Exhaust Smoke coming out the inlet?

[Not Anumber]

Do you still get it when the engine has reached temperature ?
Not saying it is likely to be the head gasket but for peice of mind it's always worth doing the basic checks if you are experiencing this- Leave it running for a while and check your water level before and after. Compression test all cylinders to ensure 2 and 3 are similar to 1 & 4.
