I need to replace the factory rubber PCV 'T' elbow/grommet/whatchamacallit on a log TI engine in my brother's GLH Turbo. It has hardened and cracked and is seeping oil making a mess. The OEM part is no longer available. Has anybody ever recreated this piece using something like 1/2" copper sweat fittings? I'm hoping to fix it while still using the stock PCV valve in the stock location.
