Our Stainless steel M10 x 1.25 banjo bolt has a built in check valve that is spring loaded & will open with only a couple of psi of oil pressure but stays closed when the engine isn't running so oil won't capillary into the turbo when the engine is off, it also incorporates a 1.5mm oil supply restrictor, This stops the turbo from smoking on startup & works especially well when the turbo is mounted below the oil level of the engine.
The main oil galley adaptor suits any model that uses a M16 x 1.5 main oil galley plug in the engine case, it's made from billet aluminium, is anodized black & comes with an aluminium crush washer.
Designed to work with a 10mm banjo & AN-3 or AN-4 oil feed line.
Sold as a set or just the check valve with copper washers.
full set includes :
1 Oil galley adaptor, 1 Aluminium crush washer
1 Assembled Stainless Check valve banjo bolt with 2 copper crush washers
