Yes, you change the oil through your dip stick. You can buy the tool just about anywhere, West Marine, heck, I think I've seen it at Walmart. But, if your inventive like me, you'll take a shop vac, get a piece of hard tubing so it doesn't collapse, then use your shop vac to remove the oil. You'll need to put water in the vac, and I probably shouldn't be telling you this, since oil can put off a vapor that can explode in the electrical part of your vac. I'd done it taking oil from my rotary chamber of my 787,
The oil filter, much easier to get too... I'll attach a pix, maybe you can spot it easier that way. And make sure, you use the proper oil. Using the wrong oil has caused me to rebuild engines that I wasn't happy about, after telling them not to use TCW-3. Not sure what your 4-TEC calls for, but make sure, you get the right stuff.
I'm attaching the pix now.. Good luck!
