      Bob,
      a few years ago you stated you replaced your rear main bearing seal to fix an oil leak. was it successful? is it worth doing that job or should I leave well enough alone? I have replace the fuel tank , so I might as will get it done at this time. If thought it was going to be worth it

      Hi Alan,

      It wasn’t me with the rear main seal. I replaced the oil sender unit and
      immediately pumped almost all my oil into the bilge.

      Use Teflon tape on that baby.

      it may have been Pete Dubler.

      Pardon the brevity. I’m typing this on my phone and I hate typing on my
      phone.

      Alan-
      I replaced it on our W-58. We were leaking pretty bad, to the point that oil was accumulating in the bellhousing, getting thrown around by the flywheel and gumming up the starter.
      I’d say it depends on how bad it’s leaking, bearing in mind that it won’t cure itself.
      We used the standard seal from Westerbeke which is the same as on the W-40. Not too bad a job it you are going to move the engine anyway, and remove the transmission and starter. Then you need to remove the flywheel to get to the seal. Have not had a problen since.
      Foley Engines has a special seal for more money for the Perkins 4108 that should fit the W-58. We didn’t use it, but it looked interesting. I’ve not shopped at Foley, so I can’t comment on their customer service, but others have strong views.

      Thanks Quent.
      I saw the one from foley, it did look interesting. I believe that seal is no longer available but they have a cross-reference for a Perkins part number but I can’t find it anyplace. I’ll call around tomorrow.

      Hi Alan,

      If you have any trouble finding the seal just remember that the W58 is the same engine as the Perkins 4.154 series 200.

      I was told that the W58 was a Mazda industrial engine and Ihave bought parts in Trinidad using that information. Jim Roberts-Revery

      Hi Jim,

      I don’t doubt that.  Perkins, like Westerbeke does not build blocks but buys them from someone, marinizes them, paints them blue (or red for Westerbeke) and sells them as their own.   I have heard that Perkins uses Mazda blocks for a lot of their engines.   I just tracked the W58 back to a corresponding Perkins engine but not back to the original producer of the block.

      In the states I found that the Perkins version was used in a lot of heavy equipment like Bobcats, tractors, and such and if you order parts from that channel instead of Westerbeke marine you can save big.

      Any chance you know what Mazda block is used?

      Thanks

      It’s the same block as the one used in the Mazda B200 diesel pickup truck
      that was never imported.
