Finally home. Check it out. It has a B but next to it not sure as if something fell off. There looks to be a change in color. Or maybe i'm just imagining.

It's a B. The space next to it has been machined flat and is where the original casting would have two different casting marks. I believe these older B blocks were common with the 2B block, but I am not sure. The post 1988 B blocks (which yours is definitely not) were common castings with the 11B. This casting is shown in a post quoted earlier in this thread.

I wouldn't be disappointed that it's a B and not a 3B, they are both ancient tractor engines and the difference in 'performance' between a 3.0 and a 3.4 is probably less important than how worn out the engine is. If it drives happily at 55 mph then it can't be too bad.

I believe that is a B. 3.0 litre 8 valve diesel. There should be a casting on the intake side of the engine, at the top of the block, under the #4 cylinder intake port. It's no younger than July 1988 and (less sure about this one) would say it is no older than 1984 or 1985.

You were right from the get go then.
 
This might be a pretty stupid question. But being a B engine, would i be able to add power steering to it? Would it be worth turboing it?
I would love for this car to be my daily driver, I don't want to travel at 85 or anything but, I definitely want to be able to hop on the freeway and not cause a traffic jam.
 
Power steering works fine. Turbo is not a good idea. The pistons do not have oilers like the 3B from what I understand. This is the biggest downside to the B

Not a stupid question. Have a search for BJ40 power steering kits.

People have mixed results when turbocharging the 3B, it needs to be a conservative tune as I understand. As Mitch said however, the B is even less suited than the 3B as it does not have piston cooling oil nozzles.

Out of interest, does your engine have a rotary or linear inkection pump?

Good point. My understanding is that only the 1988 onwards B engine (aka Bii) had nozzles. The OPs engine clearly pre-dates this.

My 1985 3B had oil nozzles.

My understanding is that all 3Bs have them. But I'm talking about the B specifically in the post you quote, not B Series engines in general.

What was a B engine doing in anything after 1988? They were phased out AFAIK much, much earlier.

They were in Dynas until the mid 1990s. But as a much improved Bii with monoblock, roller lifters, oil squirters etc. Same block as the 1988-on 11B.

Then, they weren't called B engines. I haven't found one listing showing a "B" engine in a Dyna that late.

This is a Bii block. Notice the painted-over oil nozzles and flat-top valve cover:

There's a thread in the disesl section by a guy with a Bii in a ToyoAce which is getting a turbo...

Me too actually. I didn't realise that the B engine had no oil nozzles until so late. I thought all B Series engine had them from the early 1980s when the 3B was launched.
 
Thanks for checking! That is indeed a rotary pump. This means the engine came from a JDM Dyna/ToyoAce truck. The pump has an idle-up actuator, meaning that the engine once had an AC compressor.

Man, i don't know well enough to be happy or bummed out just yet. Not really sure if I should swap it or keep it. I'll take any advice!

What is your primary concern... just more power? I'm swapping my B for a 13-BT for something with a bit more power, a bit more modern, and hopefully a bit less stinky! I have to stick with a diesel because of Cali. The 13-BT was a relatively painless swap for me because it is basically the direct replacement. One thing for you to consider is the transmission shaft, and I believe the bell housing too, is unique to the diesel engines, so swapping to a gas engine would require the trans too or at least a new input shaft with rebuild. I say enjoy it until it breaks and then decide.

Man, the sink is no joke!
I want this to be my daily driver. I'm planing on upgrading the tranny to the H55f, I hope I get a little more speed, but all in all the biggest issue for me is the 24V thing. It just seems to be harder to find parts and people who understand the system.
 
My B turned out to be a mark II B, these are characterised by rotary fuel pumps and on board vacuum pumps and 10 hole exhaust ( 1 and 4 have 3 holes) manifolds externally.
Internally they have 5 bearing camshafts and oil squirters and a few other thingy-ma-bobs.
I'm not sure if the original B had a rotary pump, so you may be lucky.
I had mine in a longwheel based land Rover and it did just fine especially with a ton and a half on Pommey drum brakes.
If it is a mk II and you want to turbo, then a 14BT manifold will fit,
My dream was to convert to an 11B by swapping fuel pump, head and pistons and then turboing it believing that direct injections turbo better. BUT then i got better and got a 76 Wagon with an HZ motor and never looked back.
Shout if you have the MK11 and need a manual.
