Using plain 30 or 40(or even 50 if the price difference ain'tbad) will usually cut down the oil burning

Thanks a lot.
I took it to Advance Auto Parts to get a diagnostic on the engine light. Their machine said I just needed an Oxygen Sensor.
A friend of mine told me that's just a scam to get you to buy a part that you don't need, because typically Oxygen Sensors don't need to be replaced. And ironically, that's the 2nd car I've brought to them to be tested, and have them tell me it's the OS. Your thoughts ?

[twa]

sometimes they can be removed and cleaned,but no I don't think they are lying

a car that burns oil plus your little oops is hard on them.

Check Engine Light on. Hooked it up at Advanced Auto Parts.
2003 Montero Sport ES 3.0. Codes are P0174 system to lean bank 2n and P0154 ckt no activity detected Bank 2 Sensor 1.
So the O2 sensor needs to be replaced? If so, the replacement part would be Denso 234-4738? (and not Denso 234-4741)

Thanks in advance.

Any way of checking? Is this a "at home" fix?

#1

Drain the engine coolant so that it falls below the thermostat level by opening the drain plug at the bottom of the radiator and draining it into a catch pan.

#2

Follow the upper radiator hose to the thermostat housing, remove the clamp with a screwdriver then pull the hose away from the thermostat housing.

#3

Remove the thermostat housing with a socket, extension and ratchet.

#4

Clean the old gasket off the thermostat housing and the engine with a scraper, using a light back and forth motion.

#5

Insert the new thermostat with its spring going into the engine.

#6

Position the new thermostat gasket onto the motor then secure the thermostat cover on top.

#7

Tighten the thermostat housing bolts snugly with the socket and ratchet. Do not over-tighten them or you will strip the threads.

#8

Reattach the upper radiator hose onto the thermostat housing and tighten the clamp with the screwdriver. Pour coolant into the coolant reservoir.

#9

Start the engine and check for leaks.

I havent checked it out yet, the wife was out running errands and called home.

She just got home a few minutes ago and says that she had heat while she was driving on the highway.

So I'm deliver pizzas over winter break and had a bit of a nightmare tonight...The Jetta that I drive is fairly low to the ground and I was driving on some road that was recently worked on. I hit some sort of awkward lump in the road that seemed to hit my oil pan. A few seconds later the oil light started flashing and beeping and my car had trouble shifting gears. I stopped the car and eventually got it towed. Obviously there was a fairly large puddle of oil where I had stopped. The place that I dropped it off at is closed till Monday. Just wondering if I could get any feedback here about what I could be looking at in terms of repairs.

[Capt. Kaos]

I'm Baaaaaaack!

Damned Impala again (2004):

The wife had the brakes and rotors replaced a couple months ago, within days of the replacement they were squeekin' and squeelin'. We took the car back and the fixed the problem. Well, it was fixed for about 3 blocks anyways. Took the car back in and they suggested we upgrade the brakes to ceramic pads, that would certainly fix the problem. So we did, cost an extra $100 on top of the original $325.

Bet you have guessed what comes next. It took a day or two but the squeeks and squeels have returned. Any ideas?

We are taking the car to another garage next week and I'd like to have some sort of an idea of what I'm hearing from them.

Thanks. Again.

When I turn the left turn signal on it either sticks on the inside (doesn't flash in the dashboard) or all 4 outside lights flash like I have my hazards on.

I believe this is a problem with my signal stat. Any help would be great!

Man, I sure haven't been keeping up with this thread like I used to. I'll answer as much as I can in reverse chronological order...

My first two thoughts would either be a bad turn signal flasher or a bad turn signal switch. The flasher should be cheap and easy to replace but the turn signal switch is probably a bit more expensive.
