Oil Drain Plug O-Ring...
 

So I did my first oil change today after 5 years of owning the car...:wiggle:

BUT when i'm done and set the car back down, I found out I left out the drain plug o ring... Drove around for some time and went home, nothing's leaking or what not... Should I be worried about not putting it back for now? To my understanding the o ring just helps for better sealing, right?

I mean there's really no way to put the thing back without well doing another oil change right? hmmmm

Check it again after a tank of gas .... if it still isn't leaking - it isn't going to .

It's doable ... but messy .

if I were u, I will just get a clean milk jug (or distilled water jug) , catch all the oil and put the o ring back on

even if I have to change the oil again, couple qts of oil is still cheaper than an engine, just knock urself in the head and remember it next time :)

if its not leaking, its fine.

the washer is 9956-21-400 or 9956-41-400. one number is aluminum and one is copper, the copper one is $$$

If it isn't leaking it should be OK....buy a new one for next time. ( Think they are about $1 )

Look under the car every once in a while and check it isn't leaking

Drain the oil and put a fresh one.
At least u did an oil flush once in a while.
Washer were used for purpose right?
And put a new one. Don't re use it.

Or if u dont mind checking under the car like dannobre posted,
Then leave it.

Yea, I'm checking the car everytime i leave it so. I don't drive it very often, so I guess I'll wait for 3 months then.

Haven't had one for 10k miles, no leaks. I keep meaning to get a few and use them but I forget about it until its too late. They are a good idea to help prevent stripping the pan/bolt but it is not needed to prevent a leak.

Just use a crush washer from an old spark plug. Same size.

Fumoto Valve FTW.

I need one of those. Have they ever failed though?

No… had one installed 2 years ago and it's still working like new! I'll just plug a tube on it and drain the oil in a pan 3 feet from the car…then close it an refill after changing the oil filter no need for a jack… :)
