Do a compression test.
No compression could be various things from your piston to your crank start with your piston by doing a compression test
by compression test
Do a compression test on each cylinder looking for one that is significantly lower than the others.
Take a compression test Could be a bad head gasket Bad plugs? Bad wires?
You may have very worn piston rings, letting oil through. Take it for a'compression test'/
Bad spark plug or wireBad valve (do a compression test)Bad piston "
The only way to "check" a piston would be to remove it and visually inspect for damage and wear.Make certain that the piston is not cracked or otherwise damaged.check the ring grooves. Use a piston ring and a set of feeler gauges to determine the amount of wear. Excessive ring groove wear can result in piston failure and if the piston shatters, it can cause the engine to fail completely.Next, use a micrometer to determine the difference in the diameter of the piston between the top and bottom. The piston will wear and if the difference between the top and bottom is too great, the engine will exhibit "piston slap".Check the fit of the wrist pin, it should be tight.HOWEVERYou can run a compression test and get a good idea whether the piston is functioning somewhat correctly.
One of the parts in the piston are the piston head,
If you're getting gasoline in the oil, then you have bad piston rings that are allowing gases into the crankcase. You can find which piston(s) have bad rings by doing a compression test; a cylinder with bad rings will have lower compression.
A dry compression test measures the pressure inside the cylinders of an engine with the fuel supply disconnected, while a wet compression test involves introducing oil into the cylinders to test for issues such as worn piston rings or valves. Wet compression tests can help determine if low compression is due to piston ring or valve issues, while dry compression tests are often used for a baseline measurement of engine health.
Bad spark plug? Bad plug wire? Bad valve or piston - do a compression test
