Question about 2004 Toyota Highlander

1 Answer

My younger brother (46) has the above mentioned vehicle, but vehicle is using oil like crazy. It does not smoke when driving, but throws a smoke screen (heavy) when initially starting up, and vehicle is now firing on (5) cylinders. He took it to a shop, the mechanic told him that he got almost all of the cylinders firing (#6) will not fire and that is after a tune up. I told my brother based on the carbon/sludge build up I saw, that the PVC system could be clogged, and that he possibly may have some valve stem seals in need of replacement. I do not trust this mech. that my brother took his Yota too, as I was once an A.S.E. mechanic, and I know a hack when I see one. However, I have been out of it for a while and need some advise. Can you assist please?

Will a oil pump still work if the car dipstick reads way to much oil


Yes it will. An oil pump will never complain about too much oil. What the problem will be though is the crankshaft will be throwing crazy amounts of oil around and it may even be enough to get past the piston rings...... lots of blue smoke. Get the level corrected.

My vehicle gives out black smoke when i take off and press on the speed


Not knowing the vehicle and year etc all I can tell you is that your vehicle is getting too much fuel (too rich). That is what causes black smoke. Blue smoke is oil being burned. Have a mechanic check your engine fueling for being too rich. Some newer vehicles can only use regular fuel, this can be the issue if you're using a higher grade of fuel. Too many things to mention since you haven't supplied any info about your vehicle.

2005 town and country 3.8 using oil. no leaks 2qts every 3000 miles. any ideas please?


For that type of oil consumption there must be traces of smoke at some time. If there is smoke at start-up and when you lift your foot off the pedal to slow down, the valve stem seals are leaking. If the smoke is predominantly seem under acceleration and normal driving, the oil seal rings are allowing oil into the cylinder/s. At present the oil consumption and cost (if there is no excessive smoke) will be a lit less than the repair of either of the factors I have mentioned above. Try changing to another brand of oil (synthetic oil seem to contribute to high oil consumption). Try a heavier brand of mineral oil, at least a 20W-50 or even a 60 for older engines. Go for an oil that is marketed and backed by a reputable company with a petroleum back round.

Shutters smokes like crazy idles bad loss of


what color is the smoke if it is blue it is from oil which indicates a lot of oil is getting into the combustion chamber & being burnt which means you have a serious problem ( either rings or valve guides & seals) if it is black it is excessive fuel & you have a problem with the carburetor,maybe sticking needle & seat or the float has a hole in it & has filled up with petrol or fuel injectors which ever your vehicle has ...........cheershope this helps....

Engine is throwing out oil, as I drive, when stop grayish black smoke apperas


Hi There.

The question is where the oil is being thrown out.

When you park, is there an oil spot being left from a leak?

Is the smoke coming from beneath the vehicle (oil dripping on a hot surface) or from the tailpipe as exhaust?

The source of the oil leak needs to be located so the problem can be addressed

Best regards,
Mike

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.
