Jeep oil leak

Question From rayritten on Jeep oil leak

Hi all I have a 2003 Jeep Liberty.3.7 V6.I noticed a oil leak after last oil change and can't fine it?Its leaking rear engine and I think moving down my Oxygen Sensor line on to the Sensor and burns off...While I drive no leak,after I let sit over nite there is alittle on the exhaust.Not alot but stinks.I checked valve covers and fine,rear seal also looks good.I was told Crankshaft breather may be problem?There in a tube thats right next to the Transmisson drip stick.Looks like vaccum with white spring loaded top on it with oil all around it?Any ideas?

Response From cory89

Ray ritten...... I just bought 03 liberty and I have been chasing the exact same leak as u have. I have changed both valve cover gaskets. Replaced my pcv valve and iv degreased the entire motor and then used the uv dye and I im coming up empty handed. Did u ever figure it out?

Response From Tom Greenleaf

Cory - Please start your own new thread not a 2+1/2 year old one that isn't your exact anything.


This one locked for archives so please start your own,

Response From Tom Greenleaf

Did you do the oil change? Either way if this happened right after one hurry and recheck oil filter and drain plug. I suppose by chance an oil pressure sending switch could do this but you or someone should find it whatever it takes to isolate this.

What the heck is "Crankshaft Breather?" A pcv hose might be the issue or a pcv itself isn't installed properly,

Response From rayritten

Thanks for the return,I did check PVC hose and PVC which are in the front of this year model.No leaks.And plug and filter,no leaks either.There is a breather plug for the crankshaft sensor and I think there called the samething?Part of the Emissons system.I agree all this because something wasn't done right?Never had a problem like this before..Thank again my friend

Response From Tom Greenleaf

Just know it's your engine at risk no matter where the source is. If this went nuts and leaked out fast and you didn't notice it's the fastest way to destroy an engine. As said, it needs to be found without fail,

Response From rayritten

Oh yes I know that,just wanted to see if anyone had any idea's before I take it in and go in blind,know what I mean..They can say it's anything from Seal to Head gasket and what ever cost more I'am sure they'll try lol Can't trust anyone anymore sad to say...Thank you again Tom

Believe it or not, not every shop is out to screw their customers. We simply are the bearer of bad news. A few bad apples taint our reputation. On this site are nothing less than certified techs, dealer trained techs and shop owners. The very people that are accused of scalping the wallet of the working man. The cars today are built with way more expensive parts and much more complicated systems that require an immense amount of knowledge to diagnose. To diagnose them, we have to buy tools that cost way more than the car you brought to us to have fixed. So don't point the accusation finger to fast. This isn't a board of shadetrees here and we've all invested more in the tools it takes to fix your jeep than you ever paid for it. You will get professional advice for free, and we charge for it on the job. Even David Copperfield won't show you where the rabbit went.

Thanks Nick for your come-back.I do understand the cost and what good shops have to deal with.No way I would group all shops sameway.And as far as finger pointing I wouldn't point at all unless 100% sure of why the pointing?I think this board is great,one of the reason's I do post and have told others what good advice is HERE.Sorry if I offended anyone,but simple facts are,there are way to many that do try and rip people off doing work unneeded..And I'am sure most that do try and take advanage don't really come here anyway...Sorry again if missed understood...

No - for years I find this trade is no worse than any other. Bad shops or worse telling you work was done and did nothing don't last long,

Can low grade fuel fault an O2 sensor?

Showing 3 out of 12 Posts | Show 9 Hidden Posts
Question From Bort on Can low grade fuel fault an O2 sensor?

My experience as a mechanic is building dragsters and formerly working as a heavy wheel diesel mechanic (strip mining equipment). So I have the skills needed to fix things myself but not all of the knowledge I'd like to have about newer combustion engines that run on gasoline and the electronics stuff in every-day passenger vehicles.

My 05 Jeep Liberty, again. Inspection is due. Engine light has been on for a week so I ran codes and it came up as bank one 02 sensor. I ordered the part, nobody local had it in stock, and a week later the light when out so I re-tested and...no errors. When the fault code was there I did have lower grade gas in it, and the light has come on before when I used very low grade gas but went off and stayed off when it got to high grade gas again.

The next day it went on again and it's been on since then. Could the grade of the gas I'm using cause an oxygen sensor to fart like this? I'm replacing it anyway. Just asking. And if my thought is correct that it is possible would using gas treatment help clean them off and prolong the other 3 sensors life span?

