Anyone know what might cause a growling sound -- sort of a deep rattle -- on a '98 ES? It's particularly noticable when on cold start and reduces somewhat as the engine warms up. This has been going on forever so surely there's a TSB about it?

Thanks

not uncommon in LH engines. the oil drains slowly backwards when the engine isn't on and the loud knocking goes away as soon as all the nooks and crannies get filled up with oil again. if it lasts more than 5-10 seconds it's worth more investigation, otherwise i wouldn't worry about it.
