Freeze plugs are the stupidest thing ever invented

So I finally fix the jeeps timing issue and get it to idle yesterday, but a second freeze plug starts leaking. This morning I take a hammer and punch to it to get it out and replaced. But to my surprise, I was punching on the wrong freeze plug!

It's the plug on the left I shoulda been smacking on, but I broke the one on the right! Doh

Ok now I gotta take the manifold off and do all the freeze plugs before yet another one goes! I guess it's a blessing in disguise cause now they'll all be fixed right.

But my point that freeze plugs are stupid is still valid. They never work. If your engine freezes, it breaks the block anyway. The flimsy freeze plugs don't help, and they'll just leak over time. Stupid invention I tell you.

I would say those plugged holes where meant more for pouring put the casting sands than for freeze protection

Why would the stupid dorman kit only give me 4 freeze plugs and a fifth one that is larger !Attachment 465145

Yeah I did read that just a bit ago. Oh well, I may be wrong about what they are for but still stupid that these leaked like that. Put some threads on them and screw them in, dono. Oh well. At least mine I'll be 80% good. Lol

Correct. Casting holes to remove the casting sand. The misconception is that the freeze plugs are in place to keep the block from cracking when the coolant freezes. The heads usually crack before the block. Freeze plug contamination may be from an acidic condition in the coolant. If it were me, I'd replace all.

Got it together with all new freeze plugs and got her started. Purs like a kitten. Runs great. Throws no codes. Love it. Burned all the oil off and ready for the next step. Gotta instal the transfer case and driveshaft. But dinner first. The next step is gonna wait.

When I started it the third time it all the sudden came up to a perfect idle and ran just like a Timex. It was awesome. Have I said before, I love this stuff.

96 would have been throttle body injection or carburetor?

Air/Idle Control Valve does wonders. Expect a O2 Sensor to tell you to replace the Converter down the road. I hope it doesn't but I've drug my fair share of 4 wheels out from under a tree where it's been for 2-5 years. Seems most that are FI with O2 Sensors end up with Converter issues. Like your project my wife sees me drag stuff in my shop with the Bobcat the junk yard won't take for Scrap Metal. The Mercedes had not been on the road for over 2 years, I gave the kid $1800 for it.

Oh what a travesty. Some poor person takes the trouble to crawl under your vehicle and cut the cat of. Just to find out someone has removed all the precious metals.

One question I have never seen a satisfactory answer on is why when all engines are manufactured Brass Expansion Plugs are not installed at that time. If you buy a Marine GM engine it has brass or at least they use to.

They don't want them to last forever

On my 1990 Geo Tracker I removed the cat completely. The will cause problems down the road.

When I went to germany back in the day, American vehicles with catalytic converters on them, had them removed and a plain piece of pipe installed in it's place. Regular fuel only. If upon your return and you shipped your vehicle back, it was replaced.
