I have a knocking sound around the belt drive case or the top of the engine and it smokes people have told me valves and clutch and piston idk what to do


dear user,
In some cases, gasoline problems cause the irregular combustion that leads to knocking sounds in an engine. This can occur because of problems with gasoline octane. Gasoline's octane ratings signifies the amount of compression the fuel can handle before spontaneous ignition. When this spontaneous ignition happens instead of the normal ignition, knocking may occur and can cause damage to the engine. The lowest octane gases are typically the least capable of withstanding compression and are more likely to ignite this way.
Sometimes the sound of engine knocking is caused by something other than the typical combustion process problems. For example, some types of mechanical issues may cause these knocking sounds. Such mechanical issues can include defects in the crankshaft bearings, broken flywheels, and water pump bearings that are worn out.

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 leak in front of engine around the distributor. top of engine


    Its either the valve cover gasket or the o ring that seals the distributor.
    It could be coming from either, so look for oil on the valve cover above
    the distributor. If you see oil there its the valve cover.
    If you dont see oil coming from the valve cover above the distributor, then look or touch
    the bottom of the distributor and if there is oil there then the distributor oring is
    whats leaking.

    1988 jeep wrangler with oil leak on top of engine and can smell it inside while driving.is it a easy fix?


    MOST OIL LEAKS COME FROM A BAD GASKET! IF YOU CAN LOCATE THE SOURCE OF THE LEAK, YOU CAN FIX IT! IT COULD BE JUST A VALVE COVER GASKET LEAK! YOU CAN UNBOLT THE VALVE COVER, REMOVE IT, TAKE THE OLD GASKET OUT, CLEAN UP THE INSIDE, TO INSURE THERE IS NO OLD GASKET STUCK ON THE COVER! PUT THE NEW GASKET ON, AND REMOUNT THE VALVE COVER! RULE OF THUMB: WHEN TIGHTENING IT DOWN, START WITH THE MIDDLE BOLTS, SNUG THEM UP, THEN WORK YOUR WAY TO THE OUTSIDE! ONCE YOU HAVE SNUBBED THEM UP, GO BACK TO THE MIDDLE, AND TURN THE BOLT 1/8 TO 1/4 TURN EACH IN THE SAME WAY ( FROM THE MIDDLE- OUT!

    My engine knocks loud and Í dont know what to


    If the knocking is a 'tinging' sound...valves are shot. The Paseo has an issue with the head getting warped and leaking oil through the gasket, if the oil has been low too often for lengths of time the head heats and warps.
    Open the oil cap and feel around inside with your finger (ensure engine is off and cooled first) rub your fingers together to feel for grit which would most likely be valve shavings. This should be easy to find since it's recently had an oil change.
    Worse case scenario would be a rod broken but that would be a LOUD knocking/bonking sound and definitely expensive.

    My 1995 eldorado burns oil


    Take out the pvc while its running. Look for smoke to come out of pvc hole. If it does than you probably need rings. This would explain the oil loss. Look around the motor for oil "wet spots". You may just have a valve cover leak.Shake the pvc while its out. If it rattles its good. If not, replace. Hope it helps.
