DAMMIT! Found a fluid leak in line right next to Oil pan...
Does anyone know what this line is?? The fluid is clear and somewhat slippery...I think its coolant but not sure...could it also be power steering fluid or something?? The odor isn't very strong...but it has a musty sort of smell. Its on the passenger side right next to/or around the oil pan. Any help would be appreciated before I go to the shop and ask them...
Oh yeah, everything seems to be working fine and the CEL isn't on.
Thanks.

Pics would help.
Coolant should be green (most likely)... could be oil or power steering fluid... hard to tell without more info.
Use imageshack.us for hosting pics... (if you don't another way to host).

After looking at the service manual, I think its power steering fluid...but that's just a guess. Anyway, here are some pics:
In that last one it looks like someone taped up the line or something. Any thoughts???

Actually there are two sepearate things going on.
The oil on that harness is mostly from whent the oil filter is removed (during a routine oil change). It's poor design - but that's how it works. Everytime you pull the filter, you'll get oil on that harness/tape - you can see the filter (white) in the last 2 pics).
In pic3, the harness plugs into the oil pressure sending unit. These are prone to leak and you can see that it is indeed seeping (oil stains all over pan). That part is 10 bucks and takes 5 mins to swap out - do it at the next oil change.
So based on those pics, you've got nothing to worry about.

Ya that line is just the wiring to the oil pressure sending unit (that controls the oil light on your dash). No probs waiting until the next oil change.. just keep an eye on the oil level - since you can't be sure of how much is really leaking out.

No, not really. A really good mechanic and autocrosser aligned and inspected it this summer and he feels it too, but he firmly believes it's because I'm running 225 width tires instead of 215. I find that hard to believe, but surely my next set will be 215s.
I'm going to change back to the stock SE springs (I have some Suspension Techniques 1" drop springs on Tokico Blues now), install new dust boots and coil insulators, and replace the shock mounts if necessary.

Hey, I haven't done anything since the leak only happens in the early morning (after the temp drops below 30)...but I don't think the leak is oil...its coolant. Any idea where this is leaking from??
#13
if it's coolant then I suspect it's coming from ur engine ... cause what I suspect is happening is that ur water pump is going out on u ... most likely the o-rings around it ... so check ur coolant level ... but I'm just assuming here, cause the same thing happened to me .... let me know how it goes

I think its coolant because its greenish and the stain "evaporates" after a full day in the sun...I thought oil stains were forever. I'll check the coolant levels tomorrow. I don't think its power steering fluid but who knows??
#19
Could be oil, P/S fluid, or coolant. If you think it's coolant, loosen the clamps on any hose near where the leak might be coming from and move them on the hose a little, then re-tighten.
If it's not coolant, it could be P/S fluid from your P/S pump inlet (same fix as for coolant), or your oil pressure sending unit, or where your oil pan bolts to the block.

You should just take it to a garage for a free estimate. It beats being stranded with a bad water pump.

Ralow, did you get this fixed? I am battling my own mysterious oil leak.
The lines shown in the pictures are the wiring for the oil pressure sending unit, and the one running under the oil filter goes to the crank shaft position sensor, located under the crank shaft pulley.

I never got it fixed cuz the leak stopped on its own. I checked all fluid levels and they are still fine. Not sure what exactly it was. I was just gonna wait until my next oil change and have them look at it since they will be down there anyway.
#24
Check to make sure its not the PS hose leaking fluid down on the line for the oil pressure sender. If it's the sender you will see seepage from the oil sender itself. My sender is dry so the leak is coming from somewhere else. Either a PS fluid leak or oil from the oil filter, etc. I think I will steam clean up there and look again for a leak. Also I just had my transaxles replaced. They may have screwed something up when installing the axles.
#25
if yourr leak was coolant, this happened to me last weekend....same leak in same place...pressure test was good and it turned out that the drain plug at the bottom of the radiator was loose and the coolant was moving along the top of the undercarriage and coming out where the water pump is...check that too.....

Newbie, you're SUPPOSED to bring up an old thread instead of making a brand new one.
As long as the OPS isn't leaking, you can drive it for a while.

If your coolant is leaking only in the morning, it could be the water pump, mine did that and it drove me nuts until I got it fixed. If you let it ride you'll notice that you are going through alot of coolant. I say get your water pump looked at and replace it b4 you put the equivalent of its price in coolant.

The guy who started this thread should have his problem fixed by now (a year ago) but for those reading the above post, PLEASE don't always assume the water pump is the culprit when you have a coolant leak, because if you do (like I did) you may find that it is a gasket somewhere else, like on the engine block. Have it pressure tested--do it the right way.
And for the poster who resurrected this thread, don't drive long on a bad sending unit (OPS/OPSU). If you had a leak or developed one, the pressure sensor (being faulty) will not notify you of low pressure and you could end up with serious damage from the leak.

Man, this is OLD! I was just browsing and came across this again. Anyway, I had the dealer look at this issue when I had them do the 105K service last May and they said it was just the oil sensor. They said that part is notorious for the "slow leak" in older cars but its no big deal and that you could drive around as long as you want cuz the leak is so small that it will never be an issue as long as you change the oil regularly...it will just stain your garage with little spots. Anyway, they said they could replace it for like $70 bucks....but I just laughed and drove right to Autozone and replaced it for around $20 including oil, filter, etc. (I waited til my next oil change BTW). I think that sensor cost $7 or something...I could be wrong but it definitely wasn't more than $12. Either way, I just used the instructions here:
http://www.motorvate.ca/mvp.php/514
and was done in 30 min. I also had to do an oil change since the oil will drain out when you replace this part.

seems like the culprit who bumped it....we all followed suit with the original question.........or at least I did
