Isuzu kb 260 petrol 4ze1 motor head and block settings

The correct head and block settings for an Isuzu KB 260 4ZE1 petrol engine will depend on the specific model and year of your vehicle. It is generally recommended to refer to the manufacturer's specifications or a repair manual for the specific head and block torque settings for your engine.
In general, the head bolts on an Isuzu 4ZE1 engine should be tightened in a specific sequence and to a specific torque specification. The block bolts should also be tightened in a specific sequence and to a specific torque specification.
It is important to follow the manufacturer's specifications and torque the head and block bolts to the correct specification to ensure proper engine function and to prevent damage. If you are unsure about the correct head and block settings for your engine, it is recommended to seek the assistance of a professional mechanic or refer to the manufacturer's specifications.

I am leaking coolant from the rear of the engine. Got under and was leaking by oilpan but could not see directly due to skid plates and oil etc. any ideas?? only leaks when the engine is running.

Had the same problem. Someone did work on the heads and did a lame job on the water crossover tube that connects to both heads. I solved the problem by replacing the 2 gaskets instead of the silicon they used. The bolts that hold the crossover tube on are to say the least a pain in the *** to get to. Plan on taking the plenum off.

Izuzu 1992 model. can not start

If the smoke is more of a white then the piston rings a worn out and the engine would require a complete overhaul. If the smoke has a bluish tinge to it, then it is most likely a blown head gasket which can be replaced by removing the head and putting on a new gasket. But before you preform repairs, has the vehicle ever been over heated, if so it is possible the a cylinder wall has a whole in it which would require a new engine.

1992 Toyota Previa van,Oil dripping onto exhaust manifold, replace head gasket? need a free manual!

The toyota previa uses a formed silicone gasket for the valve cover and the cover is held in place by metric shoulder bolts ( 10mm). The valve gasket leaks because you can't get enough preload on the bolts to re-seat the old gasket when it gets old and shrinks. The shoulder bolts only allow you to tighten the gasket enough to seat the shoulder on the bolt. If you continue to torque down the suspected bolts, you will snap the bolt off ( don't ask me how I know this ). You can either 1.)replace the old gasket with a new one or 2.) remove the existing bolts around the leak area and put in new metric bolts that do not have a shoulder. You may want to put in a small sleeve into the existing bolt hole but shorter than the thickness of the valve cover to account for the smaller diameter bolt. You can now torque down the bolt and get enough preload to seal the valve cover without removing the old gasket. Make sure you use a torque wrench ( in-lbs) or be very careful not to snap these small valve cover bolts.

Hello, it is not essential to use new bolts on the 4ZE1 engine. Those bolts can be re-used.

SOURCE: Head bolt torque specs needed for 96 tbird 3.8

Head bolts are torque to yeild so you MUST use new bolts.
Tighten cylinder head retaining bolts in numerical sequence in three steps as follows:

20 Nm (15 lb-ft).

40 Nm (30 lb-ft).

50 Nm (37 lb-ft)

Loosen retaining bolts one at a time two to three revolutions and retighten as follows:

Long bolts:

Tighten to 40-50 Nm (30-37 lb-ft).
Rotate an additional 175-185 degrees.
Go to next bolt in sequence.

Short Bolts:

Tighten to 20-30 Nm (15-22 lb-ft).
Rotate an additional 175-185 degrees.
Go to next bolt in sequence.

SOURCE: The new head gasket manufacturer mandates new head

Yep. The had bolts stretch when torqued and stay that way when released making retorquing precarious and not right. When you take one of the new bolts that you get and put it next to a old one you will see what I mean. All head bolts are this way now once and done. Now if this is for a cheating ex girlfriend than you can reuse the old ones.
