Steve

 

Well there is always a light tapping sound, but i've had this with all cvhs. The worrying noise is only really audible at idle and its more sporadic than rythmic i think, if you give it some throttle and let off the noise kicks in as the revs go back down. Its like a loud tap or a light knock. Lol its very hard to describe!

 

mines similar problem , it also idles a bit funny at times and when you drive it has a slight hick up but if you give it some it runs fine ,
is yours running normal or does it have its moments when it runs a bit off ,

 

I Don't know really mate, its never really been running right in the 6 months i've had it! I know its a struggle to overtake a vtr at times which is very depressing for a hybrid t3, stage 3 head, fast cam, exhaust filter and low comp bottom end!

 

I really think you need to have a proper look at the cam itself. I would also line all the followers up on a really nice flat surface and see how they compare in height. They do look rough for 2000 miles, but not dismal.

With the cam out, you should be able to see characteristic differences between cam lobes, remember that Inlet and Exhaust lobes will look different from each other, but I still think you've probably got a fucked lobe somewhere.

Or, how about a completely random slant on it? My first ever fundamental CVH mistake 8 years ago was to assume that the tapping that I could hear from it was Lifters. I got them changed at a garage and the tapping was still there, turned out to be a blown exhaust manifold gasket.

Also, don't want to sound patronising, but you do know that the lifters should be replaced in the position that they came out of once worn in?

 

I.e back in the same bore? Yes i did that. Cam out means head off right? Which means new headgasket etc, not sure i'm up to that myself!

 

No, it doesn't. It's not that hard, although it does mean removing Cam belt.

You can do it though, if you are very careful. Just mark the position of the belt on the pulley and make sure it doesn't move on the bottom pulley. Undo the 19mm nut on the Cam Pulley before you do anything (Car in gear and handbrake on etc). Mark the distributor position etc.

I'm sure you can get the cam out on an MFi RST but its been that long!! They come out easily when you're on EFi, but not sure about clearing the metering head.

When you remove it, you need to guide it out or it will 'clunk' along the cam journal bores and possibly cause damage.

I'd probably closely inspect the lobes with the cam in first. Establish in your mind which are Inlet lobes and which are Exhaust lobes and compare them. You should see a noticeable peak, which may not be visible on a worn lobe.

 

Ok thanks, I don't really wanna drive it with the noise so might as well give this a go, however, it is EFI....

 

OK, should come out fine then.

 

So how do you actually get to it? And as for marking the dizzy? How does that work with coilpack?

 

lined up the lifters, they all seem the same height.

 

If you have no Distributor, then there's nothing to mark!!

 

Haha fair enough mate just thought i'd check, I still don't understand how to get the cam out without taking the head off?

 

it comes out the side of the head once you removed the pulley and other bits , if you have a haynes manual it will show you

 

Maybe I should invest in one of those lol does it come out behind where the coil pack is situated then?

 

Here you go Steve mate' Might need to scroll down the page

Yes, once all the bits are off, there's a 2-bolt plate on the Cam pulley end. You take that out and the came comes out from where the Distributor used to go. Yours probably has a cap in the old dizzy hole. I just use a swift movement with the cam to knock that out. I have that down to a fine art now.

 

Cheers, i'll give it a go hopefully i will have the day off monday! Miller nice to hear from you again, I cant read that artcle though, its too blurred once zoomed in
