Hello to all. New to this forum. Hope everyone is having a great weekend. Anyway, I am from Glendale CA and I have a 2000 Civic SI. My car has about 132K miles and I used this for work, which is about 120 miles per day. I am also an active duty Navy, that is why I drive that far. The only thing I've done in my car is changed the headers and a short ram intake. Just wanted to ask if anyone can recommend a reliable engine overhauling shop here in Los Angeles. I think my catalytic converter is bad as I am consuming oil more than I should. I have an engine code and I replaced both O2 sensors already. There's no leak on the engine and I think it is burning oil as I have to add oil often. any suggestions will help. Thanks in advance.
