Hello folks,

okay - rattling noise when idling, particularly when engine warm. I want to say 'noisy tappets' but have absolutely no idea what noisy tappets are or how to go about diagnosing them and fixing the problem.

apart from this all seems peachy....

any advice?

THanks

If

it is the tappets then, get yourself a good flushing oil follow instructions, then get yourself some 0/40 mobil 1 oil and changew the oil, if the tappets are still nosiy, then you got lots of money to pay out sorry but they are hydraulic and cost and arm and a leg to do :(, thats if it is the tappets.

A flush, and a change of oil and filter (only use a genuine Mazda one) normally does the trick..

replacement is expensive, but I have read of people taking them out and cleaning them.

They work like two tin cans, open at one end.. one just slightly larger and sliding over the other so you have a sealed unit..
At one end is a one way valve, just a small hole with a sprung loaded ball bearing to seal it. any dirt in there, and the valve won't seal, and the HLA won't pump up properly. this gives enough clearence to make the telltale ticking noise.
