Question about 1994 Toyota Camry

1 Answer

96 Toyota Camary. Engine ran fine but had a oil leak at front of engine. Removed front cover and replace oring for oil pump and crank shaft seal. Assembled making sure timing belt was installed correctly. Started engine,ran ok until idle slowed down. Idles at 300rpm and acts like its going to stall. Under load engine misses and will not run above 3,000 rpms. Engine backfires under load. Checked timing many times and tried in different spots. Removed and cleaned carbon from EGR valve.Open exhaust to run still misses. I have checked everything, the exhaust manifold does get cherry red after running. Any thoughts. this car has the 2.2 four cylinder

I have a massive oil leak

Main source of oil leak is going to be valve cover, crank seal, balance shaft seal and distributor o-ring.

Oil leak on a '92 Geo Tracker. Installed an O Ring, but still leaking. Any suggestions?

O-ring where? The drain plug? Distributor shaft? Or do you mean oil seal?
Geo oil drain plug specifies a compressible copper ring washer I think? Need to clean the surfaces well, and torque to spec. My own plug's seal is not perfect, but only a drop here and there usually. Autozone or NAPA can supply you a new plug and washer if needed.

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.

    1993 Toyota Celica GT oil leak from front of engine block

    The most common cause of all oil leaks is the valve cover gasket. The oil drips down from there and covers everything. If your valve cover is leaking, replace it first.

    Then the second most common leak in the front of the engine is the crankshaft seal. This seal should have been replaced when the timing belt is replaced as you have everything removed to get to it, and the seal is easy to replace. However if it is not replaced at that time then you will have to remove everything again to access it. The seal is 3 or four dollars, but the labor is two to three hours and you should replace the timing belt, idler pulleys, tensioner and water pump when you are in there, as that will all be removed. Hope this help. Good luck :O)

    Where is the oil pump located in A 1993 ford thunderbird V6?

    Inside the oil pan for the 2.3 and 5.0


    1. Disconnect the negative battery cable.
    2. Remove the oil pan.
    3. Remove the oil pump inlet tube and screen assembly.
    4. Unfasten the oil pump attaching bolts, then remove the oil pump gasket and the intermediate shaft.
    To install:
    1. Prime the oil pump by filling the inlet and outlet ports with engine oil and rotating the shaft of pump to distribute it.
    2. Position the intermediate driveshaft into the distributor socket.
    3. Place a new gasket on the pump body and insert the intermediate driveshaft into the pump body.
    4. Install the pump and intermediate shaft as an assembly.

    WARNING Do not force the pump if it does not seat readily. The driveshaft may be misaligned with the distributor shaft. To align, rotate the intermediate driveshaft into a new position.
    1. Install and tighten the oil pump attaching screws to:

      2.3L Engine: 12-15 ft. lbs. (16-20 Nm) 5.0L Engine: 22-32 ft. lbs. (30-43 Nm)
    2. Install the oil pan.
    3. Connect the negative battery cable, then start the engine and check for leaks.

    On the 3.8...

    The oil pump is mounted in the front cover assembly. Oil pan removal is necessary for pick-up tube/screen replacement or service.


    1. Disconnect the negative battery cable.
    2. Raise and safely support the vehicle on jackstands.
    3. Drain the engine oil, then remove the oil filter.
    4. If necessary, remove the oil cooler.
    5. Unfasten the oil pump-to-front cover retaining bolts, then remove the pump from the front cover.
    6. Lift the two pump gears from their mounting pocket in the front cover.
    7. Clean all gasket mounting surfaces.
    8. Inspect the mounting pocket for wear. If excessive wear is present, complete timing cover assembly replacement is necessary.
    9. Inspect the cover/filter mounting gasket-to-timing cover surface for flatness. Place a straightedge across the flat and check the clearance with a feeler gauge. If the measured clearance exceeds 0.004 in. (0.10mm), replace the cover/filter mount. Replace the pump gears if wear is excessive.
    To install:
    1. Lightly pack the gear pocket with petroleum jelly or coat all gear surfaces with Oil Conditioner D9AZ-19579-CA or equivalent, then install the the pump gears in the cover pocket. Make sure the petroleum jelly fills all voids between the gears and pockets.

    WARNING Failure to properly coat the oil pump gears may result in failure of the pump to prime when the engine is started.
    1. Position the pump body O-ring seal and install the pump body to the front cover using alignment dowels on the front cover.
    2. Tighten the pump retaining bolts as follows
      1. For vehicles through 1993, tighten the M8 bolts to 18-22 ft. lbs. (25-30 Nm) and the M10 bolts to 30-40 ft. lbs. (40-55 Nm).
      2. For 1994-96 vehicles, tighten the four smaller bolts to 15-22 ft. lbs. (20-30 Nm) and the two larger retaining bolts to 6-11 ft. lbs. (8-15 Nm).

    3. If removed, install the engine oil cooler. Install the oil filter.
    4. Carefully lower the vehicle, then refill the engine crankcase with the correct type and amount of engine oil.
    5. Connect the negative battery cable, then start the engine and check for leaks.

    1995 toyota camry leaking oil from behind the timing belt cover. Isn't this a major repair? Is the leak more than likely a camshaft seal?

    If you haven't had the timing belt replace (60,000 miles is the suggested service intervale) this is an overlap of having the timing belt replaced.
    If the timing belt is not due for replacement and its the cam shaft seal that is leaking. Its a pretty easy fix. Remove the top timing belt cover , and the crankshaft sensor wiring you may have to remove the front engine mount . Set #1 piston at TDC, Loosen tensioner w/ spring slip off belt. **Remove sprocket pull out old seal with a sharp pick. Greese and install new seal make sure its flush with its bore . Reistall sprocket. Slide belt over Cam sprocket tighten tensioner. Install cover and mount (if applicable) Check timing marks by turning crank two revolutions.
    ** If CamSprocket Bolt is difficult to remove then remove valve cover and use a 21mm wrench to hold the Camshaft while you crack off Cam Sprocket Bolt.
    You will see the groves on the Camshaft where you can place a wrench to hold the shaft.
    After you replaced the seal replace the valve cover gasket ONLY IF YOU HAD TO REMOVE THE COVER TO HOLD THE CAM WHILE REMOVING ITS BOLT.

    This is about as major as it gets.

    By the "Front" I am assuming that you mean the crankshaft end of the engine.
    If your engine is equipped with a balance shaft, there is a good possibility that the balance shaft seal has popped out. There is a "balance shaft seal retainer kit" available at your local dealer to fix this and prevent it from happening again. If this is not the case, it could be the front crank and/or oil pump seals. I have even seen cracked oil pump housings on these units.
