Been trying to track down an exhaust leak, and found a huge one between the turbo o2 housing and the downpipe. Took off the 2 bolts holding it together to check it out and there's no gasket there lol. My question is what gasket goes there? I've been searching and found out that it's either a "doughnut" gasket or a 3" regular gasket. Which one is it? Or is it both?

 

Item no. 13085 = Mitsu part no. MR450703

 

Where can I find these diagrams? And thanks!

They seem to have a good collection of part diagrams. Might take a little digging to find the right part you're looking for.

 

I believe it's the same dounut gasket that's found on a Honda CRV 2.4L engine when I got it at Advanced Auto Parts.

 

How can i confirm this? It looks similar and is nearly 3x as cheap as the oem mistubishi one.

 

Measure your opening and head down to your local parts store, ask for the CRV donut gasket and measure that opening.

 

Which downpipe are you using? Not all downpipes require a donut gasket.
