Tried looking, its a metal ring, with an oval hollow profile that sits in a slight groove in the exhaust manifold and and crushes to seal when the turbo it’s fitted Managed to stump Dave when I first met him with “name that part” F###ing #win :grin.gif::grin.gif::grin.gif::grin.gif::grin.gif: ---

This is 18 gauge, I reckon a couple of sizes up would do you, or, machine the flanges flat and use a T3 copper gasket. ![20180901_183648.webp](https://turborenault.co.uk/uploads/default/original/3X/1/a/1a0013809f291a107f11bac7c5476cba470ec53f.webp) Gaskets [T3 COPPER GASKET FOR GT30R T3 T4 GT30 40R K28 | eBay](https://www.ebay.com/itm/T3-COPPER-GASKET-FOR-GT30R-T3-T4-GT30-40R-K28/223498076570?hash=item340986019a:g:R-EAAOxy-HtRYXig&frcectupt=true) [T3 T3/T4 4 Bolt Turbo Inlet Copper Gasket For GTR | eBay](https://www.ebay.com/itm/T3-T3-T4-4-Bolt-Turbo-Inlet-Copper-Gasket-For-GTR/163547282971?epid=14022441394&hash=item26142d7e1b:g:WuMAAMXQhuVRPNcj) ---

Mine didn’t have a gasket at all when I took the turbo off. Should there have been one? ---

> [@r5gordini](#): > > Mine didn’t have a gasket at all when I took the turbo off. Should there have been one? Ive run with and without and not noticed anything really. I then had my surfaces machined flat and fitted the commonly available T3 gasket. Then I changed manifold and have never had a gasket since. It all gets so hot and expands so quick.
