Let's be honest, I'm sure anyone can do this work with a good driver. However, this is another one of those jobs you can have your local machine shop do when they prep your engine block for assembly.
I think the biggest take away with this video is the nomenclature. I've always called these 'freeze plugs'. It appears that's incorrect and we should start calling them 'core plugs'. I'm OK with that.
Yes, I did go with brass core plugs. Steel plugs are cheaper, but they tend to rust. They both seal the same if properly installed. The brass just looks better and doesn't corrode like steel. It's up to you what you use.
Thanks again to Justin Frische for his help in this video.

This guy needs his own TH-cam channel. I'd love to watch machine shop stuff.
This kid is cool, has sense of humor, unlike a lot of machinists
it just grates my spine everytime someone calls them freeze plugs, yet youtube is filled with videos calling them that. there are so many nooks and crannys in the water jackets that you could easily crack a block from water freezing and those plugs not come out
Kevin & Justin know what their doing. Super cool guys!
I only wanted to see a cam plug properly installed and you delivered! Thank you.
I agree with you. The LS is a good platform, but everyone is doing it. I glad you are going with the 302.
excellent video good techniques what a perfectionist and you are both major gear-heads so you know nothing's going wrong thanks for the great video
Thank you for using correct terminology, and yes, they are actually called Welch or core plugs, especially when my o.c.d kicks in. 😓😒😫🙌
How does Justin install the front cam bearing on a 350 SBC? With the two holes at 10 and 2 ish or with one hole at noon and other hole somewhere else
We need more of Justin!!
Best video yet, a bit of a glimpse into the mind of Eric the car guy, lol!
Cool! I've always known them as Core Plugs but didn't know what their purpose was until today. :)
The reason the plugs are called Freeze plugs is they are named after the engineer that invented the plugs as a way to plug the hole after the sand is removed from the casting. His name was Freeze. I was told this by an engineer from the Ford Assemble Plant in Hapeville, GA.
Great Video Eric...i have always heard them called them freeze plugs too
hi. are you able to post tutorial on datsun late A12 engines (tune up, ignition timing etc....)
@EricTheCarGuy Is there any chance of punching the plug into the motor? Or is there something to stop it at a certain point?
You went all "Harry Potter"... Chamfer Wand??? (shaking my head slowly) Cool vid! I always learn something from your vids. I grew up calling these "Freeze Plugs". I had no idea they were for pouring the sand out, from the core mold!
Justin is pretty natural on camera. Funny dude too.
Do kalvinator engines make performance modifications to V4 engines?
What if in the removal process one scratch a little the seat of the core plug ??
hi fantastic video whats that gasket stuff you are using around the core plugs
I had learned from my dad and uncle to apply gasket shellac to the inside face of the plug to keep it from corroding even if there's only AF in it.
great job. Justin is a funny guy. You too Eric
When I was 17 years old, I didnt know I need core plug sealer. Pissed coolant everywhere!! Motor out again! Doh! Ouch!
Martin Van Luyn ouch
Martin Van Luyn my uncle blew the engine on his Monte SS when the core plug popped out
+Snoopy - oops!
Seems to me that putting it on the block and then driving that tight plug in would just scrape it all off and push it into the block. I get them started, spread some on the outside of the plug, then finish driving them in (also putting a thin layer on the opening like he did). Haven't had one fail yet, but if they fit tight and the surfaces are good, they probably wouldn't leak even without using anything. Anyway, love this project. I have 5 older foxes!
In the process of doing a complete 1000+ rwhp build on my Cobra. FINALLY after 3 years the block is stripped, hot tanked and *most* parts purchased.
Loved the dig at tOSU fans
Driving a 93' s10 2.8 L 6 cylinder 5 speed. Noticed my truck leaking cooant from the rear of the motor Once the motor begins to warm up it leaks all the coolant out but I cant find an exact location
I really want to say thank you for making these videos cuz honestly and this takes courage to do what you're doing everyone knows that those mechanics are really annoyed with you and everything you're saying because a lot of the stuff you're saying is wrong but with that being said or also getting out a bunch of great information so thank you for having the courage to do this
Finally a video calling core plugs by their proper name.
#ericthecarguys I'm shopping around for a core plug kit a wanted to ask what kit did you use, did the shop just provide it
may 18th, man where did summer go? plus I hate seeing steel plugs because many cars I see rust and then leak.
