idosubaru Posted July 6, 2020 Share Posted July 6, 2020 Our daily driver 2006 Tribeca - Wire brushed the exhaust where the doughnut gasket seals, installed a new Subaru doughnut and it still leaks. What are my options? Quote Link to comment Share on other sites More sharing options...

forester2002s Posted July 6, 2020 Share Posted July 6, 2020 Take the joint apart, reverse the donut, and reassemble. Quote Link to comment Share on other sites More sharing options...
lmdew Posted July 7, 2020 Share Posted July 7, 2020 Lots of times the old donut will leave section in the rear pipe. I've had to chisel them out. 1 Quote Link to comment Share on other sites More sharing options...

Chiseled out and wire brushed both but the rear was harder to see from the angle I was working and most of the chiseling was up front so maybe I missed some Quote Link to comment Share on other sites More sharing options...
lmdew Posted July 8, 2020 Share Posted July 8, 2020 The shoulder of the spring bolt should be up against the flange. The spring hold tension on the connection. 1 Quote Link to comment Share on other sites More sharing options...
