Engine is running fine. Oil level is good. Oil light comes on and off at random. Engine isn't knocking and runs great. Recently changed to GTX extended milage oil. Problem developed


The oil light comes on when the oil pressure sensor detects low oil pressure. The amount of oil has little to with it, although very low oil levels can cause loss of oil pressure. Since you aren't getting knocking, chances are the oil pressure sensor is defective. Replace it and monitor the situation closely. This could be a serious condition if allowed to escalated and it turns out to be an oil pressure issue.

Engine started knocking on a honda cr-v 2.0 vtec


check your oil level, color, and smell. My guess is that the low oil pressure light is on because of literal lack of oil to pressurize. Generally when you get that light and a knock it points to major engine repair or replacing the engine. Knocks due to oil pressure can indicate many things from a bad head gasket to a stretched rod or blown piston rings. Check your coolant reservoir for signs of oil entering the cooling system as it will float on top of the coolant. By the sound of it it needs major mechanical repairs

Engine knocking


engine knocking sound like worn engine bearings or low oil level. if oil level okay more likely oil pump has failed or engine bearings worn out or engine oil diluted with antifreeze or gasoline causing viscosity oil to be too thin.if oil and filter been changed.if you see check engine light flashing code scan for faulty knock sensor. if you see low oil light flashing engine knocking damaged to engine done.

did the oil light come on? it it did that means a low pressure situation which can cause con rod bearing damage. the knock sensor can cause that too.

I have a 95 oldsmobile 98 regency elite I cant find where the knock sensor goes I have a haynes manual but where it shows it wont go


Well, for starters, your problem got posted under 1985 Oldsmobile 98 - then you said it was a 95 Oldsmobile 98 Regency Elite (HUGE difference between 85 and 95)...then it would be REALLY nice to know which engine we are talking about.

I'll just go with what you said last: 1995 Oldsmobile Regency Elite (Two engine possibilities)

If you have the 3.8L Supercharged engine (VIN CODE "1") it is on the left side of the engine near the oil filter.

If you have the non-supercharged 3.8L (VIN CODE "K") there are TWO of them. One is near the oil filter and the other one is in about the same location on the other side of the engine block.

Please also note that MOST fault codes for knock sensors are not caused by the knock sensors themselves. (they do fail, but it is very rare.) Usually there is either a wiring problem to the knock sensor, or the engine has internal problems causing a "knocking" or "ticking" noise which causes the engine computer to "think" that there is a problem with pre-detonation causing an "ignition ping". The code sets when the computer has retarded the ignition timing as far as it can and the "knock" or "ping" does not go away....usually it doesn't go away because it is not caused by ignition timing. The knock sensor is just doing its job and reporting the knock. It does not know the difference between a knock caused by ignition and a knock caused by internal engine problems.

I have a 2008 higlander - rattling noise at acceleration. OK on open highway - just at acceleration? Any thoughts?


Could it be low RPM pinking?
Try premium gas to check.
If that fixes it then you have bad gas, the wrong type of gas or the knock sensor has died or is disconnected.

1995 Ford Windstar Engine Knocking at startup. Driven 2800 miles since last oil/filter change. Oil level SAT, Coolant level SAT and no visible leakage. Engine completely rebuilt 2 years ago. Engine has...


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

Loud ticking noise


Ticking is generally associated with a valvetrain problem but may be caused by low oil level or pressure. Noise is in the upper half of the engine. Knocking is from low oil pressure and is caused by worn bearings causing pressure loss. Knocking is the worse of both conditions (means overhaul or engine replacement.) Ticking needs to be checked for it's cause...if cause is low oil pressure, remember...oil pumps don't cause low oil pressure, pressure will lost if bearings are worn or pump inlet screen is plugged with carbon.

1986 jetta oil pump location and replacement/knock sensor


oil pump is in the oil pan and if you have no or low oil pressure replace pump before doing anything with knock sensor. knock sensor is more or less a microphone and listens for spark knock but will set codes for any knocking or tapping noise which is commonly heard if oil pump is malfunctioning
