Dear list Thank you for helping me all the time, and it happened again... About two weeks ago while I was driving on Rt1, NJ, all the sudden I began to smell exhaust gas in my delorean. After that, I ordered 5 pieces of exhaust manifold gaskets; all the exhaust studs nuts and washers from the Volvo dealer. I was afraid to break rusty exhaust manifolds, so I simply asked the local shop to do this job by 6 hours job. However I still smell the Exhaust leaks. Each time I started the engine. When I get high rpm like 4000-5000, the gas become a strong smell. Should I replace a Manifold Heat Stove and Heat Stove Duct also? or should I dout the local shop? Could any one help or advice me please. Thanks again. Blacknight
