My cobra burns oil. There is a blue smoke coming out of the exhaust after I step on the gas and smells like burned oil too.
It's kind of weird, because it got only 6K miles on it. I am running Mobil 1 5w-30 synthetic. There are no external leaks in the engine and
it doesn't leak through the gaskets nor oil pan. Do you guys have a clue? What would you suggest?

P.S. My guess is it could either be the oil rings (unlikely because of the mileage) or valve seals. If the latter, how much to fix?

couldn't guess on a price. but that is odd for 6K. did you break the car in properly? or just start driving the **** out of it from day 1?

some puke mechanic at ford told me that you werent supposed to switch to a fully synthetic oil till your engine broke in at about 6 thousend miles...could be that but thats just a guess...said the synthetc was to fine and doesnt have the wax that other oil has so it can get between bearings and all that mumbo jumbo.

You can use synthetic from day one.

You need to run a compression check and see if you can pinpoint where the problem is. Sounds like you blew a headgasket.

mmm... not like it matters, but what year is the cobra? just curious.

Well for having 6k miles I'd guess an 04.

you'd be surprised. my mother bought her vette when it was 2 years old and it only had like 4,000 miles on it.

Sounds like warranty work to me. Take it to the Ford house.......

cobra is 99. I bought it from a millionaire who had like 20 cars. He garaged the car, so it was 2K when I bought it last summer. I thought the engine had been broken in, so I drove it hard couple of times.
