My car spat **** out the exhaust that looked like oil, I could show you the stains on walls gates and other cars as it spat **** out very bad, Only when cold never when hot, But i seen little black dots all over the back of my car, When i gave it some foot it would blow smoke not always but it wasn't looking good, But it still ran fine oil was always good everything was fine but i couldn't work out why it was letting loose like that, I covered my sisters front bumper with **** once.
So anyway i just had my exhaust done, And i was given a option of Hi-Flo Cat for the price of a stock one, So i though what the hell lets get that done.
When they took the old cat off it was burnt out and blocked up with crap that looked like what was coming out the exhaust. they say you are meant to be able to see through the cat but you couldn't see through myn.
Since it's been changed and the exhaust also nothing and i mean nothing comes out my exhaust anymore no smoke no oil looking stuff nothing at all no black dots on the rear of the car nowhere. Lucky i didnt think my engine was toast and get a new one
.
Maybe you might have the same problem???
