To determine the ring end gap look for your application in the. There are three functions of the piston rings as follows: To provide a pressure seal to prevent blow-by of burnt gases. For example, a 4.000 bore would require a minimum end gap of. Rings also control oil and transfer heat. ET piston rings come pre-gapped, however, it is always best practice to check your end gap before installation. if the gap is too small, file the gap with a points file, if to big, get a smaller set. The piston rings are the key defense against cylinder pressure leaking into the crankcase, thereby leaving horsepower on the table. Real easy to check, put the ring in the cylinder, and check gap with feeler gauge. Why is there a gap in piston rings When the engine warms up, the piston rings will expand, so you’ll adjust the end gap to account for this thermal expansion and strive for the optimum seal. Too much gap and it will burn oil, not enough, and all sorts of bad things happen. When it comes to the top compression ring of the piston, most manufacturers suggest a minimum end gap of.004 inches multiplied by the piston’s bore diameter. Ring sets come pre gaped for the stock bore, and a few "standard" size over bores like +.10 +.20 and +.30 over size (or their metric equivalent).
