Question 1
what causes excessive oil consumption in my air box on a 1989 chrysler lebaron 2.5 engine non turbo?...  

Answers
1)   Oil consumption in your air box? Sorry, I think you're in over your head. - Robot

2)   turbo needs rework leaking/oil line for cooling and turbo bearings need to be redone - ken k

3)   Plugged pcv valve,worn piston rings or valve seats but more likely to much crank case pressure or pcv means positive crank case ventilation. - Scott W

4)   do you mean oil is coming into the air filter? if it is then check the pcv valve. - bandit_60

5)   This problem was quite common on these cars with the 2.0 and 2.5 engines. The crank case has to breath in and out or it will build up pressure and blow a seal or gasket. So to keep dirt out of the engine, it breathes through a polyester mesh filter in the air filter box and down through a tube attached to the air filter box. The 'blow by' of the piston rings forces crank case vapors to go to the air cleaner box and collect. The more blow by in the engine via the rings, the more oil collected. Make sure the vacuum hose at the PVC valve isn't partially stopped up. This hose also sucks blow by out of the crank case. Ok? - Jackolantern

6)   The most common problem would be blow by due to worn out rings in one or more cylinders. If you check you compression you will find that one or more cylinders is reading in the 60-70 PSI range rather than the normal 120PSI range. At this point I would guess you have about 135K miles on your 2.5 engine and it is due for a rebuild or replacement. I just went through this with my wife's Reliant wagon, although we had the 2.2L engine rather than the 2.5. I replaced it with a 2.5L though and am really glad I did! If you are short on money try using 20-50 oil unless you live up north in the snow zone. The 50 weight racing oil is also an alternative - both being thicker oils they will not run past the rings so fast, but won't stop nor cure it. I run 50 weight in my Jeep with leaking rear main bearing and it helps, I only have to add a quart every 700 miles with the 50Wt whereas with 10-30 I was going through a quart a week.

Start looking for another engine is my advice. - howard

7)   It's caused by being a 2.5 quite honestly. - Frankie Coletta

Question 2
I have a 2000 Chrysler Concorde. When i brake hard or just stop at a stop light the oil light comes on.?...  I just got my oil changed and everything. what would cause it?

Answers
1)   check your oil, if it's fine, i would take your car to an auto shop. - H.D

2)   ooooooh

either your oil level is dangerously low

and sucking air in the pump.

or your main engine bearings are worn from high mileage.

the light ......means zero oil pressure!

have that looked at very very soon.....and quit driving it till then.

Do Not Drive That Engine even to the shop with out making sure the oil level is at least correct.

That oil light is a very bad warning sign - "Not today, Zurg!"

3)   First check the oil level. The shop might not have added enough oil.

Second, the oil filter might be leaking and that would cause the light to come on.

Third, it could be a defective oil pressure sensor. I had to replace one on my Jeep.

Hopefully it will be an easy fix. - mindbender - seeker of truth

4)   if oil is full then most likely oil pressure switch or what many call oil sending unit cheap easy to replace - kelly_f_1999

5)   We had a lot of issues with these back then when they got around 50,000 miles and over. First off, there is a bulletin on the wiring going to the oil pressure sending unit which requires you to have a wiring 'pig tail' attached to the original one on the car for that problem. Second, that motor has an aluminum block with the catalytic converters running underneath both sides of the motor and causes the oil in the motor to run hotter than most. The combination of both causes the oil to sludge quicker than most motors. Changing the oil regularly at around 3 to 4 thousand miles keeps sludge at a minimum. You need to take it in to a Chrysler dealer and check for sludge build up on the oil pick-up screen and/or problems with the oil pressure sending unit wiring. - Jackolantern

6)   If it just started after the oil change, then check your oil level. The light could flicker if your idle speed is too low, from a dirty throttle body or shot tuneup components (spark plugs/wires).
Also, if the engine has alot of miles, it could just be losing compression. This would not be a sudden thing. - GTCturboII

