CATERPILLAR-3034-VALVE-OIL-SEAL

192-6335 is a valve stem oil seal for the Caterpillar 3034, fitted at the top of each valve guide to control how much oil is allowed to lubricate the valve stem without letting excess oil be drawn down into the cylinder on the intake stroke. These seals harden with age and heat exposure well before most other top-end components wear out, and blue smoke on cold start-up that clears after a few seconds is the classic sign they need replacing.
