After a month of explaining the intake (the only mod they could prove), they offered to reimburse for the cost of a used engine if I did it my self with before and after pics. I did it in my driveway, and they honored the reimbursement...
Engine # 2
Purchased a used motor (from a wrecked WRX) from a salvage yard. Same everything except this one had 67k on it. 300miles after installation, it started knocking. Exact reason unknown because the salvage yard did a small investigation of sorts, and offered a full refund including shipping....it went straight on the pallet.....I'm buying a damn

If you rebuilt with any of your previous parts like the oil cooler, then pieces of metal were likely still in it and you just reintroduced that back into the next motor - thus killing it, too.

It was modded when I bought it. The owner had a Cobb Ap and was running the wrong map. I was getting feedback knock often and the Dam value was dropping frequently . I changed to a Cobb intake vs the eBay one the car came with , and got a protune by a known tuner with a good rep. After the engine issues , I checked for codes. They where all cam related. There where no codes while driving. I already have a low mileage used engine on the way. I

Model/Year: 2019 wrx premium

Milage: 40,000

EM: Cobb stage 2 91

Mods: Cobb big sf intake, invidia catted turbo back, Perrin AOS, Perrin charge pipe

Fuel: 91

Circumstances: it was -32 here for three days. Car wouldn’t start, finally got started third morning, let warm up for 30 minutes. Left house, coolant temp was at 135. Got on highway, started to accelerate, hit third gear with boost at around 6 psi, and BPV opened and closed for unknown reason. Boost spiked upon BPV closing, and then a bunch of smoke out exhaust and pumped all my oil out exhaust in 10 seconds.

Actual engine failure: hoping just turbo. Need more info?

So much for being a "reliability mod". That's an oxymoron

More of a 350$+ liability mod in my mind, adding connections and things to possibly go wrong.

Yep oftentimes simple is best. Hate to kick a guy when he's down though. Engine failure sucks regardless of circumstances, been there

I think I caught mine frozen before it backed up to far. Drain pipe has been insulated ever since and haven't seen a hint of anything after.

Looking back I sometimes wish I'd gone dual catch when I installed my FP blue. I'd still rather have an AOS than nothing though...

Yes and no.

If ou mod, you SHOULD know what the pros & cons are as well as newly added maintenance.

An AOS is a reliability mod for its function on any turbo car --- keeping oil out of the intake tract or at the very least minimizing it. Over the life of the car, this is a good thing. In the immediate short-term... probably not going to be worth it especially with the majority of the community here keeping these cars for relatively short term.

An AOS can be a liability mod if you do not know how to check or maintain the mod. If you live in an area where freezing temps can take place, you should be running some sort of check list to make sure you are good on all fronts --- one of them being a backed-up & frozen AOS line.

Sound like OP --- no disrespect intended --- thought an AOS was a "reliability" mod where you just install & forget about it. Unfortunately, that is not the case considering the blocked/frozen line that he failed to maintain/resolve.

So, if you know what you are getting into, you will value the mod or not. Routine check ups on mods and general maintenance can help prolong the life of the vehicle as a system and of individual parts as well. If you plan on YOLO-ing the mods, don't be surprised when something goes south...

Pay to play, amiright boiz?

Here is a solid reference for almost any mod. I went through almost all of this and it helped me understand alot of what mods did and why we would do them in the first place. Still reference it from time to time. very well done.

30k miles
Cobb stage 2+ BSF 93 OTS
Wawa 93
Mishimoto intake, Mishimoto catted j pipe, mt45 muffler deletes and xclutch organic 500hp clutch
The clutch blows, wouldnt recommend
Have had the tune and all mods for over a year now (roughly 17k miles). Have had 2 turbo overboost codes about 5k miles apart, DAM dropped once and other than that the occasional -1.41 from bad gas.
Its my daily and i enjoy driving it almost too much.

If you like the car, want it to go faster and have the connections or resources to get cheap work done, do it.

how can cruise control lug the engine though?? cruising at 60mph the computer reads 5-10% throttle. If I see a hill ahead ill speed up for it or go into 5th. This is common knowledge for manual driving. Its not the car's fault its owner is sending it up a hill crawling in 6th. my engine hasn't failed yet, I will make sure to post here when it doesn. I am going to get at least 200,000 miles out of it.

96k rod bearing failure on original oem block 8/29. downshifted to pass. clunk. knock. glitter.

stage 1 since 10k. map stage1 e30 since jan 2020 40k

went big for 2021 at 69k

clutchmasters fx250 360whp

oil changed every 4k penzoil 5w-30
oil temp started to creep before failure

I'm surprised it lasted that long. lots of clean launches, lots of canyons, not abused but driven hard.
putting in an oem shortblock for the daily drive

Its worth another go.

2019 Wrx Limited
27k miles
Mods: aem intake, turboxs Downpipe, gs ebcs, gs tmic, egr/tgv deletes, flex fuel kit, random axle back

Symptoms: excessive blow by, smoke from oil fill/dip stick, rough idle, loss of power.

Literally just got my base map and parts installed right before all of this happened. Not sure how or why but I’m guessing cracked/blown ring lands. Gonna have compression and leak down test here soon… will edit once I find out. Car has been babied since I bought it with 19k miles/ 1 year ago. Oil changes done every 3k. Maintenance in general done accordingly to subarus recommendations.

Model/Year: 2015 WRX Base
Mileage: Approx 58,XXX
EM: Stock
Mods: Stock
Fuel: 91
Oil: 5W-30
Circumstances: Was driving home on the freeway after work. Accelerated to pass a car and got off at my exit (That part of the freeway where this incident happened is at an incline). I immediately started hearing a "knocking sound". I drove the last mile very slowly. Based on videos and other online info I figured the engine failed but couldn't figure out why. I checked the oil and it read as having plenty.
Actual engine failure: Subaru claims that, after teardown, it had only 1.5 quarts of oil which caused major damage. Weird thing is the car didnt have a history of severely burning oil, no leaks, I had the oil changed less than 4 months prior and drove it about 2k miles in that time. Also, the Low Oil Pressure light never came on, before or after the issue
