My GF's dad is looking at buying this car. He lives in Il. so I cant go look at it. What do you think the problem could be? Here is the ad for the car.

I just bought this torch red 2003 cobra with 46k miles. Interior is clean, alot cleaner that i thought with it having 46k miles. Cleaner than most low mileage cars. The exterior is in good shape besides the bumper is cracked by the passenger side foglight and it doesnt have a spoiler, no holes in the trunk. The only mod on the car is a supercharger pulley. I received the car from the shipping company last night. Well the battery was dead and i started looking around and there was a fair amount of oil on the passenger side valve cover. I couldnt get the car started, plus the battery was dead as hell. I took off the intake and oil started pouring out of the valve cover. That right there tells me something is wrong. I dont want to mess with it. I just bought the car and probably going to take a loss. $13,000 No Trades. Will post pics later today. Clean Title
Im not 100% whats wrong with it, but there is no coolant in the oil. Worse comes to worse it needs a new short or maybe the seals in the supercharger went out, i dont know. There was so much oil dumping out of the throttlebody going all over the coil covers that where the oil could have came from. It has a pretty small pulley on the car maybe running too much boost on the stock supercharger and blew it. There is plenty of oil in the pan from what it says on the dip stick, its overful. I did get it running and it did smoke but couldnt tell what color since its cold out, not black smoke. When it ran it didnt knock or sound funny, Im assuming its a head gasket. I dont want to fix just want to sell if for what i have in it.
Here you go a little dirty from the 1800 mile trip

I'm thinking it was overfilled and blew the intake gasket or a seal in the supercharger but I'm not sure.
 
Also the PCV system could be letting oil in... That's what I never understood about Ford... Why vent the PCV system back into the intake side on a FI vehicle... That's a huge NO NO...
 
So you think it's sucking oil from the vc? So a bad head gasket then? I could tell him to start it with out the zip tube on and see how it runs
 
It is common to have oil in the throttle body area (and all over the blower/intercooler) since that PCV tube from the valve cover connects to the intake tube before the throttle body. However......there should not be a "ton of oil pouring out".

As for the seals on the blower......there aren't any. Just bearing cups in the rear that the rotors slide into but they only have a little bit of blue grease in them. The front gears are in a seperate area and there is no way the oil could get into the blower.......besides if it did it would go downstream through the IC then puddle in the lower intake. If you want to check that remove the small black allen head bolt and see if there is oil still in the rotor casing.

If you need a hand with something let me know......I should be able to help out.

No.....the PCV system is supposed to suck oil mist back into the vacuum side. Normal operation. The car will operate fine with or without the PCV system connected.

You also have another tube from the driver side valve cover but it goes to the rear of the blower (also vacuum side).

So could it just be a simple overfill? If the car wasn't in IL. I could go look at it and check somethings out. Thanks for the input everyone! +1's going around
 
Yea just remove the PCV tube and valve, looks like the oil is on the outside o the TB blade and PCV is the only place oil can get into the intake system as stated before about venting into the intake tube.

I say PCV Valve

Not likely......there is only one PCV valve and it is only on the driver side valve cover. The tube from the PCV valve ends up going into the back of the blower. The airflow and the slope of the floor of the Eaton is towards the rotors so oil would go down into the rotors......not out towards the throttle body.

True True

I should have known this :blush:
 
do a leak down test and check the pcv line for blow by with the engine running. Could have washed out the rings or broken a ring land.
 
Yeha maybe the car is just worn and torn, looks like to me that is has a smaller pulley on it. and an intake.
 
Thanks for all the replies. Just found out the car is sold so he didn't get it. It sounds a bit fishy to me about the car anyways. Guess this guy deals in these cars. So wouldn't he know what's wrong then??? That's what I'm thinking. Thanks again to everyone.
