The engine has blown. I need to replace it or change pistons and rings. How difficult is it to change pistons and rings?


It can be time consuming and the end result may not be desirable if you haven't done it before.
--- The following is just a sample of what to do once the engine is torn down: Pistons and Connecting Rods
  1. Before installing the piston/connecting rod assembly, oil the pistons, piston rings and the cylinder walls with light engine oil. Install connecting rod bolt protectors or rubber hose onto the connecting rod bolts/studs. Also perform the following:
    1. Select the proper ring set for the size cylinder bore.
    2. Position the ring in the bore in which it is going to be used.
    3. Push the ring down into the bore area where normal ring wear is not encountered.
    4. Use the head of the piston to position the ring in the bore so that the ring is square with the cylinder wall. Use caution to avoid damage to the ring or cylinder bore.
    5. Measure the gap between the ends of the ring with a feeler gauge. Ring gap in a worn cylinder is normally greater than specification. If the ring gap is greater than the specified limits, try an oversize ring set. Fig. 5: Checking the piston ring-to-ring groove side clearance using the ring and a feeler gauge tccs3923.gif

    6. Check the ring side clearance of the compression rings with a feeler gauge inserted between the ring and its lower land according to specification. The gauge should slide freely around the entire ring circumference without binding. Any wear that occurs will form a step at the inner portion of the lower land. If the lower lands have high steps, the piston should be replaced. Fig. 6: The notch on the side of the bearing cap matches the tang on the bearing insert tccs3917.gif

  2. Unless new pistons are installed, be sure to install the pistons in the cylinders from which they were removed. The numbers on the connecting rod and bearing cap must be on the same side when installed in the cylinder bore. If a connecting rod is ever transposed from one engine or cylinder to another, new bearings should be fitted and the connecting rod should be numbered to correspond with the new cylinder number. The notch on the piston head goes toward the front of the engine.
  3. Install all of the rod bearing inserts into the rods and caps. Fig. 7: Most rings are marked to show which side of the ring should face up when installed to the piston tccs3222.gif

  4. Install the rings to the pistons. Install the oil control ring first, then the second compression ring and finally the top compression ring. Use a piston ring expander tool to aid in installation and to help reduce the chance of breakage. Fig. 8: Install the piston and rod assembly into the block using a ring compressor and the handle of a hammer tccs3914.gif

  5. Make sure the ring gaps are properly spaced around the circumference of the piston. Fit a piston ring compressor around the piston and slide the piston and connecting rod assembly down into the cylinder bore, pushing it in with the wooden hammer handle. Push the piston down until it is only slightly below the top of the cylinder bore. Guide the connecting rod onto the crankshaft bearing journal carefully, to avoid damaging the crankshaft.
  6. Check the bearing clearance of all the rod bearings, fitting them to the crankshaft bearing journals. Follow the procedure in the crankshaft installation above.
  7. After the bearings have been fitted, apply a light coating of assembly oil to the journals and bearings.
  8. Turn the crankshaft until the appropriate bearing journal is at the bottom of its stroke, then push the piston assembly all the way down until the connecting rod bearing seats on the crankshaft journal. Be careful not to allow the bearing cap screws to strike the crankshaft bearing journals and damage them.
  9. After the piston and connecting rod assemblies have been installed, check the connecting rod side clearance on each crankshaft journal.
  10. Prime and install the oil pump and the oil pump intake tube.
  11. Install the auxiliary/balance shaft(s)/assembly(ies).
OHV Engines CAMSHAFT, LIFTERS AND TIMING ASSEMBLY
  1. Install the camshaft.
  2. Install the lifters/followers into their bores.
  3. Install the timing gears/chain assembly.
CYLINDER HEAD(S)
  1. Install the cylinder head(s) using new gaskets.
  2. Assemble the rest of the valve train (pushrods and rocker arms and/or shafts).
OHC Engines CYLINDER HEAD(S)
  1. Install the cylinder head(s) using new gaskets.
  2. Install the timing sprockets/gears and the belt/chain assemblies.
Engine Covers and Components Install the timing cover(s) and oil pan. Refer to your notes and drawings made prior to disassembly and install all of the components that were removed. Install the engine into the vehicle. Engine Start-up and Break-in STARTING THE ENGINE Now that the engine is installed and every wire and hose is properly connected, go back and double check that all coolant and vacuum hoses are connected. Check that your oil drain plug is installed and properly tightened. If not already done, install a new oil filter onto the engine. Fill the crankcase with the proper amount and grade of engine oil. Fill the cooling system with a 50/50 mixture of coolant/water.
  1. Connect the vehicle battery.
  2. Start the engine. Keep your eye on your oil pressure indicator; if it does not indicate oil pressure within 10 seconds of starting, turn the vehicle OFF. WARNING
    Damage to the engine can result if it is allowed to run with no oil pressure. Check the engine oil level to make sure that it is full. Check for any leaks and if found, repair the leaks before continuing. If there is still no indication of oil pressure, you may need to prime the system.
  3. Confirm that there are no fluid leaks (oil or other).
  4. Allow the engine to reach normal operating temperature (the upper radiator hose will be hot to the touch).
  5. At this point any necessary checks or adjustments can be performed, such as ignition timing.
  6. Install any remaining components or body panels which were removed. prev.gif next.gif

  2. Disconnect the fuel lines.
  3. Using the J 45722 or equivalent, remove the sending unit lock ring.






    chevy_aval15_02-04_j44402.gif



  4. Remove the sending unit and seal.
  5. Discard the seal.
    CAUTION
    Drain the fuel from the fuel sender assembly
    into an approved container in order to reduce the risk of fire and personal
    injury. Never store the fuel in an open container.

  6. Clean sealing surfaces.

To Install:

CAUTION
In order to reduce the risk of fire and
personal injury that may result from a fuel leak, always replace the fuel sender
gasket when reinstalling the fuel sender assembly.


  1. Install a NEW seal.
    CAUTION
    The fuel pump strainer must be in a
    horizontal position when the sending unit is installed in the tank. When
    installing the sending unit, assure that the fuel pump strainer does not block
    full travel of the float arm.

  2. Install the sending unit into the fuel tank.

change cam position sensor chy


  1. Disconnect the negative battery cable.
  2. Detach the electrical harness connector from the camshaft position sensor.
  3. Unfasten the camshaft position sensor mounting bolt. There is a hole in the bracket for tool access to the sensor mounting bolt.
  4. Rotate the sensor away from the engine block.
  5. Pull the camshaft position sensor up out of the chain case cover. Do not pull on the sensor wire.
There is an O-ring on the sensor case. The O-ring may make removal of the sensor difficult. A light tap on top of the sensor prior to removal may reduce the force needed for removal. Inspect the O-ring for damage and replace if necessary.
To install:
If the sensor removed is going to be re-installed, clean off the old spacer on the sensor face. A new spacer must be attached to the sensor face before installation. If the sensor is being replaced, be sure that a paper spacer is attached to the sensor face and an O-ring is positioned in the groove of the new sensor.
  1. Apply 1-2 drops of clean engine oil to the O-ring prior to installing the sensor.
  2. Install the sensor into the chain case cover and rotate into position.
  3. Push down on the sensor until contact is made with the camshaft gear. While holding the sensor in this position, install and tighten the mounting bolt to 10 ft. lbs. (14 Nm).
  4. Attach the electrical harness connector to the camshaft position sensor.
  5. Connect the negative battery cable.
