Quick update !!!

I have removed the aux belt and ran engine for a minute... :)

The noise remains  :-[ :-[

So this eliminates any aux items and tensioners.  The tensioners felt ok just spinning them with the belt off.

Any further ideas?

After further investigation, turns out to be worn / poor fuction hydraulic lifters causing noise :(

What is the best price to buy the lifters online?  (have found site at £22 each currently)

I kow you would be best changing all 12, but would it be so bad if I just changed the baddly worn ones??

Cheers, BP

IF it is the lifters then a dose of wynns lifter treatment is worth a go

Final UPDATE.....

Just got the car back from a mechanic friend, and it sounds as sweet as  :) :)

Changed all 12 lifters ... £180 for bits, and £180 labour + new oil and filter.

Most of the lifter were stiff, but a couple were locked solid and worn on the top surface, so that was definately the problem noise.

I don't think the Wynn's would have sorted them, but you never know.  Better to change them I think.

Let's hope no more problems for a bit  :y

Old topic I know but your video shows the exact same problem I've been having for some time now. No mechanic I saw was able to determine the origin of the problem so thanks!
Has the fix been durable then?

Again, many thanks!
