Hi people,
My friend has been offered a chance to buy an SR20 which is down on compression. We tested it and it was 4.5 bar, 8.5 bar, 4 bar, 8.5 bar. So low on all, but especially low on 1 and 3.
Before he goes ahead and does it, is there any easy way to tell what the culprit is likely to be without taking off the head? I think probably ringlands but seems odd that all 4 are suffering the same problem. It's currently in the car and can be spun over (won't start).
Any help would be gratefully received!
Cheers, Jon
