hi all,

I had several problems with my idle since my timing chain and tensioner replacement...see here 2.5 16v Timing Chain Nightmare!

I bought a compression tester and ran a compression test this evening to see what’s occurring - results as follows:

1 12.2 bar
2 12.8 bar
3 12.9 bar
4 12.8 bar

So, cylinder 1 is slightly down, does anyone have thoughts on that? Bad valve or something? I have no blowback so am confident rings are ok, engine still runs as good as ever from 2000 rpm upwards.....
