Default Re: 98SW2 Re-Ring project

The piston/ring manufacturers have conducted tests that demonstrate that engine performance does not suffer when the hot running end gap is in excess of 0.040 and all gaps are lined up vertically. The tests also show no noticeable change in blowby when all ring gaps are lined up vertically at any end gap.

The easy way to put those rings on the pistons is to use some 0.007 steel shim stock. Wrap just 1 turn around the piston and slide the ring down the shim. Let the shim stock cone slightly and the ring drops on the top and will slide over with no risk of springing the rings. Be sure you dress off any curled edge on the shim stock so you don't scratch anything. The shim stock is also sharp so keep blood off of clean steel and aluminum as it will cause corrosion.

REWARD EXCELLENCE!
