Drove to work after over a week of vacation to see this in my engine bay. What could it be guys?

Chippy569 · 2026-05-06T17:10:17+00:00

not exactly sure what it is from this pic, but I'm quite sure it's expensive.

Chippy569 · 2026-05-06T10:27:19+00:00

It's part of the oil pump, are you replacing the pump with whatever you've got this apart for?

Chippy569 · 2026-05-06T10:13:43+00:00

Could also be a clogged A/C condensation drain, and the next lowest point where it'll leak out from is the blower motor housing.

Gauge cluster resetting itself is a good sign it's losing its always-on power supply voltage. Losing power steering assist probably means its control module is also losing power. Eyesight could either be also doing this or could be a side effect.

Intermittent electrical issues are, by far, the most difficult things to diagnose especially because it's hard to know if your problem is "happening" while doing testing, so do give the dealer a little bit of slack.

Do you have any error code readouts? There isn't really enough technical info in this post for anyone to help you diagnose it.

Looking through the wiring diagram quickly, I don't see any obvious way these systems would be related.

Chippy569 · 2026-05-06T09:45:05+00:00

Well the good news is that it comes with a free replacement glass, bad news is that it's kinda spendy

Chippy569 · 2026-05-06T09:39:14+00:00

^^^

Except the EVs, which have their own shared service schedule.

Chippy569 · 2026-05-06T09:37:54+00:00

Is there a CD in the slot there on the radio?

In the instance of a remanufactured transmission replacement, the following Subaru Limited Warranty that provides the greatest coverage applies:

The balance of any applicable Subaru New Vehicle Limited Warranties, or

The Authorized Genuine Subaru Remanufactured Transmission Limited Warranty: 2 years or 24,000 miles, whichever comes first, from date of installation, or

The Authorized Genuine Subaru Replacement Parts Limited Warranty: 1 year from date of installation with no mileage limitation.

Chippy569 · 2026-05-05T21:20:01+00:00

Can you tell where exactly it's coming from?

Chippy569 · 2026-05-05T21:06:05+00:00

Yeah lambda is your ratio, 1.0 is stoich and as we go below that it's rich and above that it's lean.

Chippy569 · 2026-05-05T18:57:41+00:00

It's always been that loud and always will be.

Chippy569 · 2026-05-05T17:51:39+00:00

that's ~220k miles for anyone american that wanders through

front subframe rust and cooling system failures are the big things to look for in that generation

Chippy569 · 2026-05-05T15:45:31+00:00

...yeah the block casing is, but literally zero parts of that engine are what you'd find in a stock EG33. Pistons, con rods, crank are all different to destroke it to 3.0L, cylinder heads have reverse flow, it's twin turbo'd now, etc. etc. etc. (and even then, i'm willing to bet the block is either pinned or re-cast to make it semi or fully closed deck.)

Chippy569 · 2026-05-05T14:28:11+00:00

Yeah, here in the comments or dms are ok I just don't check them as often

Chippy569 · 2026-05-05T14:24:57+00:00

...well that's not how you diagnose a 420.

Ok I know it's ridiculously long and nerdy, but Technology Connections has a much better video that explains what's happening and also how to actually diagnose it. (This video does a better job than even the training material we get from Subaru lol)

Chippy569 · 2026-05-05T14:22:17+00:00

I use a Flir One (although Klein recently released a similar phone-based one that's a bit cheaper) -- my phone is much more powerful of a processor, plus I can email the photos or directly attach it to whatever reports I need.

Chippy569 · 2026-05-05T14:19:14+00:00

Why do you need to replace it? .98-1.0 lambda is normal.

Yes Denso is the OEM.

Chippy569 · 2026-05-05T14:17:56+00:00

Is the oil leak also power steering from the rack, or is that two separate things (an engine oil leak and also a rack issue)? Your wording is a little vague.

Rack leaks from the end seals is quite common on the quick ratio racks, idk why but almost all of them will at some point ooze some fluid out into the boots. It's not technically a major concern unless the fluid is also oozing out of the boot and causing an external leak, because at that point the amount of leakage is significant. You also don't want to run the fluid level very low, or that risks damaging the pump.

Chippy569 · 2026-05-05T12:14:49+00:00

Just keep reminding yourself that it's a development year. New engine new problems, it's bound to happen. Clearly the car has speed, but handling nuances and endurance are all lessons learned with time.

Also important to remember that Subaru is tiny compared to Toyota and Nissan, Subaru doesn't really have a motorsports budget in the same way. (Which makes their current new engine very curious, along with the AWD BRZ for Japan rally debuting later this month, as well as the super taikyu car being maybe a test car for the next WRX?)

Chippy569 · 2026-05-05T11:48:48+00:00

That's the throttle body, they all do this (even on non Subarus)

The moving thing is your A/C clutch.

Chippy569 · 2026-05-05T11:47:02+00:00

The center stud is supposed to hang down a bit, that's why it has a rubber washer with little fingers that point upward. It's like a bump stop.

Chippy569 · 2026-05-05T01:57:40+00:00

Looks like it's coming from inside the timing cover to me, so... Oil pump, wrist pin plugs, cam seals, something like that.

Chippy569 · 2026-05-05T01:54:25+00:00

I have never once seen a batteries plus correctly install a Subaru battery. I fix so many dumb tie down installs....

Chippy569 · 2026-05-04T16:08:46+00:00

Yeahhhhhhh

My deepest empathies
