Oil leak above filter and pan

[team_goose]

I noticed a leak above the filter and pan after pulling off the cover. Any idea where this leak might be coming from? There is a hole there where it drips through almost like it was designed for that.

Actually looking a bit closer in the daylight I can see this is coming from the top 3 bolts that were in another thread. So if you see this that is most likely your cause! Off to the dealer it goes.

Keep us updated on what they find. Might need to replace the gasket behind those 3 bolts. How many miles does your car have now?

Assuming thats what it will be. Right at 49k, and took video of the bolts so there is no you tampered with them story.

So dealer said its not under the powertrain warranty which is 3yr/36k. I have an extended warranty purchased from Kia from Zurich that is 10yr/100k that I asked about and he said it wasn't covered for it. I think he thought maybe Kia's 10yr warranty and not the extended. I would think they would look for that when bringing a vehicle in. While the deductible is 100.00 it would be worth it to replace the whole unit for that price but they are claiming its just the gasket only. So I am not paying a 100.00 if it were covered for an 8 dollar part. I will just order a new one.

Is it the oil filter housing?

Is it the oil filter housing?

Without having eyes on it myself, this is also my thought.

 

[Senator20]

The oil filter housing should be under warranty if your under the yr and mileage. If not it is easy to change out yourself. Mine leaked when it was really cold outside. In the warmer months no leak.

Did you replace it yourself or under warranty? The reason I asked is because I see that Amazon sells the filter housing but in aluminum I believe. The plastic housing is easy to over tighten and causes a leak or it can also be the gasket.

I replaced my leaking plastic one on my '20 with the aluminum one. I have a lift so it was pretty easy - Less than 1/2 hour.

Under warranty.

They claim its the gasket and as I pointed out to them it is cheaper for me to just replace the whole housing and be done with it. Just waiting for the new one to be here today.

That should be covered under warranty.

They told me its not because its the gasket on the filter housing blah blah blah. My extended will cover it but its 100 for the deductible and I ordered a new one for 55 and it will take like 15 minutes to replace so I just said screw it so I didn't have to wait for them to figure it all out. Still BS I agree but its typical from this dealer it appears. Folsom Lake Kia just FYI in Sacramento.

I had mine replaced under warranty. I hate when dealerships try to take advantage of customers.

FYI:

Modern oil filter housing seals (called a gasket, although no longer an old school paper gasket) do leak. It's a twofold process:

The seal looses it's ductility (gets hard and brittle) and also shrinks. Oil gets past. Most usually during the "warm up" phase of engine operation.
ALSO the oil filter housing (made of a nylon composite, often called "plastic") is NO LONGER flat. One warped surface; the housing, one flat surface; engine block, and the aforementioned compromised seal and Viola' we have an oil leak!

It's NOT rocket science. Just about all of the MFR's now use a "bolt on" oil filter housing. This gives them a LOT of flexibility.
Want the engine in a North/South configuration with rear wheel drive, use housing XX. Want it in a LHD small Ute (steering rack in the way?) use housing BB. Want it in a N. American FWD platform, use housing ZZ. You get the idea.

Toyotas, BMW's, VW's and MANY others have oil filter housing leaks. Owing the the reasons I stated above. Almost all of them are fixed the longest period with a NEW housing and seal. Flat to flat works. A new seal inside a warped housing, will only last a short period of time.

(P.S. We used to take the BMW aluminum ones and pass them over fine sanding cloth and a surface plate to flatten them back out again. Once they switched out to nylon, we only installed new. Over-tightening is NOT recommended. Further distorts the housing, potential of stripping the threads on the engine block.
NEVER use any sealant in this area!!
It's a direct path to the oil pump and/or the main oil galley.

Ever see that squished out silicone on the outside of installed parts? Of course you have.
Guess what, there's an equal amount on the inside.
It gets very hot in there. Sometimes pieces become pliable and break off. This migrates around the oiling system and clogs oil squirters, bearing feed holes and more.

This was a great write up and while I suppose some of those thoughts came to mind it really did lay it all out perfectly! I do my own oil changes and this definitely could have been self inflicted! I will take a picture of the gasket and post just out of curiosity for all to see. Appreciate the well written response.

Not your fault. Same thing happened to me

i did the same (comparison of old vs new gasket photos in my post at the below link)...i didn't want to take a chance in case the existing housing was cracked...now i have 2 housings and next time i will just order the gasket only...i wouldn't order the aluminum version as i don't want it to affect the warranty and the aluminum one is not going to prevent the leaking as it still has the same gasket...you can't tighten the plastic one any tighter to compress the gasket due to the metal bolt sleeves (so you don't crack it)...it would essentially be the same with the aluminum one

Post in thread 'Oil Filter Housing'

Mar 25, 2024

Here is the problem with this plastic oil filter housing abomination of engineering…2022 with 41k miles leaking all over the place…you can see what the gaskets look like on the old vs the new housing…next time I’ll be swapping out the gasket only…the problem is the bolt sleeves won’t let you compress the gasket any extra and the bolts are only torqued to 15 ft*lbs…on top of that I opened up the new one once it was mounted to put some oil on the housing cap gasket then I torqued it back to I’d say 34.5N*m and you can see that it’s tighter than how it was shipped looking at the white marks...
