Installation of compression rings
There are marks on the rings (1(2)T or 1(2)N for 4-cylinder engines and 1(2)R or T1 (t2) for V6).
Installation
1. Before installing new piston rings, sort the rings and check the joint clearance. To do this, push the ring with the piston bottom. The ring should be at the bottom of the cylinder, in a position corresponding to the bottom dead center.
2. Measure the gap in the joints. If the gap is too small, replace the ring; filing the ends is prohibited.
3. Install the rings on the piston, starting with the oil scraper. Install the spacer/expander in the groove.
4. Make sure the pin is present (if provided) and install the lower and upper discs. When installing oil scraper discs, do not use a device for putting on rings, as they may break.
5. Make sure the upper and lower discs rotate freely in the groove. Install the middle and upper rings (see Fig. Installation of compression rings). The marks on the rings should face the piston bottom. Install the rings on the remaining pistons.
