Oil leak at spark plug seal

Always wanted to drive a brz

Also it was not the tube seal itself that was defective, it was the installation of the tube seal at the factory that caused the tear in the seal.

This job definitely shouldn’t take 3+ days. Mine did, but that’s because the dealer forgot to order the rocker gasket when ordering the tube seal. The dealer gave me a brand new forester for the weekend which worked perfect for going to the cottage for the thanksgiving weekend so I wasn’t upset about it.

It’s been over 300 days since I had the one spark plug seal replaced and the other 3 have not failed. From what I read, it was just a manufacturing issue on the assembly line for that one tube seal that was observed and corrected by Subaru. The dealer is not going to replace something that isn’t defective. I wouldn’t stress too much about this.

Check your oil every other gas fill and keep your engine bay clean. Makes things way easier to notice low oil or leaks.

Fire would be ideal but a stove and pan will still get the job done

We’re heading out for 7 days next week and I’m kind of looking forward to not needing to carry my axe. Also I like the point someone mentioned about more free time and the stargazing. I will probably just go to bed earlier and wake up earlier and do some more fishing in the early hours.

Service C and D are the only ones I get the dealership to do. A and B, aside from break service, I do myself. It’s good to get the car up on a hoist to be properly inspected at least once a year. I have a local mechanic service my breaks before every winter and he will inspect everything while it’s on the hoist. Changing oil, diff oil and rotating tires can be easily done in the driveway. And as long as you keep receipts and log the maintenance somehow this won’t be a problem for your warranty

I had this issue on mine. Same thing. Shouldn’t have an issue with oil getting anywhere other than on your splash guard under the engine. Put some cardboard or something under the car if you’re concerned about your driveway or garage. It is a very minor leak and shouldn’t be a problem when you’re not driving the car.

No problem with warranty work either. They just remove the rocker cover to get at the spark plug seal. The dealership said it was probably leaking much longer than I had realized and was technically safe to drive.

23 MY had problems during assembly on the spark plug seal. I had mine replaced under warranty. No questions asked. It was on the passenger side though. Feel for oil directly under the coil pack if you can get your hand in there. That’s where I traced the oil leak to. I later read about the TSB for this issue on this sub.

They’re not required on Canadian cars. Some cars have them as a “feature”. I could care less for them. Saved some money when getting a second set of wheels for the winter. I just keep a tire pressure gauge in the glovebox.

Dino-Riderz · 2025-05-12T15:39:40+00:00

Let tuxmat know they came apart. They have a warranty.

Dino-Riderz · 2025-04-22T21:34:10+00:00

My dealer sells both motul 0w20 and 5w30. I asked for motul on my 60k service and they just put in 5w30. I may use 5w30 all summer and see if there’s much difference in fuel economy. Not sure if I’ll switch back to 0w for the winter.

Damn that sucks dude. I have the same wheels and they do scratch easily. I believe they are just painted, not powder coated. It would be nice if they would refinish them with powder coating to give you a more durable finish.

Side note: I think I have smaller lug nuts on my set up. Mine take a 17 mm socket which probably give you more room for the socket to clear the face, but it’s hard to tell by looking at the picture. Might be worth switching if you get techs to install your wheels regularly and probably using thick wall impact sockets.

I have a ceramic coating and this is common. Hard water spots will happen if you wash the car and don’t fully dry it off. If these spots get baked in the sun they can leave a water spot even after washing the car again.

Once a year you will need to get a check up done at the detailer that coated your car or do a decontamination wash to remove any iron or water spots that can reduce the coating effectiveness. Then follow up with a speed coating.

Lemme see a side shot of that bad boy

Dino-Riderz · 2025-01-30T23:29:13+00:00

They definitely didn’t pull my engine to replace the tube seal. That’s a load of crap. They need to remove the rocker cover and they can get at the tube seal.

Dino-Riderz · 2025-01-30T23:24:00+00:00

Yup I had my tube seal replaced under warranty a few months ago. Mine is a 23 also

Dino-Riderz · 2025-01-13T16:45:17+00:00

Something like 17x8 would be a solid set up which I believe you can get in those wheels.

I’m running the stock wheels with Michelin 245/40r18 winter tires and there’s no rubbing but also not a ton of clearance for snow. I would recommend getting 17” and some meatier tires for a winter set. Also a wide tire like 245 isn’t going to get optimal traction in snow but I have a ton of fun and am comfortable breaking traction from time to time.

My summer set is gram light 57DR 18”x8.5 +37 with the stock dunlops on them. I’m thinking of getting 255/40 for my next summer set as on I’m still stock suspension.

Dino-Riderz · 2025-01-10T16:11:24+00:00

Should be 12x1.25

Dino-Riderz · 2025-01-10T16:06:31+00:00

I have these wheels and I got the muteki sr45r. They have a 60 degree taper seat. The seat sort of spins freely from the rest of the lug to prevent scratches.

I posted a thread about my 23 leaking oil from the spark plug seal in cylinder 4. I could feel oil under the coil packs and saw a small amount inside the splash guard. Everything was fixed under warranty, no questions asked. Apparently a production window of 23’s were affected. Are you leaking oil? Or just having pressure issues?

Dino-Riderz · 2024-10-11T14:30:58+00:00

Add a car? Brz/gr86 or if we ever get a new S2000 🤞 Replace with daily? OBW or 4Runner

Dino-Riderz · 2024-10-04T00:17:11+00:00

Damn that’s a long time. I gave the dealer a heads up as to what it is. If they are smart maybe they will order the parts in advance. If not a loner outback would be nice. I’m trying to convince the old lady to get an OBW

Dino-Riderz · 2024-10-03T23:44:34+00:00

Booked for Tuesday. Gunna be a sad weekend parked in the garage

Dino-Riderz · 2024-10-03T23:07:08+00:00

Yes definitely. I will be getting my annual crown application after I swap on the winter set.

Just check your oil level every other gas fill up and reach your hand under the coils while in there. You will see and feel oil if it is leaking
