fairly sure they should be up over 200 or even 220. although low , your pressures are within 10% so the donk will keep running for a while . Ebay should have loads of CD manuals for cheap take a look there
The old girls lost a little power so did a comp test. 5 cyl's have 160 lb's & 1 has 155. Are they still in tolerance.
I'm also looking for an online workshop manual. Can anyone help.
Thanks all.

160PSI is about right for a stock engine with 9:1 compression ratio.
i wouldn't worry about the one with 155PSI, it's probably just not seating a valve 100%, could be a little carbon on the seat.
140 psi~8:1
150 psi~8.5:1
160 psi~9:1
170 psi~9.5:1
180 psi~10:1
190 psi~10.5:1
I'd be looking elsewhere for your lack of power.

I have given up on compression tests, far too inaccurate in diagnosing issues.
If you have a air compressor, buy yourself a leak down tester.
Correctly used it will tell you the condition and where the issue is coming from, rings, in or ex valves etc
If they are within 5% and shes not burning oil and producing smoke, press the loud pedal a bit deeper to the floor and keep driving.....
