I have a C135 engine in a 404 and I'm getting a flickering oil pressure light at low speeds and a solid light at low idle. I'm going to install a new pressure switch tonight and check the actual pressure with a gauge. I'm wondering what I should expect to see.

I don't imagine these engines carry much pressure at idle but I've no idea what the minimum should be before I should worry.

As always, help is appreciated!

No you didn't, you just thought it was, because most all of us get off-topic a LOT, but that's okay, though!

As for your oil pressure, I have a Farmall 404 also, and playing around with the wires up under the dash will get most of my instruments working again. The problem was corrosion.

Now, if your tractor smokes and runs like it's knocking, now there's a concern that your engine needs rebuilding. Try playing around with the wires and replace that sender. You should be running around 10 pounds or so at lowww idle.