I've noticed that everyone who watches these videos and comment that "you are doing it wrong" are all EXPERTS!! I'm an expert on aircraft engines I R an Airframe/Powerplant Mechanic with Inspection Authorization endorsement... Lol in all actuality I do have my A&P IA but by far am I an expert. I learn after every annual I do or after every cylinder I change out or trimming a Pratt & Whitney PT-6 I'm always learning
They seem to call them welch plugs in Australia.
im glad eric is sticking with ford engine for ford vehicle. i think its hilarious when jdm peeps go jdm for life then have an ls1 in their stanced nissan. lol
So did the one you installed leak?
I had a exhaust cut out on my lifted jeep... had a key fab remote for it. I would sit there and turn it on and off in amazement
any sealer would likely work fine. I use a product called Leak Lock found in hvac supply store. I have used it on everything for my motor builds. let me recommend you try it it is far superior to anything ive found. also, I bought a truck that was neglected, well zero maintenance. after flushing the cooling system one of the core plugs started leaking due to rust. it was a B to change it. a week later, another one, you get the picture. I always use brass now! not saying brass won't corrode, but when you're under the truck with coolant running down your armpit, trying to hammer a metal cup into your block, there's lots of time to cuss and swear to never use the cheap metal plugs. and yes I had to pull the transmission to get those two back there!
I gotta say I think that engine looks sexy in just it's bare steel form. It's probably because I'm too young to have owned a car with an engine that was painted from the factory.
we were taught many many moons ago they are core plugs and the only guy to call them freeze plugs got a rubber mallet scud (bounce) off his head, yes we were tougher back then and teaching methods were more direct.
I used Permatex Right Stuff when it first come out. That stuff is great...
+ Eric the Car Guy my 79 mc got caught in the flood engine is fine thank god but my transmission is slipping who runs good after 25 but before that it takes a while to get up I'm I change the transmission fluid in the transmission fluid filter it was pink milkshake after I changed it a couple of days later still pink what can I do to save my transmission please help
going to try to flush it tomorrow
Can I use cataclean on a 2008 BMW X5 4.8i ?
Something I've always wondered but can't find anything on is how the coolant channels are ran through the block. Are they just straight lines going through the block, or are they snaked through the block?
It's a cavity between the cylinders and the outside of the block.
I bet Justin drives something awesome.
I was googling for welch plug r&r but nothing came up. Then I recalled the popular name for this in the U.S. --- freeze plug. Googling again for freeze plug and I'm here. Lol.
YOURE DOING IT RIGHT!
Welch plugs in Australia?
Cause they never pay off on their debt?
The Welch plug is dome-shaped and inserted into the casting hole with the convex side facing outwards. When installed by striking the Welch plug with a hammer, the dome collapses slightly, expanding it laterally to seal the hole.
Looking forward to the Frische's starting a TH-cam channel. ;-)
You recorded this May 18th? Damn, the car is probably finished at this point!
So there are threaded core plugs. Always though there were just push in types.
I hope Kelvinator charged you extra for how much you've slowed them down with all the filming & chatting. LOL!
i think you meant billed him hourly
Why is the cam plug steel and all the others brass? Is it because it is larger?
Cam plug isn't going to rust inside because there is oil on the other side so it is unnecessary to have brass since the brass is there because it doesn't rust. The oil in the cam plug is gonna keep it from rusting.
Why aren't actual Welch plugs used any more? I'm guessing that this style costs less, but is there any other reason - propensity for leaking, difficulty in installing correctly, etc.?
Should I use steel, or brass plugs? My truck has been leaking antifreeze and I'm going to replace them all, hopefully soon. Can I just use an old 1/2 inch socket with a hammer to push them in place? Also, will the gray rtv from Permatex be ok to seal them. Or should I just stick with the black rtv?
Rtv. Any color. Or use anirobic gasket maker.
Eric, on some other shows I've seen engine builders use an air tool to remove all the sharp edges from inside and around the block. The explanation they give is that it adds strength to the block. I bet it also saves some cuts to the hand. I was thinking about that as I watched the builder turn the block by hand, thought I would ask.
Oh, and "why don't you drop an LS in it?".
In Samuel L. Jackson's voice, "Say LS again mother F&^*$er". The block is plenty strong. Not worried about it. th-cam.com/video/4DGLH_9Tg48/w-d-xo.html
EricTheCarGuy Understood!
Are they the same as "welsh plugs"?
Yes.
