  Q: How should you check and install piston rings before engine assembly on Nissan Quest?

  A: When preparing the Piston to take the new piston rings ensure the end gaps of the rings are correct in by checking on the piston ring side clearance. Prepare the piston/connecting rod assemblies and the new ring sets and lay them side-by-side in a manner that you place same piston on same cylinder during gap measurement and engine fitting. Push the top ring into the first cylinder, aligning it with the cylinder walls using the piston, put it as low as possible in the cylinder. End gap should be measured with feeler gauges between the rings ends till the right thickness is obtained and the ring must be in correct position in the cylinder bore. If the gap is too small use a file to trim the rings or replace the set as guided by the ring material being used. Additional end gap is not such a problem as long as it is over 0.040 inches; check for conformity to the maximum standards. If filing is necessary, take a file and secure it in a vise then apply lubrication on the jaws of the cylinder head then slide the ring backward and forward movement and at the same time check the gap for the right measurement then de burred in the edges. Do the same for all the rings, in all the cylinders, making sure to keep the rings, pistons, and cylinders synonymous. Once the end gaps are corrected install the rings on the pistons, the oil control ring is made up of three parts. Closely fit the spacer/expander into the grove with the anti-rotation tang in its right position and then fix the lower and upper side rail in place but it is preferred not to use a piston ring installation tool as it may harm the metal part. Once the oil ring components have been installed, centrifuge the side rails to ensure they easily run along the groove. Subsequently, put in the second ring (its identification mark should be placed upwards on the cylinder) using a piston ring installation tool; The second ring must be pushed into the middle slot without stretching it too much. Lastly, have the top ring fitted just like the previous one, with the mark at the top; as applied for the rest of the pistons and rings.
