quarter size oil spot on garage floor...

[rah]

Hello all,

I guess i should of posted earlier about my 2003 RS6 when i first started lurking around this site a few month back, but i guess i will start with a problem, hopefully minor. I picked up my RS6 last September and i love this car. It has 82,000 miles on the clock, and everything needed done on the car was completed right before i picked it up, including timing belt replacement just to name a main one, every receipts included. I do not drive this car daily.

I noticed a quarter size oil drop on the garage floor, driver side, front of the engine. this is the second time it has happened. I removed the covers and did a visual inspection from where it could be and could not see anything anywhere. Obviously, i am sure i can't see everywhere and could be missing it, any ideas from anyone? anyone ever dealt with that? The interesting part is that when the car just sits in the garage for a week or two, no sign of oil anywhere, but when i use it for a day or two and park it, that's when it occurs.

It could be nothing much at all but i would like to address it ahead of a possible bigger issue.

Thanks for your time!

Belly pan present?

What kind of oil - engine, power steering, transmission? Connections for all of those are present in the left front of the engine.

Ah sorry, i guess i should of specified, but from the feel and what i saw it seems to be motor oil. My belly pan is actually NOT present, that was the one thing that was not with the car and that i am still hunting for. I did clean it now and the car has not been driven yet again. I have the day off Friday and going on a drive, i will check again then to make sure.

you definitely have to address mdegracia's questions (on what type of oil) but my initial thought, if it is engine oil would be intercooler hose is not properly seated and the oil accumulation at that low point is leaking.

Thank you, i will check on that Friday, that's a good possibility for sure.

All right, a local RS6 owner! I am right up the hill from you on South Hill!

Nevermind, you are not down the hill from me, just realized you said near Eatonville, i was thinking Orting for some reason. Either, you are not far from me, im at the end of South Hill towards Graham.

I've got the answer, Audi

But seriously, the auxiliary radiator lives there, one on other side too, and they like to corrode/crack/leak. Coolant should be red though. Also could be oil buildup in your intercoolers, and then leaking out.

Very true, i actually visited a local shop (Addiction Motorsports) and they did mention that the intercoolers after a while do cumulate oil and do leaks. Thank you for that, i'll try to check on that soon.

A couple of years ago I poured a cap full of oil on the floor under my friends heavily modified Subaru WRX STI and gave him an oil leak, he freaked out....could be a joker messing with you....

JK.

Oil pain seal. Only one bolt is a bit of an issue, but otherwise easy to replace. Run your fingers over the areas on the engine (cold engine) and may be able to pin point the source. After spending 15k on an engine pull I wonder if I should have kept driving the thing and just add oil every week. LOL.

That's a pretty funny prank lol. When i purchased the car, the shop that i purchased it from did replace the timing belt and all that goes with it (water pump etc...) and adressed a oil line leak as well as the oil pan seal. they replaced all that but you never know. I will double check on that as well just to make sure. After 15K, i bet it lets you wonder lol, but they are such great cars, always puts a smile on my face every time i get in it!

Only a quarter size? Sounds like you're well within factory spec!

Bingo! Check often. Keep wallet closed tight.

Yeah...I was thinking wait until it's the size of a Frisbee, then sell the car...

It took me a while but i finally got to take the car somewhat apart and got to take some pictures. By doing that, i think i found the leak, from the driver side valve cover gasket, front lower corner and perhaps the back of the same valve cover gasket as well. I posted some pictures. There is also oil that is dropping on top of the intercooler hose on that side (that is why i am suspecting the back of the valve cover gasket as well), which makes me wonder if the intercooler is also going bad and some of the oil is actually coming for the intercooler itself? What do you guys think? The passenger side intercooler is dry, just FYI. Either way, it looks like i will have to get a new hose, it is soft and not in the best shape at all.
