its had a new tct, oil is mobil 1, it has always done it from the day i bought it 32,000 miles, it also when cold rattles at about 3500 - 5000 ish, when i say cold i mean with 2 temp bars on the dash but it doesn't do it when its hot, it's not injector noise it is more a valve or cam sort of noise

When you say rattle, do you mean like a tappetty noise?

That could be valve clearances.

My engine note changed considerably after having valve clearance done .

Rich, how much did Honda charge for checking and changing your valve clearances?

motogp1

Hi jamie. i had it done as apart of the 54k service (actual mileage was 51k).

The engine tone changes alot its a much deeper tone now , this is what makes me think this is what the op's problem is.

nashby

yes its a rattly noise, will have honda do valves or is it fairly easy to do ones self, nothing special in there is there? should they be done hot or cold?

j8mie

Cheers Rich.

My 54k service is early next year, so I might get that checked a bit sooner. Have you noticed any drop in oil consumption as well since the valve clearances were done?
