First time replacing spark plugs. Overtighten Spark plug!
Howdy,
Read online spark plugs on my 2001 Dodge Ram 1500 5.2L was suppose to be at 40 ft/lbs. Pulled out my wrench and did just that.
It went a full turn and 1/4th after hand tightening.
I un-screwed it, checked for stripped threads didnt see any.
Whats next? I screwed it back in and did that 1/16th turn. It remained tight(not loose)
What should I do? Kinda desperate. Fimish replacing them all at 1/16th snug ? Turn on and see if it blows out??
Any help would be apperciated as its my only ride.
Whats the torque suppose to be anyway?

You may have had some crude on the threads when you hand tightened it, not allowing it to seat. Also as you crush the sealing washer the plug will turn some. In theory, you should replace the sealing washer every time you remove the plug, but not practical to do. Follow Hey-You's instructions, you should be fine. Some spark plugs had those type instructions on the package. Also hand tight is somewhat subjective, as Hey-You said tighten until they seat, using light tool pressure.

a very small dab of anti-seize (lube) on the plug threads will help give you a better feel of what seated is. just keep it up high enough up on the threads so you don't get it on the end of the plug when installing them.
....you really should use it anyway when changing plugs. you'll do the threads in your heads a favor

I went ahead and hand tighten and used a wrench to 10 lbs/ft. I should be fine? It did well over the turning radius of "Hey you" Statement.
30 ft-lb would be well over the turning radius anyone else is saying. So I will ignore this statement.
I'll keep the thread lube in mind next time(they are already in).
I'll start it up! Any other objections?
Thanks Guys! I look forward to many forums post here!
