Looks like I have a coolant leak form my EGR valve. If this is the case is there any remedy except for replacing entire valve? I read that it cannot be disassembled, so assuming it is just a rip and replace for 600 over a 5 dollar gasket.
Is it possible for an EGR to leak manifold pressure into the cooling system? I'm not sure how they're designed, trying to rule this out as a possibility of why my cooling system is pressurizing under boost (of course the alternative is a head gasket failure).
It does see the pressure from both the exhaust side and intake side, so maybe before the coolant system pressure builds to operating level. The EGR does include the coolant system circuit in its design.
