Blown Plug Cost
Hi Guys.
I hope this is my last thread ever on blown plugs!
So #10 was fixed 6 weeks ago. #9 is now blown. Truck is at the mechanic right now, he'll have a quote for me on the #9 repair later today.
He is also going to give me a price quote on doing all 9 remaining plugs (no idea if any have been done in the past).
My question is, what is a fair price (or hours) to pull the heads and do all the inserts at once and get this delt with once and for all?
If I do them all or not is tough, I have to take into consideration the value of the truck and what I paid, but I think I would be willing to pay up to $1500 for all of them. Cost for #10 was $450ish, I expect cost for #9 will be about the same, but plugs like #1 would be far easier. What does it take to remove the head? Once removed doing them would be a piece o cake, maybe it makes sense.
Ug.

Find a new shop ASAP. There is no reason to pull the heads because a plug blew. Use a timesert and forget about it.
The reason your spitting plugs is because they were never installed properly. Pulling the heads is a waste of money.

I don't have to do that, but would pulling the heads (if you were to do all 9) be significantly cheaper labour wise as putting in the new plugs with the head on the bench would be much faster and easier?
I have not seen the quote yet, so not saying I will even go with doing all of them, but just curious what a reasonable quote would be for doing #'s 1 through 9.

You may want to buy a timesert kit and do the job by yourself, since there may be future blown plugs . Here is a very nicely written "blown spark plug thread repair" procedure with photos . Also visit and read the process at timesert.com.

I timsert is 110.00 per cylender at Ford. Pulling the heads are an easy 1,500.00 job. It's not worth it. The plugs should be changed every 50,000 miles and torqued to spec. I've had over 5 modular ford vehicles and never had one problem. I do it by the book and have had no issues in over 250,000 combined miles.

Lets forget about the method (removing head vs not) of replacing #1 through #9. What would a fair price be to put inserts in all 9?
(I am not comfortable doing this myself - also there are only two places where I live that will do this replacement, one is the mechanic I took the truck to, the other is the dealership). Other shops I have called won't do this repair. Shop I took it to has been around a long time and gets great reviews all over. But this thread is not about if I picked the right mechanic, just what a fair price would be to deal with the insert.

Just got off the phone with Ford, they charge $119 roughly per plug using Helicoil. I have heard this is not the best way to go though... hmm...

When I bought my used truck I pulled all the plugs and installed new ones using the motorcraft double platinum plugs. A little never sieze and correct torque and I don't think I'll ever have one blow out. Never pull heads to do this job. I would would replace all the plugs exactly as the book says to.. No over torque silly mechanic crap.. They have to be done correct...Thats not to say that they wern't done wrong previously..
Timesert is the best way to go....its permanent..

Get the one plug that blew fixed with a Timesert and leave the rest alone. Just check to make sure the other plugs are tight and in good shape. If the plugs have anywhere close to 50k miles on them change them all.
I am not recommending putting Timeserts in all 10 holes however it is the easiest and best to pull the heads to do it. However it is often not economical to pull the heads. When doing the repair on the truck it can be hard to get every single aluminum shaving out and is harder to ensure the hole is reamed to the proper depth. Like I said it is just easier to do Timeserts with the heads on the bench.
You are not dead in the water if you blow a plug. Just unplug the COP and the injector on the dead cylinder.

I had #9 on vacation a couple of years ago.....cost me 280.00 to have it fixed that day. Then...it was still running rough.....and found out they loc-tited.the insert to the plug and never-seized the insert to the plug hole!!
Once home a few days later....took it to a shop(have know the people for years) and asked what they would do. So.....had them pull both heads.....insert every plug hole.....did a valve job....cleaned all injectors.....replaced all exhaust manifold bolts.
Cost me 2400.00 but the job was done and done tight. Took them about 4 days.

When I did all ten of mine it was about 12 hrs. The hardest two are on the back passenger side the front 6 or 7 were very easy to do. So next time would be a little faster but I hope the gives you an idea of how long it took.
