I think your oil is too heavy, and though this may not be the cause of your noise, I have found that you want to stay below 40 viscosity (I run a mix of 30 and 40 weight oil to achieve something around 35)

I have found that 50 or 60 viscosity oil makes engine more noisy, as I think not enough oil escapes from bearing journals to adequately lubricate bottom of bores, thus causing pistons to 'slap' from side to side.

My 2c worth - Good luck with getting this fixed.

Hi Ninka,

Anyone running Atomic's Cosworth pistons in their engine?

If so how many km's has your engine done and at what RWKW???

What is the operational noise of Atomic's Cosworth pistons like at idle?

Thanks

Hey Simon im running an atomic motor with the cosworth pistons, the motor is relatively quiet at idle but does have some timing chain rattle which sucks.

done 3000km and is running 498rwkw
