987687 Posted April 15, 2012 Share Posted April 15, 2012 It is an interference motor, but its a pushrod motor, so assuming it is assembled correctly, there is zero chance of pistons hitting valves. The ea81 is interference? Really? If it is, valve float could mate pistons and valves. Quote Link to comment Share on other sites More sharing options...

987687 Posted April 15, 2012 Share Posted April 15, 2012 Given my abuse of the ea81, it's not interference... The ea82 isn't, I don't see why the ea81 would be. But dunno, hopefully someone chimes in on the matter. Quote Link to comment Share on other sites More sharing options...

J.T.R Posted April 15, 2012 Share Posted April 15, 2012 Nice Job, some day I would like to have a shop where I can spend my time doing things like this. Quote Link to comment Share on other sites More sharing options...
Idasho Posted April 15, 2012 Author Share Posted April 15, 2012 Everyone loves pitchers... or was is pictures.... After half a gallon of purple power, and a bit of pressure washing, the trans was deemed clean enough to make pretty. New axles seals were installed This is that 4wd shift linkage seal mentioned before. And associated sensors used. 4wd and reverse. Anyone know if these are still available new? The 4wd sensor has some cracked insulators on the wires. Id like to replace it. Quote Link to comment Share on other sites More sharing options...

Idasho Posted April 23, 2012 Author Share Posted April 23, 2012 So my pistons and rings FINALLY came in. So I was able to do some work on this motor. EA82 SPFI pistons and rings Checking ring gap... Then each piston was fitted with new rings. And I started dropping in pistons Clips installed Top dead center. Quote Link to comment Share on other sites More sharing options...
Idasho Posted April 23, 2012 Author Share Posted April 23, 2012 Then the flywheel housing went on... All fasteners installed with a bit of loctite Sealed up NICE Quote Link to comment Share on other sites More sharing options...
Idasho Posted April 23, 2012 Author Share Posted April 23, 2012 Brand new oil pump installed... Then the heads went back on with Felpro permatorque head gaskets. hydro lifters and pushrods... Quote Link to comment Share on other sites More sharing options...
Idasho Posted April 23, 2012 Author Share Posted April 23, 2012 Then the motor was flipped over... Oil pickup tube installed. Valve covers installed for now to keep things clean... And oil pan installed. Toyota oil pan RTV used here. And finally, motor tossed back on the bench, but not before installing a new water pump... The motor will remain like this for a while. I have a customers car to get into the shop for a clutch job. This project will go on hold for a bit. Quote Link to comment Share on other sites More sharing options...

Crazyeights Posted April 24, 2012 Share Posted April 24, 2012 Beautiful work! I also know how much extra work it is to stop, wash your hands at every step, and take such nice pictures. Just curious as I am doing 1 last EA81 myself. What if anything was done to the cam and lifters? Are they put back just like they were, reground, or? I had bad luck with the torque grind on my last hi-performance build and I am thinking of just putting the stock used ones back in. Quote Link to comment Share on other sites More sharing options...
Idasho Posted April 24, 2012 Author Share Posted April 24, 2012 It does take a bit, though my camera is always a bit oily Generally my hands are always oiled, until I install gaskets or seals. Then they get scrubbed and dried. Keeping them oiled throughout most of the build assures that skin oils do not interact with the metals, keeps things lubed, and actually helps keep your hands clean. As long as the cam lobes look good, and there is no nasty wear on the lifters, orientation/matching doesnt matter. All of these lifters looked great, and no wear that I could see/feel. The cam looked to have some wear, but this is the first Subaru engine Ive had apart, and from looking at some subaru cam lobe pictures online, they all look a little funny. Incomplete casting is the biggest issue Ive seen. I mic'd all of the lobes on this cam and they were all well within spec. So I ran with it. I had considered a torque grind for this build, but I figured for a (mostly) street driven car, just bumping the compression + weber + 5-speed should be just fine.

Crazyeights Posted April 24, 2012 Share Posted April 24, 2012 It will, and you still maintain all of the good low end driveability traits that seem to go away with the torque grind. Quote Link to comment Share on other sites More sharing options...

Idasho Posted May 1, 2012 Author Share Posted May 1, 2012 Thanks! Sooner or later Ill get back to it. For now it sits on the bench. It looks like the customers car I have in the shop for a clutch job is going to get expensive real fast... I drained this out of the manual trans... It is supposed to be a nice rose red ATF. It smells like gear oil, and is basically liquid metal The previous owner did a hell of a number on this car... Quote Link to comment Share on other sites More sharing options...
