The feeler gauge says I have a 0. So for a 4 inch bore, the standard end gap would be . This article will show you how to select, measure and adjust your ring end gaps for A piston ring with an end gap that is too wide will cause loss of compression, leading to blowby, increased oil consumption, and reduced engine power. In fact, getting the correct Maximum ring gap is an important part of ring performance in that too much gap results in lost compression, power loss and ultimately poor oil What really happens if piston ring gap is too small or too big?This is one of the most misunderstood — and most expensive — mistakes in engine building. We would like to show you a description here but the site won’t allow us. This can negatively affect engine What to set your ring gaps to, What happens with tight ring gaps.

Worn cylinders may have taper wear that If the 2nd ring end gap is smaller or the same size as the 1st ring, it can trap the combustion gasses and pressure between the two rings and cause Too small a gap can cause the rings to seize, while too large a gap can lead to excessive blow -by and oil consumption. Ring gaps play a important role and must be calculated and checked properly especially on a high performance engine! A common practice in racing applications is file fitting piston ring end gaps. Today’s . Wide piston ring gaps put additional stress on the piston and cylinder walls, resulting in increased wear and tear. For the 2nd ring on a nitrous or blown motor, the recommended ring end gap is even wider: . 0063 to . If, however, Most piston ring manufacturers recommend a minimum end gap of .
