Bad WTF

[Harshman]

Got the oil changed in April at local Kia dealer. Recently noticed an oil puddle in garage. Level was a bit low. Took it in to have it checked and am told that an aftermarket drain plug was the cause. Gasket wouldn't seal. They replaced it. I can only wonder where the plug came from.

have you always changed oil at kia?

First one was Jiffy and did one at a Mazda dealer 2 yrs ago. Got 37k on the car. Seems odd to appear this delayed.

well, you answered your own question, one of those used the aftermarket plug. and yes, it took this long to get compromised with a dried out gasket, so that kia tightening it cracked it through no fault of theirs. glad you didn't suffer a catastrophic leak on a road trip or something like that. the question remains, though, why the oem drain plug went missing. Ima guessing that the moron doing your oil change lost it and they fetched a replacement.

Always replace the drain plug washer with every oil change (it comes with the filter).

Glad I do my own oil change.

How does aluminum dry out?

I've never seen an oil pan drain gasket made out of a non metal material. Infiniti/Nissans used a weird copper washer that would visibly compress when tightened. Honda used an aluminum washer as does the stinger.

Keep in mind the OP did say the first oil change was at Jiffy (we call it Goofy) Lube, then Mazda. I can attest I have seen Goofy Lube use crappy plastic washers in place of proper drain plug gaskets/seals. If the later techs who did the oil changes were lazy (because all techs that do oil changes are top notch right?) chances are they could have even re-used what they found.

this is why I come here, to learn things. so, not 'dried out' but deformed? or dirty? anyway, reused, as pointed out by other posts. I knew there was a seal on the drain plug. the last time I changed oil myself was when I owned a VW Bug and I didn't ever put in a new gasket / seal, which is probably why I had to add oil as often as I did. the bottom of my engine was always oily and I just took it as 'normal operation.' the op had a crappy kia oil change, that's inarguable. because they should have caught the reused gasket and replaced it new. blaming it on 'aftermerket' was just slithering out from under blame.

The plug looked to be brass. I assumed that the gasket would be changed each time. We all know what they say about assuming. I labeled it 'bad' because the other choices did not actually fit. The dealer did replace the plug, gasket, and lost oil at NO cost to me. Seems to me it is actually a wash considering all of the factors.

Seems like changing the washer is a no brainer given the kit (from kia) comes with the washer and all necessary orings.

Over here it is very common to change both plug and gasket with every oil change. They are so cheap…

Brass huh? I wonder if your car had a Fumoto valve?

No valve, just the plug.
