Good info on B diesel heads
I search for a new cylinder head for my old B diesel (March 1980). These heads are very rare now. I try to understand the options. Official replacement for 11101-59045 is 11101-59046 (not available). 3B head is created for large cylinders - I dislike this option. I made a small comparison of...

Toyota diesel glow plug compression tester fitting
Diesel oil weight recommendation from the manual
Valve adjustment 3b.
3B timing
3b hard starts, two simple tests and one harder one.
1 - pull the buss bar and wire off the glow plugs. get a volt meter put it to the ohm setting put one lead on the block the other to each of the tops of the glow plugs. Make sure they all are near the same resistance to the block and none are open.
2 - before hooking the wire back up to the buss bar make sure it’s not touching anything put you meter to volts dc. Put one lead to the block and one to the glow plug common wire. Make sure there is 12vdc for at least 20 seconds cold (on 24vdc system less time is needed)
3 - Assuming 1 and 2 check out ok. Your not going to like this but you need a compression test. You will need a compression gauge that will go up to 500psi. More than likely your compression is low and even lower cold.
Other possible issues.
You could have air getting into one of your injector lines as the motor cools down and the fuel contracts it can pull some air in. Only effects the first start and acts like it’s missing till the air bubble works it’s way threw.
The edic also adds extra fuel while cranking to help with starting. The connecting rod can vibrate out of adjustment. While cranking check to make sure the swing arm on the injection pump is pulled back by the connecting rod towards the firewall. Once started it should sit loosely in the middle of its swing.
Slow cranking from weak batteries or bad connections will crank and start the motor but not give it that quick compression that will help cold diesel explode.
DIESEL SMOKE COLOUR
Basically there are 3 types of smoke emitted from a diesel engine: black, blue and white.
Black smoke:
Black smoke is the most common emitted from diesel engines and indicates incomplete combustion of the fuel. Black smoke causes can vary widely and include ..
· Incorrect fuel injection timing
· Dirty or worn fuel injectors
· Over fuelling
· Faulty turbocharger, or turbo lag
· Faulty or dirty exhaust gas recycling (EGR) system
· Incorrect valve clearance
· Incorrect fuel to air ratio
· Dirty or restricted air cleaner systems
· Over loading the engine
· Poor fuel quality
· Cool operating temperatures
· High altitude operation
· Excessive carbon build-up in combustion and exhaust spaces
Black smoke can occur across the entire operating range, but is usually worst under full power, or during the lag before the turbocharger boosts air supply to match the fuel usage such as in the early stages of acceleration and during gear changes. Moderate turbo lag smoke is acceptable; otherwise black smoke should be hardly visible in a correctly running engine.
Blue smoke:
Blue smoke is caused by engine lubricating oil burning. The oil can enter the combustion chamber from several sources including:
· Worn valve guides, or seals
· Cylinder &/or piston ring wear
· Cylinder glaze
· Piston ring sticking
· Incorrect grade of oil .. too thin and getting past rings, or valves guides
· Fuel dilution of the oil, making it too thin.
Blue smoke is often evident at cold start, which can reflect reduced oil control due to carbon fouling deposits around the piston rings and/or cylinder glaze. Blue smoke should not be evident at any stage.
An engine may burn oil without the evidence of blue smoke, because good compression burns oil quite cleanly, however, it is not acceptable for any new engine, or engine in good internal condition to burn large amounts of lubricating oil.
White smoke:
White smoke is caused by raw, un-burnt fuel passing into the exhaust stream. Common causes include:
· Incorrect fuel injection timing
· Defective fuel injectors
· Low cylinder compression
Low cylinder compression may be caused by leaking valves, sticking piston rings, ring wear, cylinder wear, or cylinder glaze. When white smoke occurs at cold start and then disappears as the engine warms up, the most common causes are fouling deposits around piston rings and/or cylinder glazing.
Continuous evidence of white smoke indicates a mechanical defect, or incorrect fuel timing.
