Title: Noisy tappet id
Post by: EMD on 21 July 2015, 09:52:34
I've done 3 oil changes and used wynns tapped treatment
but still have one noisy tappet on the drive side  :(
Question is how do you identify the right one to replace when the top
end is all stripped down  :-\

Remove the cam covers and see if you can depress any of the tappets using the end of something soft faced such as a wooden dowel. They should be rock hard, but if you find one that bleeds down with a bit of pressure on it, it's duff.

They can be removed and cleaned. There's a guide, IIRC.

Listening closely you can tell which bank it's on, I've got same issue on mine. Until you get access to them, hard to tell

Thanks folks , the noisy tappet sound has never gone away with all the oil changes . I will do another few thousand miles first then if its not quietened down it will be time to rip the covers off  ;) Funny thing is though there was no tapping when i bought it and the oil was really bad , since doing the first oil change the tapping started  ???

Might be worth dropping the sump and checking the strainer is clear. Could be that you have loosened a load of crud and it's gradually blocking the strainer and reducing oil flow.

Serek did all that kevin when he replaced the front crank seal  :y Oil is super clean now so looks like its inspection time again  ::)

I've heard of folks using a short length of garden hose (or similar) and holding it to your ear and using it like a stethoscope to find the noise - at least it should give you a reasonable guide to the area to concentrate on when you get the cover off.

Well no wonder it clogs up if abused with all those components  :o By the time you have got to the lifters it will be nearly cold anyway  :y
