  1. I finally pulled the short block (SOA478H600R1) that I purchased a couple months ago out of the box and put onto a stand. Changed out the 7mm oil pump for a 9mm that I had (I don't think I'll need a 10mm as I'm a conservative driver, and this is just for a DD project). Looking at the pistons, they're labeled as 255 SH. Is this going to be a problem mounting with DOHC heads? When I was talking with a subaru parts tech over the phone I had specified that I wanted an EJ251 or EJ253 short block for '03-'05, and they had given me the part number. I had then talked with a different Parts Tech, and they confirmed that that part number was for what I had specified. Are the pistons the same? I thought the 255s were used with the AVL systems, and can't work with pre-AVLS. . Should I be looking for new pistons now? The current motor in my car is an EJ from a 2001 Impreza, with DOHC heads. I wanted to recreate the build as it is generally a nice and powerful (enough) motor. Also, I bought a brand new subaru water pump because I thought the stock one that came on the block was supposed to be forward facing.... What showed up is identical to the spare I bought. They are identical, right? Thanks all, Greg
  2. The 'time' side of my maintenance schedule says my car needs a timing belt. The car has only 51,000 miles but is an 06 (delivered in October of 05). This would be my first Subaru timing belt and I think I'm gonna have some questions and probably need some moral support. (actually, the ONLY T-belt I've ever installed was on a 1978 Civic wagon ! - that was belt only too) first, it appears my car has an ej255 engine. I think I'd like to get parts from either theimportexperts or mizumoauto on ebay, however, the compatibility/'selection scheme' often says my car isn't compatible. Still, a coupla links that 'look' good are ; http://www.ebay.com/itm/371001013292?_trksid=p2055119.m1438.l2649&ssPageName=STRK%3AMEBIDX%3AIT and http://www.ebay.com/itm/261044896184?_trksid=p2055119.m1438.l2649&ssPageName=STRK%3AMEBIDX%3AIT#vi-ilComp look OK? Also, I'd rather not do any work/spend money that folks would consider unnecessary. Mostly because of risk due to my inexperience. I DON"T mind working on the car for 2-3 days or paying for good parts, so IF I change the waterpump (would you change it at 51K miles?), I'm gonna get an Aisin. I know nothing about the GMB parts listed in one of those links and am leaning toward the more expensive NTN w'ever parts. Many people seem to think I should change the water pump and the cam and crank seals (remember - 51,000 miles ) but, as for the seals, it seems there's some 'art'/skill involved, and maybe I'd need a special tool to remove them - maybe to seat them as well. Plus, I've never used the sealants you guys talk about, Ulta grey or anaerobic? Couple that with stories of cracking cam pulleys(there's 4 of them!) and needing to sand-down (?) some shaft surfaces - I kinda feel like it might be too risky for me to tackle the seals unless I see leaks? I'd like a link to the FSM for this job if someone knows it (2006 WRX Wagon) Does everyone pull the oil pump and re-seal the back of it? Can I just leave it alone? What size socket is needed for the crank pulley? (in case i need to get a 6-point for my impact) Will I need to use any of the following; sealants (what types?), anti-seize(where?) ,threadlocker (where?), grease or special lube (where?) For a first timer, would you recommend pulling the radiator? probably install new hoses if I do but ??? any parts easily damaged plastic or hardware that will likely need replacing along the way? (clips,screws, bolts, nuts) any suggestions for the major 'gotchas' to watch out for? any decent pics or videos around? I have hardware stores near enough, dealer is 17 miles away. I don't expect someone to respond to everything, but I will listen to any wisdom you guys want to pass along. naturally, I have to live with any compromises I make, just wondering what experienced mechs have to say. If waterpumps leak coolant instead of seizing their bearings, I might leave mine in for instance.
