This noob needs help! Mad Oil Leak!

[talonfreak96]

FIRST OFF im lossing 1qt of oil every 1500miles i dont drive aggresive. Ok i have been letting this go for a while but i need to fix it before i sale my car. My problem is i have a mad oil leak going on and i have know idea where. Im not burning oil. Its not leaking when parked. (no oil spots in driveway) So is there any place that that oil can odviously leak out of. To let you know the oil drain plug is fine, filter is fine, pan gasket is fine (replaced it when i noticed the leak) and know i do not know where its coming from.

Thank-you in advanced
Tony

If you're loosing that much oil the engine has to have an oily spot on it somewhere, or it's blowing out the back.

If it's the first, get some de-greaser and clean the engine off, that way you can pinpoint the leak.

If it's not dirty have someone follow you and see if it's blowing out the back. Sometime it is and you just can't see it for yourself being in the drivers seat.

If you're not getting any spots in the driveway, then you're likely burning it up. Could be due to some tired rings, but how long has it been since you replaced your PCV? They run less than $5 and can contribute to the burning of oil. You don't have to drive aggressive to burn oil. In fact, a lot of people experience more smoking at idle from worn valve seals than from driving aggressively, imo.

I'd also venture to say that a quart over 1500 miles isn't anything to be proud of, but if you're looking to sell the car, I'd just install a new PCV (maybe some new spark plugs too) and call ti a day. I've been going through a quart every tank of gas, the entire bottom of my car is covered with an eighth inch of sludge, and I still drive it to and from work every day without issue.

If there's no drips or smoke, the buyer won't even care. This is not a critical problem, imo.

It could be the infamous 420a leak. Check the rear driver side of the motor and see if its wet back there. I have this problem and the oil gets on the exhaust pipe and smokes just enough to smell it and not see it. I really need to cut that bolt down, this is my second HG in two years....
if it was loosing 1qt for every 1500 miles due to rings, he would be blowing noticable smoke.

EDIT: With my HG leak, I lost about the same as you are now, at its worst point.

 

[talonfreak96]

No it doesnt smoke at all and yes i did have someone follow me and no smoke and no oil blowing out. I bought the car with 140k miles on it and it has 190k miles on it now. I have not replaced the PCV. Actually if i may ask (yes im a big noob to the DSMs) what is that? and i have upgraded half the ignition a month ago. (plugs, wires, and coil) Yeah i guess thats true if the buyer cant se it he will not know. Well i was just wondering what it could be. ill try and get some picks of where the oil is coming from.

Thank-you

It a little valve (L Shaped) connected to a hose which runs from the Valve Cover to the Intake Manifold. Hard to miss.

and should only cost $3-$5 to replace, not to mention takes about 2 minutes to do. I love when you have to do something and it's easy.

 

[talonfreak96]

No i cheacked that and no leaks on it. Thatwas one of the first things i checked along with the head gasket, oil pan gasket, etc. OH i just thought of this. Is there some type of like oil sending unit or something like that?

The problem with trying to diagnose a oil leak is that there is a vortex behind the motor that will blow the oil onto everything, making it almost impossible to judge where exactly it is coming from. Take Jims advice and degrease the entire motor, then run it in your driveway and see where it’s coming from. The last thing you want to do is throw parts at it considering you want to sell it.

Oh and the oil temp sending unit is in the back near the tranny.
And another thing, have you checked inside the bell housing or around the harmonic dampener?

That's an oil pressure sending unit.

Good point about the crank pulley and bellhousing though. It could be your front or rear main seals...

I did the degreasing prosses and ran it for like 20min. Nothing. I think im only loosing oil when driving maybe? So there is a sending unit. If i knew where the sending unit, bell housing and the harmonic dampener was i would check them. I just goin into DSMs March of 06 so im still learning alot. Would those be in the Hyans manual? if so ill go out and get on tonight and put it on the my lift and check em out!

Thank-you and ill give some reps out

For god sake, no one tell him where the bellhousing, crank pulley, or sending unit is! That way he'll need to buy a Hayne's/Chilton's manual.

Seriously, you should have one of these manuals before ever touching your car. It should have all the necessary information in it for you to do just about anything.

Better yet, stop by your local Mitsubishi dealership and try to get a copy of the Factory Service Manual (FSM). That infamous piece of literature will have everything you need, straight from the source: Mitsubishi/Chrysler!

I would say your running stock exhaust...rite....I know the stock cat gets really hot and will dissipate smoke from burnin oil... I had a problem like this...Then dealt with it and just added oil. One day decided to remove my cat and then i sall the smoke...Would smoke at all times in idle....something to think about

Finally, some frustration from paul i love it.

He's only gonna get worse ...after hanging out with me in Florida over Christmas break, I'm sure he might be a little more into the e-thuggin


FYI: factory service manual

 

[poseclipse]

Dude, check your freeze plugs. Google it if you don't know what those are. Also check the intake manifold gasket between the head and the intake manifold on the back side of the engine. The only way you will be able to see this is under the car looking straight up the middle of the engine. Check the corners of the head gasket. If oil it is leaking on to the main support of the engine check the rear main; the gasket between the trans and the engine.

Edited for spelling and grammar. - V

headgasket=already mentioned

rear main=inside bellhousing=already mentioned

He mentioned the car was running so give him ideas that pertain to when the motor is running.

hey if you still are looking for answers to this thread please let us know where you checks have lead you so we can pinpoint your problem. gl

Hey guy Thanxs alot! Well i was going to finnaly put it in the garage and start searching. (got one of those hynes manuals ... good stuff thanx paul). Well friday night went out and some guy saw my car and was like so for sale huh ( no just thought i stick a for sale sign in the window ) Anyways i sold the car for $4000 now its his problem. Im driving the companies Mini Van till i find another DSM! Thanx All Again!

 

[4UH8ERS]

BANNED! for selling your 2gnt

 

[talonfreak96]

HAHA What?

 

[viperlp01]

hey man i would check you oil filter for a mistake. You could of messed up your gasket or forgot to take off the last one when you changed the oil last. That can really mess things up. It is simple and you'll lose like a surface on your oil pan of oil. 2 gaskets can mess things up. Try that thnx John

 

[viperlp01]

haha that is funny as hell he doesn't need a dsm if he can't find out what is wrong with his oil leak
