Dense white smoke usually means coolant is getting into the cylinders -- usually a head gasket. You're fortunate if you have dual exhausts and are only getting the white smoke from driver's side. You know which head gasket to check/change. Unless the leak is minor, you can usually determine which cylinders are affected by doing a compression check.

    Why was the head gasket replaced? If it was because of leaking coolant, or low compression on one or two cylinders, or white exhaust smoke, but you are still getting white smoke, it may be a crack in the cylinder head or block rather than a head gasket problem.



    If the engine still runs OK, keep an eye on the coolant level. If the smoking gets worse or your are losing coolant, and especially if the engine starts running rough right after starting, you may want to get it checked out.

Why is there loads of white smoke coming out off my exhaust bad an I think oil two ???


the main problem caused by white smoke is either steam which is head gasket leaking water into cylinders /and will also have condensation or water out of the rear end exhaust ,or if running ok and no loss of water in radiator and starts ok then could be a mix of fuel .but if you are loosing water then its the first problem.
As if it was oil burning then its black smoke you should have not white.

White smoke from exhaust


You probably have oil that spilled over onto the engine block and manifolds which is burning off while you drive. You could get some degreaser and clean the engine. You could also just keep driving it untill it stops smoking as long as it seems to be running OK.

Would a defective fuel pump cause white smoke from exhaust?


probably not. White smoke in the exhaust is a sign of either coolant or oil entering the cumbustion chambers (cylinders). Faulty fuel pumps usualy stop delivering fuel to the engine and it won't run at all.

If you are sure it is white smoke and the car overheats or looses water,The head gasket is bad.
Or It's valve seals or rings smokes (but the smoke would have a blueish tint)
