Hello! I actually don't own a tractor, but I do own a '63 Checker Marathon auto with the Continental F226 OHV 140 hp motor that I know is used in all kinds of tractors and other industrial equipment. I bought this Checker three weeks ago (I own two others; they are the tractors of the auto world) and just drove it today, after an oil change. I show 12-15 psi at cold startup, and 15-18 psi at speed (est. 2500-2800 rpm at 55 mph). I use 10w-30 oil. I can't seem to find anywhere what the normal oil pressure is. The hottest this engine has gotten so far (thermometer in the radiator tank) is 135 deg. f. It runs extremely well. Any thoughts? Nice site, by the way. There are some really nice classic and antique tractors around these parts.

I've been restoring the interior, so I finally got around to adding a mechanical oil pressure gage and I am currently showing 32-35 psi at start up (running straight 30 w and Lucas oil stabilizer) and settling down to a 28-30 psi after warming up. the needle stays rock steady, no fluttering. I've let this car run for thirty minutes sitting, and it stays at 28+ psi. Revving up to an estimated 2500 rpm shows 40+. I guess I'm okay for awhile. Thanks!

The "rule of thumb" I've always heard is you need at least 10 psi of oil pressure for each 1000 RPM of engine speed. In other words if your holding 5 psi at 500 RPM idle speed and then getting at least 36psi at high idle of 3600 RPM then the engine will be just fine. My old J-10 Jeep has a 360 AMC engine in it. I'm used to a small block Chevy with abundant oil pressure so I was worried, when I bought it, that it didn't hold much more than the pressures I just mentioned. It's been holding the same pressures for nearly 12 years now and still running strong.

After a rebuild, my Senior oil pressure gauge is pegged out at 45 pounds

Thanks guys. I'm going to hook another gauge to it, like y'all said, and see where she's going. I'm also going to keep checking the oil level and track mileage, as I'm already smelling gas in the oil. I figure the rings have some blowby. The plugs I took out were carboned from running rich but didn't show any evidence of top-end oil burning. It smokes a little on starting but goes away. No loud clunks, screeches, ticking, etc.

If you do a little research on the 226 Continental, I think you'll find that the Kaiser-Fraser people consider they have a weak lower end, so don't be surprised if you need new inserts. Overhead valves was an optional engine. Most of us think of Continental flatheads, or Jeep (Continental) Overhead Cam engines.
In 1965 Checker started using the Chevrolet OHV Six. Maybe that's what yours has by now.

That engine in a Kaiser- Frazer called for 35 lbs. oil pressure 47-50, in 51 they jacked it to 40 lbs. but in 53 they were back to 35 lbs. I would think your Checker should be about the same. I would check with a known good gauge before tearing into the engine.
