Question about Saturn SL

2 Answers

I have a 1996 saturn with a 1.9 engine and i'm trying to replace the head gasket. I have to remove the timing chain in order to pull the head. I got all of the timing cover bolts out inluding the harmonic balancer and center bolt and cannot remove the cover. Would there be anything else holding it on?

I NEED TIMING CHAIN DIAGRAM FOR VQ20 NISSAN SERFIRO 1999


Instructions
  1. Remove Your Timing Chain
    • 1 Check your owner's manual for the recommended mileage for replacing your timing chain. Replacement for a Nissan Altima is 60,000 miles.
    • 2 Locate the timing chain. Replace it if the automatic chain adjuster (also known as the tensioner) is damaged or worn.
    • 3 Drain the cooling system and disengage the negative battery cable. Undo the spark plug wires and set the No. 1 piston at "Top Dead Center" (TDC) of the compression stroke.
    • 4 Disconnect the engine undercover, vacuum and fuel hoses, harness and connectors, drive belts, power steering reservoir, alternator and bracket, upper radiator hose, air duct, front exhaust tube, intake manifold collector supports, collector and exhaust manifold and the distributor.
    • 5 Prop up the oil pan and take out the front engine mounting, the valve cover, camshaft sprockets, cam bearing caps, camshafts, cylinder head bolts (reverse the installation order), cam sprocket cover, upper chain tensioner, chain guides and chain, idler sprocket bolt, cylinder head, intake manifold and cylinder head gasket and the steel oil pan.
    • 6 Place a steel cutter between the steel and aluminum oil pans. Slip the cutter around the oil pan's edge. Disengage the steel oil pan, baffle plate, oil strainer and the front tube.
    • 7 Secure the car on jack stands and place a seal cutter in between the oil pan and cylinder block. Slip the cutter around the oil pan's edge.
    Install Your Timing Chain
    • 8 Reconnect the crankshaft sprocket, oil pump drive spacer, idler sprocket and lower timing chain. Position the lower timing chain on the sprockets and line up the mating marks.
    • 9 Rub on an unbroken bead of liquid gasket and put in a new front cover and oil seal. Secure the bolt at 105 to 112 foot pounds (142 to 152 Nm).
    • 10 Eliminate any old material from the pan and cylinder block mounting surfaces. Rub on a 3.5 to 4.5mm bead of liquid gasket over the oil pan and cylinder block.
    • 11 Attach the upper timing chain to the idler sprockets and secure the cylinder head bolts.
    • 12 Refill the cooling system and add clean oil in the engine.
    • 13 Hook up the negative battery cable and any other disconnected parts or items. Start the engine and look for leaks.
Tips & Warnings
  • Procedures for replacing timing chains in Nissan Altimas vary slightly depending on engine size.
  • Make sure the new timing chain matches the chain you are removing.

I'm not sure which gasket I need to replace. I am thinking it is the Head Gasket, but I've also read some threads online that say it might be an intake gasket. 3100 ENGINE. The previous owner already...


Well, to say the least you have a problem. It may or may not be a head gasket. It might be a cracked cylinder wall. The oil being contaminated is certainly an issue that needs to be addressed. In most cases you can locate the engine serial number and figure out which one it is. Most manufacturers, when they release 2 different engines of the same size for a model, do so with one as a turbo and the other a non turbo which is one method to tell which one is used. The simplest way, since you have to remove the heads anyway, is pull the heads and when you go to the parts store to get the gaskets take the old ones with you and match them on site. As far as the contamination goes I already mentioned it could be the cylinder wall being cracked, it could also be be that the timing chain wore a hole in a water jacket in the engine front cover which is usually made of aluminum. This happens when a timing chain guide snaps or comes free in the motor or a bolt holding the timing chain in place comes out, I had this happen in a Toyota motor. To get the new head gaskets take the old ones with you and match them at the store, the rest you will need to address as you come across them.

Whats the proper order and torque specs for a 99 32v northstar head?


