Update:

I got the first rod bearing out, took about 30min. The bearing looks typical for a bearing that was oil starved. But really not too bad. I hope to have the other 2 out later today.

I could have made a shirt with all the lint. This explains why it ran fine for awhile. I bought a Fram filter even though I hate them...now I really think they are junk.

You had previously cleaned out the inside of the pan with a linty rag? If the pickup is clogged, it's not the filter's fault, as the filter is after the pickup.

The engine ran long enough to cycle the oil. It ran great for 5 mins. Here is a good read about filters:

Here is a letter from a fram worker:

Take it with a grain of salt like anything on the net.

I'm not trying to be an ass here, but I wanna know who told you this, coz it's BS.

No bottom-end failure of any kind is "common" to a Subaru, period. Look at evolutionmovement. Almost 250k hard-driven miles on his old NA engine, and he thought he blew a piston, but in the end he only sucked an exhaust valve, still no bottom end damage. boostjunkie, who sold his Legacy Turbo to vrg3 due to an accident, has 210k some miles on an engine which ran 17lbs of boost, and roughly 230-250 crank HP, and again was driven quite hard. Legacy777 is quite the leadfoot too, and his Legacy has some 180k on it, again no bottom-end problems there either. My Legacy only has 136k on it, and if I was stupid enough to tear apart a perfectly working engine, I'd put money down that I'll find negligible, if any, wear signs at all on any part of the engine, that's how smooth it runs.

Read the first post in the EJ22T info thread stickied in this forum to see just how tough an EJ22T block is.

And not forgetting the rest of the EJ line, as many headgaskets blow on the Phase I EJ25's, there still is a VERY low number of bottom-end failures on the EJ25. The EJ20 is no exception, the EG33 again a very good engine.

Subaru bottom-end failures are extremely rare, from the EA71's of the 70's to the EJ25's of today.

The only way I can imagine your engine losing a bearing, Dan, is oil starvation. I don't think you could have even driven it too hard to do that.

I'm not saying they have weak bottom ends, but the conrod bearings are the weak point. Here is a good thread.

Mine was due to oil starvation...not driving.

Okay, I can see what you're saying...

If the EJ22G is a chain that can hold 100,000 lbs, then the rod bearings are the link that can only hold 80,000 lbs

Nah big ends are the weak point of some EJ's. The ej's in question are EJ20H and EJ20R from the BG/BD TT legacy range. Rod bearings are a very comin failures in these engines even if they are completely stock. The stress of the TT system means they let go if the cars had a hard life.

Well #3 rod bearing was toast. It was beat to hell. #2 was fine, just a little grooved. #4 bearing was mint. I couldn't get to #1 bearing so lets hope it holds out. All new bearings are installed, this is very much a temp fix. Hopefully it will last till spring when I can fix it the right way and maybe add a stroker kit. I kinda wonder how long it's had a bad bearings. I ran it for maybe 10 mins only, the bearings is shinny and flatten out. The crank looks to be in fine shape, luckily. I heard that if I order a new crank for the EJ22T that it's weaker then the original?? When I do the rebuild I will have a machine shop take a look at it.

It pays to have a family friend that owns a machine shop. You have no idea how much work I own the guys. He fixes my messes and doesn't charge a thing. I really need to drop in and clean his shop for him. He is an older guy, and still follows old school thinking of doing it right or not doing it at all. Other shops in the area take the easy path and build a crap motor.
