I may have, I honestly can't remember. If I did it was about 4 years ago That's good to know! at least my thinking was not too far off.

Trust me I didn't believe it at first either. That's why I checked it countless times with the powder, and every time it started carrying the powder away right where the dot was. That's the only place I put JB weld and no more leaks. I am on day three and still not a drop under there I roughed it up extremely well and cleaned it twice. Ill keep this updated and let ya know if and when it fails

No corrosion at all, It was a southern car all of its life and I examined all over for other damage and found nothing. I thought the same thing and figured it was from previous damage, however it looked flawless. I made a decent mound of JB weld over a wide area hoping that it will make it stronger and hold up to the oil Pressure at high rpms. I thought about making a test piece of aluminum with a pin hole and an air chuck on it to test the strength of JB weld in a similar situation. I would drill a hole with the smallest bit possible and prep the area the same as I did on the block, jb weld it and crank up the air pressure until it blows apart or maybe not at all. I only have 130 psi available on my compressor but thats more than an oil galley would see.

If the JB weld blows out and I get enough ambition plan b is to weld it shut. My last Legacy had the crank pully come loose and trash the woodruff key slot and end of the crank, I broke out the JB weld and machined it with a file and it shockingly lasted the rest of the time I had the car (about 100,000 Miles). Traded it in with 318k on it.

I just got the car not too long ago and the dealer threw it up on the lift for me when I bought it and everything was covered with oil, I assumed it was the typical subaru leaks. I hope it holds up

I have an 03 Gt and it had an oil leak coming from the front of the engine, it leaked all over the exhaust and smoked quite a bit so I decided to take care of it. I assumed it was the oil pump o-ring or front crank seal, so I replaced them both and resealed the oil pump. I left the timing belt cover off and was checking for leaks after I finished and it was still leaking After drying it off a bunch of times i determined that it was not leaking from the pump, it was leaking just to the left of the pump out of the cylinder or "case half". I took powder (hot coco powder mix to be exact, I ate the left over) and put it in the area too see where it was sticking and washing off and found an extremely tiny pinhole or defect in the cast. It must be in a pressurized oil galley because it leaks alot more at high rpm. I couldn't even see the hole or defect or whatever you want to call it. Either way I cleaned it up, roughed the surface, cleaned it again and got out the JB weld. I assume it has been there since new, Seems to be holding up so far!

Is there a way to tell? I looked up the numbers on the top where the trans meets the engine and didn't find anything.

Oh ok, Thanks. That makes sense. I also wondered if the front differential or any other gears be different causing problems.

I have an 03 Legacy GT automatic with Sportshift, Does anyone know if a transmission from a regular Legacy without sportshift will work. According to the cross reference chart on all of the transmissions for sale on ebay, they will fit. So that makes me wonder if they are the same trans but work with or without that feature. I don't even need one but I am just obsessive and like to know these things about my car just in case. Thanks
