Sealing and Service

Up-pipe flange leaks allow exhaust to escape before it reaches the turbine. Soot near a connection, ticking or puffing noise, and reduced boost response can point to a leak. Inspect the pipes and flanges to locate the source; new gaskets cannot repair a cracked pipe or distorted flange.
