Broken Spark Plugs

Hello folks; My 07 Nav started to miss today so figured it was time to change the plugs. The coils tested okay. # 4 and #7 spark plugs came out but the lower brass or copper ends with some porcilon stayed in the hole below the threads. Is there a way to remove them or am I pulling the heads. Vehicle has a 5.4 with 122,000 km on it and I've owned it two months. I called the original owner and he said they were original plugs. Story of my life. lol

Re: Broken Spark Plugs

Thanks a million Bert. There has to be one avalible in the Toronto area and I will find it. The long weekend is starting so it's not going to be easy finding it. All the other plugs came out with alot of crunching noise but I think the Fluid Film spray and workng the plug back and forth helped. I have Autolite HT15 Plugs going back in. Should I put anti-sieze on them. Thanks Tony

Re: Broken Spark Plugs

I always put anti-sieze on the ones I do and not on the seating area, On those, I put some around the smooth tip area that gets stuck in the head. None on the tip though.

Re: Broken Spark Plugs

Thanks again Bert. Bought the remover kit for $90.00 and it worked really slick. Got all the plugs done. I put new pads and rotors on the front and now have the right side getting very hot. The old pads were worn and even on both sides. I leaning towards replacing the calipers. The pistons look like plastic mold type and suspect they are sticking. Tony

Re: Broken Spark Plugs

Raise the front and see if the brake is hanging on that side. Sometimes pushing the piston in does cause a caliper problem but very rarely. Switch the pads with the other side to see if it changes.
