Replaces part number 52-032-13-S. A hard or split seal lets oil run down the valve stem into the cylinder, which shows as blue smoke at start-up or after idling and an oily plug. Check the valve guides for wear before fitting, since a seal will not control oil past a worn guide. Oil the stems, push the seals on square without catching the lips on the keeper grooves, and use new head gaskets when the heads go back on.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eTWO INTAKE VALVE STEM SEALS - Replaces 52-032-13-S, also written 52 032 13-S.
