ARPs torqued to 245 not 210...now probs
2004 F250 w/ 80k. All the fixes back in April...oil cooler, egr delete, victor rienz gaskets and studs, fluxed heads, coolant flush, and turbo cleaned.
I have also replaced the remainder 6 of 8 injectors this past month.
Ran awesome for a few months, then noticed some puking recently (before the 6 injs were swapped). Then followed with constant tea kettle whistle under load/higher boost. My mechanic had it for a couple days and found that I'm getting exhaust pressure in my coolant....degas bottle would max out the pressure gauge within a min of driving. We have determined that it has to be one of the gaskets allowing exhaust to mix w a coolant passage.
I found out my mechanic did not torque the ARPs to the new rating. He has never had a truck come back, and is doing all labor for free.
Would this over torque cause my head gaskets to leak after 3 months? Why does the grease used, change the torque? Should I use the VR gaskets again, or should I buy OEM?
