I accidentily posted this thread before it was finished. The title is suppose to be (1985 4Runner "Aretha... DD Build")
Because her name is Aretha, not Gert... SMH
I am a young student who is going to be DDing this thing for a long while ,Lord willing, so this is going to be a simple build based on reliability. I will spend where important and save where not so important. That doesn't mean cheap parts... it just means not the most expensive and nice. So today is the begining: It has low oil pressure, rust on fram and body, and a much needed re-gear for the front axle. My goal is go get all of this taken careof before October. Should be easy given the long deadline. Today I decided to pull the oil pan and make sure my pickup tube isnt all junked up. I also decided to pull the rear fender and check for rust... Not horrible, but not very good either...
So onto the oil pan removal and checkup. Wasn't great news.
Lots of these little plastic pieces all in the bottom of the pan. It seems like they were broken pieces of a timing chain guide from a long time ago in a galaxy far far away. Let's hope when the timing cover was off they replaced them and did so with steel guides. There was little sealant to speak of in the mix of plastic. I cleaned the screen of the pickup tube. I didn't take it off and do a full blown cleanup like I should have, but I'm outside and I don't have anywhere to safely clean it properly.
Eventually I got most of the pieces out. I'm not sure that I got everything as it was difficult to grab them when they got into the crevasses. But 99% of them are out.
I put the pan back up. Let the sealant do it's thing and then gave it a crank. Oil pressure pretty much instantly jumped to right above the 1st line. PERFECT!.... ya not really. When you are driving around the needle is suppose to be at the 3rd line. The one below very top. I let it idel about five minutes. It stayed in the same place. I drove it around all the way to 3,000K in 5th gear.... aaaaaand well... this is as high as the oil pressure guage went.
Wonderful. So anyway, I went back home and let it idle some. By this time it obviously is at operating temp and the oil pressure needle dropped to JUST ABOVE the bottom line. Not just above the first line like before when it wasn't at operating temp, but JUST ABOVE the VERY BOTTOM line. So my next thing to do I guess would be replace the oil pump. If that doesn't fix the problem, MAYBE its the oil sending unit. If not any of those I guess the next option is to do a rebuild? I'm guessing at that point it would mean the low oil pressure means bad bearings and or races?
So I HAVE GOT to figure this oil pressure thing out. I'd like to not destroy my engine.
