Noisy tappet

[mikekean]

One of my tappets seems to have got really noisy as if it has completly failed and is not pumping up at all. Its one on the pulley side of the cams, but obviously its going to be hard to pin point wich one just by listening.

When ive got the head apart is there anyway of telling which one is knackered, or is just a case of changing them all?

Thanks

Mike.

Are you sure its not the dephaser pulley?

Have a search for the video's just to double check

 

[mikekean]

def not as it does it all the time even when reving. not the same noise as the dephaser either. only thing i can think of is a tappet, doubt its a snapped rocker as the car runs fine otherwise.

Does it sound like this ?

[legohead01]

that sounds bad. what isit? isit the dephaser pully?

 

[Andyman]

Just pm'd you back lol

Never found out as i replaced the lifters followers and dephaser all in the one hit but the noise sounded like it was coming right over the top of the plenum rather than the dephaser. No wear was found on the lifters and followers even tho it sounds pretty bad

 

[legohead01]

i have a friend that has this noise. looks like a new lump in it then. and find out what is wrong with it when its out. feel like another engine out job comin on. ive only just put mine in today lol

 

[Andyman]

Its probably just the dephaser mate. Never heard of lifters and followers being a problem in these?

Got to point out i was running reprofiled cams at the time which apparently can make a difference although the noise hadnt happend before having covered 60k on them. Also the cars a high miler

On a stock engine and stock cams would be suprised if lifters and followers would cause a prob? best speaking to the experts on here tho

i believe i too have noisy tappets. it sounds like a sewing machine when revved and it increases with revs up to just over 2k rpm where the noise is drowned out by the engine volume. i did used to have a faulty dephaser and i know what that sounds like, i had it replaced at birchdown along with belts etc. but this sound is completely different as i said like a sewing machine. oil change didnt make any difference.

its the noise of a thousand pound coins just rattling round inside my engine lol

mine does sound a lot like that video tho

 

[mikekean]

Doesnt really sound like it does on the video, that sounds as if all the tappets have failed, but mine sounds like its just 1 if you get what i mean. ill try take a video tomorrow and post it up. it gets worse the more you rev it and turns into a fairly bad vibration when reving high.

 

[Andyman]

Thing is tho mate is sounded goosed but when it was taken apart all was fine.

These engines are pretty harsh.

 

[mikekean]

Yeah they are abit agricultural, but it never did it when i got the car. And it just sound like one as the tapping is every one turn of the camshaft, not 16 tapps every turn if you get what i mean. There is deffinatly something wrong, So it sounds like im not going to be able to find which one is faulty so ill have to replace the all unless someone can tell me how to recognise a faulty tappet.

sorry to hijack the thread but I've got a similar sound from the left hand side of the engine. I have booked the car in for a cam/aux belt change along with the tensioners on the 18th but i'm really worried about driving the car in case something goes wrong and i'm wondering if the dephaser needs to be changed. I have attached a vid of the noise so any comments would be gratefull.

Did yours do it all the time mate or only once the engine had warmed up a bit?

Mine sounds fine when the car is completely cold ie its not moved for a few days

Anyone got any ideas to what the sound could be? If I need to get the dephaser pully changed as well I need to let the garage know ASAP.

Cheers in advance

mine sounds more like this than it does the first video that was posted... possibly two different faults?

Thats what I was thinking, you cant really tell its an issue unless you get the bonnet up. It could just be me being paranoid but i'd just like to make sure.

Pretty much all the time from memory but iirc more so when it was warmed up.

Thing is with the dephaser, everyone kind of reports slightly different noices and all the vids sound slightly different due to different recording devices etc

From reading on here most folk report it sounding like a diesel.

Just took a video tonight. I had just started the car up so it was cold which makes me think its not the dephaser. Notice how the time gap between the taps, this makes me think its only 1 tappet. http://s20.photobucket.com/albums/b238/betaboy/?action=view&current=Video003.flv

Just my opinion mate and im no expert but if that was me id get the dephaser fitted. Its a extra 140 but its peace of mind so long as that is the problem of course.

What you got your idle at mate? sounds a bit on the low side.

Hard to tell from the vid. If its running ok apart from the noise then you could give it a oil change and see if that helps?

 

[mikekean]

Idles at about 700rpm, it was cold though picks up once its warm. Probably a bit low but for piece of mind im going to replace all the sensors to make sure its running spot on. I could change the oil but its still very clean, being a cup race car its never had dirty oil in it. There is no sludge build up on the components at all. But i might run a flush through it and change it just to see if it does anything. Deffinatly thinking its a tappet though. I mean what else could it be?

 

[Andyman]

Its hard to tell from the vid but just from hearing that it sounds like a typical harsh 172 lump and highlighted by the low idle with the sewing machine effect.

Not sure about the Cups but the ph1 usually idles higher when cold then drops back when warm. Thats defo on the low side, you can hear it chugging mate.


Cant see how it would be the lifters. Their a pretty much solid component.

 

[mikekean]

Yeah ive heard a 172 lump before and this has a noticeable tap coming from it. if you put a screwdriver on the rocker cover on the pulley side and put it to your ear you can hear it really well. The further you get away from the pulley side the quieter it gets. And the fact it never did it when i got the car it just started doing it one day. So it must be either a tappet, or my dephaser is completly knackered and is just noisy all the time. Only thing to do is take it apart i suppose.

mine has a noise now were as bad as these i dont think and its not constent , i comes and goses on ideal it takes a few second to come in at first from cold , but then it taps and sound like running metel to metel , and its over due oil chage so hope that will sort it

 

[BLUE-STORM]

what do people think this sound is , http://s308.photobucket.com/albums/kk335/BLUE-STORM172/car%20noise/?action=view&current=Picture030.flv

advise would be nice

 

[BLUE-STORM]
