Im just curious has anyone ever thought of putting lock tight on the spark plugs? Wouldnt that hold em in place really good. I know 28 ft lbs dry is what your suppose to do and i torqued mine really well. All is well i was just curious if lock tight would work.

 

You dont need lock tite on the plug threads...I torque 28ft/lbs and haven't had any plugs blow out in over 300k miles... 01 5.4....

 

I know very little about lock tight but would it possibly make it difficult to remove the plugs without taking threads with them? The aluminum heads would make me nervous.

 

Thats a very good point. But yes i know if you tighten em down really well and no anti seise. You wont have any issues. I was just curious about the lock tight thing.

 

Do NOT use thread locker on spark plugs.

 

I would imagine the heat would turn that locktite into a weld.. any attempt to remove them afterward would probably take the threads with it.

 

Yea i was never gonna put lock tight on the spark plugs.

 

I agree. Just don't lol. Who asked this question ? Oh Steven did

 

Lol sorry guys i guess it was a stupid question. Oh well atleast i never tried it.

 

PLEASE DON'T use loctite, and if anyone tries it, they are doing it at thier own risk/stupidity


Proper torque is all you need on these 2 valve motors

 

I wont and i wasnt going to. I was just curious if it would work and i see the problems you would have.

 

Why do the plugs blow out in the first place, my truck has 62,000 miles on it.

 

Not enough threads. I think there are only 4 threads.

 

Not enough threads and low factory torque.

 

Which engine is in your 05? The 4.6 has 8 threads and doesn't have a problem, the 5.4 has the 2 piece plugs that stick and break.