Theybare also called welsh plugs. I think the got their nickname freeze plugs because people use the trick of freezing the plugs first (before install to make them smaller and therfore easier to install)
Welch plugs are a little different - originally designed in the 1900s by the Welch brothers at the Welch Motor Car Company of Pontiac, Michigan. They're domed on the outside and you crush the dome slightly after inserting to make it grip the block. Same concept and function, though. :-)
Can you when the engine is all put together tell the veiwers how to properly break in a new engine as in how long to let it run when you first start it and rpm range. I don't know either so it would be nice to know
Already on it. th-cam.com/video/tBD-rFP7q9c/w-d-xo.html
cool thank you
This video was shot in May 2016? ...so is the car done by now? Just curious.
Not yet. Still some work to do.
Hey Eric; I'm not cool, are you gunna run me for pink slips ?. The motor is sure coming together well. I'm having a ball watching this build. It's like keeping up with the Kardashians', LOL.
There is another TH-camr says to put the freeze/core plugs in dry. So which one is it?
Sealer, always.
Thankyou for making the point about them NOT being "freeze" plugs... but waiting for the first comment about how you shouldn't use brass plugs because of different thermal expansion rates compared to the block, which will lead to leaking within five minutes... (FWIW I put brass plugs into my Jeep 4.0L engine five years ago, and they're still watertight, so I call BS on that).
Brass is used - then the are welch plugs. They are dome shaped - you crush them into the cavity.
I'm pretty sure brass expands faster than cast iron, so the plugs should actually seal tighter as the engine warms up. Also, brass was originally used to reduce corrosion so they are less likely to seep around the edges.
aussiebloke609 I have had several freeze plugs rust and fall out on the road.
thisisntme Brass can't rust - only ferrous materials can rust. This would mean that your "freeze" plugs (core plugs) were most likely made of steel instead - quite common these days. However, if using brass, the cast iron block around the brass plug can still rust away, causing the plug to loosen. Also, I'm not sure about galvanic reaction between the two metals, but that could conceivably have an effect also. That said, the original reason for using brass was to avoid the actual plug being able to rust through, since it is much thinner than the surrounding block material. Remember that the Welch plug was invented around the early 1900s, and they probably didn't use good anti-corrosives in the coolant back then. Or antifreeze. Or anything much other than water, really. So anything to let the plug last longer would have been considered a bonus at the time. :-)
aussiebloke609 duh.
How would it freeze?
Lol I was thinking Eric was drunk in the video for a second xD. Love the video dude. Thanks for more Fairmont vids.
I used to know a guy who could install core plugs without any sealant. As i gathered, it involved a lot of fiddling with the actual holes and a tool that looks like a inside taper bearing puller.
One day i'll pull the engine off my Merc and see how he did it, it's been 6 years now since the rebuild, and there's not even a hint of a leak.
Also, he has a cool voice.
Thumbs up just for being a Ford man. How the LS's go in the engine master comp? Oh yeah that's right the Ford Clevors or Boss win mostly.
Recorded at my birthday :D
Oddly enough ive allways called them "Welch plugs" , so im wrong-er and daft-er than you could ever be eric lol :-D
I do like the banter between you both :-D
Welch plugs do the same job, but are of a slightly different design - they are domed on the outside and you set them in tight by striking the dome to crush it outwards against the block.
Ahh i see, ill have to find the person that told me core plugs were welch plugs and give them a good kick up the jacksie LOL :-D.
The ones i see in engine blocks are very different.
zx8401ztv Don't kick him too hard - after all, Welch plugs are just a particular style of core plug, and do exactly the same job. But next time you look at an old engine, check the shape of the plug - the modern style is concave, the old-style Welch plug is convex on the outside - and often has a little dimple or flat spot in the middle where it was struck during fitting. I've seen them mostly on older English engines...Mini, Jaguar, etc. (and by older, I mean '70s and before), so they may be harder to find these days. :-)
You know, i think i have seen a welch plug without knowing it, i cleaned a carburettor from a lawn mower and there was a couple of metal disks in holes, i did wonder how they were held in.
Bloody hell, i must be thicker than a bankers wallet lol :-D
Never thought about those before, but in hindsight, I'm guessing they work the same way. I think the curve and the divot in the centre is probably the giveaway, since that's required to make the rim spread and give you a tight fit. Looks like that banker's wallet has room for two. :-P
so, what I learned from this video. Electric cut outs take forever to open, did not know that. also learned it's been 5 MONTHS since the motor was built and the car isn't done yet, I know things take time and all but can we expect to see the car driving before the end of the year?
Not this year. Remember I also redid the suspension and need to test fit everything. I also need to wire the car.
May 18th eh? Man that's a bit of a backlog of videos to work through.
Loebane that's what I was trying to figure out like where have we been and how have you hid it so long
Not so much a backlog as I have a LOT of videos on this project.
