Buy-risk rundown
| Issue | Symptom | How to check | Typical cost (as of Nov 2026) |
|---|---|---|---|
| Dual VANOS seals / solenoids | CEL, lost low-end power, cold-start rattle, rough idle | Scan for VANOS codes; listen cold; ask for seal rebuild (not just full unit swap) | Dealer unit swap historically >$4,500; independent seal rebuild is the usual path — shop total not yet verified [1][2] |
| Plastic timing-chain guides | Rattle from the front; worst case jumped timing | Ask for guide/chain service records | Not yet verified as a standalone shop price [1][3] |
| Rod bearing wear (less common than S85, still serious) | Knock under load; copper in oil | Oil analysis; listen under load; ask about preventive work | Catch-it-early bearing job ~$4,000 class; scored crank much more [3][4] |
| Valve-cover / oil leaks | Oil smell, wet covers | Visual inspection | Common with age; cost not yet verified [3] |
| Clutch wear | Slip at highway pull | Test-drive engagement | Not yet verified [2] |
