Jerry I was thinking the same exact thing you were. Im just stumped over the engine in the pics and would like to see which series it is. BTW found this group while searching the web http://www.isuzupup.com/forum/

I HAVE NEVER SAW ONE WITH THAT DESIGN VLV CVR , IF IT IS NOT AN INDUSTRIAL ENG , AND APPARENTLY ISNT , IT MUST HAVE BEEN MADE BEFORE ABOUT 1980 OR EARLIER ,THAT IS WHERE ALL MY INFO STARTS FOR ALL THE ENGS THAT WERE AVAILABLE IN THE U.S. JERRY

Jerry thats what i was thinking myself but i did find this on an Austrailian Rover site.

1981: An Isuzu 4BD1 3.9-litre 4-cylinder diesel engine was a factory fitted option in Australia.

If I were a betting man I would also say that the engine was produced on or before 1980 because I have done quite a bit of research and have found no type of picture to confirm the engine.

Is this the engine? http://i2.ebayimg.com/02/i/07/93/52/8f_1.JPG

Just fond something else WANTED!! 1985 - 1988 Trayback 110 with 3.9L diesel isuzu engine

--------------------------------------------------------------------------------

Posting this on the Australia list as well, I'm after a Landrover 110 trayback (the ones that are 120 inches long) with a 3.9L diesel isuzu engine in them. Any condition. Anywhere in Eastern Australia, or NT. If you know of one with another engine please let me know also.
Thanks! Happy driving.....

THAT PIX ON YOUR LAST POST SURE LOOKS LIKE AN OLDER MODEL 4BD1 JERRY

That's not a 4B series engine, it has similarites to the 4B series but the throttled air intake is a major departure.

In NZ we had Isuzu trucks in the early 80's which were badged "Isuzu-Bedford", we're talking pre-runner to the NPR series of around 1985.
A neighbour had one which had a 3.9 litre engine with a lower output than the 3.3L 4BC2 which came in the first NPR's.

The truck model may have been a K20 or something similar. The Isuzu parts dealer had a wall poster showing the trucks from way back then, but I have moved and can't refer to it.

Regardless, if that rocker cover will fit my 4BD1T then I want one. <img src="/forums/images/graemlins/smile.gif" alt="" />

HI DOUGAL I THINK HE WAS REFERING TO THE POST JUST BEFORE MY LAST ONE OF THE DSL WITH THE SHEET METAL VLV CVR , THAT IS THE ONE THAT LOOKS LIKE THE OLDER MODEL 4BD1 NOT THE ONE WITH THE ALUMINUM VLV CVR , I NEVER SAW A 4BD1 WITH T HE ALUMINUM CVR , WHAT WE GOT HERE IN THE STATES ON THE 4BD1 ENG EVEN THE OLD ONES IN THE KS22 TRUCKS HAD TWO CVRS ONE ON TOP OF THE OTHER WITH AN INSULATING PAD BETWEEN THEM TO TRY AND QUITEN THEM DOWN SOME .. JERRY

Thanks Jerry, I didn't realise the steel rocker covers were two pieces. I'll try to pull mine apart for a look.

I think my 4BD1T is around 85 vintage, japanese spec with the IHI turbo otherwise they all seem to look the same.

Hodgoes did you ever find out what series the engine is?

Incase someone is still going with this is there any chance the engine is from the 4F*1 series?
It was in gemini's/imarks shuttle/fargo vans and mayb some pickups.
