Rusty_OToole Posted September 20, 2015 Share Posted September 20, 2015 I did mine by prying out the core plugs and washing with a pressure washer then putting in new core plugs. The water jacket was about half full of mud and rust. This on a 51 Dodge flathead six. Link to comment Share on other sites More sharing options...
JACK M Posted September 21, 2015 Share Posted September 21, 2015 I agree, the only way to do it right is with a coat hanger and water pressure.A messy job. Link to comment Share on other sites More sharing options...
Graham Man Posted September 21, 2015 Share Posted September 21, 2015 I used a power washer in my engine also...lots of sand and rust particles around the cylinder sleeves. It was a big mess but the rear cylinder was about half full of mud. I used wires to get back were the pressure washer was having a hard time. I think you need to physically remove the sand & rust, a chemical answer would also eat the block at the same time. Make sure you have a water distribution plate if your car had one! Most of them were steal and rusted completely gone, check with someone who is an expert on your engine. What I did different was after I put the engine back together I picked up a house style water filter about $30 at any home center, you want a clear unit (higher melting point) and temporarily put it in your heater hose. The 5 micron filter worked great, completely filled my filter twice before it ran clear. Best part is it cleans the engine while you are driving and if it gets plugged you do not hurt anything. My engine never even comes close to overheating anymore. Use the old fashion green antifreeze nothing fancy just the $10 non-mixed stuff and change it out every 5-7 years (that is a another story) Link to comment Share on other sites More sharing options...
K8096 Posted September 24, 2015 Share Posted September 24, 2015 Magnets work good too. They get rusty metal chunks as well the fine stuff. Link to comment Share on other sites More sharing options...

Larry Schramm Posted September 29, 2015 Share Posted September 29, 2015 Interesting. What would happen if you attached the hose to the bottom connection instead of the top and then blasted is with air? Link to comment Share on other sites More sharing options...
61polara Posted September 29, 2015 Share Posted September 29, 2015 That's the normal flow of the water. Reverse flushing removes more scale and rust. Too bad he showed this on a clean engine. You should see what comes out of a normal engine needing a flush. Link to comment Share on other sites More sharing options...
Graham Man Posted September 29, 2015 Share Posted September 29, 2015 (edited) Please pull off your water jacket. Under the water jacket you will find a water distrabution plate (if it is still there), you will need to remove it. Get back to us on what you find, you might save yourself an engine rebuild.
