Headgasket weeping oil in coolant - How to fix High boost issues likes this
It's been several years since I posted here, my built boosted GSR is at it again. Leakdown test passed across all 4 cylinders, no bubbles, good pressure, ARP bolts were tightened to spec just last year to ensure nothing vibrated loose. I'm seeing small blotches of oil on the radiator cap again and in the coolant when bleeding the system. I can also tell it is slowly starting to drink the coolant in the overflow, but no overheating what so ever. Last time this happened, tore the head off, decked the head, new gasket and this problem went away. The gasket (bored Golden eagle which is OEM) showed no signs of deterioration and indication it had failed. The car is meticulously maintained, I spoke to GE and ARP last time and they both said they were unsure what could be causing this weeping but it happens. Fast forward now, same issue again. Will likely have to do this all over again with new parts. Such a pain to take everything apart.
For those of you running 20+psi of boost, how often do you refresh the head gasket, I'm aware you can reuse the bolts once depending on stretch, any tips or tricks to extend the life of the head gasket to prevent oil weeping? This is getting old real fast at my age.
