Fix Or Repair Daily?

I am glad I have an 04 with 9 threads.

I was told not all 04s had the 9 thread heads. I was also told that the only way to get them was after the 4 threads blew out and the dealership replaced them. The internet is full of crap if you ask me! lol Oh well... Mine will be SS and I will never have this problem again!

We had this big debate out west on the threads. It appears that Ford switched to the 9 threads heads in 11/03. So a few 04's have 04 threads, but the majority have 9.

Yeah i had my mechanic heli coil it. turns out the f*ckin shank on the plug was too long and thats why it smashed it out. why it took so long for it to happen i dunno cuz i've had the car a little over a year. so i def hafta get 7 more new plugs just to be safe. cuz my luck ill be down in myrtle and another one will pop out. so go figure. and Kenny "f@%# everyone they can in the ass" Ross wanted $600 to fix it. Thats why you gotta love local mechanics. But yeah, thanks for your input ruthless, i appreciate it man.

turns out the f*ckin shank on the plug was too long

So the threads on the plug look like they were just pushed straight out and the end of the plug is smashed? My threads are rounded on the top two and the last two look like they were pushed out. This means the plug came loose and wore the threads down causing them to weaking enough to give out. The end of my plug doesn't have a mark on it so it was not forced out by the piston.

All of my parts and new tools arrived! The Time-Sert kit (FORD Triton Big-Sert 5553) is sweet and I would never go with a heli coil after seeing these inserts. In my opinion the heads should have these inserts installed at the factory!
I am taking Friday off of work (Because its my birthday!!) and I will have the car back on the road soon. Oh and this plug will never blow out again! BTW I asked the tech about putting them in all the spark plug holes to prevent the one plug from acting colder than the rest. He said not to worry about it because it wouldnt cause a difference and I would be safe only time-serting the holes that become a problem. I also asked about a fully threaded insert and was told that the 4 threads are stainless and are more than 3 times stronger than factory. I then asked about removing an insert if something happened and was told to get a back out tap to unthread the bad insert and just put another one in.
I only mention this because some of the threads that I read on the net have more than a few people talking like they know what they are doing but in truth they have never used/tried this product and are talk out their butts. I spoke with two performance shops that use the time-serts and was told the Lightning guys run these all the time. I was told I was lucky because I didnt have to deal with the dents and even holes the spark plugs leave in the lightning hoods when they blow out.

Sorry about the book!! lol

The car is fixed and running better than ever! I want to get it on a dyno again because it feels alot stronger now. When I pulled the TB to get more room to work on the spark plug hole, I found that the inlet had a leaking seal where it bolts the the eaton. If I ever find out what shop worked on this car before I bought I am going to kick so butt!!

The inlet side of the blower is ported so my guess is the seal leak and the loose spark plug was the cause for the low numbers on the dyno. I can't wait to run it again and see how close I can get to 500rwhp.

Thanks to everyone for the help!!
