Hello,
I have a 1991 S4 Veloce in very good condition. I purchased it last spring and had an awesome summer with it. She is now off the road and stored for the winter.
When I purchased it, there was a little "wetness" in a couple of areas in the undercarriage and after looking at this board I understood that little oils leaks are common with these vehicles.
Over the spring/summer/fall I noticed about 2-3 new oil drops on my garage floor every week. Which seemed to be minor. The oil drops would show themselves under the transmission area and towards the back of the crossmember. No oil drops showed up directly under the engine. Most of the wetness seemed to be present behind the "Guibo" (flex disk) area which I had changed early in the summer. I also had the gear oil (Redline) and defferential oil (Spiax) changed. The mechanic who did the work said there is a small oil leak but this is normal for these vehicles and that I probably shouldn't spend a lot of money to fix the small leak.
The emmisions test on this vehicle was flawless. I did about 4,000 miles of driving this year and had to top up about 2 quarts of oil. Towards the end of this driving season I brought the car in to get the oil changed. After the shop drained the oil they said told me they did not have the oil I requested (Castrol GTX 20W 50). They thought they had it but the guy was wrong. We ended up putting in another brand of 20W 50 and I was off.
A couple of days after the oil change I stated to notice an increase in the number of oil drops in my garage floor (increased to about 10 - 15 per week - same area). It is still dry directly under the engine and the oil filter area is dry. I ended up spraying down the undercarriage to clean it up so that I can better see what is going on. I took some pictures of the area to show you what is going on and where the fluid is dropping from. I'm assuming it is engine oil.
If anyone can take a look at the photos and provide any advice on what I should be looking at, what the cause may be, etc. ... it will be greatly appreciated. Would different oils leak more than others? Should I replace the oil? Is this something urgent that I should be worried about?
FYI - I have circled three areas in one of the photos to show you where the fluid drops are. There is a droplet hanging off the transmission plug but I do not think it is leaking there. I have also provided an older image of the moist area behind the guibo (flex disk) which was taken earlier this year before I replaced it.
Any thoughts out there?
