I have got smoke coming from my exhaust but only when

This answer was rated:

I have got white smoke coming from my exhaust but only when actually in motion.The coolant is definitely going down slowly in the expansion tank.I have taken it to my local mechanic and he has checked that there is no head gasket issue( he did gas test in expansion chamber), there is also definitely no crack or problem with the engine block. No overheating,the temp is always the same, yet still I get these intermittent clouds of white smoke when driving. Help..

No, we only communicate on here.

I thought it would be diesel.

Get him to check the EGR cooler for coolant loss.

Replace it, if found to be the cause.
