Having problems with your Honda Prelude ?
I have blue smoke coming out of exhaust. . everyone's telling the rings are going bad in the motor and I should get rid of it. Could it be from a clogged catalytic converter? The guy who works on car tried to "unclog" the junk in the catalytic converter, he did not replace it. Could there still be some residue in there that's causing the blue smoke? Yes , it eats oil, but it has since I bought it three years ago and the blue smoke has been happning since last fall but it's getting worse, also in
The blue smoke and oil consumption is because of the bad rings. They are allowing oil to get by into the cylinders and it's being burned with the gas. If you don't want to put the money into an engine rebuild, you can try one of the many additives available at auto parts stores that claim to help restore compression and reduce oil burning in worn or high-mileage engines.
If the cat were cloged you would have performance loss but not smoke. Burning oil can be caused by a few different things. If the rings are going bad eventually you will need to rebuild the engine $$$. Oil may have contaminated the O2 sensors causing the car run rich = gas fumes.
