[QUOTE="Rednaxs60, post: 218079, member: 4617"] Checked the compression and oil wiper ring thickness. OEM 6 at 1.16 mm, 2 at 1.17 mm. All aftermarket at 1.16 mm. The new rings have a lot more spring in them. Here are pics of the compression and oil wiper rings. The aftermarket rings are placed on top of the OEM rings. The arrow points to the shiny area from the OEM rings under the aftermarket rings: Compression Ring:[ATTACH type="full" alt="Compression ring.jpg"]20194._xfImport[/ATTACH]Oil wiper ring:[ATTACH type="full" alt="Oil Wiper Ring.jpg"]20195._xfImport[/ATTACH] The OEM rings have compressed and have a "set" that cannot be removed or changed no matter how much the engine is used. Think it was a good idea to hone the cylinders and replace the rings. Will have to buy some standard mineral oil for the break in period, then switch back to synthetic. Probably do 3000 to 5000 Kms with mineral oil. [/QUOTE]
