To do so, the cylinder head, upper part of the oil pan, and the oil pan itself have to be removed from the engine before pulling out the piston and connecting rod assemblies. Look for any ridges that are at the extreme end of the ring travel in every cylinder and which must always be trimmed using a specific tool to enhance the lifter of the piston. After that, demarcate the crank shaft, turn the engine to have the crankshaft on the upper most side after removing the ridges. With the connecting rod in place and the piston at TDC, measure the connecting rod endplay with feeler gauges, meaning that if the amount is over the service limit, then the new connecting rods may be required. It is worthy to identify the connecting rods and caps then you can loose and remove the connecting rod cap bolts without dropping the bearing insert. Slide the connecting rod/piston assembly out through the top of the engine you made, be sure to take out all ridges. Stack the caps in order and place the inserts back in position to avoid further harm in case of a review. Before fitting new piston rings the end gaps should be measured and the piston ring side clearance should be checked. Lay down the piston/connecting rod assemblies and new ring sets in order to ensure that corresponding sets are assembled together. Place the first cylinder and the top ring at their proper position and measure the end gap with the help of the feeler gauges and get on with the adjustment if the measurements are not correct. It is to be noted that the correct orientation of the rings must be placed. The first step to fit the rings is to properly place the oil control ring, middle, and the top rings. Scrub the cylinder liners, deburred the corner radii, and make sure the crankshaft is inserted before setting the pistons/connecting rods in. Oil the piston and rings, apply a piston ring compressor and then thread the assembly into the cylinder properly. Inspect the clearance of the connecting rod bearing oil by using Plastigage, comparing the sizes of the bearing as well as its cleanliness. The usage of Plastigage should be skinned, on the bearing faces lubricate using grease or assembly lube, and finally screw the rod cap bolts up to the appropriate torque. Apply the same process for all the assemblies, make sure they are clean and they are installed with right orientation. Last but not the least, perform a crankshaft rocking motion to feel for binding and for the second time, check the connecting rod end play and fix them if there is some problem.

Rotate the crankshaft by hand to check for any obvious binding.
