Burning Engine Oil
I have a toyota corolla 2001 and its burning oil. There is no oil leakage as such but i have to put 1L every 1500-1800 Kms. Went to a mechanic, he told the oil seal(packing) around oil pan needs to be changed. I dont see any heavy leakage around oil pan. Also engine seems to be good and car has good pik up. No Black/white smoke after starting the car in teh morning and its 167300 on mileage .What can be the problem ? Can anyone help ?
check your coolent, see if it looks mily in any way, if so you might be leaking oil in to the radiator by the oil cooler, but that will also change the coler of the oil sometimes because water will be going in to your oil... is there any oil around the tappet cover? if so you may have a blown tappet cover gasket. try running the car till operating temp and then check the exhaust, smell it as well because it will have a smell to it if your burning oil. thats all i can help you with mate. good luck
so it only happens when it starts well then its the valve seals letting oil seep into the cylinder head.... this happens some times if you let your engine sit for like a couple months without starting sometimes even weeks without starting depending on the age and how thick the oil is....
my guess is valve stem seals, they're common enough on somewhat older corolla's, especially the e11 (or gen *) with the early vvti engine...they go hard over time and allow oil to pass into the combustion chamber, hence the increased oil used.
If you stop @ a light & then hit the gas... does a little white puff of smoke comes out? Answer: Valve Stem Seals. If the smoking is constant? answer: piston rings.
it's piston rings. very common with 98-02 corolla's.
I concur these years had problems with oil consumption. To be safe spray the whole engine clean with degreaser and a pressure washer, being careful to avoid things that shouldnt get that wet ie intake, electrical stuff etc, especially areas of concern. let it dry and then drive it for a few days and look for oil spots they should be easy to see this way you can remove any possibility of an external leak.
It's kind of a well known fact amongst mechanics that Corolla engines burn oil. Especially after 90K miles. A few posters mentioned it is just the design of the engine and I agree with that- Whether the "valve seals go hard" or the piston rings start leaking, etc... The freakin amazing part is, these engines are legendary for often going strong 300,000 or 400,000 miles or more without skipping a beat. So whatever the reason, I guess it is not something that hurts performance and engine life. I have a 99' Corolla with 140,000. Thing runs like a champ, not one problem ever with the car. Amazing vehicles. But it does burn oil. I put in 1 Qt per month approx. If I go on a long trip, I need to add a QT per every 1000 miles or so. No smoke or exhaust problems whatsoever. Passed emissions testing in N.J. which is insanely strict on their specs.
I have a 2001 with almost 300k on it. My wife noticed a little hesitation the other day so I checked out the oil as it was overdue and it was bone dry. I wonder how long it has been like that? Question, should I switch to 10w30, put an additive of some form in, or just keep an eye on it and top-up as needed? Thanks, Sean
sb_corrolla, stick to 5w30 and don't switch to 10w30. You'll have staring problems if you go to the thicker oil (especially if it gets cold in your region). My Corolla 2002 CE also burns oil... it has 150k miles on it and burns about 1q per 1000 miles freeway driving. I believe it's due to the fact that the transmission doesn't have many gears and the engine runs at higher rpms at 60+mph. The mpq is still impressive though - 32 combined... I just keep an eye on the oil and top-up as needed.
