I know this topic has top billing around NLOC board, but I would like an expert opinion.
My 1999 Gen 2 is a low mileage unmolested truck that I intend to drive in stock configuation. Being a mechanic by trade I understand that normally if you follow maintenance procedures as written in the tech manuals, use proper tools, and common sense, you should have no problem completing any task successfully.
With this thought, what is your opinion with regards to the plug issue? If completed as per instructions, using a torque wrench, careful not to cross-thread during installation etc...would a person have to worry about a plug departing? Are the earlier heads so fragile that failure is just a matter of time?
Should retorquing plugs at certain intervals be a part of my maintenance program?
Thanks in advance
