He has said it all, for how long have you been using the Car? What's the make? Did you used approved engine oil? How often do you check the oil level? These are endless questions!

When an engine starts smoking, its an indication that its coming to the end of its service life. The piston rings are usually the ones that take a larger toll in the entire engine operation and are more succeptible to a higher rate of wear.

This is mostly caused by poor maintenance and low quality dervice parts such as engine oils or filters.

Once they begin to loose their strenghth as well as increased wear in the cylinder bore causing it to widen, engine oil begins to seep up and into the cumbustion chamber causing the oil to ignite with the fuel/air mixture which will ultimately mean the whitish smoke coming from the exhaust.

It may also be caused by worn out valve oil seals allowing oil also to slip down the valve stems and into the cumbustion chamber.

Unless a major overhaul is carried out, the engine will eventually knock damaging the crankshaft bearings, pistons and connecting rod journals, oil pump, camshafts etc.
The valve stem oil seals would need to be changed too as well as the valves relapped and ground.

I would simply advice you to have a replacement engine fitted as a more economical and reliable measure.

I just took this cylinder head from a a Toyoa Sienna. Imagine the amount of sludge in the engine. I've never seen it like this before. Terrible!!!!
