Hi,

I've done countless oil changes but today was my first for my IS350. It's been a nightmare, first when I was done I put the o-ring in the wrong place for the filter and oil exploded everywhere. I bought a new filter put it on, started it seemed fine.

Now it appears its leaking from the oil pan plug. It's just a bolt, I don't see any washer or o-ring, is there suppose to be one? I know I had a tad too much oil in my car and am draining it of the excess but it's not a lot.

Seems to only leak when I drive.

"countless oil changes" and you don't know what a drain plug gasket is and you put the o ring in the wrong spot (hint it goes where the old one was)

That's why I use a Fumoto qwik valve. No more messing with drain plug. No more tools. And no more mess or leaks

theres an oil drain plug gasket that goes around the drain bolt. CHANGE IT EVERY OIL CHANGE ON EVERY CAR

Make sure that there is only one gasket on the drain plug. If they get stacked, it may also cause leaks.

My last oil change, I had forgotten about gasket that got seized onto the oil pan... I put the gasket back onto the oil drain bolt. I ended up with stacking up the gaskets. I only found out after my most recent oil change that I goofed.

Luckily I didn't have any leaks... Sometime the gasket end stuck together or at the pan and you think it fell off into the drain bucket.

there are numerous DYI write-ups and videos on this. Next time i would suggest brushing up on your oil change technique as every car is different.

but as others have said there's a crush washer (usually sold separate from the filter kit) you need replace each oil change.

At my local Lexus dealer, they toss in a coated crush washer into each oil filter you purchase.

So yeah, you need a washer in there!
