Sounds like lower end bearing damage (connecting rod) when oil level drops at interstate speed a connecting rod bearing will seize very quickly thus causing the bearing to spin in the rod and enlarge clearance . that is the knocking sound you here .

Check under the hood and inspect the valve cover gasket. If it's bad it would explain why you don't see any leaks on the ground because it's probably burning off on the manifold. This ticking you're hearing is a lack of lubrication to the rocker arms. Apart from the valve cover gasket, you should get under the car and inspect the oil pan and oil filter for seepage. Best of luck on your problem.

Check the Alternator / Powersteering belts .
One of them will be damaged and loose.
Hope this helps.

SOURCE: Loud ticking/knocking/rattling sound when I start/accelerate

hi is it miss-firing as it sounds like a knocking noise can be anything but if you can feel it on the accelerater pedal then the noise sounds like its on the inlet valve side which would transfere the noise up the throttle body where the accelerater is located it could be something as simple as a tappet come loose to a burned valve you need to have a look do a compression test and take the rocker cover off see if theres anything come loose yates210456

knocking in an engine is never a good thing. I'd check three things: engine bearings, valve lifters and timing chain, all of which can make noise. First thing though, is to put a mechanical gauge in place of the sending unit and check actual engine oil pressure. this will give you a good idea what is going on. low readings can be bearings, normal readings can be the other two items. I could give you a definite idea by listening, but I really can't hear it from here.!(one of the frustrating drawbacks to doing this online) An experienced tech can listen and tell you pretty much what's going on.

My problem is when driving, the engine rattles bad especially when accelerating, I had noticed my oil level looked empty


Most engines take at least 5 quarts of oil. Have you check the dip stick to see how much is in there?

By not having enough oil in the car, would that create a popping sound? Have a 2001 Grand Cherokee Laredo that was working fine and the next morning it started popping. Put it had one quart in and put 2...


If I understand your situation, you are saying the engine was run with one quart and you added 2 more quarts of oil. Now you have 3 quarts which is less than what it takes to make it full. On some engines it takes 5 quarts of oil. You will have to check the dipstick to see where you are now compared to the full mark.

If it is still less than full, it may cause some noise, but depending on how long you ran it with the oil low, how hot it got and other unknowns, you may have a serious problem. Try adding oil to the fill mark and pray that after you run it awhile the noise will go away. The noise may be the lifters trying to work with little or no pressure. It is possible that after the oil top off and a bit of driving they may pressure up and start working again.

The cars making a loud ticking noise when i press on the gas


If the noise gets louder with the engine rpm's, it is probably a lifter tapping. I would check the oil level. If it in low ( 2 or more quarts) you may be lucky and adding oil to the proper level may eliminate the noise. Good luck Dano

Checking oil and transmission levels


you will check the oil with then engine off. Pull the oil dipstick (yellow one) and wipe clean. Reinsert the dipstick and pull out. The oil level should be in the hash marks. If the level is below the hash marks than start by adding one quart and recheck. One quart will change the oil level from the bottom of the hash marks to the top of the hash marks.

The transmission fluid needs to be checked with the engine running. Preferably warmed up to operating temperature. With your foot on the brake engage the transmission through all the gears and then back into park. With the engine still running remove the transmission dipstick (red one) and wipe clean. Reinsert the dipstick and pull out. The fluid level should be in btween the hot marks. If it is low start by adding 1/2 quart at a time through the transmission dipstick tube. You will need a funnel small enough to fit in the tube to do this. It will take a while for the fluid to drain out of the tube. Recheck check the fluid level and continue adding in 1/2 quart increments until the level is in between the hot marks.

Loud knocking sound when giving gas or changing gears. Oil is fine.


the oil pump may be wearing out. The bearings in the engine could be allowing too much oil to pass through, and cause a low oil pressure around the other parts, including the camshaft or main bearings.

97 buick century, oil light started flashing, check engine light flashing car shut down on the interstate. what can i do?


Go check your oil first. If it is low or absent then you need to go get some! The car needs 2-3 quarts to get back into range at the least. Then try starting the engine. If the car starts and the light goes out you can drive to a mechanic and have the check engine code read to see what else is wrong. If the oil light stays on....call for a tow truck! You risk serious and complete engine damage if you drive any further...if you havent already!

Be careful and good luck!

My wife recently had the oil changed in her 2000 nissan altima and the next day it started making really loud knocking noise. my neighbor said he this car a had a "oil baffel" where the oil fill is located...


Most likely not. It can happen if they jammed a rod down there and poked around and did it on purpose.

Most likely you need to check the oil and take it right back to them if it is full or very near full. These places are known for messing up peoples cars after oil changes. I would go by the amount of oil in the car and mileage since the change.
If you only went a few miles say 50 - you should be able to show evidence it was something done or not done by the oil change people. If it is a comparative lot of miles and there are NO LEAKS of any amount much at all you should be able to get something from them if IF -- the oil level is very low or not showing at all.
If you wait 4 hours after driving the car - then
1- go pull the dip stick from the motor and 2
2 without turning the dip stick sideways or upside down
3- check the level and take a video pic if it is lower than 1 quart -
4 - take this to the people who did the oil change and if the level is low - do NOT drive the car without checking to see if the oil change people are stand up people.

Best of it

Burning oil, but dont know why


Nowdays 1 Qt. in 3000 miles, really isn't that bad, even some new vehicles claim that's normal. I know with my current vehicles, both at approx. 150,000-160,000 miles, they won't use any for first while after an oil change, but then after mileage starts adding up again, they start to use a little, approx.I Qt, every 1000 miles or so, until it's changed again. I've switched to the high mileage oil, just for piece of mind, as they say it revives seals, and has added protection for the higher mileage engines.This time around I'm thinking of adding "Lucas" & see how it works, as I've heard some pretty good reports on it, just to see if it will prolong that oil breakdown, at mid change.
