If a 1996 Chevy Lumina has lots of knocking in the engine should you replace the oil pump?

If you have lower end knocking (rods or mains) an oil pump won't do much good. Plan on an engine rebuild with rod reconditioning and have the crank turned. Also, check the cylinders for taper and while it's down have the heads reconditioned, replacing any valves that look too far gone. Replace cam and lifters if there is any pitting or flattening on either.

A water pump should have nothing to do with the bearing in your engine. If you are hearing a knocking from the engine then you are going to need to replace/rebuild. I have seen bad waterpumps make knocking nosies but you said it was new. Id check your work!

When an engine is cold, the oil is thicker, and flows slower. When oil doesn't get to valvetrain components quickly, you'll hear knocking, also known as valvetrain clatter. As the engine warms up the knocking should go away.

It may be map sensor but engine knocking cause of another reason. You should check your spark plug , I.S.C valve , Injector and engine Compressor. thanks It may be map sensor but engine knocking cause of another reason.

The 1994 Chevy Lumina Van fuse box will be located next to the battery box. The fuse box cover should be labeled as such.

Engine oil does not cause a engine knock. It is caused by pre-ignition, which can have many causes, including the wrong grade of fuel octane. Make sure that you are choosing the correct fuel for your vehicle. You may want to take the vehicle to a mechanic, as engine knocking can seriously damage your engine.

Replace the head gasket for sure. That is assuming you did not continue to drive the vehicle until you destroyed the engine internally.

You should never have to replace it. The timing chain is designed to last the life of the engine. It is normally replaced when the engine is overhaul.

I belive that there is no adjustment on the serp belt on your lumina. Should be a spring loaded tensioner. If you are having problems with the belt slipping you most likely need to replace the belt/ tenssioner.

When an engine runs as it should the fuel/air mix in the combustion chamber ignites at the spark plug and the flame front spreads from there. In an engine that's knocking there are hotspots in the combustion chamber causing the fuel/air mixture to ignite prematurely a bit all over the place.

Well, I have a 1990 Lumina Euro, 4 door and it has a 3.1 in it. Yours should have the engine size on the block. Mine does. Just pop the hood and look on top. :o)

Take out the whole dash and then the heater core should be behind the glove box on the passenger side.

Timing chains are designed to last the life of the engine. So, replace the timing chain when the engine needs rebuilding.

there are a few reasons for engines knocking......... - bad type of fuel - higher gear ratio at slower speeds if your engine knocks when you start it up then you have probably got a bad or dirty fuel in your car... change the filters or just get away with using it and change your petrol station if the engine knocking happens during driving then its because you are putting more gas on at lower speeds and higher gear ratios...you just need to lower your gear. say change from gear 3 to gear 2 and try increasing the gas gradually and slowly and the knocking should go away....

Run a "compression test" to see if the engine overheated and warped the head.
