4B engine glowing system problem (1 Viewer)

[ballemann]

Hi, I bought a Landcruiser BJ40 (1980) in Chile and wants to travel through south america.
They previous owner changed the engine from the 6 cylinder petrol to a 4 cylinder diesel a few years ago. On the sign on the motor is written: B 700 and 4B. I couldn't find anything from a 4B engine in a forum! On the engine itself is written BU, what in my opinion means that this is a engine from Dyna. In the engine registration forms of the chilenan gouvenement is written, that the engine has a displacement of 3956cc. The engine is equiped with the rotary injection pump which looks similar to the one of the 3B-II engine.
My main porblem is the glowing system. The temperature sensor is not conected and I have no plan how to conect it. Of course it is not similar to the system normally used for the B engines...

Congrats on the new rig and welcome to MUD. Love the idea of touring with the cruiser--you should try to check out the series in the Toyota Trails magazine about the South Africans in their troopy, might give you some ideas.

I would repost this over in the Int'l Cruizers, Diesel, 24v tech section, or maybe one of the Mods will move it for you...

If the model # on the VIN plate says BJ40 as you say, then it has been a diesel all along, maybe with a 2F engine somewhere along the way.

I could not find a 4B listed in the cruiser FAQ http://birfield.com/modules.php?name=TLCFAQ&p=/~ramullen/FAQ/TEXT/05-04.html

If a Toyota engine, maybe an indirect injected version of the 14B?

What are your symptoms re: the glow system? Hard cold starts? Have you hooked up a voltmeter to your plugs to see what's going on?

4B, it could be a odd toyota motor, a SA specific motor? The 14B is 3660cc, the closest I know of to that cc in 4 cylinder is a 1W at 4006 cc, also shown as a W04D which has to be the Hino 4 cyl. in their cab-overs.

If it is a 1980 BJ40, then it should have the "B" engine in it.

I can find no reference to 3956cc for a LandCruiser engine. 3955 is the closest...which is the 3FE.

Best bet to see what was in the truck from the factory is to post up the build plate VIN from the plaque on the firewall, engine side.

BU certainly indicates Dyna. Check this out: http://toyotadyna.tripod.com/id16.html

Look for your main glow plug relay in the engine bay, and wire a momentary switch from the dash to the relay. This way you will control how much glow is put to the plugs. Read this: https://forum.ih8mud.com/showthread.php?t=38416 and look at post #22.

There is a Cummins 4B which is a 3.9L engine, but it looks nothing like it.

Ya, and the thermostat housing points off to the right, like the manual steering "B"s, but has the rad cap on the housing, unlike the manual LC "B" engines I have seen. The Dyna's did head off to the right however, ala this page that details a 14B-T swap. http://www.gscruiserparts.com/3F_to_14BT_in_FJ70.html

The 14B-T has a different looking valve cover then the one in the pic. It it more rounded like the early "B"'s. I wonder....

Got any pics of a 14B in your archives Dave?

ballemann, got any pictures of the injection nozzle body area? Do they look like direct injection nozzles or indirect injection nozzles.

Either way...go to a manual glow system...

The car was original equiped with a 2F engine and swaped to the diesel eingine in 98. The only useful information of the engine is marked on the head cover... with B700 and 4B... And some Japanese signs...
However, the problem I have is a bit different. The glowing timer is not correctely wired and runs all the time for exact 24 seconds and is not lowering the glowing time when the engine is hot. So far the engine starts well as long the engine is cool. When i drive for a while and stop for a couple of minutes the eingine does not start with the glowing time of 24 seconds, but if i go shorter it starts without a problem - but you need to be guite precice with the glowing time... I checked the voltage at the plugs and also the resistance at them... looks perfect - all in the specs of the 3B 12V engine...
Additionly the engine starts either immediately or will not start at all, what is in my opinion quite unusal for a diesel eingine.
I thought i can solve this problem with the conection of the water temperature sensor, but I am really not sure this alone helps. The whole glowing system timing and relais is the grey box in pic. 3. I opend it and it looks guite complicated... more like a small computer. and i do not like to conect it without a idea what I do... When I change to the manual timing system, it will not solve my timing problem... Any idea where the problem can come from??
Thanks...

Get rid of the whole box. Buy a simple relay rated for required amps. Put in a push button on the dash. Simple is the key.

Glow for however long you feel is correct.

Timers always suck.

As far as sometimes it doesn't start. Different problem in my opinion. My guess is that your edic system is not going to run or overiject.

Next time it doesn't start pop the hood and have some one crank while you watch the edic arm for aft movement.

Where in Chile are you? I was in La Serena last May. Beautiful area. I went flying in Los Andes.

Cheers.

My bad, you may not have an EDIC system. Is it VSV operated. Greg B can help with that troubleshooting.

Cheers