Question 3
Bad Gas in my 2002 Pt Cruiser. I had someone put a can of very old gas in my car and now it wont start.?...  The car ran for one night after the gas was put in but now it wont start. I can get it to start with starting fluid but runs real rough and dies in about 30 seconds

Answers
1)   buy a bottle of fuel treatment and new gas - kelly_f_1999

2)   Most 'bad' gas won't run unless the engine is warmed up. The best way to solve the problem is to fill the tank with fresh gas, or at least add some to the bad gas to dilute it and go ahead and burn it out. - Jackolantern

3)   Try adding 3 cans or so of fresh gas and if it keeps dying after 3 or 4 tries with the ether your fuel filter probably got plugged up when it ran out of gas because it may have sucked rust and stuff out of the tank so check the fuel filter. Next check to make sure the fuel pump is working. - Jimbob

4)   Sounds like you have plugged up the fuel injector system. If your gas tank is less than half full I would strongly suggest buying enough gas to fill the tank and add a can of fuel injector cleaner. Problem is it is going to take a long while to get the old gas in the line out of the fuel injection system so that the cleaner and new gas can do the job. - howard

5)   You put in bad gas AND using starting fluid on a car engine. Step away from the car. - Frankie Coletta

Question 4
my pt cruiser's wheel jiggles @40-60 mph i have changed the rim &all tires balanced the whole 9 need help?...  now i hear a(metal) grinding noise when turning wheels ,the axle on that side (frt. pass)

Answers
1)   the axle shafts have cv joints and they can be loose or the car may have a bad brake caliper and that can cause it - ken k

2)   I suspect you have a bad axle. Check the joints at each axle, may be loose or worn. - C-Tech

3)   *pukes that you bought a PT*

Regardless of what the problem is, there's most likely a fairly cheap fix.
Get yourself an alignment, and if that doesn't fix it ask your mechanic.

If he/she can't help you, then you learned your lesson. :) - Steve

4)   alot of times, especially on the pt cruisers, the front hub bearings will go out causing a vibration and noise, get those looked at and also the cv shaft, but most likely the hub bearings will take care of your problem. - Brian H

5)   I'm not a mechanic, but had a simular problem with my 2000 Voyager. The brake lines running to the caliper have metal clamps to hold them away from the tire and they rusted, causing the fluid to not release from the caliper properly. Had the lines replaced and the problem went away. Since the brakes were not releasing all the way, the rotors were heating up causing the vibration in the front wheels. - Wayne

Question 5
'92 Chrysler New Yorker Radio not working?...  I recently acquired a new yorker with a non functional sound system I tested the radio in another Chrysler and it does function however in the new yorker i get nothing on the display and no audio. I have replaced the fuses. Any ideas on where to go from here?
The radio itself works. I tested it in another car. However any radio i put in the new yorker does not.

Answers
1)   get a new radio - Josh Timmons

2)   Check to see if you are getting power and ground at the radio connector with the ignition on. If not, and you have replaced both fuses, then you have a wiring problem. - C-Tech

3)   Of the 2 radio connectors, one will have a red wire at the very end of the connector. This is the hot wire when the ignition is on. The next is the memory and should be hot all the time. I don't remember where the ground is, but it should be black and maybe with a dotted tracer. Also the radio grounds with a bare braided wire on th back. All these have to be functional except the memory circuit for the radio to work. If the memory circuit isn't always hot, then the clock won't work and the station memory will go away when the key is turned off. - Jackolantern

4)   Sounds like the supply of power from the fuse box to the radio is disrupted by a broken wire or the ground connection to the radio is no good. Since you have replaced the fuse, it is obviously not the problem unless the fuse blew again. Chances are there is a break in the wiring or in the connector itself. Since you know the radio does work it is the only logical conclusion.

You need to check the voltage at the connector with a volt-ohm meter and make sure the ground wire actually goes to a good clean chassis ground. Don't forget to carefully look at the car side of the electrical connector. - howard