Looks like we have a lot of content to look forward to then!
i'm really enjoying the indepthness of the engine build.
if you look in one of the video you see the engine installed in the background
There Can Only Be One!
we call them frost plugs in Canada, and we remove them to install block heaters.
We also call them expansion plugs. Says it right on the kit package.
i have a 1968 Ford 429 block with threaded core plugs
Those little things can withstand the pressure in the engine??
Jude Infantini those are machined into the coolant or water jacket. So the pressure of the cooling system would only be about 15-17 psi. Nothing that plug cant handle:
Only about 15psi in the cooling system.
EricTheCarGuy can't some systems exceed that?
This was may 18th?
Question is ... Did it fall out?
i thought brass freeze plug i mean core plugs they get soft an pop out cause i wanted to install them in my chey trk
that tool that he was using to put those plugs in should be ground around the mushroom part it's an accident waiting to happen seen it first-hand
Gary Clemons I was looking to see if anybody else mentioned this, that tool is in need of grinding badly I've seen a guy take an eye out with a chunk of a chisel that looked like that
They had so much slack pushing out lol I cant believe they didnt clean after seeing how much was sticking out the first plug... Immortal Motor!
yeah, even for the people that don't care about safety, one of those chunks landing in the motor unnoticed would ruin your day
I know a guy who chipped a tooth that way lol.
@ paul smith.. very true, i'd never even thought of that
The cop car wheels would make me question your 'Sleeper' status if I didn't already know what was under the hood.
Ok I'm just a shade tree mechanic, but why don't you use a electric press on those "Core Plugs" Seem like as many as you do it would be worth the money? I bet many other things need pressing on and off... Just a thought.
immortal...last time somebody told me that one? It wasn't pretty to be sure...engine parts everywhere. LOL
Eric can kill the immortal engine.
Over Rev is the quick and painless death
No oil changes is the slow and painful death
IIGrayfoxII someome should start Ericthecarguyfacts site.
You should set it up so that the exhaust cutout automatically opens when you floor it.
7:22 "Do people still dance?"
Core plugs!
i know them as welsh plugs in australia
Same, When I got a carb rebuilt kit for the line trimmer the list of parts listed them as welsh plugs
have only known them as welch plugs here, never heard them as core plugs in aus
Same here in south africa.
maybe a guy named welsh invented them and he was not american, thats why they dont call them that haha
In Australia they actually spin in the other way
"Put an LS in it."
THANK YOU, Eric!
I get tired, too.
steve
also are you going to paint the engine? I know it's in the car but you haven't shown much.
Haven't shown much? There are about 30 #FairmontProject videos at this point and so much more to go. th-cam.com/video/L22GsHQi7tU/w-d-xo.html
EricTheCarGuy I'm not on the computer much
blue and gold lol. I painted my 351w build scarlet and gray. Gray for the block/heads and scarlet for the rest. GO BUCK'S, stay dirty.
threaded plug defeat the object of a core plug, they aere designed to be a weak link so that if the block freezes as the water expands it pushes the plugs out instead of cracking the block.
I see a lot of trophies back there.
My luck would be when I'm next to that M3 and come to find out by seeing his taillights that it wasn't a ole reg M3 it was a turbo M3 running a 76mm turbo. Lol
I knew that you were going to go boost the first video of the car
The lowly core plug also known by a host of other names such as sand plug, casting plug, freeze plug, frost plug, water jacket plug, coolant plug, block/head plug, expansion plug, expanding plug, welsh plug, welch plug, spring plug, dome plug, dish plug, disc plug, drive plug, soft plug and I feel certain there are other names.
Lol, the Kardashian comment, made me think of Ted 2!
Never lost a "core plug" - I have had the block heater fall out of a diesel... can't replace with a "core plug" because the opening is tapered. Buying a block heater and living in California - embarrassing :-(
They also called em freeze plugs because people would put them in the freezer overnight, shrink em down, then install them.
If you want you can install an efi system and convert the distrubutor and ignition coil into electronic ignition w/ chevy ls series ignition coil pack and for ecu use the microsquirt to increase better horsepower than these
I don't want. My carburetor works excellent. th-cam.com/video/UADOHm6-BJc/w-d-xo.html
Haha! "...the M3 that Daddy bought." Its almost like Eric's shop is near Mason, Oh.... you'd never see a teen from Long Cove driving Daddy's M3, AMG, or 911. Haha!
i hate to be a safety nerd/buzz kill, and i know this was shot months ago but he should really grind the mushroomed end down on his freeze plug driving tool. those metal shards are ready to fly off there.
Those holes are for the core supports.
GO BLUE!!!!!!!!!