Response From Discretesignals Top Rated Answer

You shouldn't replace anything just because it is mentioned in the code description. Test, don't guess.

Response From Bort

I was considering testing before replacing as D suggests but I have the money and don't know when they were replaced last. So I decided to just replace it although, yeah, it could be the wires aren't connected right or the air flow is clogged?

The codes are high and low voltage errors. I could be wrong and can accept that but if it wasn't communicating right the error would be different, right? It would say it fails to respond or something? Not that it's throwing wacky voltage?

I haven't read the entire oweners manual page to page. I'm not sure it does specify what grade of gas should be used. It might, but then also as most owners manuals suggest, it will probably say the highest you can get.

I learned it doesn't like low (below 89) grade gas from driving it. I put 87 in it one time and the engine light came on when I got below 1/4 of a tank. I ran the codes and nothing came up so the next time I got gas I put the highest grade I could get in it and as soon as that remaining 1/4 tank of gas expired....light went off.

Response From Tom Greenleaf

I could be wrong on the octane grade suggested that you found but haven't seen a vehicle yet that didn't clearly mark at the fuel gauge that it requires usually premium vs regular we think of as 87 rated Octane. I've never seen a car/vehicle suggest 89? I have seen 2 stroke weed whackers suggest 89!


Most all engines I've seen requiring other than regular are higher end and more performance vehicles that a Jeep!


T

Response From Bort

LOL! Weed whacker.

I'll check the gas cap to see if it says anything. This is my primary vehicle that I drive daily, several times a day. Nobody would knows it's querks better than I do. Every vehicle no matter what type of vehicle it is has it's own little querks that it's owner or primary operator learns and figures out how to compromise with or do a certain way to keep their whip happy. It doesn't like lower than 89. Engine light comes on if you put lower than 89 in it.

Even mechanically challenged people associate 87 grade gasoline and lower to be low grade, 89 to be premium, and 90s or above to be high grade.

I could also be wrong too but I don't recall ever seeing a gauge stating a grade requirement. They just say Unleaded Fuel Only for gasoline engines. Maybe the gas cap might say differently. I'll check all my vehicles including motorcycles and weed whacker. I'm curious now haha!

Response From Hammer Time

Are you going to give us the code numbers?

This vehicle calls for 87 Octane unless you are towing so forget the fuel idea.

Response From Bort

It was both high and low voltage error codes in bank 1 sensor 2. I don't know the actual code numbers.

If I put anything lower than 89 in it the check engine light comes on. Poor fuel quality. Towing or not it doesn't do well with poor quality gas. A person learns these things about their own car that they drive every day. Thanks for the help.

Bank 1 sensor 2 location: Drivers side after the cat. Easy to get to.

Response From Hammer Time

You may think it's the fuel to blame for that but it is not. We need exact code numbers to be able to help you.

Response From Bort

I don't know the codes. I didn't save or memorize them and can't reproduce them because that issue isn't present now and I've learned how to avoid it - use high quality gas.

My question as to whether poor quality gas will cause an 02 sensor to throw a code was answered. No, most likely not. I wish I knew what could be causing the light to come on then but...problem solved. Question answered. Appreciated!

Response From Hammer Time

OK, I guess that means we can close this now.

Response From Hammer Time

There are literally dozens of different codes referring to the 0/2 sensor circuits and most of them are indicating something other than a bad sensor. We need the exact code numbers to help you.


To answer your question, no, the fuel grade will not damage a sensor. Incomplete combustion or other contaminants with ruin a sensor.

Response From Tom Greenleaf

What grade are you using or did use and what does this vehicle call for if not plain "regular?"


Codes that pin down which sensor doesn't mean replace that sensor but rather it's not communicating with the whole show so there's a problem in that circuit. No code tells you exactly what to toss to fix something. Just unplug one and you'll get a code and sometimes that's the problem and ignoring it causes more. Staring at a CEL with no quick action frequently will domino to need a lot more than the original issue.


If same code came back to same sensor it about certainly wasn't the up front problem and needed to be diagnosed a bit more before just tossing it. Anything that causes and engine to not run right on the way it was intended will be hard on exhaust items like O2 sensors and converters(s) up to ruining them.


Whatever "improper" grade fuel you think might have caused a failure if it did at all isn't likely to be solved by some magic in a can now or nobody would need to fix much of anything would they?
