I adjusted my valves on my 1.7 sohc 2001 civic at full operating temperature and as recently discovered the manual says cold. car has 214000 miles on it. Valves were all about 3 to 4 thousandths loose. Should I redo the valves cold? specs are 9 intake and 11 exhaust. I didnt do the manual procedure either. I just bumped the engine cam lobes downward for every set of valves adjusted (16 valve engine). Honda says adjust all valves per cylinder at same time. After adjustment of valves, new air filter and throttle body cleaning it gained loads of pickup power.
