hey guys wanted to know i heard that 5.4 engines have a problem with the #4 cylinder plug blowing out dew to the fact that there are only a few threads in the head. i also heard that you can get a insert to go in to add more threads??? what do you all think??

 

Have not seen that problem in the thread(s). There is a problem on the 5.4 L 3-v with plugs failing when removal is attempted.

 

Do a search on "plug blow out". Should find much info.

 

search it or go back a few pages i just changed mine and it turned out fine on my 5.4 from 2000... i was scared poopless but all went fine and still is so dont worry about it

 

The blowout doesn't necassarily occur immediately thereafter. In my case, its was over 6 months after I changed the plugs. And then when it did go, I just popped a new one in and it lasted over a year before it went again. There is no method to the madness..........

My number 2 blew out...Luckily I was at a garage when it happened and the plug that blew screwed right back in there...Drove it for several thousand more miles before doing a tune up!! They all came out just fine. But yes, they don't have many threads on them.

 

Does anyone have any hints to ease plug changing on the 5.4 engine? I found it a real chore, especially the left bank rear two plugs. Any suggestions would be really appreciated.

 

I pull the front tires and lower the front end down so I reach the back comfortably.

Hope that helps - it's not that bad.

 

My number 5 plug blew out a few months ago, Look back threw my threads on this website. The truck is now back to 100 percent now.

 

sorry that should have been the number 4 plug.

 

I climb up on the header panel, have a seat and go to work
