Hehe, since you live in Iceland, I think it's okay for you not to know what that stands for (since it is an english acronym).

DOHC = Dual OverHead Cam

Most of the engines in our first gens (except yours and other european mx6's) are the 2.2L SOHC (Single OverHead Cam).

So this dual overhed cam, is this the same as a twin cam ??

If so do they operate independantly of each other, or what exactly do they do... another stupid question...

cams

In a DOHC, One came is for exhaust and one is for intake, make the process more effecient in exchanging gasses. Other than that, you would have to ask a more knowledgable person to get specifics.

i strongly doubt that Fe3 had varible cam timing(i can be wrong :x)... the cams do work independantly though are driven by one belt

DOHC system also has better performance over its SOHC and OHV(over head valves) systems...... its easy to see that *cough* Honda *cough*, toyota, nissan..... most (if not all) use DOHC system........ DOHC system is also applicable to V shaped blockes but then its known as QOHC(quad overhead cam, ie two cams on each V part) like the amazing Lexus V8 4.0L...... many poeple refer to V shape beeing a DOHC..... wich seems correct, but is totaly untrue :rolleyes:, V has two cams but it is still SOHC system (oviosly not all V have that :p )

hope that clears some water :)
