- Ford 5.4 Triton is notorious for blown spark plugs. After repairing mine the same spark plug blew out again, this time the insert blew out as well and stripped the threads In cylinder head. The proper repair is to replace the entire cylinder head: But I’m cheap, hardheaded, and pretty handy. This means I temporarily saved $3000.00 until the new spark plug fouls or blows back out the 3rd time. We shall see…
Excursion, F150, F-150, F250, F-250, Expedition.
I made a trip to California. I had one blow out on the way out there, so I was there. I did all 8 of them at the same time. And I've now got probably close to 50 60000 more miles on the engine since I did this. I used the calvan kit. I used only red JB or red. Threadlock, on the kelvan, threads and not on the spark plug did it exactly the way it was shown on the internet and have had no problem. Made sure everything was clean and proper. When I put it together like I said. I did all 8 of them at the same time. Took me 7 and a 1/2 hours. No problem. Like I said, I probably got eighty thousand on it, since I did it
I use JB weld high heat metallic paste, it is on EBay for about $10 bucks. I cover the entire insert thread & collar. My 5.4 2v Expedition has blown 2 plug and I used the Calvan kit. No problamo!
The J-B Weld 37901 ExtremeHeat High Temperature paste comes in a 3 ounce plastic jar and you just use it instead of red thread locker.
I fully recommend JB Weld to anyone installing insert collars in their cylinder heads. I’ve seen collars come out with the spark plugs on engines when they used red thread lock.
I hope things are better. Fords specs under torques them at 13 foot pounds. Ford mechanics recommends 22-25 foot pounds.
You didn't install the insert correctly. Time Cert red locktite on the insert. No way that insert should have come out of it was installed correctly. You probably didn't torque the insert enough. Wayyy to much JB Weld.
On the first application I did put red locktite on the insert and thought I torqued it properly. I assume I did do something wrong. The problem is the threads are gone that are supposed to hold the insert in. The proper fix now is a head removal
What is the news now
It blew out at 10k miles and I JB welded it back in again. Eventually I’ll have to have the head removed and have it repaired correctly but it’s getting me by till then. The problem is the threads are gone that are supposed to hold the insert in, and that’s the biggest insert made.
