I found a great source for the 20mm expansion plugs that we 1st geners like to use for blocking the coolant passages in the rotor housings. The same ones that are available through pineapple racing for 7 bucks a p[air can be had at the site below for 8 bucks for a pack of 25!!! Just thought I'd pass on the info!

you can say that again . awesome link....they have everything....thanks for sharing.

 

no problem!

 

Sweet link. Thanks!

Now just sell a couple (@ $2) and get your $8 back!

 

Excellent. Might have to invest in a pack of those.

 

That's about the same price I paid for a box of Dorman 20 mm freeze plugs at the local parts store. Good find.

 

They're not brass. Does it matter?

 

they are the same ones pineapple racing sells.

 

he already said that.


good find. so now u know how pineapple racing, and other places, make money off of them.

 

I don't think it should matter Jeff.

 

Hey Ken,

I could use a couple of those....are selling any? I'll help reduce your initial investment costs.....

Pat

 

Sure Pat, I can send you a couple, just pay shipping. Say 5 bucks?

 

ill buy some too at 5 buck including shipping! haha

 

I've never seen brass freeze plugs. Only ones I've ever seen/used are the galvanized soft steel ones.

 

Man, $5 shipped for a pair of those may seem like a decent deal, but a couple years ago there was a member who was having trouble finding them. I went to my local store and bought some @ $0.49 each, and dropped them in an envelope with his address on it. Total cost, under $1.50. I just told him to forget about the money, since he had previously answered a question for me and it saved me at least 2 hours of searching. Figured that was the best way to say thanks......

Edit: Wait, it was a bit more than $1.50. I sent him 4 total. Still......

 

The ones Mazdatrix sells are brass. But it shouldn't matter either way.

 

I've only used brass. I wonder how well steel would work.

 

I got the Dorman ones from rockauto for a few bucks when I was ordering some
other things. They are steel and work like a champ. I did use the high temp silicone
as a lubricant and sealer when I put them in. I almost pushed them to far in, so
be careful not do that! Put them in last year and so far no issues.

 

Rogue... I am in no way a shipping expert I just figured in a flat rate envelope they should be around $4 or so to ship and $5 is just a nice round number. Sorry if I offended you, I'm the last guy that would try to rip somebody off for a buck.

 

didn't know any were made from brass, steel plugs is all i've ever seen used. in cooling systems that r poorly maintained, if at all, the steel plugs would rust away from the inside and eventually spring leaks. maybe that's why the brass ones came about.

 

No offense taken. I have no clue what type of mailer you were planning to use, nor what the crooks at the post office would charge to send it.
It's been a while since I sent those. I'm not even sure where the others I bought at the time are right now.
5 years ago, I put the steel dorman plugs in my engine. So far, no signs of any issues. Of course, even if they were to start leaking, I used the orings as a secondary means of sealing......

 

I clean up the housing mating surface with a sanding roll, then use J-B Weld to seal/lock the plugs in place. Use a socket that just fits inside the plug's cup, along with a 3/8" extension and tap the plugs into place. It is easy to tap them in too far and have them drop into the coolant passage way. Tap until they sit 1/16" below the housing surface then seal the joint with more J-B Weld.

 

Maybe my housings are oddballs, but they had a ridge inside them. I just seated the plugs against the ridge. I remember thinking "these will be hell to get back out".........

 

Check your paypal.
Thanks

 

Will do.... I'm still waiting for them to get to me, so I'll drop a couple in the mail for you as soon as I get them. Should be sometime this week.
