97 Nissan 200sx wont stay running when put in gear. When idling sometimes when engine is reved up it stalls, other times while idling I can rev it up and its smooth but once I put it in gear it...

You'll need to change the distributor, as the distributor shaft oil seal has gone bad. Without sufficient spark, you'll have no power. Don't forget a new cap/rotor.

Oil leak on driveway coming from front of engine

Dear Sir,
Here is the oil leaking Problem Identifying Technique

Engine oil leaks from the valve cover gasket are common.

  • The intake manifold plenum gasket may leak and cause increased oil consumption/burning and a spark knock during acceleration; the gasket should be replaced.
  • External oil leaks from valve cover gaskets, intake gaskets (front or rear), and the rear crankshaft (rear main) seal area are common. The rear main seal is an unlikely source. Normally, the bearing cap mating surfaces (as well as the sealing surface between the oil pan and bearing cap) are the source for the leaks.
  • Engine oil leaks at the distributor can be misdiagnosed as leaks from theintake manifold seal, oil pan gasket, or rear crankshaft (rear main) seal. A revised distributor is available if oil is found inside the distributor.
  • If the oil filter casing shows signs of distortion from excessive oil pressure, theoil pump should be replaced.
  • Often misdiagnosed as a leaking oil filter gasket, the oil filter adapter can seep from between the adapter and engine block.
  • Carbon buildup on the top of the piston is common. As the buildup increases with mileage and over time, symptoms may vary from light ticking, to ticking/hammering, to hammering/knocking noises. Fuel injector cleaner often solves the problem.

    Leaking oil left side of motor

    Since it's not clear whether you mean driver side or passenger side, I will address both.

    On the driver side, the most common leak is from the distributor. This can be caused by the distributor shaft exterior o-ring, or it can be caused by the distributor shaft interior bearing seal. To determine which it is, remove the distributor. First detach the spark plug wires, then undo the bolt that holds the distributor to the head, then pull the distributor out of the head. You will see the o-ring on the exterior of the distributor shaft. This is a $0.50 part, so just replace it with a new one as long as you have the distributor out. The bearing seal is on the inside of the distributor. To inspect it, undo the three bolts holding the cap to the distributor body. Pop the rotor off the shaft, the unclip the inside plastic cover. If you see any oil inside the distributor or the distributor cap, this means the seal is leaking and must be replaced. You can get a seal and bearing replacement kit from Or, you can just buy a new distributor. Note: To get the distributor back in place you must align the shaft correctly with the notch in the camshaft. There is a right way and a wrong way. If the shaft seems to be aligned but does not go in, pull it out and rotate it 180 degrees, then put it back in.

    The other possibility on the driver side of the engine is the main seal between the engine and transmission. If this is the case, you would have to either drop the transmission or pull the engine to replace it.

    What if the oil is leaking on the passenger side? If it's coming from behind the timing belt cover, there is a camshaft seal and a crankshaft seal, both of which can leak oil. To get to them, you will have to remove all accessory belts and the alternator, remove the exterior crankshaft pulley, remove the engine mount (support the engine) and the timing belt covers, remove the timing belt, then the crankshaft pulley and/or camshaft pulley, whichever is necessary to replace the leaking seal(s).

    Where else could oil be leaking from? If it's coming out from near the top of the engine, that's the valve cover gasket. Remove the valve cover and replace the gasket. While you're at it, replace the spark plug tube seals.

    If it's coming out from near the bottom of the engine, it could be the oil pan gasket. Remove the oil pan and replace the gasket.

    One more possibility for oil leakage: The head gasket. But in this case you would have noticed other symptoms besides just an oil leak.

    Good luck! Let us know how it turns out.

    Want to remove and replace the distributor, how is

    This sounds like the oil seal on the distributor needs replacing. I have not got the the timimg details but you can set it up this way until you can get the specs.

    1. Set the rotor arm to No 1 cylinder.
    2. Now mark this on the distributor.
    3. Mark the bottom of the distributor and the housing (inline with each other).
    4. Now put the car in gear and do not turn the engine.
    5. Check your timing marks on both your cam and crank shafts.
    6. Take out the distribuor and replace the the worn seal.
    7. Put back the distributor while lining up all the alinement marks that you have made.
    8. Now nip up the the distributor but do not full tighten it.
    9. Check your alinement marks, take the car out of gear and start the engine.
    10. If the engine is not running correctly, you can increase or decrease the engine speed by moving the distributor slightly to the left or right.
    11. When you have the engine tick over speed to your liking you can stop the engine and and tighten up the distributor.
    Following these instructions you should be only a few degrees out at the most.
    When you get the the correct timing information you can use a timing light to rset up the ignition timing.

    Does a 1991 Dakota 5 2L have a crankshaft position sensor?

    no it has a distributor here is the prodeure for the timing sensor under the cap.
    1. Disconnect negative battery terminal, disconnect distributor lead wire at the wiring harness connector.
    2. Release distributor cap retainers and lift the distributor cap off.
    3. Scribe a mark on the edge of the distributor housing to indicate the position of the rotor. Use the mark as a reference when reinstalling the distributor.
    4. Remove the distributor hold down bolt and clamp, and carefully lift the distributor out of the engine.

    1. Clean the top of the cylinder block to insure a good seal between the distributor base and block. If the engine has not been cranked with distributor removed, proceed with step 2. If the engine has been cranked with the distributor removed proceed to step 3.
    2. Position the distributor into the engine. Make sure the O-ring seal is in place on the distributor housing. Align the rotor with the mark previously scribed on the distributor housing. Engage the tongue of the distributor shaft with the slot in the distributor oil pump drive gear. Proceed to step 4.
    3. If engine has been cranked with distributor removed perform the following:
      1. Rotate the crankshaft until number one piston is at the top of its compression stroke. The mark on the crankshaft vibration damper should be in line with the "0" TDC mark on the timing chain case cover.
      2. Rotate the distributor rotor until it is positioned pointing at the number one distributor cap terminal.
      3. Lower the distributor into the engine, making sure the O-ring seal is in place. Engage tongue of distributor shaft with slot in the distributor oil pump drive gear.
    1. Install the distributor hold down clamp and screw and tighten finger tight. Install distributor cap and wires, making sure all high tension wires are firmly secured in cap towers.
    2. Connect pick-up leads and negative battery cable lead. Set ignition timing, refer to ADJUSTMENT PROCEDURES for timing adjustment
