Omega General Help / High RPM sound
« on: 01 March 2019, 08:12:10 »
Hello,
3.0 litre Omega has developed this metallic rattling noice above 5000rpms. Oil changed at every 5 000-10 000km or after one year. 262 000km driven. Head gaskets changed at 220 000km and the heads were cleaned but not lifters. Lifters doesn't rattle even when started from -20degrees. Gearbox is fine and she has all the power she ever got.
Lifters or bearings or something else?
In two months it has been 4 years since last cambelt change, and at the moment 42 000 km with that belt, so there is a service coming anyway.
