No car stated. (of truck if is one)
no year,
no model car, or truck.
no country stated.
you do know that all online data is INDEXed by that , right.
starting with YEAR.
so my challenge is to look it up with no input from you.
this is a USA forum and our isuzu dealers sell only these huge NPR heavy trucks hear.

but if you google that engine you might luck out or get wrong info.
why trust the whole engine on internet rumor, is my answer.

here ill type that for you..

SOURCE: need valve lash specs for 95 escort 1.9l

Valve stem-to-valve rocker arm clearance should be within specification with the valve tappet completely collapsed.
The collapsed valve tappet gap, when the cylinder head is on base circle, should be as follows:

    • Minimum: 0mm (0.000 inch)
    • Nominal: 2.2mm (0.087 inch)
    • Maximum: 4.5mm (0.177 inch)

    its used on NPR large trucks, this is not a truck forum here.

    lash, try google yet or the isuzu dealer?
    0.14mm (take this with grain of salt, its rumor)

    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.

    i guess you think all engines work same in all countries and years?
    wow.

    did you ask ISUZU first? that be first. right, a book on your heavy truck.

    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.

    How to adjust valve lash on a 1990 Geo Storm


    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.

    Knocking in the motor


    Hi there:

    Check this information about "engine noses"...

    ENGINE CLICKING NOISES
    A clicking or tapping noise that gets louder when you rev the engine is probably "tappet" or upper valvetrain noise caused by one of several things: low oil pressure, excessive valve lash, or worn or damaged parts.

    First, check the engine dipstick to see if the oil level is low. If low, add oil to bring it back up to the full mark. Is the engine still noisy? Check your oil pressure. A low gauge reading (or oil warning light) would indicate a serious internal engine problem that is preventing normal oil pressure from reaching the upper valvetrain components. The cause might be a worn or damaged oil pump, a clogged oil pump pickup screen or a plugged up oil filter. Using too thick a viscosity of motor oil during cold weather can also slow down the flow of oil to the upper valvetrain, causing noise and wear.

    COLLAPSED LIFTER NOISE
    Worn, leaky or dirty lifters can also cause valvetrain noise. If oil delivery is restricted to the lifters (plugged oil galley or low oil pressure), the lifters won't "pump up" to take up the normal slack in the valvetrain. A "collapsed" lifter will then allow excessive valve lash and noise.

    VALVE LASH NOISE
    If you can rule out lubrication-related problems as a cause, the next step would be to remove the valve cover(s) and check valve lash. On older import engines, mechanical lifters require periodic valve lash adjustments (typically every 30,000 miles). Too much space between the tips of the rocker arms and valve stems can make the valvetrain noisy -- and possibly cause accelerated wear of both parts.

    To measure (and adjust) valve lash, you need a feeler gauge. The gauge is slid between the tip of the valve stem and rocker arm (or the cam follower or the cam itself on overhead cam engines) when the piston is at top dead center (valve fully closed). Refer to a manual for the specified lash and adjustment procedure. Also, note whether the lash spec is for a hot or cold engine (this makes a big difference!).

    On engines with hydraulic lifters, oil pressure pumps up the lifters when the engine is running to maintain zero lash in the valvetrain. This results in quiet operation. So if the rocker arms are clattering, it tells you something is amiss (bad lifter or worn or damaged parts) or the rocker arms need adjusting.

    DAMAGED ENGINE PARTS NOISE
    Inspect the valvetrain components. Excessive wear on the ends of the rocker arms, cam followers (overhead cam engines) and/or valve stems can open up the valve lash and cause noise. So too can a bent pushrod or a broken valve spring.

    RAPPING OR DEEP KNOCKING ENGINE SOUND
    Usually bad news. A deep rapping noise from the engine is usually "rod knock," a condition brought on by extreme bearing wear or damage. If the rod bearings are worn or loose enough to make a dull, hammering noise, you're driving on borrowed time. Sooner or later one of the bearings will fail, and when it does one of two things will happen: the bearing will seize and lock up the engine, or it will attempt to seize and break a rod. Either way your engine will suffer major damage and have to be rebuilt or replaced.

    Bearing noise is not unusual in high mileage engines as well as those that have been neglected and have not had the oil and filter changed regularly. It can also be caused by low oil pressure, using too light a viscosity oil, oil breakdown, dirty oil or dirt in the crankcase, excessive blowby from worn rings and/or cylinders (gasoline dilutes and thins the oil), incorrect engine assembly (bearings too loose), loose or broken connecting rod bolts, or abusive driving.

    Bearing wear can be checked by dropping the oil pan and inspecting the rod and main bearings. If the bearings are badly worn, damaged or loose, replacing the bearings may buy you some time. But if the bearings are badly worn or damaged, the crankshaft will probably have to be resurfaced - which means a complete engine overhaul or replacing the engine is the vehicle is worth the expense.

    ENGINE PINGS OR KNOCKS WHEN ACCELERATING
    The cause here may be Spark Knock (Detonation) caused by an inoperative EGR valve, overadvanced ignition timing, engine overheating, carbon buildup in the combustion chambers, or low octane fuel.

    Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

    Thank you for using FixYa, have a nice day.
