My oil pump went out on my car and now my engine is knocking. Would it be OK to start it and drive it up on a trailer?
Experienced mechanics share their insights in answering this question :
Even starting the engine with no oil pump or no oil pressure can damage the internal bearings, crankshaft, and camshafts. When you put it under a load like trying to get it on a trailer, you may damage the engine more than you have already.

A damaged oil pump (possibly caused by interference with the AC compressor bracket) can also cause a knocking noise from the engine compartment; a modified bracket is available from Dodge.
A bad oil pump will lose the ability to properly pump oil through your system. This will result in low oil pressure that could lead to further vehicle damage.
You shouldn`t drive with a failing oil pump for too long or you will risk damaging the crankshaft and the camshaft bearings. Additionally, driving with a bad oil pump implies a lack of lubrication which could damage the car`s hydraulic lifters.
As we mentioned, the high-pressure system uses the same oil the rest of the engine runs off, and that means it`s likely that your oil will break down more quickly than normal, or get thinned out. This can cause poor fuel system performance. You might notice your engine running poorly or bad fuel mileage.
When the oil pressure is low or oil level is low, internal engine components that depend on proper lubrication will start to wear metal-to-metal. This can and often does cause the knocking or grinding sound. This is a situation that should be inspected and repaired by a professional mechanic as soon as possible.
Commonly, engine knocking occurs because of a buildup of oily carbon deposits inside the combustion chamber. This can be caused by burning oil or incomplete combustion from misfires, which coats pistons, cylinder heads, and other parts of your engine with residue.
Without sufficient oil pressure, your car`s engine will operate with decreased lubrication and increased friction resulting in more heat. Engine overheating can be a complex issue. While it doesn`t always mean low engine oil pressure, low engine oil pressure can lead to an overheating engine.
Driving with this light on your dash can cause severe, irreversible engine damage. Although you can`t determine the severity of the oil pressure problem right away, the best thing you can do is to treat it like a worst-case scenario.
Low oil levels cause valves to burn up, seals to dry out, and internal parts to heat up and eventually deform or break. Until something breaks, the engine will continue to lose power and burn more fuel while running poorly.
Low engine oil is an indicator that there is a problem with the engine. If the level gets low, it can prevent proper lubrication of critical components inside the engine and cause starting problems, engine failure, and damage to critical components.
Knocking can damage the surface of the piston, the cylinder walls or the crankshaft bearings, all of which are expensive to repair. Modern computer-controlled injection systems can correct your fuel mixture to prevent knocking, but at the cost of engine performance.
It`s easy to misdiagnose the cause of engine knock, so you might have to pay a visit to your mechanic. Each of the engine knock causes on the previous page has a specific cure, and most of these fixes are simple. However, it doesn`t guarantee the knock will go away.
Adding more oil will make the noise go away, but it won`t solve the underlying cause of the noisy engine – the oil leak.

I have an engine knock and my oil pressure guage is reading high, then stops shortly after starting to drive.
ANSWER : Hello,
You may want to inspect your oil pump to see if it may not be causing the problem. If it is not pumping or circulating oil properly, it may also cause this type of increase in oil pressure that may be sporadic as you describe. When you first start the engine, the oil pump needs to work a bit harder than normal at first the get the oil circulated through the motor to all of the places it needs to go as the oil is much thicker when it is cold. As the engine warms up, the oil becomes thinner and flows a bit easier, which may be what causes the pressure to come back down once it is warmed up.

My car stutter starts, but only after driving it for a few minutes.
ANSWER : Hey there. This may also be caused by what is called the fuel pressure regulator. This is a unit that helps to maintain the fuel pressure at the proper level. When this is not working properly, the fuel pump may be pumping properly, but the fuel may not arrive at the fuel injectors at the proper psi. When this happens, this can cause a lean fuel condition which may cause the car to hesitate, misfire, or stall. If you would like to have an expert pinpoint the issue, a certified professional from YourMechanic can come to your car’s location to inspect the hard start problem and confirm which repairs are needed.

think i put wrong oil in car went few miles lose power car dies oil in spark plugs still starts low oil blinking light before die.
ANSWER : Hello. If you put too thick of an oil in the car, then you may have damaged the engine bearings but this should not have caused oil to get in to the spark plugs unless the oil got into the intake of the engine or one of the pistons rings broke. If you ran it without oil and then tried to put oil in thinking it would be okay after that, then you were not that lucky and broke or damaged all of the rings on the pistons. If you would like to have this looked over, a certified professional from YourMechanic can come to your car’s location to inspect the stalling issue and go over all of the relevant systems for a better diagnosis.

Check engine on knocking engine milky cap but not in oil change loud knocking noise while driving and cold start up
ANSWER : Coolant leaks can be external or internal. If the coolant is leaking internally into the cylinders or crankcase, that will require a fairly significant repair. If the coolant is leaking externally, unless the leak is at the head gasket or the lower intake manifold, external leaks can be repaired readily. On the engine you have it was really common to have coolant leaks at the lower intake manifold, so common that the gasket there was completely designed and a different repair procedure was specified (higher torque on the manifold studs). To get the coolant leak diagnosed, please use YourMechanic’s coolant leak diagnostic service link. The knocking noise is obviously of concern. Unfortunately, typically, such noise is from worn bearings, connecting rods, and other major components. The noise might be accompanied by low oil pressure. My best advice is have the cooling leak diagnosed in case that is readily resolvable. The mechanic can evaluate the noise and if it is internal the engine will eventually have to be disassembled and rebuilt.

Can front wheel drive car engine power rear wheel drive
ANSWER : Anything is possible with enough engineering. The changes you are looking at would take major structural changes and would definitely not be an easy job. You could possibly consult a manufacturing engineer to get more details on how this could actually be carried out and whether it would be feasible.

My car will not start Intermittently. I purchased a new battery 2 weeks ago and yesterday the car wouldn’t start. Got a jump and
ANSWER : The issue you are having is probably due to an intermittent fault in the starter motor itself or a deficiency in the starter electrical circuit, for example a large voltage drop due to a poor ground or a high resistance connection. These issues can be readily diagnosed and resolved on a mobile basis if you request a hard starting diagnostic. If you request that diagnostic, the responding certified mechanic will get this resolved for you promptly. Based on Toyota’s Factory Service Manual, the battery should not be disconnected if the vehicle engine is running. The battery acts as a large resistive voltage sink and consequently taking the battery out of the circuit, while the alternator is still running, can create a voltage spike on the car’s electrical system which is not good for voltage sensitive components such as the engine computer.
