Great amount of Oil Leaking

HTran · 04-17-2015, 02:08 AM

Okay so I have this crazy leak in the rear driver side of the car, it appears to be a thick dark substance that feels like oil, with a hint of gas smell to it.

The pictures attached was taken right in front of the rear driver side wheel. It looks like the oil is seeping from the fuel tank?

Mods are only JB4, chargepipe and bov. Mileage is at 130,xxx. automatic.

I don't have a jack to trace the origin of the leak, so it will have to go to the shop. Although its speculative, do you guys have any idea what it could be?

Check your oil filter cap oring. Start the car and check it your leaking around the cap.

Doubt its fuel, if you have the underbody panels on the oil could be pooling on the undertrays and blowing back. I would remove those trays and check the engine for leaks.

oil lines to turbos or vcg

Thanks for the input guys. I'm still wondering why I can smell fuel ever since the leak started to occur.

Maybe you have 2 leaks. You could be getting some fuel mixed in with your oil....oil leak.

Valve Cover gasket maybe? Known to fail...mine did. Easy to check.

Turns out to be some sort of fuel leak, and the oil pan gasket needs to be replaced. You are correct sir. Hefty bill, even at the indy.

First get the fuel leak fixed. Easy on the pan gasket. No need to hurry. The fuel washes the oil down that has gathered on the engine (over years). A good chance the oil well is not the pan. If it's the gasket actually just re-tighten the screws first and see if the leaking stops.

You were right. Nothing is currently defective with the oil pan gasket. I had to replace the whole gas tank, not sure specifically what the actual cause nor the proximity of the leak on the tank. Everything is good to go now.
