It's possible (see: VERY common) that one or more of the exhaust stud's threads in the head gave up... in which case helicoiling will be required. Hopefully, that's not the case. Did you tighten the nuts on the studs according to spec? 29ft lbs, IIRC? Did you replace the manifold gasket?
Our cars tend to run very rich, so when the car is still warming up you should check if the smoke smells like fuel. It sounds like an exhaust leak to me as well, the cause is all that remains and pulling the manifold back off is the only real solution. |
