It still works after about a month *by D***N on April 28, 2022* I bought my kit for a 1999 Ford Expedition 5.4L. I like that it was simple to use. After watching some YouTube videos on it I decided on this one because of the price and speed of receiving it. I was going to get the more expensive kit but I'm very satisfied with this Dorman kit. The plug that blew had prior sleeve (slimmer and cheaper looking) from another manufacturer.I ended up getting second kit but from O'Reilly's or AutoZone because I needed it right away on a different day, because I blew another plug. The one I got from the store was 60 bucks tho so almost double what it cost on Amazon.Definitely recommend keeping a kit in your truck for emergencies.Also a quick tips1) I recommend using JB weld 8265s because of the high temp rating and I feel it'll bond better than the loctite. The JB weld has a tensile strength of 5020 PSI and can withstand temps up to 550Β° F.2) use a slim socket to make sure it fits in the sparkplug hole. I lubbed up the exterior of the socket so it wouldn't get stuck and put a little bit of electrical tape inside where the extension mates up with it to guarantee that it doesn't stay behind after tightening the sleeve.3) make sure you watch more than just one YouTube video even if it's not for this sleeve kit because you'll find tips and learn how it works and how others won't work.4) I recommend waiting at least 4 to 6 hours until the JB weld has time to cure a little. I made the mistake of running the engine too early and it had some blow-by. The sleeve held for the 8 miles I drove it but the JB weld burned off. So I guess if it's an emergency and you don't have JB weld or loctite it can get you a few miles down to get some or help.I had to pull the sleeve back out, wire brush it and re-apply JB weld. it held after letting it sit for about 6 hours.A video said that you can get back on the road in 30 minutes using high temp loctite. I just felt like JB weld was a better idea. I'm no mechanic just a do it yourselfer. ### ⭐⭐⭐⭐⭐ Works like a charm *by R***Z on January 30, 2025* 99 Ford Expedition 5.4Been having one on for three years and hasn’t blown out. Installing another one on a different cylinder now. Used loctite on adapter and let it sit over night. Been working like a charm ### ⭐⭐⭐⭐ Worth a try *by C***Y on March 23, 2019* 2001 Ford 5.4 Triton... 4 stars because in theory this is the easiest fix for a blown out plug and avoids drilling the head. The spark plug/boot design is neat too. But I had a few problems with installation.A few reviews mentioned socket selection but I underestimated how critical this is. On my first attempt I ended up with a socket stuck to the adapter in the spark plug well which took hours to remove. YMMV, but most of my 17mm sockets fit into the spark plug well fine but were too snug on the adapter. Most 11/16 sockets fit the adapter nicely but were too large to fit into the well. I ended up using an old socket that was loose enough on the adapter and then spun it against a bench grinder to get the outside diamter small enough for the well. I put a small magnet inside to hold the adapter in place while threading in initially. Use a short socket so downward force can be applied while threading in.I didn't get the adapter set deep enough on the first try and had some ticking during warm up. But I also didn't wait long enough for the thread sealant to cure (used permatex high temp thread sealant rather than actual thread locker) which was probably part of the problem too.I was able to back the adapter out and reuse it. On the second try I applied more sealant, cranked it down a bit deeper (as hard as I could with a medium length ratchet) and let it cure 3 days before starting. Seems to have sealed up well this time, I'll report back if there are any problems in the future. ## Frequently Bought Together - Dorman 42025 Cylinder Head Repair Kit Compatible with Select Ford / Lincoln Models - ENA Ignition Coil Pack Compatible with Ford Mercury F150 F250 E150 E350 Super Duty Lincoln Navigator Town Car Crown Victoria Expedition Grand Marquis 4.6L 5.4L 6.8L V8 Replacement for DG508 FD503 --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/1392631-dorman-42025-cylinder-head-repair-kit-compatible-with-select-ford](https://www.desertcart.tn/products/1392631-dorman-42025-cylinder-head-repair-kit-compatible-with-select-ford) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-06-04*
