done a quick search but cant find much..
have had a few issues with the coupe lately and its looking like stem seals or piston rings.
a few test have been done and although it looks like stem seals the tests dont show anything up..
compression figures are: C1=120, C2=115, C3=110 and C4=120
now i know C2 and C3 can suffer from heat due to turbo etc..
but what should i be hitting? Could this be that the rings are going and thats causing the smoke?
