My 1993 Honda prelude has a loud knocking noise in motor what could it be


If it is really a knock by a mechanics use of the word, it is a SERIOUS wear of a rod bearing. Get some expert advice on this immediately. It it I am right, your engine could come apart and do considerable damage.

No if the oil light has flickered you have oil pressure loss some time just belive the sensor do help us out. lifter do not cause oil pressure loss pressure is built in the rotation of the crankshaft. The knock under the plenum will point you to that cylinder that is affected, (main bearing) as for a 1995 the injectors can only cause a misfire but no knocking noise,will they honor the warranty

If my car is low on oil and the engine is making a knocking noise and the check engine light came on can i change the oil with engine clear and will that fix the problem?


If things have degraded to the point the engine is knocking, it's unlikely anything you'll do now will remedy the problem. At the least this could call out new rod and/or main bearings. perhaps even a crankshaft.

Keeping a close eye on oil levels can help prevent things like this happening.

Sorry!

It sounds like you have slipped a bearing and you'll need a new engine. You get most of your oil pressure from your connecting rod bearing and crank shaft bearing, you still have some oil pressure. No oil pressure will cause your engines ECM to shut the engine down, but from what you have described. The engine is to far gone for repairs and a engine swap would be the more economical thing to do.
Thank you for using fixya and sorry for the bad news.

Oil pressure light on and knocking noise now


The light comes on when the oil pressure is too low, when the sending unit is bad, and, if you have too much oil in the engine and it whips the oil so much that the oil pump cannot pull the oil in since it is mainly bubbles

The knocking sound comes from a shortage of oil to he bearings, tapping comes from the valve train under the rocker cover (cylinder head).

Make sure you haven't lost any oil & that it isn't overfull and correct that if needed. Beyond what I've mentioned, you would be looking at the oil pump needing to be replaced or major engine repair if the bearings have spun or worn excessively.

good luck

KNOCKING ENGINE


Hi. There are two main issues that will cause the engine to knock. The first will be the oil pump. If the oil pump is failing, or damaged, this will produce a low oil pressure state. Low oil pressure will cause the internals to not receive the necessary lubrication needed for optimal performance. This low pressure state will cause the rod bearings to ware, thus, producing this knocking noise. This will be accompanied by a low pressure, or illuminated oil light. The next issue will be worn, or damaged rod bearings. These vital bearings can fail if the bearing clearance is excessive, or worn. They will, also, fail if the oil supply is not sufficient. This inspection will require you to drain all oil and coolant, and the dropping of the oil pan, to expose these bearings.Worn, or excessive bearing clearances will cause a knock.

NOTE_ There is another issue that i should warn of. If There is sufficient sludge build up in this engine, due to not changing the oil regularly, or not administering scheduled engine flushing, this will cause the internal oil ports to clog up, thus, inducing poor oil circulation. This will damage the entire engine. If you have not had this engine flushed, i would recommend to schedule this , asap.

Engine knock hard over 2500 rpm


Does the oil light come on or the knock occur during the engine warm up after a cold start?
There could be a couple of problems causing the issue. You could have an oil pressure pump or pump pressure regulator sticking. I would have a mechanical oil pressure gauge installed and verify oil pressure at idle and 2500 rpms to make sure oil pressure is in normal ranges.
You could also have excessive piston rod bearing, crankshaft bearing or cam shaft bearing wear that will cause oil pressure to drop too low to prevent the rod knock your hearing at 2500 rpm.
You said a knock and not a ticking noise,so I don't believe a lifter is the issue at 2500 rpm.
Start with the oil pressure check and go from there.
Let me know.
Regards,

Oil pressure drops when idling and knock from main bearing.


How many miles on it? Could be the oil pump if the oil level is full.

Knocking noise in engine 1998 jeep cherokee


Knocking noise can come from one of three places. Broken flywheel, Worn rod or main bearing. (bearing problems usually are accompanied by lowered oil pressure) An experienced technician can usually tell which is which. If bearing wear is on the rod bearings only and is light, it can usually be corrected. Main bearings require engine removal and is far more expensive. The oil pump should be replaced with either, but is not the cause of the problem. Extreme wear on bearings will also damage crankshaft. If so, it must be replaced.
