Hi afvazquez,

Did you rebuild or just replace the engine? If it was a do it yourself rebuild then I'd think that something went wrong with the assembly....If its a second hand, or alternatively a rebuilt engine, by some one-else, that's where I'd think the fault is....By the way, did you get rotation on the engine before putting it into the vehicle....if you tried it then and it did turn, pull it out again,as I believe you may have a problem with the clutch assembly, or in the case of an auto, if the tourque converter was not fitted correctly into the box you may have damaged the pump in the box and sometimes that will cause the engine to seem as though it's siezed....let us have more info on your problem, I'm sure we'll be able to help you more than I have....

Best regards

Where is the EGR valve located?


Doesn't have or need an EGR valve it has Camshaft Position (CMP) Actuator System
The camshaft position (CMP) actuator system is an electro-hydraulic operated device used for a variety of engine performance and operational enhancements. These enhancements include lower emission output through exhaust gas dilution of the intake charge in the combustion chamber, a broader engine torque range, and improved fuel economy. The CMP actuator system accomplishes this by changing the angle or timing of the camshaft relative to the crankshaft position. The CMP actuator simply allows earlier or later intake and exhaust valve opening during the four stroke engine cycle. The CMP actuator cannot vary the duration of valve opening, or the valve lift.
During engine OFF, engine idling conditions, and engine shutdown, the camshaft actuator is held in the park position. Internal to the CMP actuator assembly is a return spring and a locking pin. During non-phasing modes of the camshaft, the return spring rotates the camshaft back to the park position, and the locking pin retains the CMP actuator sprocket to the camshaft. The park position for the CMP actuator and camshaft is 8.5 degrees before top dead center (BTDC), which is equal to 17 crankshaft degrees BTDC. The engine control module (ECM) can only command the CMP actuator to retard the valve timing from the park position, or advance the valve timing back to the park position. The total range of valve timing authority is approximately 20 degrees of camshaft rotation, which is equal to 40 degrees of crankshaft rotation.
CMP Actuator System Operation
The camshaft position (CMP) actuator system is controlled by the engine control module (ECM). The ECM sends a pulse width modulated 12-volt signal to a CMP actuator solenoid to control the amount of pressurized engine oil, into the CMP actuator. To regulate the pressurized engine oil into the CMP actuator, the solenoid uses electromagnetic force on the solenoid pintle to pulse the oil control spool valve. The pressurized engine oil is sent to unseat the locking pin, and to the vane and rotor assembly of the CMP actuator, to either retard or advance the valve timing. The ECM will control the amount of ON time applied to the solenoid.

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.

I recenly repair a valve problem and engine runs smooth and all of a suden it jams...stop rotating.


Hi!!
Make sure the valve locks (keepers) did not come off and the spring retainer is in place. If any of this happened, the loose valve will cause the engine to seize.
Good Luck!! A HELPFUL - 4 THUMBS - rating for this solution would be greatly appreciated. Thank you for using FixYa.

I need the timing points for a lincoln ls 2000 with a 3.9


Hello

248015_84785203_1.gif


CAUTION:Rotating the crankshaft in a counterclockwise direction may cause engine damage. Crankshaft journals are directionally machined. Rotating the crankshaft counterclockwise can raise burrs on bearing surfaces, reducing engine life. Verify that the crankshaft keyway is in the nine o'clock position.

248015_84785204_1.gif

CAUTION:The crankshaft keyway must remain in the nine o'clock position until the cams are located, or damage to the valves may occur. Rotate the LH and RH intake and exhaust camshafts to locate them in their neutral positions.

I replaced the lifters in my 2000 galant 2.4 L and i need to know what to torque the rocker arm shafts to.


1.5 and 1.8 engines:
* Install the rocker arm and shaft assemblies. Tighten the rocker arm shaft retainer bolts to 23 ft. lbs. (32 Nm).

* Check valve adjustment and install the valve cover. Tighten the valve cover bolts to 16 inch lbs. (1.8 Nm) for the 1.5L engine or to 29 inch lbs. (3.3 Nm) for the 1.8L engine.



2.0 engine
* Lubricate the rocker shaft with clean engine oil and install the rockers and springs in their proper places.

* Install the rocker shaft assemblies on the engine. Tighten the bolts gradually and evenly to 21-25 ft. lbs. (29-35 Nm).



2.4 engine

Fig. Rocker arm shafts and components-2.4L engine



* Fit the rocker shaft springs from above and position them so that they are at right angles to the plug side. Install the rocker springs before installing the exhaust side rocker shaft and rocker arm assembly.

* Install the exhaust side rocker shaft assembly in the engine. Tighten the rocker shaft mounting bolts gradually and evenly to 23 ft. lbs. (32 Nm).
* Remove the lash adjuster retaining tools.
* Install the rocker cover and tighten the mounting bolts to 30 inch lbs. (3 Nm).

* Reinstall the spark plug wires to the spark plugs.



Hope helps.

Four cylinder feels like it is only hitting on three


you may have sticking valve or a weak or broken valve spring sometimes an exhaust valve rotator , it maybe that the # 1 cylinder exhaust valve is slightly bent and when it rotates to a certain spot it hangs slightly... requires inspection for confirmation, due a compression test or a cylinder leakdown % test...

Oil on sprark plugs


  1. Disconnect the negative battery terminal.
  2. Remove the valve cover, using the proper procedures.
  3. Remove the camshaft, shims and rockers, if equipped, using the proper procedures.
  4. Remove the spark plugs.
  5. Rotate the engine to Top Dead Center (TDC) for each cylinder's seals that are being replaced; e.g., if replacing the No. 2 cylinder valve seals, have the No. 2 cylinder at TDC. Use a coat hanger put down into the cylinder to determine when it is at TDC.
  6. Attach a fixture at the flywheel or the front of the engine to prevent the engine from rotating. Make sure the fixture damages no components.
  7. Thread an adapter into the spark plug holes that can be hooked up to a shop compressor air hose.
  8. Apply 90 psi of shop compressor air to the adapter hose. This is done to keep the valves from dropping down into the cylinder when the valve springs are removed.
CAUTIONTo avoid personal injury, wear eye and ear protection. Keep hands and clothing away from engine parts that rotate, in case the engine does rotate from the cylinder air pressure.
  1. With the cylinder under pressure, remove the valve spring retainer and the spring, using a spring compressor tool. Hitting the spring retainer with a soft hammer may help loosen the valve keepers, if the keeper will not move downward when trying to compress the spring.
  2. With the valve spring removed, remove the oil seal.
To Install:
  1. Install a new seal, using Toyota Special Service Tool (SST) 09201-41020, or equivalent.
  2. Reinstall the valve springs (See Valves).
  3. Release the air pressure and reverse the removal procedures to complete installation.
  4. Connect the negative battery terminal, start the engine and check for leaks.

How do i replace the pcv valve on a 2000 explorer xlt v6 sohc?


On the passenger side of the intake manifold, coming off the bottom about the center of the engine front to back, you'll feel a hose that comes off a nipple. That hose makes a 90 degree bend and goes around to the rear of the motor. Where that hose meets the Y-connector from the other side of the intake you'll find the PCV valve. It's almost impossible to see it with the hood installed, and even tougher to reach it.
