Hey to all of my addicts out there. I got to say Im getting a bit worried about my use of these forums. Im somewhat of a new member and I can't keep myself from logging on and watching the time go by on these forums. This thing is very informative and addicting. Anyway, and on to my question: I have my mechanic re-installing my Weber DGV conversion due to an intake air leak and upon disassembly he found a crack in the exhaust manifold. It's about an inch long and runs from the edge where the rear mounting stud is. Immediately he asked to buy a new header from Moss and I agreed but after seeing the crack I start to wonder if it was necessary to blow the extra cash on a header and rather weld up the crack or just leave it alone and wkeep an eye on it. This whole header issue is attaching an extra $300 onto the project. Any thoughts?
