At idle my exhaust puts out white smoke, the kind that you see on a cold morning, but its not that cold. I have no white stuff or bubbles in my oil.
Can a blown head gasket be so that there is no evidence by looking at the oil?
Is there another way moisture can get in exhaust ?

 

White smoke usually means you popped a head gasket. You may want to do a compression test. DId you check to see if your coolant level is down?

 

I know I have a coolant leak, the resivor has hole in it that will get fixed today. Compression test, damn looks like i am going to do my spark plugs too today,lol, while I am at it huh.,

 

Pay attention to how your plugs look. If you are going to replace them, lay them out in the order they came out so you can see what cylinder is what. Any plug that is unusually clean or a different color would indicate a suspect cylinder.

 

Shoe do you think it could be anything else?
When I remove the head/s should they be checked for warpage?

 

Before you go removing the heads, check the plugs and the compression. Are you loosing any coolant beside the hole in the resivor? If you were low on coolant and the engine temp went too high, you could have warped a head.

Does the exhaust smell funny?

 

Head gasket, crack, warpage. Don't assume, though. Do some diagnostics to confirm what it is before ripping the engine apart. If you do end up with head sealing problems, it would be a good idea to have the head(s) checked for flatness while off.
