First, 50 wieght was never specified when new, nor should it be used today to "mimic" the old oil. Modern multi-grade oil with detergent additives outperforms then best of the old formulations. Second, having high oil pressure doesn't mean your oil is protecting your engine. It simply means that your oil is thick and having a hard time snaking through the oil passages in your engine. You want your oil going to your bearings, not escaping through your high pressure relief valve.

Valvoline also offers a HD 40 weight oil. That HD 50 oil may help the oil pressure readings as well.

The markings came about only because the 80 lb units became available, in order to distinguish between the two. Alan stevenwham 02-15-2012 @ 4:49 PM reply profile send p.m. Member Posts: 5 Joined: Feb 2012 Thanks for your comments, Tom .. and others .. I'll do some evaluation this weekend. Steve TomO 02-15-2012 @ 9:05 AM reply profile send p.m. Senior Posts: 7253 Joined: Oct 2009 Steve, try removing the sending unit and cleaning the threads on it and in the block. The sending unit needs a good ground in order to give an accurate reading. You may have an 80# sending unit with a 50#oil pump. The sending unit should have 50 stamped on the brass fitting. If the 80# unit is installed, your readings would be normal with 10w30 oil. The 50# sending units are getting hard to find. Most of us use 20w 50 oil or straight 30 weight oil. Tom stevenwham 02-13-2012 @ 5:57 PM reply profile send p.m. Member Posts: 5 Joined: Feb 2012 Thanks for all these comments .. I really appreciate the thoughts and advice. I will definitely get the mechanical oil pressure check soon. I drove the car today (for the second time) and noted the following: cold start with temperature around 40 F, the oil pressure read about 18-20. As the engine warmed up the temp dropped to 10-12 and continued to drop while driving around at about 30 mph, eventually settling around 5 (at 30 mph). At idle and relatively warm, the pressure dropped to 2 or so. New gauges. I'll get the mechanical check and report back. Thanks again for your comments.

I agree with the other posts that you get a mechanical gauge to check the oil pressure and post the readings here. Tom trjford8 02-12-2012 @ 8:24 PM reply profile send p.m. Senior Posts: 4215 Joined: Oct 2009 As others have said check the pressure with a mechanical gauge. Spending 120K on a restoration without rebuilding the motor tells me the previous owner had more money than horse sense. I suspect all he wanted to do was show the car and not drive it. There are those folks out there who trailer their cars to every show and don't drive them. It's a great looking 35 and $30,00K for a restored car is not out of line on price. Nice paint jobs today are $6000-8000. Upholstery is $5000-7000. Add in bodywork, tires, radiator, clean up of the running gear, and other miscellaneous parts, etc. you will spend another $7000-9000. Now add the purchase price of the original car prior to restoration and you easily get to $30,000. If you have to rebuild the flathead you will probably spend $5000-6000. If it's an original 35 motor you will have to have the main bearings poured by a shop experienced in building older motors. Again, recheck the oil pressure with a mechanical gauge and get back to us with the results. You may get lucky and not have to do anything but drive and enjoy your new treasure.

After having my engine rebuilt by one of the best in the country the oil pressure still reads low. He said mechanical gauge read normal. Could just be my gauge or sender. I've decided pressure is not as important as flow and figure if any pressure shows I've got oil flowing through and don't worry too much about pressure. I've put 20,000 miles on the engine with the gauge showing low oil pressure without any problems. I wouldn't worry too much about that. Certainly not consider rebuilding the engine again just for that. Old Henry (The older I get, the better old looks.)
