If there is anything we do as antique tractor owners that is troublesome is we don’t get our tractors running hot enough under full load often enough. I have successfully and significantly improved running and starting performance on old tractors buy doing nothing more than closing the shutters and making them work for a ½ hour or so. 200 degrees plus. Amazing what will get blown out of the muffler and how clean the inside of the engine gets if you are using detergent oil.

They run too cool ( relative) to get the viscosity improvers in multi grade to thicken the oil. I am not sure of the exact water temp that works the best for multi grade, but I think the 160 deg thermostats would dictate the use of a straight weight oil. A 195 deg one would probably get the oil hot enough to work with multi grade...<o:p></o:p></p><p>Just my $0.02<br>Cecil<o:p></o:p></p><div><p class=MsoNormal>On 11/8/2019 8:41 PM, Ken Knierim wrote:<o:p></o:p></p></div><blockquote style='margin-top:5.0pt;margin-bottom:5.0pt'><div><p class=MsoNormal>Cecil, <o:p></o:p></p><div><p class=MsoNormal> My grandfather (a doctor) had a similar issue with casting sand in a new V-6 Buick (Skylark?) in about 1980. He bought it new off the lot and had trouble with it overheating constantly (over a couple years as I recall), with many trips back and forth to the dealer. At one point it blew one of the tanks off the radiator. After a lot of wrangling (and some strong urging from my uncle, a prominent lawyer in our small hometown, and an offer from my Dad to return it through the dealership with his bulldozer) the dealership finally took the car back in the shop and tore it down. Turns out the block had casting sand blocking the water jacket like you're describing.

The DH had half a 5 gallon bucket of rust and dirt in the block when I tore it down. I find it amazing how resilient that old iron was/is to neglect. Can't get away with that on most of the new stuff anyway.

The car had a bad <br>rear end whine when I bought it. I had a few days off, so I pulled the <br>rear end out and checked the bearings. They were shot. I bought a <br>bearing kit and started to replace the bearings. When I pulled the <br>pinion out the front bearing was galled badly. Further inspection <br>revealed that the passage that carried oil from the sump to the front of <br>the bearing was filled with casting sand. It took a couple of hours <br>with a screwdriver, brake cleaner, and air pressure to get the sand out <br>of the passage. New bearings installed and it sounded fine for another <br>50K miles until I sold it.<br><br>About a year later I picked up a 75 Dodge pickup with 45K miles and a <br>high speed rear end. It also had a bad whine, the reason I bought it <br>for 1/2 price of blue book. Same thing with the casting sand in the <br>pinion oil passage. This one got a new/used 4.10 ratio third member so <br>I did not have to clean out the casting sand. It left with the core..<br><br>In 77 I went to work for the state and the weights and measures agency <br>had a Miller welder on sealed bid that they said always overheated.. I <br>figured a bad head gasket. It had a Chrysler industrial 30. I pulled <br>the head and found a bunch of crud down in the water jacket. I made a <br>tee connection to fit the drain plug holes and filled the water jacket <br>with the water hose then blasted the air to it. It took about 30 <br>minutes and a lot of water to get all the sand out of it. Again it was <br>casting sand. I replaced all the freeze plugs/casting plugs, and bought <br>a freeze plug driver set to install them. I still have the plug drivers.<br><br>What was particularly interesting about these parts, is that they were <br>all Chrysler products. Since then any time I pull a head on an engine I <br>check deep in the water jacket for crud.
