Message	i just did a compression test on a jdm motor i just bought with only 30k miles. i put oil in all the cylinders and let it sit for 2 days just in case if the piston rings were seized. all the cylinders compression was amazing except one that only showed 25psi. i tried multiple times but same result. what do i do now? is it a bad piston?
