Check the Seal around the Oil Pan Drain Plug. If this Seal is Missing or Warped it will slowly leak oil.

I recently bought a 1996 Lexus ES300. Upon purchasing it, I did a full service tune up (changed air filter, plugs, wires, oil, tires, brakes, and rotors). Everything seemed to be fine, as it ran...


Since you recently bought this car, did the seller inform you that the car had a problem? If they didn't and knew there was a problem (and 1-2 quarts a week oil consumption is something they would know) that is fraud.

Did you have oil residue on your plugs when you pulled them out and checked them? Which cylinders did you have the oil residue if any?

If you are burning 1-2 quarts of oil a week your tail pipe should be black if not oily. Is your car smoking badly? Have you considered doing a compression check to find out the health of your engine? I would if I was in your position.

Although you seem to be the handy type of guy, rebuilding an engine is not for the light hearted without a thorough mechanical background. Depending on your knowledge base and tool inventory and rebuilt engine might be the way to go.

Burning 2 quarts of oil a week but theres no smoke. All the gadskets are good and theres no sign of leaking I need to know how to keep oil in the car


2 quarts in a week is a lot. Check your positive crankcase ventilation PCV pipe (and valve if you have one). If the pipe is clogged or the valve is stuck shut then this could cause pressure to build in the crankcase and force oil vapor past the piston rings to be burnt. The amount is so fine per stroke you would hardly see it in the exhaust plume, this is not like worn valve guides where drips of oil cause great clouds of blue smoke. If the PCV is OK you need to have your engine dry and wet pressure tested to determine if you have worn rings

1999 1500 gmc savana wont start, it ran great, parked and now in the am it did not start...amp is good but oil gauge is low, we already add oil to it, it needed 2 qts...please help


May I ask how long since the last oil change? 2 quarts low is some serious oil loss. You are going to have to do some basic troubleshooting. Start by checking for blown fuses. Next, check to see if you are getting spark to the spark plugs. If you're getting spark, then check for fuel delivery. Do this by cranking the engine with the starter for a few seconds. Then pull one spark plug and see if it is wet with fuel. Let me know what you find and we will go from there. Good luck.

White smoke occasionally coming out of my Altima tail pipes.


If there is no loss of Coolant, which is a sign of Head gasket failure to the combustion area, which generates white smoke, I would recommend after 4000 miles of your mileage alone, a complete Service of Engine Oil and filter, AIR filter and Fuel filter.
An inexpensive way to find a recurring combustion problem, At 60k miles, the Spark plugs should still be good, but pull them anyway, just to confirm.

Blue smoke


Blue smoke is never a good thing....

Blue smoke is caused by engine oil entering the cylinder area and being burned along with the fuel air mixture. As with the white smoke, just a small drop of oil leaking into the cylinder can produce blue smoke out the tailpipe. Blue smoke is more likely in older or higher mileage vehicles than newer cars with fewer miles.
How did the engine oil get inside the cylinder in the first place? The car has many seals, gaskets, and O-rings that are designed to keep the engine oil from entering the cylinder, and one of them has failed. If too much oil leaks into the cylinder and fouls the spark plug, it will cause a misfire (engine miss) in that cylinder, and the spark plug will have to be replaced or cleaned of the oil. Using thicker weight engine oil or an oil additive designed to reduce oil leaks might help reduce the amount of oil leaking into the cylinder.

your engine has worn valve guides, piston rings An engine that burns a lot of oil (more than a quart in 500 miles) is an engine that needs to be overhauled. Normal oil consumption should be a quart or less in 1500 miles. Most newer engines consume less than half a quart of oil between oil changes (every 3000 miles). So if your engine is burning oil, it's essentially worn out and needs to be repaired.
Because the cost of overhauling or replacing an engine often exceeds the value of an older car or truck, many people will just keep on driving a "mosquito fogger" in spite of the blue clouds of smoke it leaves behind. Never mind the pollution it causes, oil is cheaper than a new or rebuilt engine they reason. That philosophy may be okay if you live out in the sticks somewhere. But in urban areas that require periodic vehicle emissions testing, an engine that's burning oil usually won't pass the test because of excessive hydrocarbon (HC) emissions. You may get by on a waiver after you've spent some money (in vain) on a tune-up, but the fact remains you're still a polluter.
An engine that burns a lot of oil will also eventually foul the spark plugs. Thick, black oily deposits build up on the plugs until they cease to fire. Then the engine misfires and loses power. Cleaning or changing the plugs may temporarily solve the problem, but sooner or later they'll foul out again.
Forget about "miracle" oil additives or pills that claim to stop oil burning. They don't. Better to save your money and put it towards a valve job and new set of rings.

Oil Change two weeks ago and oil level is low already???


I assume you have no leaks as you say. Your van does hold 5 quarts of 10w30 oil with filter change. The level was 1/4" above the add mark, which is less than 1 quart low. You drove the van 1,300 miles so it is very possible that it could burn that much oil in that many miles without you seeing much smoke. Top it off and have someone else drive it. Have them get up to around 60 mph, then let off the accelerator and let it coast down to 30 mph, then accelerate fully while you follow in another vehicle. If your van is burning oil you will see a big puff of blue smoke when they accelerate after coasting. If you do not I would suspect you were cheated out of about 1/2 quart of oil. You would not be the first person this has happened to. Top it off and check as I described and then check the level after driving another 1,300 miles. If it is still full find another place to change your oil as the place you went are crooks.

Lost engine oil: 2002 Ford F150 Supercrew 4x4 5.4l engine


This is certainly one of the strangest things I have ever heard as a mechanic. . This almost sounds like some one is playing a game of letting your oil out this vehicle. With no visible leaks no burning smell of oil. However I would recommend that you check the coolant in the radiator and see if the oil is in the coolant. (If they are mixing together) If they are mixing the coolant should have a milky look to it, creamish white. If its good then the only other logical explanation is that the vehicle i s burning alot of oil, but if that was true you would see a grayish blue smoke from tail pipe. If you are 100% sure they are no oil leaks on this vehicle, then this problem is surely strange. Check coolant and get back to me. Good Luck
