I HAVE A 1995 CORRADO. THERE IS A SMALL OIL DRIP WHEN I MOVE THE CAR OUT OF THE GARAGE AND LEAVE IT IDLING WHILST I SHUT THE GARAGE. NO EVEIDENCE OF A LEAK WHEN THE ENGINE IS HOT. IS THIS A CONCERN AND WHAT NEEDS TO BE DONE TO RECTIFY IT
Country: United KingdomMake: VWModel: CORRADO VR6Year: 1995
GARAGE SAID REPLACING SUMP PLUG WOULD WORK BUT THAT HAS NOT WORKED
Hopefully i can help..
First off you'll need to ensure fully it is in fact engine oil and not any other type of fluid for example power steering / brake fluid / transmission fluid etc..If in fact it is engine oil then the only best way to actually track down the leak properly is to try and trace it back to which ever point on the engine its leaking out from and that can be in some cases the most time consuming part if access/space around the engine is quite restricted unless you have mirror/good torch etc..ideally you'll need to get under the car and see where exactly the leak is coming from and clear up as much of the present leak as possible with a cloth/de-greaser etc and only then you'll need investigate further and or at least trace it back to where ever its seeping out from if the leak starts to re-appear.usual places are either a failed sump plug washer seal or damage threads / rocker cover gasket seal - leaking oil sump gasket seal or the sump is porous or has small hairline crack / crank case breather or other oil lines are leaking / oil filter or housing seal leaking / or the headgasket - you can check this by following the seem between the head and block or just under you manifolds and see if you can spot any oil leak from there - also check around the transmission just to be sure the leak isn't actually from that too..but thats about the only forward to actually figure exactly where this leak is from and only then can you take steps to rectify the problem...
