On th elake yesterday, my engine bogged down and would not go over 5K rpm's. I looked at the engine and there was water leaking out of the bottom of the joint where the tuned pipe bolts onto the exhaust manifold (787 engine) I recently replaced this gasket when I had to have a plug welded on the tuned pipe. When I took off the pipe the bottom part of the gasket was bent down slightly opening the gap where the water flows through the tuned pipe. My question is, when i installed the pipe onto the manifold is it possible to warp the gasket and cause it to leak? Or do I need to apply sealant when bolting these pieces together? When I disassembled it the first time to fix the tuned pipe plug, someone had applied sealant.
