Question about 1985 Subaru Brat
Slight noise, not bad. Has 230,000 I just got it from a guy who had it 15 yrs. What are the spects and is there any trouble adjusting the valves?
This model does not and uses a hydrallic lash adjuster that works something like the old lifters did. Generally when these collapse or lose hydrallic pressure,a rattling occurs in the valve train. Most generally this is a sign of an oil pressure deficit and may require a new oil pump then hopefully all lash adjusters will pump back up and close the rocker to valve clearance stopping the rattle.

This is actually a Subaru manufacturing fault in the cylinder heads.
Its not the lifters it is a lack of oil supply to the lifters which are in the cylinder heads, through the lubricating orifice which gets blocked and they need to be cleaned out.
Unfortunately the only way that this can be resolved is to do an engine flush 3 times and then on the 3rd one remove the sump and the oil pump and filter and clean these items.
Then replace the oil filter and the oil pump, and sump then it will be ok.
I know this problem too well as I have had 4 of these and had to do this to solve this problem, not to mention the many I have done in a workshop also.
Hope this helps, let me know if you need more information.

SOURCE: I need to adjust the valves
12th inlet and 14 exhaust ,4cyl engine all valves add to 9 ,,example--- no1 down adjust no8 ----no2 down adjust no7 all values add to 9 simple if you take your time to count the valve thats down subtract from 9 and then adjust that number ,this system works on all engine regardless of what the haynes book says ,6 cyl engine then its 13 ,and a 8 cyl engine then 17 ,in cases of 16 valves in a 4 cyl engine then its still the same as two valves work as one ,simple
