October 12, 201411 yr Ok so I was wondering if I my timing belt in my 84 GL Wagon EA81 is an actual belt or if its a chain. And if it is a chain do I need to change it?
October 12, 201411 yr Author Neither. That is the beauty of the ea81. The cam and crank are gear linked. Wow really? Cool beans!!
October 12, 201411 yr Why don't they do it like this anymore? research basic differences of pushrod (OHV) engines and OHC motors.
October 12, 201411 yr I just purchased a 2014 Impreza; imagine how happy I was when i found out the engine (2.0) has a timing chain! Edited October 12, 201411 yr by mr_whirly
October 12, 201411 yr Why don't they do it like this anymore? Auto companies want you to buy a new car every 3 years now, and give their dealership (stealership) mechanics a ton of money until then. Old reliable designs like the Subaru EA series that you can work on yourself don't fit in well with that agenda.. . Edited October 12, 201411 yr by BirdMobile
October 13, 201411 yr And the timing gear setup is why I opted to rebuild my EA81 rather than EJ swap my 83 Wagon. So, just for references sake, all production EA engines before the EA82 were timing gear driven. Starting with the EA82, Subaru started using belts through the EJ's until the EZ engines, which they used timing chains. The belts continued on the EJ engines until their current replacement, the FA and FB engines. #mentaltidbit Sidenote: the EG33 engine used a combination of a timing belt and timing gears. Twitch
