Hey guys I'm new to the forum, I have a 1994 toyota 4x4 with a 22re. I recently rebuilt the engine, new rings, bearings, pistons, gaskets,timing chain, oil pump, had the head reworked. The machine shop found a broken valve guide so it was replaced. Put it all back together and it ran fine for 1400 miles then started blowing white smoke again. I pulled the engine and put a new head on it, new head gasket, exhaust manifold gasket and got it back running on Memorial Day. It is still blowing white smoke, no water in the oil or oil in the water. No loss of power and trying to turn the motor over by hand is tuff so I think compression would be good. Along with all the new engine parts, it has a new fuel filter, fuel pump, starter, and exhaust. I am using only toyota filters and toyota plugs. I can't figure out the white smoke. I have no oil leaking anywhere and I know it is burning oil because I am having to put oil in it every other day. The coolant level has not changed.

Thanks in advance for your help.

When you put your hand in the smoke, does your hand get damp or oily? "White" smoke is usually water (coolant), and "blue" smoke is oil, but I'm no interior decorator. Since you're using up oil really fast I'll bet your hand will get oily.

I would start with a compression check, and I would inspect each plug as it comes out. The cylinder burning the most oil will probably leave an oily, blackened plug. A leakdown tester will give you a more precise indication of where your problem might be.

If you ONLY get the smoke on start up, you could have a bad valve guide (oil drips in overnight, then burns up). If you get it all the time, it could be bad ring-seating (or a lot of other things).

At this point, don't rely on how hard it is to turn the engine as a compression check. The correct tool is around $25 http://www.harborfreight.com/compres...kit-66216.html, which is, what, 2% of what you've spent on parts so far?

Pressure check the cooling system to see if the leak is external or internal to the engine.
