Max Capacity Posted February 17, 2020 Share Posted February 17, 2020 http://people.csail.mit.edu/ilh/vacation/ The service manual may help. Not sure how you could cross those lines. 305,600miles 5/2012 ej257 short block, 8/2011 installed VF52 turbo, @20.8psi, 280whp, 300ftlbs. (SOLD). CHECK your oil, these cars use it.

DaveWaters Posted February 17, 2020 Share Posted February 17, 2020 Do you mean that you did a hydrocarbon test and found fuel in the coolant? Link to comment Share on other sites More sharing options...
Max Capacity Posted February 17, 2020 Share Posted February 17, 2020 If that's the case, you have a head gasket leak. That's not very common in a GT. 305,600miles 5/2012 ej257 short block, 8/2011 installed VF52 turbo, @20.8psi, 280whp, 300ftlbs. (SOLD). CHECK your oil, these cars use it.

Nonamedude Posted February 19, 2020 Share Posted February 19, 2020 Well not common unless his new turbo is producing more boost right? Thought that was the point of arp head studs, for boost much above 16psi. No idea how you'd cross those lines. I mean you'd have to try really really hard. They don't have any of the same connections. I could see a small fuel leak if your injectors aren't seated correctly or things like that but they shouldn't mix.

awfulwaffle Posted February 19, 2020 Share Posted February 19, 2020 (edited) < This guy popped a headgasket on an LGT at 17 psi on stock bolts, it is possible but definitely uncommon at near-stock boost levels as Max said. Agreed that it's nearly impossible to cross fuel and coolant lines. Any conceivable way for that to happen would involve you not getting fuel to the injectors, because there's only one inlet/outlet to the oem fuel system. Meaning, your car wouldn't run. Only other thing I can think of is accidentally hooking up one of the throttle body coolant lines to an evap line, but that would a) require you to lengthen the throttle body coolant line and b) result in your pumping the contents of your radiator into the fuel tank. Meaning, your car wouldn't run (for very long). Please clarify, OP. Edited February 19, 2020 by awfulwaffle Link to comment Share on other sites More sharing options...
BoozeRS05 Posted February 19, 2020 Share Posted February 19, 2020 Just sounds like a headgasket to me. Change oil and coolant, and see if it comes back?
