Ok, so got a 1990 5.0, started it up one day drove for about 2mins started sputterin and imediatly white/blue smoke started coming out, drove it back home pulled a spark plug, and it looked like there was concrete on the spark plug i mean even a wire brush and alot of elbow grease didnt get this thing clean and these arnt old spark plugs, I checked the exhaust and even once I turned the car off it looked like there was smoke still pouring out of the muffler, I dont mean floating away I mean pouring onto the floor it was like it was heavy or something it was weird, I'm not sure if it was just old engine it had like 170k on it but I dont beat it, or if someone put something in my gas tank....and before the car was burning oil not too bad but enough.... really need some help here thanks....

Did all the spark plugs look like that? Sounds like somehow your car sucked in a piece of plastic or something like that? IDK

it dont take much, drop the gas tank and look in there, dump all the fuel out and replace the plugs, all u can do in under an hour.


but ur problem is soundin familiar, it could be that or a worn motor or gasket leak or valve seal leak

It might be your headgasket.Check your dipstick and if it's a milky brown oil ,i'd be getting that fixed.White smoke is a give away to that as well.
