Mine too are noisy. I have been advised that you can get some stuff to put in the oil and run for a few hundred miles that might release them. Then change the oil for the thinnest that you can. Might work I suppose. I will be trying it myself soon.

Hi Steven, if you engine has hydrualic tappets and they are noisy, it means they have failed and stuck solid, they need replacing!
