200 is to much for something you're going to use maybe twice.
go to O'Reilly's and fix it for less than 30.

Let me clarify. On the face of the head, the grease will hold much of the shavings. With a small tip, you can vacuum that up. But there will be shavings that will drop in the cylinder. I rigged a piece of tubing to my compressor to reach down to my cylinder head and shot air onto it to force all air / debris upward and out the plug hole. I was watching the pieces come out and continued till I was comfortable I couldn't get any more out. I've read multiple sources that the smaller pieces will burn up / ejected almost instantly to have no damage to any internals.

If you're able to get a vacuum down inside your cylinder head to vacuum it out.... more power to you. You have more attachments then I do. LOL

It comes in a nice case that I can keep with the rig 100% of the time for many years to come. It's proven and cheaper then many alternatives. If I'm out in the middle of nowhere, $200 is nothing compaired to walking 50 miles.

Also, it was my first time dealing with this kind of repair. So from researching on this forum and several local shops who both explained why to go with Timecert over Helicoil, I listened to those who knew more then I did. I'm glad I did.

I'm comfortable with my repair and it's longevity.

Just for my understanding. I thought with the plugs like the NGK they have a nickel plating and that you aren't supposed to use anti-seize on them at all. Please correct me if i'm wrong.

UPDATE: https://www.ngksparkplugs.com/about-...ut-spark-plugs

Yes this is all true. But you tell that to my NGK's that required me to use a half inch rachet with a 4 foot breaker bar that took all my strength the entire time I took the plug out. Entire time they just felt like they were tightening. I also shot them with PB blaster over and over. Tighting and loosening. One plug took me over an hour to remove.

I am super careful when tq'ing spark plugs. I have learned my lesson with aluminum heads a few times.

Use a little anti seize and I have never had that issue before.

Timecert is a permanent fix. Know how many boosted 5.4s are ruining them at high boost to this day? Probably about half. That 30 dollar thread saver, while it may have held this long, is not nearly as strong. On an aluminium head, you only get so many chances. Ill go with the proven product.

Now, in many other places, heli coils are perfectly fine.

The Lisle kit is not a helicoil kit, it uses standard time-sert style inserts. I already owned the kit, so all it cost me was an insert. They sell them in longer lengths, which is what I used. 20K on my daily driver since that day almost exactly one year ago.

I have seen folks not line up the thread chaser correctly and mangle the head. Not fun. But instead of the heli coil, go with the cert here.

I see that you ordered it, have plenty of patience and follow up on how it turns out.

I put the time-sert in tonight. Took like an hour. Drove 10 miles, so far so good.

The time-sert tap was a step tap - the tip was the standard 14 x 1.25 to thread into the old threads (whatever was left) and then the rest of the tap was the larger size. It made lining it up a breeze - just for anyone considering going with a cheaper option.

Also the kit has like 5 extra sleeves. If anyone wants to borrow my set and put a sleeve in, we can work something out so you don't have to blow $200.

He's not a boosted 5.4 though is he..... No repair is as strong as what was cast. To me its just wasting money when you can do the same repair for a third of the price.
also a Toyota mechanic (at a dealership), suggested this product. It's what his dealership uses for this repair.

Well S H I T! My cheap fix bent me over last night. It held strong for about 5k. Blew put last night on my wife's way home from work.
Guess I'll go big this time and order the timesert kit. FML

I'm eating my words now. I jinxed myself I guess. Live and learn

My dad used that O'Reilly kit on his 22RE...lasted for a couple thousand miles and blew out. Of course I had borrowed his truck the day it gave up.

PS I have a set of used 5vzfe heads and I'll set you up with one cheap if it comes to that. For your sake, I sure hope not though.

The reviews on both sets are about the same. I may have not set it good enough. Not sure.
I really hope I don't need a new head.

There are top fuel guys running with time-serts in the plug holes. 50+ psi on nitromethane-don't get much more extreme cylinder pressure than that! Maybe overkill for some, but given the opportunity I'd rather not have to fix it twice or be stranded someplace.
