tell the difference > between a clicking lifter and an exhaust leak from a > cracked exhaust manifold? For mine, the exhaust guy had on gloves and ran his hands around the manifolds/pipe mating joints. When he felt airflow, he had found the leak via the pulsing exhaust leaking out. This was while I was in the car holding it at 3k RPM. Leak on mine was at the pipe/manifold joining flange. Not a good technique if the crack is on the underside of the manifold next to the block, but that's not the stressed area, for the most part, and I think the metal's thicker there, anyway. Gloves used were finely knit (cotton, wool?) and may have been specific to welding, but not air-proof rubber or something like that. ===== Kenyon Wills 6o LeBaron - America's Most Carefully Built Car 73 LeBaron - Long Low & Luxurious __________________________________________________ Do You Yahoo!?
