V10 Plug Blow out - Diesel Forum

Drunknmonk · 03-09-2006, 09:26 PM

Ive searched on the site about this but didnt see anything. Wed i was driving and blew my #5 Cylinder Sparkplug out of the head. Got it fixed with a helix but was wondering if anyone had heard of Ford doing anything about this? Everything I find on the net is that nothing has been done so just curious. Thanks

From everything I've read (mostly stuff on-line, so take it with a grain of salt...), Ford doesn't recognize this as an issue PUBLICLY. If it isn't a design issue, why did they change the head design to include more plug threads? Anyway, at this point you know about the helix fix. If you find anything that would help the rest of us, please post it.

Yep, fixed if in warranty, otherwise not, they replace the head with new.

Who/where did you get yours fixed if we may ask?

I was just about to do the o-rings on my 7.3 when I was interrupted by this very problem on our '99 Expedition. I checked out a site called consumer affairs (not to be confused with consumer reports) only to find literally hundreds of reported cases just like mine (not to mention the ones that don't get reported). Most of these happened after the warranty expired which left people paying anywhere from $2,000 to 6,500 for one poor guy's V-10 repair. I my self am still in the process of trying to find out if our Expy is covered under the extended warranty. I have found a company who offers a heli coil type insert which is made just for this problem. I think it was called the Triton Quiksert by Time Sert. I've heard that the inserts are actually stronger than replacing the head with another defective unit. The kit costs 450.00 but if the warranty doesn't cover the repair, this is the way I'm going. I'll try to get back and let you know how it turns out. Good luck, Chris

I used to work for u-haul. This was a HUGE problem we ran into. I can not even begin to count how many times I replaced heads due to spark plugs being blown out. I have probably replaces 100+ sets of v-10 heads due to not having the correct torque on the spark plugs. Being a bigger company we didn't ever heli-coil them. Although I have seen heads that have been repaired roadside and they only hold for a very short time. I am not saying this to make anybody worry, but I could deffinitly make sure you use anit-seize and make sure they are tight in order to prolong life. Scott
