April 12, 201213 yr No timing chain/gears/belts. I was under the impression that the Cams were gear driven? I haven't taken my engine apart yet lol.. That comes later
April 12, 201213 yr Author I was under the impression that the Cams were gear driven? I haven't taken my engine apart yet lol.. That comes later There is a gear inbetween the crankshaft and camshaft, the crankshaft turns the gear which in turn; turns the camshaft. The camshaft pushes lifters which push the "pushrods"; which operate the rockerarms; controlling the valves. Edited April 12, 201213 yr by 6 Star got the lifters and pushrods backwards. xD

April 12, 201213 yr WAIT! so ea81's are not ohc? and i know that ea82's are, so witch one of the two motors makes more power/torque/is cheaper to maintain?
April 12, 201213 yr Author WAIT! so ea81's are not ohc? and i know that ea82's are, so witch one of the two motors makes more power/torque/is cheaper to maintain? They are ohv. The ea82s make more power and torque, the ea81 is cheaper to maintain. That yours?
April 12, 201213 yr WAIT! so ea81's are not ohc? and i know that ea82's are, so witch one of the two motors makes more power/torque/is cheaper to maintain? Yes, EA81s are OHV with Pushrods. They probably make about the same power/torque being that they are both 1781cc motors. I personally think either motor is easy and cheap to maintain. Getting the correct parts for an EA81 is tuff sometimes (Just getting to old)

April 12, 201213 yr witch of the two is easier to upgrade? You can stick MPFI onto the EA82 easier, given you have the intake and the ECU and some wiring. EA81 might have more options since its popular with the Aeronautical world.

It's directly driven off the crank, and therefor, turns the opposite direction. Stolen from Idasho's rebuild thread: The crank gear is hiding behind the flywheel mounting flange.

Stolen from Idasho's rebuild thread: The crank gear is hiding behind the flywheel mounting flange. there is a better pic on that thread that illustrates the idea more clearly, but thats funny cause i thought about this post as well when i looked at idasho's thread.

Guess I forget some things every day. :-p Being that I didn't have a photo on hand at the time I was just going off of memory. I've taken these things apart numerous times. Heres a link to the ea81 I refurbished in my Brat (post 54): http://www.ultimatesubaru.org/forum/showthread.php?t=125967&page=6 Edited April 13, 201213 yr by 6 Star
April 13, 201213 yr Seems like almost All the Pictures posted on this Thread, where First posted on the "Strange & Weird Subaru Stuff Thread" ... Really. Well... Nevermind. This Picture is from that Thread, the Subaru "Art Car" DL: It hasn't been Posted here Yet, isn't it? Kind Regards.
April 13, 201213 yr Author Loyale2.7Turbo, some of them have indeed come from your thread, but that is because they are so cool they have to be shared more. I think the ratio of pictures not from that thread to pictures from that thread is pretty great though. Wish I had a welder.
April 13, 201213 yr Loyale 2.7 Turbo, some of them have indeed come from your thread, but that is because they are so cool they have to be shared more. ... Well, I Agree... ...No Problem! _______________________ Here is Another Honduran Nice Subaru: I Took this Picture with my Cellphone, The Subaru Loyale Wagon was Parked at the Shoppin' Mall's Supermarket; it Sits on 17" Tires... ...That Subaru Belongs to Andres... here is his "CarDomain" Web Link: http://www.cardomain.com/ride/3867148/1985-subaru-dl More Pictures: I'll Try to Contact him and invite here to Join us...
