I have a S366/S480 Twn setup on my truck. I noticed a snall exhaust leak and it seems to be coming from the S366 wastegate plate. I there supposed to be a gasket there or not?:confused:

High temp silicone, but it burns off.. Mine got hot and warped so I bought 2 plates and used a slightly longer bolt and some high temp red silicone.. There is a company that makes a thicker plate but I could not get ahold of them when I needed it..

I had a similar issue with our BW turbo our Cummins. I ended up finally breaking down, drafting up the file, and cutting one out of 1/2" stainless (13 SS housing) on out CNC plasma table. One a regular cast housing I would recommend sticking with mild steel. No issues since the upgrade.

Guess I'll need to keep an eye on mine.

No all the newer ones are said to have the thicker plate. Send me a pic not sure if that part showed up in the others. I was told yours had it when we ordered it if not we will get it. Since we had plans for a add on down the road.
