1. Lack of engine cleanliness 2. Rough/Imperfect bore entrance chamfers 3. Burr on bottom of bore 4. Poor cylinder bore finish 5. Spiraling rings manually onto piston 6. Excessive spreading rings manually onto piston 7. Not using / improper use of ring compressor 8. Piston damage dents, groove damage Many things NOT rebuilders fault Computers (bad calibration) Sensors (bad sensor) EGR Valve (too much exhaust) Intake Manifold (debris, leakage, run hot)

8 DO NOTs OF REBUILDING

1. Insert rings squarely into the bore and measure end gap with feeler gauge 3. Use ring expander tool to install rings on piston, so as not to deform ringdo not spiral on rings 2. Adjust gap if needed by filing both sides of gap equally

10 DOs OF PISTON RING INSTALLATION

4. Install directional rings with the dot up (otherwise oil pumping may occur)

5. Install 2.0mm 3-piece oil ring with expander points up to avoid catching in drain-back hole/slot in oil groove bottom. 6. Stagger location of end gaps on each ring 180 degrees apart 7. Clean bores with hot soapy water & scrub brush, wipe with clean white rag to check for any residue 8. Lightly oil cylinder walls and rings with regular non-synthetic motor oil

10. Typical engine break-in: use conventional motor oilchange oil after first 3,000 miles / 4,828 kilometers. Use only synthetic motor oil if originally specified by manufacturer.

9. Properly tighten ring compressor so rings dont catch on edge of cylinder or pop out in bore (dont force piston if it is hung up)

Rpk, Rk and Rvk have replaced Ra as the most important baselines of measuring bore finish. These present a much more defined description of the actual bore finish surface.

BORE FINISH

Bearing Ratio Curve (% of material contact of cylinder wall to ring)

Reduced Valley Depth (Rvk) The oil retaining capability of the deep troughs which have been machined into the surface

Core Roughness Depth (Rk) The long term running surface which will influence the performance and life of the cylinder

Reduced Peak Height (Rpk) The top portion of the surface which will quickly be worn away when the engines begins to run

Industry RecommendationsGeneral Applications: Good Performance with Good Life Rpk: 8-12 micro-inch (
