I recently got the EGR valve replaced and when everything was put back together I started getting air leaks everywhere, so I replaced a few gaskets and clamps. The only issue I’m having now is the clamp where the EGR tube meets with the cooler, it keeps leaking air, it whistles obnoxiously while I drive. I’ve replaced the gasket, clamp and even the tube itself, it only minimized the leak, the mechanic said the cooler is in good shape and I’ve hit a wall. Any suggestions, ideas? Thanks in advance.
