Miscellaneous Sealants – 2.5L NA Estimated reading: 2 minutes Contributors Overview This procedure outlines the recommended sealants for maintenance and repair of the Porsche 944 variants with an 8-valve engine configuration, covering model years 1982–1989. Proper sealant application is critical to prevent leaks, ensure component integrity, and maintain engine performance. This guide is tailored specifically for the 8-valve engine variants, focusing on components such as the oil pan, water pump, and camshaft assemblies. Note that pre-1985.5 models use steel control arms, while 1985.5–1989 models use alloy control arms, though sealants for control arm bushings are not typically required.
