Customer Question
I have a 98 sunfire...
I have a 98 sunfire with the 2.4L, I have a oil leak in the valve cover. This is the twin cam (DOHC) and when I remove the valve cover bolts it acts like the cam is attached to the valve cover. This doesn't seem right to me. also the valve cover seems to go into the timing chain housing. how do I remove the valve cover properly?

2.3L and 2.4L DOHC Engines
INTAKE CAMSHAFT

See Figures 1, 2, 3, 4 and 5

  1. Disconnect the negative battery cable.
  2. Detach the ignition coil and module assembly electrical connections.
  3. Unfasten the ignition coil and module assembly-to-camshaft housing bolts, then remove the assembly by pulling it straight up.

  1. Remove the power steering pump.
  2. Detach the oil/air separator (crankcase ventilation system). Leave the hoses attached to the separator, disconnect from the oil fill, front cover and intake manifold, then remove as an assembly.
  3. Unfasten the vacuum line from the fuel pressure regulator and fuel injector harness connector.
  4. Disconnect the fuel line retaining clamp from the bracket on top of the intake cam housing.
  5. Unfasten the fuel rail-to-camshaft housing retaining bolts, then remove the fuel rail from the cylinder head. Be sure to cover the injector openinge in the cylinder head, cover the injector nozzles and leave the fuel lines attached and position the fuel rail aside (on top of the master cylinder).

Click image to see an enlarged viewFig. 2: After removing the fuel rail, cover the injector openings in the cylinder head to prevent any debris from falling in

  1. Disconnect the timing chain housing at the intake camshaft housing but do not remove from the vehicle.
  2. Unfasten the cam housing cover-to-housing retaining bolts and the cam housing-to-cylinder head bolts.
  3. Use the reverse of the tightening procedure (in the accompanying figure) when loosening the camshaft housing-to-cylinder head bolts.
  4. Push the cover off the housing by threading four of the housing-to-head retaining bolts into the tapped holes in the cover. Make sure to tighten the bolts evenly remove the cover from the vehicle.

  1. Fasten the timing chain housing.
  2. Uncover fuel injectors, then lubricate new injector O-ring seale with clean engine oil and install on the injectors.
  3. Uncover the injector openinge in the cylinder head, then install the fuel rail onto the cylinder head. Install the fuel rail-to-cylinder head retaining bolts and tighten to 19 ft. lbs. (26 Nm).
  4. Install the fuel line retaining clamp and retainer to the bracket on top of the cam housing.
  5. Connect the vacuum line to the fuel pressure regulator. Attach the fuel injector harness connector.
  6. Install the oil/air separator assembly. You may want to lubricate the hoses to ease installation.
  7. Lubricate the inner surface of the camshaft seal with clean engine oil, then install the seal into the camshaft housing using tool J 36015, or equivalent seal installer.
  8. Using tool J 36015 or equivalent pulley installer, install the power steering pump drive pulley onto the intake camshaft.
  9. Install the power steering pump assembly and the drive belt. Adjust tension to specification.
  10. Fasten any spark plug boot connector assembly that stuck to a spark plug back onto the ignition coil and module assembly.
  11. Position the coil and module assembly over the spark plugs, then push the assembly straight down. Make sure it is properly seated.
  12. Clean off any loose lubricant from the coil and module assembly-to-camshaft housing bolts. Apply pipe sealant GM part number(NNN) NNN-NNNNor equivalent, onto the bolts, then tighten the bolts to 16 ft. lbs. (22 Nm).
  13. Attach the coil and module electrical connector.
  14. Connect the negative battery cable, then start the engine and inspect for oil leaks.

EXHAUST CAMSHAFT

See Figures 3, 4 and 5

  1. Disconnect the negative battery cable.
  2. Detach the ignition coil and module electrical connection. Remove the coil and module assembly-to-camshaft housing bolts, then remove the assembly by lifting it straight up.

I always thought that they were typical valve covers. I have a manual on this car but unfortunately it seems like the 2.2L was the most common engine so it covers that engine more than the 2.4.
Auto Mechanic: Mike V., Auto Service Technician replied 9 years ago
Yes,it is much more involved then the 2.2L .I see that alot with the GM products.Some days just wonder what they were thinking?
