Spark plug blew out - helicoil?

[Cree]

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. :noidea:

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.

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.

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.

**** me dude, $200? Jesus christ... Worth it I suppose



What does this mean?

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.

I have seen folks not line up the thread chaser correctly and mangle the head.

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. :sobbing:
Guess I'll go big this time and order the timesert kit. FML :behindsofa:

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.

 

[ajordan1975]

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.

 

[Lefty JD]

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.

 

[ajordan1975]

Well....... the second fix blew out after 2days. Time to replace the head. FML!!

S***! Add me to the list.

A month ago, I bought my first 3rd gen. Its an '01 SR5 4x4 w/ 264k miles. tonight it blew the center plug on the passenger side and destroyed the coil while it was at it. Just this past week, I learned of someone looking to sell an '98 2wd w/300k miles with the same motor as mine for $500. Owner said that it doesn't idle, but would run if you keep the RPMs up a bit. I almost feel like it'd be stupid to pass this up, or am I missing something? Wouldn't the head from that one be a direct swap for mine? Then I should have lots of other spare parts too, right?

Being someone that is new to 4Runners, I would greatly appreciate any advice and guidance.

 

[thegipper]

Unless the seller swapped in a 5VZ-FE, his 88 does not have the same motor as your 01. If you meant to say 98, then it would have the same engine assuming its a V6 and not the 4 banger that was available in 98.

Your other options are to fix your head with a time cert or find a used one on ebay or your local JY.

 

[Adamdmc]

I did mean '98. I guess that I fat fingered the keyboard on that one.

I guess that I'll go ahead and address those leaking valve cover gaskets while I'm going.

From the vast experience out there, is there anything else that I should look at addressing while it's torn down half way?

Go helicoil

...\ blew the center plug on the passenger side and destroyed the coil ...

Exact same thing happened to my '01 about 8 yrs ago. Helicoil has held 100% since. I recommend the helicoil option, cost effective and it works.

Luck and enjoy your Runner. :cowboy:

Put an iridium plug and put JB Weld on the threads... should give ya another 100k

Lol.. only you..lol.. You could at least use the high temp JB weld.

take your time, and dip the tap into grease each time. remove and clean the shavings often. that should prevent most of the chips from getting into the cylinder. the tiny ones that do(if any) get it will either be burned up, or ejected out the exhaust.

I did this on my 22RE about 10 years ago. it was my daily driver up until 3 years ago. its been fine ever since.

Yes. Done many. The above advice on the grease and cleaning is key.
Clean up and use the correct high temp thread locker.

 

[brillo_76]

I was fortunate not to have to do this on any Toyota yet. However, I could see a cross threaded strip threads spark plug hole needing attention to keep the plug in.

I would tap and oversized thread nipple in and thread lock that in there. Then you have good threads for your spark plug to hold.


We did that on my brother in law ford f350 that kept blowing the coils out and taking the plug and cylinder coil with it. Once that nipple went in and was solid we haven't blown one yet.

Haha your idea of retapping a larger hole is way better but shoot, if it was buying a new head or high temp jb weld I'm going with the high temp! Haha especially it being winter
