Thanks for thoughts. All plugs were out, I was told it was in regular short journey use, but can't be sure. I might try test again, it's a new Sealey gauge so should be ok, maybe it was the way I was using it, never done compression test before. I thought the readings would go up when oil added. I think there is some blow by, hence the oil splatter. I want to keep it as a rolling resto, so wanted engine running as best as I can whilst sorting doors out etc. Thank you Jh

Hi all, looking for some advice, I purchased '66 1200 estate just before xmas. MOT'd and a driver, but low on power, usual oil splatter from oil breather cap. Done a compression test with engine warm, accelerator pedal held fully down. Dry readings: 1 = 100, 2=145, 3=100, 4=140 then with 2.5ml of oil in pots 1=110, 2=110, 3=110, 4=110 Does this indicate that new piston rings are required. Engine is GA209899HE, with I believe hardened valve seats for unleaded, as there is a bill for that work in the paper file. No.1 PLUG was a bit sooted up, compared to the rest. Thanks JH
