Hello Vanadeo and welcome. I have the same year engine.
Haynes advises compression ratio is 10:1
Comp. pressures 9 to 11 bar, which by my calculations at 1 bar = 14.5 psi is
130.5 psi to 159.5 psi. Max. variation between cylinders = 2 bar = 29 psi.
My engine has done 224,000 miles. The only time the CH has been off was shortly after I acquired the car in 2005 when I found that no.4 plug threads needed a helicoil fitted. Nothing else was attended to as I needed the car back on the road ASAP. I check the compressions when I change the plugs. Last time (210819) they were 195, 190, 190, 195. psi, 1 - 4. That appears rather high but is probably due to the engine never having had a decoke or valves or tappets attended to. But as it is behaving itself at present I will leave it until something needs attention. It does sound rather “rattly” but it has been doing that for some considerable time.
