best is to by the shop manual not use internet rumors

Injection pump timing is timing the fuel spraying into the cylinder to the piston as it nears top dead center. It is a precise timing, to soon or to late and it won't run, if its just close and runs it can burn valves and holes in pistons. The fuel must be injected in at the correct time. That's why the pump has to be timed.

http://www.answers.com/Q/What_are_the_valve_clearance_of_4BE1_isuzu_engine

id never use internet rumors to build engines
we dont have this engine here, I think,... but id have to drive to ISUZU and ask them and buy the book.


the 4BE1 is a 3.6L direct injection engine. It replaced the 4BC2 in Isuzu NPR's from 1987- non turbo, VE rotary injection pump or Zexel/Diesel Kiki A-type injection pump. Bore and stroke are both 105 mm. Power ratings in the last versions (NKR300)are 74 kW (100 SAE HP) at 3,500 rpm and 242 Nm at 2000 rpm.

4bc2 . ELF truck?
e 4BC2 is a 3.3 L direct injection diesel (otherwise the same as the 4BC1) sold in the Isuzu ELF and NPR trucks from 1982 to 1987

its an Isuzu engine.
there are 3 engines.
4XE1, SOHC 1.6L (base)12valves
4XE1, DOHC , 1.6L same as above but now with 16valves.
4XE1, DOHC, 1.8L bends valves if belt snaps...
note the bad idea of ISUZU calling all 3 engine same name.
a horrid idea.
which one? the second was in USA and Canada only.
the second one was offered as the GSI. is yours that?

so I will attempt to guess for you, its the base engine.
(odds of coin toss)
toss #2, USA, SOHC
guess 3: did a new belt and want to do lash next. Cam belt>
No job stated so i guess 3 times.
Just lash.
SOHC 1.6L only (FSM book quote)
Check the valve lash between the rocker arm and valve stem on both the intake and exhaust valves on the number 1 cylinder, the intake valve(s) on the number 2 cylinder and the exhaust valve on the number 3 cylinder. If the valve lash on the intake valves is not 0.006 in. (0.15mm), adjust the valve lash. If the valve lash on the exhaust valve is not 0.010 in. (0.25mm), adjust the valve lash.

1.6L twin cam has shims.
1.8L has HLA , no lash to set.

HLA= Hydraulic Lash adjusters.

I posted this before, search for it. Im only doing 1 engine.

Don't have this.
