Can i replace a 2e turbo piston ring using a 2e piston ring ?. My car is a toyota corolla using a 2e turbo engine. Thank you

remove engine from car , remove engine head , remove oil pan , remove each rod from cylinders

Head gasket is leaking into the cly. Do it again

Blowing black smoke means fuel mixture is too rich, possible choke is stuck partically closed.
Blowing white smoke especially driving off the traffic lights indicates either worn valve guides or worn piston rings. Valve guides require the head to be removed to replace valve guides.
Replacing piston rings means a major engine repair. It maybe better to get a reconditioned motor than replace worn piston rings because other worn engine parts should be replaced at the same time.

Turn the engine BY HAND until you see the intake valve open and the exhaust valve is closed. Put a long screwdriver in the spark plug hole and continue turning the engine until the piston is at its highest point. (the screwdriver will go up) If you keep turning the engine (Dont use the starter!!) the screwdriver will start to go down... turn it back until it is at its highest point. that will be TDC

crank shaft on tdc and cam shaft will have groove on top lined up with an arrow on top of cam seal retainer.

You are experiencing blow by,either rings not set properly or wrong size rings used.Piston rings are supposed to be aligned at certain degrees from each other.
Check compression in all cylinders.

I have toyota corona 3s engine it smokes black and fuel consuption is high we have changed the engine oil and cylinderhead gassecate but still black smoke is comming what should i do

Take your vehicle back to your mechanic, and have him perform a DRY, then a WET compression test. Please provide both readings back to me. In the meantime, ask him what it would cost you to him replace the piston rings. This is your problem. The 2 tests will simply verify me thinking.

If you remove thermostat water will circulate too fast and will not cool down, replace thermostat and check if your fan is turning in correct direction. Also make sure your ignition timing is ok. I found on some vehicles the waterpump seems ok but when vehicle starts heating up the impeller gets loose on the shaft. Check your brakes if they are not binding.

Hi,

To my knowledge, it should not loosen up by itself. If it does, then it is possible that they are worn out and must be replaced. Alternately, on some engines I have worked with, there is a locking nut that is used to tighten in place the adjuster stud or in some cases a double nut, that is one nut to lock in place and another to lock the first. On high revving bike engines, I also use locktite (superglue). Of course the pieces must be initially clean of oil otherwise the glue will not adhere.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.
