Question about 2006 Chevrolet Aveo

2 Answers

I have a slight oil leak on my 2004 chevy aveo, 115,000 miles. while doing a oil change, just to the right of thevoilnpan is a sensor I beleive with o nut screwed into it. Well I cleaned it real well and noticed the whole passenger under belly is coated in old oil. Needless to say after cleaning that part, I beleive that is where the leak is coming from. What is the name of that sensor, any suggestion would help, thanks.

That could be a knock sensor or it could be the oil pressure sensor.

SOURCE: 2004 aveo timing belt broke, all valves bent

just go to any junk yard and find a used deawoo lanos and pull the head if timing belt was not broke, if it looks good, its a exact fit 100%, no special tools needed, just normal wrench set and torqe wrench. after head is installed, get a gates timing belt only.

SOURCE: how do you change an oxygen sensor on 2006 chevy aveo

There is a special socket for O2 sensors which allow the wires to stick out and not get twisted up. It's not expensive and available at most auto parts stores. Disconnect the sensor from the wiring harness, with the plug and then use the socket to remove and replace the new sensor. Re-connect electrical plug.

Burning Oil


we check oil every other fuel fill up. on old cars, every fill up
did you run car 10,000 miles to a oil change? unstated.
1qt/3000 miles is perfectly OK.
so 10000 mles is 3.3 quarts burned and off the top of the dip stick
if you drive fast, it burns more, got a heavy foot, or load in back>?
if you had done it right, you'd have already learned YOUR engines
consumption rates, and learned to check when IT , needs checking
we do this on all engines. all machines.
all engines burn oil, the exception , a church car, new, and never driven, far, or fast or for 10000 miles to an oil change.

your mech, was right, he was thinking , you dont check oil?

My 03 Maxima (3.5l 255 hp) started burning oil at rate of 1 qt per 1000 mi. One guy at the dealer says this is normal, just keep adding oil, other guy at dealer says 'time to get a new car." Either way, it...


1qt per 1000 miles isn't too bad, all things considered. There is probably some leakage through the piston seals, which is to be expected after 115,000 miles. I would give a good quality leak-fix in a can a try, as they can really help with some of the more minor leaks. If it is a piston ring or seal problem, its an expensive fix, but give a canned solution a go to see if it helps.

Another option that a mechanic friend of mine suggested for my old Grand Am was going from synthetic to conventional motor oil. Synthetics don't generate sludge or buildup, which is great, most of the time, but when mine started to leak oil and smoke on startup he suggested going back to conventional, as some of the buildup would actually help stop the minor leaks.

Tune up


At 60,000 you should have all the major things done if you haven't already:
oil change(every 3000)
air filter change(every 15,000)
coolant flush(every 30,000)
spark plugs and wires(every 30,000)
transmission fluid & filter change(every 30,000)
brakes (as needed)
PCV valve (every 20,000)

You can wait until about 75000 miles to do your timing belt.

Hope this helps
