Has anybody had any problems with the piston rings or the valves wearing or not seating properly on a 318i 1988 E30? Compression is a bit low and car seems to lack power. Under load it judders like its missing on one cylinder and seems to miss when cruising but not as bad. Checked for air leaks, cracks, ICV ect, all fine and ive changed more critical components. Any ideas anybody?
Many Thanks
