2002 4.4 8 cyl x5 smoking exhaust help! (vid included)
Seeking some help on this issue. Today i fired up the car and all was well. Was driving for about 15 mins then had to stop at a red light. after taking off again heaps of smoke came out the exhaust. It billowed out for about 20 seconds then only small amounts were coming out while i was driving around back streets checking it out. This happened for about 10 more mins, then all seemed to stop. I left it running and jumped out and nothing.... then continued the drive to work(had more stops at lights and seemed to be no smoke) with no more issues.
I started worrying about it then went outside to check after about 30 mins of the car being off. When i turned it on it puffed out some smoke then dies down. When i hit the gas it would spew out abit then die down again.
Here is a vid of when i went out to check after 30 mins of being off:

Was thinking valve seals?
Havent noticed any increase in fuel consumption or oil (although this just happened today)
We have had alot of rain here in QLD, Australia but i dont think its condensation issues.
Any idea how much this would be to fix?
Any help would be greatly appreciated!
Forgot to mention: Car has 170,000kms but has been running as smooth as a baby with regular servicing every 3-4 months
