Re: Stored Westerbeke 46
Adding Marvel will help to free up the rings. Injectors are basically nothing but high pressure check valves.(30 year diesel mech here) Soaking them could eliminate varnish that the fuel may have turned into. Most reputable marinas "pickle" engines that are known to be going into long term storage. This means they put additives in all areas,fuel, oil, & water. these additives are conducive to help in long term storage.Running the engine long enough for this additive to reach the injectors is the key.
