1979subiebrat

It appears to be a complete pump, ill find out when it shows up lol I went ahead and ordered one and should be here by the weekend. I'm still gonna take the old one off and apart just for curiosity sake. I got this brat as a quick turnaround project for some cash to go towards my Fj. But the more I work on it and drive it around the yard the more its growing on me. So far I've only got an old canoe invested in it and a gasket set. I keep envisioning a lift kit and new bumpers, but only if I decide to keep it lol

I will take the pump off this weekend and take pictures as I go through it, thanks for the diagrams. That should make it easy to get apart and figure out. I did find a new pump on eBay for 40$, which may be worth a shot compared the autozone one. It's made by a Japanese company I've never heard of though. eBay item number 270714892427

Sounds like I guessed right. I took out that Allen plug on the bottom side of the pump and put my guage in there. With the engine cold it was reading right at 50 psi. When I got the engine warmed up the pressure dropped to 10psi. When the light starts to flicker the pressure is dropping to about 8psi and bouncing between there and 10psi. I turned the idle up to 1000rpm and the pressure stays at a constant 10psi.

Wow, I think I need to get one of those manuals. The guy gave me his old chiltons manual with the brat when I picked it up and it doesn't have anything like that in it. Doesn't surprise me much after I read the electrical section and it said that wiring has become to complex to provide detailed diagrams in a reasonable amount of pages. Haha Thanks for those diagrams btw ill post pressure specs when I get home this evening.

I will try to find an external gauge to plug In today. The pickup for the pump has a screen in the oil pan, I cleaned it when I had the motor out putting new gaskets in it. It has a new filter and fresh oil as well, 10w-30. It just seems odd to me that when cold I can idle it real low around 500 or so before the oil pressure light even begins to flicker. But when warm idling at around 800 it'll just start to flicker unless you give it a little throttle. This is my first subie motor to work on and they are pretty neat, but can be frustrating like any other motor. Thanks for the replys and ill look at mine again tonight after work. Ill try to add more pictures too of before and after the pressure washer. Good pictures of these old 1st gens aren't real easy to find I've noticed.

I will try but it keeps telling me my pictures are all too big to attach, is there a better way to post pictures on here? I'm new at posting to forums, I usually just read them lol.

Still trying to figure out how to add pictures on here, sorry

Here's what she looks like all cleaned up

I got this old brat on a trade, what y'all think? It's a one owner but hasn't been driven in 10 years. The motor had been taken apart and left for the rats to live in and chew one. I've got it cleaned up and put back together, but when it warms up at idle the oil pressure light begins to blink on and off. Is this common with these old motors or is the oil pump just weak?

I just realized I posted this in the wrong spot, sorry
