Well, in regard to the smell, I had noticed this morning that after starting my cold engine, I had vapor coming from the exhaust manifold crack. Before I wonder any more, I'm awaiting parts to remove and weld my manifold. As mentioned earlier, when I removed the fuel vapor hose going into the canister, I had noted that the fuel smell was definitely more 'raw' than what I am smelling. The exhaust leak may very well indeed be my issue, however how it is getting to the opposite side of the engine??? well, we'll just fix er up and see anyway. I'll update the results. |

I will definitely check AutoZone. The vapor hose has some braiding, but not as much as the pressure hose. Thanks! |

If you can weld the exhaust manifold yourself I say go for it but if it is costing you any labor then you would be better to just pop for a new manifold. The likelihood of a welded manifold lasting is pretty small and a new manifold is less than $75. The expansion/contraction is a killer on dissimilar metal bonds. Good luck with the repair. |

Do you know if the aftermarket one's on sale on Rockauto have similar cracking problems? I have my own welder, so there won't be the labor cost. |

What sort of welder do you have? Welding cast properly will require Ni rod and a stick welder. You will have to preheat the manifold with a torch, weld it and then maintain torch heat on it allowing it to slowly cool down. Even then the success rate on an exhaust manifold would be pretty low. They are just a very difficult thing to weld because of the heat cycles. Do a search on here for cracked exhaust manifold and you will find a pretty low rate. Not a big problem. |

Ya know...I flippin' forgot about the damn thing being cast. Grrr. They had a kit at Rockauto with the manifold, gasket and bolts... Everything I just purchased separately. I just have a mig welder. That isn't going to work well. |

I'm having a very similar issue... A gas smell while I'm driving and it's real heavy when I stop, shut the engine off and first step out of the car, but until I walk around and open the hood it's gone... I did notice the top of my butterfly was wet with gas, but even putting my nose directly over it isn't as strong as the odor inside or when I first step out... It also seems to come and go... Was there ever a solution to this?? |

Yes, I found the solution... kinda. My daughter started driving the car when she turned 16 in July of 2013. 4 months later... she burned the #2 exhaust valve and I had to pull the head to fix. From then until now I hadn't paid attention because my son turned 16 18mo later and continued use. Now that I just worked the car recently, I noticed no smell, so something must have fixed itself. I guess. |