REMOVAL & INSTALLATION NOTE: The manufacturer recommends that the entire powertrain be removed from the vehicle before removing the cylinder heads.
  1. Before servicing the vehicle, refer to the precautions in the beginning of this section.
  2. Drain the cooling system.
  3. Properly relieve the fuel system pressure.
  4. Remove or disconnect the following:
    • Negative battery cable
    • Powertrain assembly
    • Intake manifold
    • Cam covers
    • Harmonic balancer
    • Timing chain front cover
    • Oil pump
    WARNING
    Align all timing marks before performing the next step.
    • Chain tensioner from the timing chain
    • Cam sprockets
    NOTE: The timing chain remains in the chain case.
    • Timing chain guides, access for the retaining screws is through the plugs at the front of the cylinder head
    • Water crossover
    • Exhaust manifold
    • Cylinder head bolts by reversing the torque sequence
    • Cylinder head and discard the gasket
    WARNING
    With the camshafts remaining in the cylinder head some valves will be open at all times. Do not rest the cylinder head on a flat service with the cylinder face down, or valve damage will result. NOTE: Clean all gasket mating surfaces. Clean the head bolt holes in the crankcase. WARNING
    Be careful when cleaning aluminum gasket surfaces to prevent damage to the sealing surfaces.
  5. Check the cylinder head for warpage; it must be less than 0.002 in. (0.05mm). If the cylinder head was resurfaced, the dimension between the combustion chamber gauge pad and the deck surface must be at least 10.5mm. To install: NOTE: Refer to Section 1 of this manual for the cylinder head torque sequence illustration. The illustration is located after the Torque Specification Chart.
  6. Install or connect the following:
    • New cylinder head gasket
    • Cylinder head, lubricate the bolts with engine oil
  7. Torque the M11 bolts, in sequence, as follows:
    1. Step 1: 22 ft. lbs. (30 Nm).
    2. Step 2: Turn an additional 60 degrees.
    3. Step 3: Turn an additional 60 degrees (total 180 degrees).
  8. Torque the M6 bolts to 106 inch lbs. (12 Nm).
  9. Set the camshaft timing
  10. Camshaft guide bolt access hole plugs in the cylinder heads. The plugs should be seated and snug
  11. Install or connect the following:
    • Intake cam covers
    • Oil pump
    • Timing chain front cover
    • Harmonic balancer
    • Cam sprockets
    • Chain tensioner to the timing chain
    • Timing chain guides
    • Intake manifold
    • Water crossover
    • Exhaust manifold. Torque the nuts to 22 ft. lbs. (30 Nm) or the bolts to 18 ft. lbs. (25 Nm).
    • Powertrain assembly
    • Negative battery cable Fig. 1: Minimum head resurface dimension 7922vg04.gif

  12. Fill the cooling system.
  13. Evacuate and charge the air conditioning system.
  14. Run the engine and check for leaks.

What would cause my1999 Saturn sl1 not to start after a new head gasket was put on? Ok so today we replaced the head gasket on my 1999 Saturn Sl1 single cam. We made sure the timing chain was put back on...


Check the cam/crank sensors. Also, if the car happens to have a distributor, make sure it is not 180 degrees off. If this does not help, then do a compression check. Remember, and engine only needs three things to run. Fuel, Spark, and Compression. (in order of course.) The firing order for your engine is 1,4,3,2.

HOW DO I REPLACE THE HEAD GASKET ON A 1993 PASEO?


you have to take the top part of the motor off to get to the head gasket. all the way down to the heads.

WHEN REPLACING THE HEAD GASKET.


Yes, the chain has to come off. The cam gear that is driven by the chain is mounted on the cam, inside the head, and the crank pulley down at the bottom is what drives it via the chain. The chain has to be removed in order to remove the head.

Usually the pulleys are mounted onto their shafts with a bolt through the center of each pulley. That will have to be loosened and removed (which is much easier if it's loosened before you remove the chain, so that the chain holds the pulley still and keeps it from moving). My question is, why do you need to remove the pulley? Once the chain is off, and everything else is disconnected, the head will lift off with the pulley intact, and the crank pulley doesn't need to come off as it has nothing to do with a head gasket service. Is there another issue that requires the pulley to come off, or are you replacing the head with one whose cam pulley is missing?
