Oil Fill Cap Broke - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

congee · 10-09-2022, 01:20 PM

Hello,

While changing my oil today on my 2013 brz. The stock oem plastic oil fill cap snapped and a piece the size of a finger nail broke into the fill hole. Any suggestions and anyone know how bad this will effect the engine??

Thanks

Tough call. Would be captured by the pickup screen but might hang up in the pickup tube itself. If it doesn't come out draining the oil, drop the pan and remove it to be safe.

but then the fill opening is above one of the cam shafts. do the cams drain directly into the lower pan?

They do. That's the main reason for all the shit in the screens from the j02 recall. I could see it being chewed up on the way down, but

i'm really more curious how a hand-tightened plastic cap on a machined aluminum surface cracked enough to fall apart...

I'm betting it was over tightened and they used vice grips or something to get a hold on it

Probably crossthreaded it and magilla gorillaed it in

Very strange. Impossible to cross thread. It's like a Playskool motor skill, eye-hand coordination toy. Need the full story.

The cap was too tight so I used pliers to clamp the insides of the handle(where theres a U shaped space on each end)and after getting it off. Rested it on the opening and didn’t know one end was cracked so once i lifted it up, the piece fell right in…. Rookie mistake.

Sadly, drained the oil and nothing came out but ive driven it for around 100kms and no issues so far. Will probably change the oil again in a few days just to be safe until my mechanic is free to pull the oil pan. He did say there shouldn’t be too big of a problem bit better safe than sorry

Consider the size of the drain. When you say "fingernail," I wonder if the fragment is too big to come out the drain. Either that, or it's just laying in the bottom of the pan, minding its own business.

Hoping its just sitting at the bottom of the pan or lodge into something but it should fit through the drain hole. i suspect it’s probably somewhere in the oil fill area since theres a bunch of random gears/mechanical parts near the opening. Probably trapped inbetween something. My biggest fear is that it breaks down into smaller pieces or melts and then somehow gets through the pick up screen and filter. Going to put in new oil again and then again in a month or so just to be safe.

Meh.... Don't waste good oil.

So to clarify size, it is this piece?
