There is this nasty trail of oil that lines up on both sides where I park my car in the garage. It is sprayed all over the back wall. I'm not sure that it's oil because it comes out as just little dots and not a puddle or anything. It didn't show up until the other day when I made a video of my exhaust, so apparently it only does it when I rev it a bit. Not at idle.

might just be water mixed with some carbon(both are byproducts of combustion)


any smell to it?


and if it is just water, it won't do it after the exhaust is good and hot(then it will be water vapor)

In cold weather, a lot of water condenses out of the exhaust gasse, and pupples in the pipes and muffler(s). There will usually be a bit of carbon buildup in the exhaust, and when you mix the condensed water with the exhaust, you can get a spray of sooty water out of the tailpipes. Could that be what you are seeing?

Alternatively, an engine that is running excessively rich will put a spray of wet carbon out the exhaust tips, but that's going to smell like fuel.

This is the case w/ my car. I had to line the back wall of my garage w/ cardboard boxes so that I would not ruin the wall. The stuff spray's every where; and it smells like straight gas. What would be the best way of fixing the rich problem?

Theres a number of things that could cause it, leaking injectors, bad o2 sensors, I once had a dodge van that the throttle body cracked (tbi) and leaked gas directly into the engine. Asking how to fix your car running rich is a very vague question, you should start by getting it scanned...
