So when i bought the car the previous owner installed a 5 layer metal head gasket. It has been running great for like 5 years on 14psi and has seen 18psi but recently i was pushing 19 psi with a peak timing of 22 on e85 and i starting pushing coolant and my temp would go up really fast. I'm not burning coolant or oil and they are not mixing. I freaked out when i got on it and my heater went cold. I did a compression check and its good and i pressurized the coolant system and it held pressure. I replaced the radiator cap. If i lifted the head could my 6 bolt geadstuds stretched and if the head lifted is the head gasket no good? It driving fine right now and im wondering if i should put in the arp's and see if it stops or should i just replace the headgasket with a felpro composite i have?
