You have to disassemble the entire engine, remove the piston and check the rubber ring around that piston.

Yes!
The purpose of a piston ring expander is to make it easier remove and install piston rings. Because of the low torque they use, they help to prevent damage to the piston rings.

To use a piston ring compressor with a pusher, first, place the piston into the cylinder and ensure the rings are properly aligned. Slide the piston ring compressor over the piston, adjusting it to snugly fit around the rings. Next, use the pusher to gently press the piston into the cylinder, ensuring the rings are compressed evenly as it enters. Finally, remove the compressor once the piston is fully seated in the cylinder.
That means the 'O' ring on the 'hammer piston' is broken. You can often remove the top (CAREFULLY, there is a large spring in there) to get the O ring out, -or take the whole thing to a power tool shop.
Do a compression test on each cylinder looking for one that is significantly lower than the others.
To change the piston ring on a Contact Point TMX 155, first remove the cylinder head and cylinder by loosening the bolts and carefully lifting them off. Next, take out the old piston ring by gently expanding it and sliding it off the piston. Install the new piston ring by aligning it with the piston grooves and ensuring the gap is positioned opposite the connecting rod. Finally, reassemble the cylinder and head, ensuring all components are secure before testing the engine.
Seriously worn piston rings and more than likely a broken oil ring.
bent valve, burnt valve, stuck valve, broken piston ring, cracked piston, cracked head, blown head gasket.
