My Zed started tapping a bit last week and has done it ever since.

It sounds louder from the front of the engine, rather than the top which I thought was a bit odd.

Was told by Pete who used to run se Nissan that it sounded like the tappets and not to worry too much about it.

Problem is, although I'm not too worried....

Its REALLY pi55in me off.

Has anyone else had this issue ( I know its quite common) and how did you solve it ( without taking the engine apart).

Was going to use an engine flush then change the oil and use an additive (ametech restore or something similar), question is what have other people used ( additive wise)? And what grade oil to use (Pete suggested 10/50w )?

thanks mark, think I will do this in the winter...she can rattle away until then....she goes off the road in the winter...

Hi mate any luck with that flush and new oil, i picked some of that 10/60 castrol edge up today from eurocarparts some say use 10/40 but ive allways used 10/60 for the last 8 years and thats a lot of oil changes .I noticed its not called edge sport now just edge and it states its for bmw m engines .

I get all my oil from this place http://moto-oil.co.uk/

I haven't had a chance to change it yet mate. Was so busy doing sh#t for other people all weekend. Hoping to get it done next weekend.

My other half noticed it said for m series BMWs on it, she thought I'd bought the wrong one :)

Hoping I'll also get a chance to find out why my car also has a random misfire sometimes.
