I know that most threads on here are age old due the limited number of people here. so I'll add this
After looking at this engine i see several things.
A tiny filter. Not good fixable
An Aluminum oil pump housing Not the best idea.
A tiny oil capacity. Not good. fixable
A slipper follower Cam
There are several things that can help the little engine live a longer and on thing i would NOT do:
First Most people are not aware that the stock oil filter does Not filter cold oil, thick oil, or most oil with over 2500 miles on it (depending on filter size)
All engine that have a full flow oil filter have 2 bypass valves. One is almost always at the pump and is a pressure bypass. and the other can be in the filter itsself or in the block near the filter to let oil bypass the filter when it is clogged, or the oil is flowing too fast to be filtered. like dead cold (thick) oil.
If you were too take a sample of oil every 2oo miles and put a drop on white paper. You would not see much dirt at all for almost 1000 miles (If the engine was sealed up properly and running correctly. ) THEN after 1800 miles you would REALLY see it getting dirty (darker) at a much faster rate. What is happening is that the filter media in Your filter is starting to clog up at a much faster rate than its was when the filter had less miles.
so this is where a Larger filter is better. With a bigger filter media the oil flows slower though it and is filtered better.
So I'd add bigger filter or 2
My other vehicle is a Standard 2006 4.0 Jeep. I run the 2 quart version of the Ford filter on it. www.wixfilters.com/Lookup/PartDetails.aspx?Part=137336 (about 7 inches long)
Now about that aluminum Pump This put the justy engine in a almost special group AMC V8s, Buick V6 & V8s ..... Every one of these suffer form pump housing wear.
What does that is dirty oil. Now it is Normal to have microscopic Iron and other metal in suspension in Your oil. Most all of it small enough in size to go pass right though the oil filter. Some particles (Magnetic) can be caught with this www.shopfiltermag.com/how-it-works/ Once you have used on cut open a filter and see what thy catch.
Disclaimer: I do NOT work for the company, or sell their products. I just use them on my engines. even my RV has one.
Both the above ideas Greatly help with the oil capacity Problem. This will help keep oil temps from getting out of hand.
Remember the Oil IS the Coolant for many parts of the engine,...like the Crankshaft rod and main bearings, valve springs, Cam and followers.
Which brings to the what I would NOT do. Do Not restrict oil flow to the head. Unless you like replacing Cams, followers and valve springs.
I can tell You all I have seen with my own eyes that there is enough friction on a SBC valvetrain to require a Full cooling stystem with the full oiling system. There were NO pistons just an electric motor to spin a straight crankshaft.
once i get my Justy running correctly I will definitely install a remote and larger filter.
