Honda Odyssey 2004 minivan 172000 miles
Engine do start but followed by a thick dark smoke out from the exhaust pipe, feels like it's on fire. Hesitates so badly that the engine and the whole hood shake. Tester indicated that all six coils fail to fire. Found timing belt oil soaked. I'm not sure where the oil that soak up Timing belt is coming from. 2 auto repair shops recommend buying a new engine, but this engine still stars though reluctantly. I fear that the oil contaminated T B might jump & cause damage to other Engine parts so I don't try to drive the Odyssey. Any help will be highly appreciated, please.
