wagondragon Posted July 10, 2014 Share Posted July 10, 2014 So i have an extra EA82 that has about 90k on it, it was running well until the head gasket went. When i took it apart i noticed one of the cylinders had a pitted rust spot about a quarter of an inch square near the end of the piston stroke. I dont remember it smoking, but it probably was to some extent. Would it be worth boring and getting enlarged pistons if i could do the boring myself? I'm currently going to school as a machinist and may have the correct machines to do it at home. But ive read that the EA82 is not worth boring for cost reasons. Has anyone had a bore job done on their EA82? how did it work out for you? Any and all discussion on this topic is welcome and appreciated.

idosubaru Posted July 10, 2014 Share Posted July 10, 2014 an ER27 6 cylinder XT6 engine is identical to the EA82 - it's the same exact pistons, bearings, rods, valve train, cam seals, crank seals, etc - it just has two more cylinders added to it and a few timing belt and other differences. since the cylinders/pistons are exactly the same, this should be interesting: mr.radon bored out his ER27 here: http://www.subaruxt.com/forum/viewtopic.php?f=13&t=3575&st=0&sk=t&sd=a&hilit=bore&start=60 finished in 2005 - needed headgaskets by 2013. google EA82 bore and you'll get more hits here and elsewhere depending what/why you're asking. 1 Link to comment Share on other sites More sharing options...
Caboobaroo Posted July 10, 2014 Share Posted July 10, 2014 I'm actually about to tear that engine down since I now own it. Has a blown head gasket on #1 and is full of coolant. Hopefully I don't have any pitting in the cylinder but if I do, I will let you know what I end up doing. Link to comment Share on other sites More sharing options...
