I've seen rebuild kits available for ea81 and some older subaru engine (I think they were Topline) but I haven't been able to find a good comprehensive rebuild kit for this engine
...the ea82 is the 1.8L SPFI SOHC 4-cyl

Anyone know where I can pick one up?

I can sell you a genuine subaru gasket set. Is that what your looking for? EA82 motor are notorious for leaking and commonly need reseals every 40,000-60,000 miles. How many miles do you have on your engine?

hey i have been having the same problem and i finally found a kit with just about everything other then oil pump water pump and timing kit. heres the link.
