Re: cross index between Westerbeke 30 and ford Leyland diesel en

The Leyland 1500 diesel was marinised by several companies in the UK and many are still in use today. The main mariniser was Thornycroft which was then part of Leyland but is now owned by an Indian company. They can supply many new parts, I fitted a new freshwater pump on mine and converted the CAV oil filter to spin on last year, with parts from them. They will ship worldwide at sensible prices.

The 1500 is Thornycroft T90

ASAP in the UK also supply many parts at sensible prices Marine, Automotive, and Industrial Parts and Spares - A.S.A.P Supplies

Parts up to complete engines are often available on Ebay UK, and there are a few other companies selling parts both for marine versions and automotive versions. Try googling for BMC 1500 diesel.

Hi Rob-

The Rocker Cover gasket was sourced directly from a Westerbeke Parts Supply dealer in the Bay Area called "The Outboard Motor Shop" in Oakland, CA.

Thermostat housing gasket came from JC Whitney. Really. 2nd time around.
I broke the first one, which was $25 from Westerbeke.

Fuel Filters I usually obtain from the Perkins suppliers, and the fuel pump gasket came from Bosch.

Good Luck!

TheChesterP All;

Ian is your guy on this. He introduced me to the fact the the 1500B block is essentially the diesel version of the gas MG block. It is NOT a ford. It is British Leyland through and through. I was recently able to purchase reasonably priced gasket from a British car parts supply house for my W30.

And... this is important: The W30 is NOT the 4-91 in any way shape or form. The W30 replaced the 4-91. I recently rebuilt mine. Photos are on flickr dot com slash chuckbullett. It is a sweet sounding engine when you have everything dialed-in.

IanMcGoo22 Hi Marc,
I know this is an old post but I just joined and saw it, so I thought I'd write. I'm a British car enthusiast and I know the British Leyland B-series engines well. So, if you need any help identifying or finding parts, send me a message and I'll try to help.
A lot of the smaller parts, gaskets, etc, on your engine will be common to the gas versions used in cars too. Any MG sports car specialist could help you out.
Best regards,

Are you sure the W30 and is based on a Ford Leyland? I have read that it is based on a British Leyland. Do you know if the Ford and the British Leylands are different or the same?

You might just call up the Westerbeke folks and ask them about the origin of your engine. I''ve found them pretty forthcoming on the origins of a given, now dated engine. To start, you can visit them at for #s & names of key people.
