Engine Smoking up + exhaust problems

[69jono69]

Hey i have heaps of smoke coming from the exhaust and also from the manifolds at the start and the car is sounding like crap and also this comes and goes and at the same point on my day drive it always stuffs up at the same point i have taken this car to several mechanics and it usually goes good as i take it to the mechanic so that the reason they can not find a problem the car is a Holden VY 2003 series 2 S hope some one can help me or give me any clues on how to fix it thanks

could be an oil leak that is spilling onto the manifolds? thats what it kinda looks like from here
other than that when you say the car stuffs up what do you mean? does it stall or misfire?

Is that oil or water on the ground out of back? If it's oil it doesn't sound good

it is a oil smell when it is on and also it misfires i gave up on it thought i wouldn't be a Jew and just take it to another mechanic for them to solve the problem this is the 3rd mechanic i have taken it too hopefully this time they will fix it and did i note i took it to Holden to fix and they had no idea what it was 160 dollers later and asked for another 130 to look at it even more :S
