Oil has been extracted from boat engines through the dipstick for years. You can get an inexpensive pump from a boat place cheaper than the one in Griots.

After the dealer overfilled the "Z" engine with oil, I also had the idea of just siphoning it out as I do on my boat. However, when I tried to run the siphon tube down the dipstick it would go only so far and would not reach the oil pan. I thought maybe a crankshaft journal was blocking it from going all the way in and I started the engine a few times and still no luck.
I have no idea what the obstruction is but you might want to check your's and see before you spend the $.

No, I did not read the fine print. I was quickly posted it up there for review. Makes sense, you wonder how effective a pump would be on these models, due to the internal channeling in the pans. Seems like these baffles would make it hard to remove the oil by this method.
This may also make it diffcult for any of these others tpyes of pumps to potentially work, unless you can park the car in such a way to get all the oil to drain into the dip stick side of the pan.
Here is the scoop I got from a local respected Corvette tech who works at a nearby dealer, Pohanka Chevy: The dip stick tube has no obstruction or the dip stick would not work. However, the tube narrows at the bottom to where it is just large enough for the tip of the dip stick to pass through. Hence the problems people have reading their oil level. So, if your extraction tube is too large, it won't fit. I believe the one I bought may be OK. If not, I will rig up some "drip tubing" and try that. That is drip tubing as in drip-watering plants, etc.. I will report progress on this most important project.
The continuing saga of the dip stick extraction pump.
I got my nifty marine supply house pump home and the 1/4 " OD tube would not go far enough into the dip stick tube. So, off I go in search of a smaller tube. After visiting Home Depot, Lowes, a nursery, I finally located some 1/8 " OD flexible tubing and a couple of fittings that seemed to be the right size. Got it home and all assembled and attempted to extract some oil. Well one of the connections was sucking air, but I kept pumping. After about 10 minutes a few drops dripped into the container. After about 1/2 cup was extracted in 20 minutes, Mobil 1 5w-30 began leaking out of every seem in the hand pump. Everything, including my hands had a light coating of oil on them by then. I decided to try another method another day and threw the whole thing into a large plastic garbage bag. I may change my mind, but I believe it will probably stay there.
I'm considering ordering one of those Harbor Freight jacks and learn how to jack the car.
You aren't going to get all the oil out of the dipstick hole. If I was worried about changing the oil, I would get a set of rhino ramps or use a couple of boards so I could get the car up high enough to jack. But, thats just me....
I'm taking my car to the track in a couple weeks. I read the warning about putting an extra qt in. This thread is about getting oil out-is it that important? In-other-words, are you going to trash the engine running an extra qt for a few thousand miles until the next oil change?
