Well I have a 05 6.0 4+4 180,000 mile I've always took awesome care of her. Well lets go to one year ago I buy new heads arp studs oil cooler and I hate to say it black oxny head gaskets. She San great for a year the all the sudden no start I replace FICM injector harness and engine harness then all 8 injectors she ran awesome for 600 miles then no start. Well I wasn't purging from degas but found out blew both head gaskets very bad ya thanks oxny HG. Well it got coolent in oil and fried all injectors agin so I take it in this time to a rep. Powerstroke mech. New heads oil cooler the whole deal and OEM gaskets he gets it all together runs good then he shuts it down and almost hydro locked motor #8 cylinder well new remand ford head from ford has a crack or issue he thinks so now it's getting torn done agin. Just my luck what's up with ford heads
