Was just watching a popular tv show and they put mystery oil in the radiator and started it to tempature to loosen the head studs/bolts on an old flathead ford....... Would it work or is this more tv mumbo jumbo BS?? Thanks
I watched that show too (almost hate to admit it........but I was watching because of the Deuce ) and wondered about it too. I watched with interest because I have a 46 Flathead and the studs aren't moving. I tried heat on one and that didn't do anything, nor did soaking them. It is a long term project so I just pushed it into a corner until I buy one of those stud removal tool sets and let it soak for a while more. Don
I've never used MMO in that way.....but it does loosen sticking valves, lifters and piston rings. Has saved my *** at least 5 times.......and made me some cash. Posted using the Full Custom H.A.M.B. App!
Once you break the seal, it doesn't. The bottle becomes a slippery mess. Keep it away from anything you don't want oiled.
The key with this stuff is to get it hot and then let it sit for a couple days. That's when it works best....cold it takes way longer. Posted using the Full Custom H.A.M.B. App!
I think it was actually 5 they broke, but even that, out of 48 studs isn't all that bad. I was surprised how rusted the ones in my flathead are, they weren't budging and I could see them twisting a little as I was putting pressure on them, so I quit until another day when I can concentrate more on them. They showed them drilling out the remaining pieces of the 5 and tapping threads, so I guess they put helicoils in there because it didn't look like they were able to drill to just the original size threads. But maybe they did. All in all, it wasn't a bad little Deuce though. Don
Soaked all 48 studs with PB Blaster and drove to Harbor Freight. Bought their $7.00 stud remover and drove home. Put impact to stud remover and twisted Harbor Freights 1/2 extension that is part of the tool. Replaced extension with Craftsman and applied impact. Score? Harbor Freight extension zero, broken studs one, removed with impact fourty seven.
I'm gonna have to buy one of those. Do you think the impact helped shock them loose ? I was going to try gently using a breaker bar, but maybe the impact actually works better. Don
The rattling effect from an impact gun DEFINITELY helps! Your breaker bar or ratchet will be a good way to break them...save yourself the time and effort and use an impact gun Posted using the Full Custom H.A.M.B. App!
I was always leery about using the impact gun on a stud remover, especially one of the new style ones. I had a nice old snap on one I gave to a snap on guy to repair and never got back but that's another story. I had very good luck using the impact on an 8ba to remove all the head bolts without breaking one. I'm currently knocking on wood but I've never broken a head stud or bolt in a Flathead v8. Only ever broke 1 stud in a 4 banger.
You would probably have better results running straight Kerosene for a couple of weeks. Kero was commonly used as antifreeze back in the 30s and 40s. It doesnt cool as well as water so it was recommended to remove the thermostat. You want to try and avoid a boilover onto hot exhaust. Some of the Rumely tractors used oil as a coolant.
A 1:1 mixture of acetone and ATF is the best for rusty studs and bolts. Way better than WD-40 or PB Blaster. Don't know about in the radiator though.
I have sprayed studs with creeping lube of your choice, and used a concaved tool in an air chisel to loosen the threads a little. Put the concaved area on the top of the stud like your pushing it into the block more, and don't overdo it. Just a couple blasts with the chisel. You're just trying to vibrate that lube deep into the threads, not stretch the threads
Kerosene just happens to be the main ingredient in WD40 and many other penetrating "oils". If you check the MSDS for penetrating oils you'll find that it's mostly made up of a bunch of kerosene and a little oil, some of them with a couple percent of acid - presumably to dissolve rust. A 90/10 or 80/20 mix of kerosene or diesel and engine/transmission oil in a ordinary spray bottle would probably work as well most of the time, and at a fraction of the cost.
I have found locking two nuts at the top of the stud and giving them some stout cracks with a hammer helps break the grip. Apply your favourite oil first.JW
I know a guy who used to fog his engine with MMO before storing it for the winter. Poured it into the carb until it stalled. Don't know if that was helpful or not. wall
may work if the studs are into the water jacket. You both are aware that you have to worry them once they start to turn right (out a little in a little) because sometimes they have a glob of s rust on the end that will take out the threads or stick them even worse.
Good idea kid. and it will also help break loose some of the 900 years worth of **** in the cooling system.
