Sounds more like your motor is pressurised causing oil to flow out the easiest orifice. Put a compression test on cylinders if OK check valve stem seals for hardness.
But I would say you have blow by on rings.

SOURCE: hesitation, stalling like out of gas

Clogged Catalytic Converter. What happens is as you push down harder on the accelerator you force more gas into the system causing a slightly richer mixture and more exhaust flow is neccessary. The easiest way to look for a clogged cat is when it's dark out take it for a ride causing it perform it's problem look under the vehicle if the cat is literally glowing red hot you either have a clogged cat or an extremely rich fuel mixture.

SOURCE: engine misses 4.9l

here is the next step, you buy a fuel pressure test gauge from a parts store and hook it up at the test port at rear of the engine on top, it looks like a tire valve but metal, will have a plastic cap on it ( or should), test the fuel pressure should be around 50 PSI at idle. How is the fuel filter, ever been changed? it is due every 30,000 miles

SOURCE: 1989 ford f150 loss of power

1989 is fuel injected, on the intake there is idle air control valve, make sure this is not dirty, also you may want to check the coolant temperature sensor, if the engine thinks it is warmer then waht it is the fuel air ratio will be off and your truck will run bad.

It sounds to me like you replaced everything but the most likely cause of a stall while driving...The crank sensor.

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.

    Oil leaking from toyota camry 1992, 1994 model


    You don't say what engine it has. The 4-cyl was a better than the V6 for oil leaks.

    The V6 had oil leaks from

    -rear bank cam cover gasket

    -distributor o-ring seal

    -oil filter bracket o-ring seal

    -crankshaft nose oil seal (less common)

    -rear main bearing oil seal (expensive, just leave it)

    The 4 cyl leaked oil from

    -distributor o-ring seal

    -camshaft cover gasket

    -rear main bearing seal (expensive, leave it)

    I have a 1994 cadillac seville sts that is leakin quit a bit of oil...we thought it was a rear main seal but after taking it apart found out that's not the case.... it has a northstar engine in it


    the northstar engines are notorious for rear intake manifold leaks, leaks down rear of engine and looks like rear main seal. Also check oil pressure switch for cracks

    I am looking to buy a 96 ford f250 powerstroke 7.3L. It needs a new oil pan gasket and or a rear main seal. I just want to make sure im not getting screwed on this deal. how much would it cost to repair...


    The pan gasket is cheap. Remove the pan install new gasket. A shop would charge around $100. Now the main seal, it will run you $800+ to fix. Difficult and time consuming.

    My toyota vienta 3VZ-FE 1996 - oil leak onto exhaust


    Hi,

    That engine will leak oil from

    - camshaft end seals
    - distributor shaft o-ring (appears on top of transaxle housing)
    - oil filter bracket to block o-ring seal (drips on front bank exhaust)
    - crankshaft nose oil seal (have done with timing belt change)
    - rear main seal (expensive, leave it be)

    Think I need oil pan gasket


    It's probably the front crank seal or the cam seal. Kinda big job for a novice. The car only has one oil pan. The back one she refered to is for the transmission,if it's automatic. Never saw a oil pan gasket leak on a nissan '96 & up.

    Make sure when you changed the oil filter that the old gasket didn't stick to the block when you installed the new filter.
