Hello everyone.
Sorry if my English is not good.
This is a B18C4 engine. Original computer P72.
Body EJ1 year 1995.
It would emit white smoke just by pressing.
I decided to start by changing valve rubbers.
I brought original valve rubbers, I started to replace them and one of the locks fell into the piston and I couldn't get it out so I lifted my head from the engine.
We found the lock and put the head back on with a new original head gasket.
I installed the head gasket upside down and started the engine.
When I started the engine (for 2 seconds) oil sprayed from the engine head.
Here I realized that I assembled the head gasket upside down, so I disassembled it again and put the head gasket on properly.
I did not drain the water that mixed with the oil inside the cylinder.
When I put everything back together I started the car and the engine sounded great and healthy with no smoke.
After 30 minutes that the engine was running, I lifted the columns and since then the engine has emitted white smoke both when it is stationary and when it is in motion..
- The engine sounds very healthy
- The car drives great

What can be done about the white smoke?
Thanks for the help
 
Possible ring/ valve damage from compressed water?
 
Correct me if I'm wrong but you used the same head gasket that you installed upside down ?
 

Since you only used it for 2 seconds you might have luck but if you see white smoke, this is a clear sign that water is going up to the combustion chamber.

The other issue that can also cause white smoke is a leak in any of the vacuum lines in the instake manifold.

Reusing a gasket is not advised as the saturation and absorbancy condition can vary. A gasket should be assembled, then exposed to heat and fluid. A used gasket already having swelling due to the fluids should not be reused.
