Unfortunately, the damage is done--the crankshaft bearing(s) have probably been ruined for lack of oil along with the pistons, rings, camshaft, valves, and so on. A major, major repair. Even if you fix the obvious noises, the rest of the engine will continue to haunt you. Cheapest repair is to find a replacement engine at a wrecking yard--they give a short guarantee for such parts which is long enough to reveal such things as oil burning and noises like you have now. A re-manufactured engine is the best of all choices, but quite expensive--probably over $3000. Hope this helps!

Did you suddenly loose all oil as well? Once you loose all oil pressure you must shut engine off IMMEDIATLY to prevent major engine damage.. How low is oil now? If very low and you really lost all pressure, engine may be junk.

Oil light never came on, I decide to put 4 quarts due to it being 10 months since change, since doing so low oil light has come on


4 quarts means that youve got one serious leak and your slicking up the roads for every body... you should get out some tools and see what you can snug up to slow the leak, as for the light, your driving a cheap vehicle so what do you expect ?

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

Transfer Case Oil Change-2003 GMC Sonoma


has your transmission oil been low? only reason i ask that is you said it acted like it was pressurized i have seen the rear seal on the trans go out and overfill the transfer case before. you never want to fill it over the fill hole. so if it held just over a quart that is what it takes. but there is still the question as to where the other fluid came from my guess would be watch for the trans fluid to be low.

2007 rabbit - oil light


If it was still running okay & no noise, probably no engine damage. Adding 2 quarts should have turned off the light if the problem was oil pressure. Sounds like the oil pressure sending unit may be bad.

Transmission sliping


I am willing to bet that the clutch packs went out since it was that low on oil because there are 2 pints in a quart and that is a lot of tranny fluid to be down i am going to say you need a rebuild on the tranny

If you feel a difference in the vehicles performance it's probably not the sensor. Change the oil, and filter. Check the oil for metal flakes, shiny specs floating in the oil. Fill it back up one quart short. Add a quart of transmission fluid. Tranny fluid is a detergent, it will help clean any blockages and build up. Drive it for a week. Then change the oil again. If that doesn't fix it, you might have to drop the oil pan and clean that out. There should be a magnet in the pan. This collects metal that will harm your engine. Make you you clean it and put it back. Check the oil pickup, remove it and clean it out. Once you drop the pan, you will have access to the oil pump and it's sensor. Check them out to.
