Default Exhaust Smoke coming out the inlet?

I started my engine up over the holidays to let it run for a few mins as it had been sitting for about 6 months. I noticed once it got going that around every 5-10 seconds I'm getting what looks like a puff of smoke coming out of the #3 inlet port. Any ideas what this is likely to be and how to fix it? I thought it could be a timing issue but wouldn't that mean it should be happening out of port #2 at the same time?

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.

I haven't got the coolant system completed yet so I can't let it run up to temp properly at the moment. It's had a new head gasket awhile back so I'm hoping that's not the problem... I'll have to get ahold of a compression testing gauge then and see what that shows. Thanks for the advice
