Question #2 where does the oil pressure guage fitting go into the engine? My oil pressure guage appears to be plumbed into the hydraulic pump and gives a constant reading regardless of engine speed.

It holds a reading of 60 on the gauge all of the time. This is really a tight engine.. compression is spot-on all cylinders, oil pressure is evidently good. Only 1530 hours on engine when I got the tractor (Hour meter still worked on proof meter) I was lucky I guess. Had to do a few things but not a whole overhaul like a lot of folks have to do.

He has done several Ford 4 cylinder engines like mine and said that in his opinion as long as I had 60 psi with 15-40 Rotella I was good to go. I don't know if engine has been rebuilt or not. He said from compression numbers and the general looks of things it more than likely has and that new oil pumps they sell now are set up like the old industrial engine pumps were for higher psi and it is not unusual for them to give 60-70 psi. He listened to the engine with a stethoscope and said that the bottom end sounded smooth. He said to use the machine and as long as the oil pressure comes up fast and stays up not to worry about it.

I'd VERIFY it.. vs getting the opinion of someone. even a very smart someone. verified data beats opinion every time. have a good one. my last post on this. soundguy [Reply]  [No Email]

I was just trying to get answers to a question and although I got another opinion it was in no way intended to slight you or belittle your knowledge. I have enjoyed the tractor hobby, and intend to continue thusly.I engage in this hobby for relaxation and relief from the stress of a high pressure job. It is not my intent to hassle anyone or to be hassled. I apologize to the members of this forum if I have spoken improperly or acted in any way other than collegially and honorably. Thanks to all of you for all of your help with my project. Bill [Reply]  [No Email]
