gazzb · 29-07-2010, 20:15

I want to clean the tappets and Im scared of undoing these bolts..
Is there and gaskets/sealent etc i need to be aware of?
How can i clean the tappets?
Are they in any order of sorts?

Please help that tapping noise is driving me crazy!!!

Not to mention i would like to see if there is anything amiss which might be causing my poor performance/stalling.

undo them and your removing the rocker cover gasket bolts .

Bsmovies · 29-07-2010, 20:22

That's the cam cover bolts...

Also, there's no need to remove it to stop the tapping noise. The K is renown for having noisy tappets. Run some tappet treatment through it, perform an oil flush, then do a complete service. This usually helps.

Otherwise, only other way is to change the tappets but it won't be a permanent fix.

cooper1200 · 29-07-2010, 20:32

they rnt head bolts the head bolts r under that. the k series uses hydrolic tappets there is no way to clean them other than a flush realy. if they r realy bad u will need to replace them compleatly at 20 pounds each. (its amazing the amount of people that decide the tapping is livable once they find out the price lol)

As above really, the bolts shown are the ones that hold the cam cover on. If the thought of undoing those worries you then stop now. There is nothing you can do to clean them, just replace the weak ones. However that will involve removing the cam belt and cam carrier. Again, as said above try using a good engine oil flush followed by an oil & filter change using a good oil. If that does'nt work then it's a case of how much the noise annoys you versus the cost to replace the tappets, nothing will actually break and fail.

LORDPSK · 29-07-2010, 21:24

If you wanted to change the hydraulic tappets them you might as well change the cambelt at the same time as you would have to set the timing, remove the cam cover, the cams shafts, cam carrier and only then would you have access to the hydraulic tappets to remove and change, some members would advise if you went that far you might as well fit the upgraded head gasket, new water pump, thermostat, idle cog and belt tensioner. The work depends on your pocket, your knowledge of doing the work and making sure what you do is right or else you could end up with a complete usless engine if you get the timing wrong or fail to tighten a bolt correctly, If you have the bottle go for it, if not seek advice members are always willing to help. All this for a noisey tappet, cheaper and less hassle to turn the radio up a bit more.

Undo the bolts at your peril, the car will get instant HGF, and possibly explode in a huge great fireball!!!
Apart from that, perfectly safe

Hope this is helpful.

Cheers

I heard that if you undo those screws the spirit of the car will escape and it'll never work again!?

Ok so reading through the sarcasm

it's safe for me to remove this cover as there is no gasket etc?
However to clean/replace tappets it's a lot if work.
I really want to just look inside to see how bad/good stuff is inside.
I have hardly any power 1000-3000 and sometimes stalls. I know tappets are not causing this but I thought I might as well see if I could clean them while I had this cover off.
I've tried pretty much everything other than the engine itself. Im not listing the things I've done here I think ive already done that about 4 times so far lol

cooper1200 · 30-07-2010, 05:37

OK thanks I can reuse for now as I want to do this today (Not at work for 3 days so if there is any probs I have time to sort it)
I'm also doing a compression test today to see if thats an issue.

also going try pretty much all of these..

Wynn's Stop Smoke
Wynn's Stop Engine Leak
Wynns Hydraulic Valve Lifter
Wynns Clean Burn

steely · 30-07-2010, 10:13

take it you know that even with the cover off you wont get near the tappets, you would need to remove the timing belt, cam carriers and cams before you get near them, taking the cover offs not going to do anything

VespaV6 · 30-07-2010, 10:22

Don't waste your time or money on this job. Just get a new oil filter and new oil. The K series is a well known noisy engine and just looking after the servicing is all that it requires.

that and Wynns Hydraulic Valve Lifter treatment works a treat!! haha

Beatonator · 30-07-2010, 11:47

you all keep saying the K is a noisy engine... Really?

I would never have said it was loud... although I do normally have my music up semi-loud

it is fairly loud but i think its known as a "loud" engine due to things like this, and piston slap etc...

gazzb · 30-07-2010, 12:30

Well .. I tried the Wynn's lifter cleaner and doesnt seem to have made any diffrence I assume It may need to take a while?

As for compression test..
well...
erm....

120/65/75/75

Shouldn't they be in the 200's?
They are averages from 3 tests...
Mileage on the clock says 70k.. im think more like 170k

and I HAVE SERVICED THE CAR LAST WEEK...
Had to make that caps as everyone is saying change the oil/filter.. it was done less that 1k ago.

New
battery/cables
air filter
oil/oil filter
pollen filter
fuel filter
Sparks
Ignition leads
and then cleaned AICV

Ive set the idle at about 1200 now.. hopefully that will stop the stalling issue.

cooper1200 · 30-07-2010, 14:59

what do u mean u have set the idle at around 1200... the idle isnt adjustable as it is ecu controled.
that screw on the throttle body that everyone keeps thinking is an idle screw is a back stop for the throttle cam and shouldnt be touched ever.
