Well...this ain't good

[VeryTangled]

I'ma challenge JM to tell us a '36 is not cooler. I need something to clean my eyeball cuz it keeps falling out!

Keep the 3w's rolling at all costs!

8RT in a ‘36!
I have used my KD spark plug hole insert tools many times. The common 14 mm plug tools also work for putting a plug insert in the oil drain hole on Honda cars.
Any good parts store should have the K D insert kit. Put the insert on the spark plug and screw it into the head AFTER coating the insert with blue loc Tite
I just wasted two days trying to find Keen,Serts, Time Serts or whatever. I am not too crazy about Heli Coil.
I found what I needed at Thread Kits Company
Threadkits.com
310-897-1995 there in Carson, CA
Very easy place to Beal with, they have rivet Serts n other thread stuff too.
The Time Serts for bolts kit has a cutterthat you use after you drill out the old threads.it cuts a groove around the top of the hole. The inserts have a ridge or hat brim around the top of them so when you put the insert on the bolt looking insert driver you can Omnitel secret the insert in until the ridge bottoms out in the groove at the top of the hole leans the insert flush with th top of the hole.
When it stops turning you keep on twisting the driver a couple of turns which expands the bottom of the insert lock it in so it can never back out.
I don’t know if Time Sert’s spark pug holrepai kits have the lock in feature.
For plus I have only use KD, HeliCoil and KeenSert.

And BTW, you guys are the best. There is simply no comparison to the amount of VARIED experience here on the Barn. Motorcycles, BMWs, whatever, and experiences from all over the world over many years and generations. It is really quite remarkable when you think about it.

Makes me think even I can do this.

[RKS.PA]

Heard, you really do have a "Plan B":

Based on the work you and DD did on the T5, this should be a piece of cake for you! And, yes, the knowledge here on the Barn is amazing....and I, too, am thankful to have access!

Are you going to just repair the one that blew out or are you going to do all of the spark plug holes? I would recommend pulling both heads and do all of the holes as in preventative maintenance. I'm too anal to expect that only one is going to fail.

I always use anti-seize when putting spark plugs in aluminum heads but someone mentioned proper torque. What would that be for a spark plug in an aluminum head?

Need to be careful with the torque values if using a lubricant such as anti-seize. Most torque values are dry and it is easy to over torque when using a lubricant! As a kid I torqued spark plugs and it was the only time in my life that I broke a spark plug!!

I've gotta agree! The values I listed above came right off the ol' interweb right where anyone else could have found them. I myself have never used a torque wrench on a plug. "Feeling" plugs in to just the "right snugness" has always worked pretty well for me. That's a coupl'a pretty technical spark plug terms there if you've never heard them used before. DD

I've been twisting them into aluminum heads for longer than I want to admit to. Always used anti-seize but never a torque wrench. Just went "kinda light" on the torque because it was aluminum. Haven't "lost" one yet but I guess there is always a first time.

[Heard]

Ken - I'm going to have to think about that a bit. I'm planning to just fix the one but as I mentioned, these heads seemed a little sketchy when I bought the car.

As DD mentions, I've always just snugged them up just right by hand. Never had a problem. BUT, on these heads, they just don't feel quite right. I've changed the plugs twice I believe. The last time was just a few weeks ago. I did it cold but as I was doing it, I was reminded that some of these holes just ain't quite right if you know what I mean. They probably all need to be done but that is my plan B. Oops.

Cathy usually won't go with me when I go for a drive. She says she has to stay home so she can bring me tools when I break down. Damn it! She was right. 'Course the tools didn't help me this time but she brought them anyway.

[RKS.PA]

Not to be disrespectful of your time and budget, but I'm with Ken above on fixing all 8 of your threads. After you do the current bad one, it's always going to be in the back of your mind it could happen again with one of the others.... out there on the road. Plus, those heads are worth restoring and a very "cool" part of your car!!

My wife is like Cathy. She waits by the phone when I'm out with the '47 and she's had to rescue me on more than one occasion and always relieved when I'm back in the garage.

We all look at our projects in our own way....just my opinion.

[aussie merc]

check the websites of manufacturers of the plugs you choose all you need is generally there

[Heard]

Well, I got the Time-Sert kit but it won't work with the heads mounted. The tap is too long and hits the valve long before all the threads are cut. Plus you are supposed to run it down to where the flutes are 1/4" below the surface, then slip the seat cutter over the tap to clean up the seat. No way is that happening so I pulled the head.

It actually looks pretty good to me. That pink stuff is the no-rosion in the radiator. So I'm looking for ideas on cleaning up these heads. I'm thinking of soda blasting and re-painting them. What do you guys say?

Also, does anyone have any ideas on what the numbers mean and what the extra acorn nuts are all about? Oil filter mount?

Thanks!!
Heard

[tubman]

Sounds to me like you have all of your bases covered.

[mogiley]

what do you run for engine fan

[jimvette59]

Nice set of heads I can't help you with the numbers but the extra acorn nuts are for a oil filter.
