Porsche 911 992 Timing Chain Malaysia — No IMS
911 992 uses timing chains — no scheduled replacement. The 992 eliminated the IMS bearing issue of M96 engines (996/997). Oil quality is still the single biggest chain longevity factor. RMS (rear main seal) is the residual oil sealing concern on 992 at 100,000+ km.
Porsche 911 992 Timing Chain — No IMS Issue
- 992 uses timing chain — no scheduled replacement
- IMS bearing failure was an M96 engine issue (996: 1997–2005, 997.1: 2005–2008) — 992 is NOT affected
- The 9A2 Evo engine in 992 has revised bearing design — IMS is a non-issue; focus on RMS and oil changes
- Key: keep oil clean and change on time — dirty oil degrades chain tensioners over time
