Earlier today I was replacing my old plugs with a new set of Denso's. I removed the old plugs with no problem. I installed the new ones and hand tightened them all down. Then my neighbor came over with his torque, and we set it to the correst ft. pounds. He went down to tighten the number 1 plug and it popped. So now it just turns and turns. It will not tighten nor will it losen. The plug will move a couple of millimeters up and down, and slightly rock back and forth. Does anyone have any advice on what i should do. PLEASE HELP...................

 

what torque setting did you put the plug to? how many foot pounds (Newton meters)??

 

I'd say bring out the tap and die kit.....but I dont know how safe that would be to mess with something like that. It sounds like you cross-threaded it on accident from the beginning. Is there any noticeable damage to the threading on the plugs?

 

lolz, i've cross threaded many things, so now i always put it in and out a couple of times before tightening it all the way by hand. but yea getting it to tight witht the socket will break the plug.

 

i always just put in my spark plugs hand tight and that always seems to be enough, and a good way to get them started right is to use a rubber hose the slips over the plug and lower it down and get it started that way then tighten it with a socket.

 

That is exactly what I just did, they make this rubber spark plug grabber that you put in a socket, and it hold onto the spark plug so you can put it in and take it out with ease. The only problem is that the rubber grabber stays on the spark plug so you need like a long needle nose pliers to get it out!

 

General rule of thumb........plugs with gaskets, 1/4 turn after hand tight. Plugs with out gaskets, 1/8 (or less) turn after hand tight.

We had set the torque wrench to about 25 newton meters. And i dont think i cross threaded it cause, i had hand tightened all the plugs first. And when i was hand tightening them they all went in very smooth. The problem happened when my neighbor went to go and tighten the first plug with the torque wrench. I think he might have snapped the plug just above the threads. If he did would it be safe to try and pull the remaining part of the plug out, without anything falling into the cylinder?

 

Okay so can you pull anything out of the cylinder? [/align][/align]If not, then I would safely/gently try to loosen it and pull it out. If its hand threaded, nothing can "fall" into the cylinder. [/align]

 

well i tried and tried to pull it out. it will turn in both directions and wiggle back and forth, but it will not pull out. i am stuck. my neighbor is willing to pay to get it out, but his machanic told him that the head would have to be pulled, and the job would take about 8 hours and cost between 800 and 1000 bucks. what do u think?
