870 leaks fluid from exhaust manifold - Redland1 - 11-30-2023 What could be causing the leak? RE: 870 leaks fluid from exhaust manifold - marek4792 - 11-30-2023 Could be valve guide seals, piston rings, scored liner, leaking injector, leaking injector cup? RE: 870 leaks fluid from exhaust manifold - Redland1 - 11-30-2023 Another pic RE: 870 leaks fluid from exhaust manifold - Rawze - 12-01-2023 Looks to me anyways .. mostly like oil from leaky valve guide seal(s) that is sneaking past the manifold gasket. Valve guide seal seepage is not too uncommon on a head that is getting old and wearing out. |
