BB, in the aldi catalogue the other week, they had an oil siphon. The terms they used from memory was that it is for 'extraction of waste oil from appliances with combustion engines'.
First time I had seen something along those lines in writing - it sums up some of their range quite well
I actually got a pneumatic oil extractor from HFT that fine as long you get the pickup hose to the bottom of the oil pan. On some engine configs it is the only way to change the oil. Briggs even have engines without drain plugs that you must use the extractor on or turn the equipment on its side to drain the oil out the fill tube. I have been using it for two now. Just gets heavy with 5 gallons of oil in it.
It much cleaner for both the equipment and my shop plus it easier to fill the recycle cans for transport. I disposed of about 55 gallons this year so far. I got another 7.5 gallons to do the first of the week.
As for the valve cover removal I have read where you take a block of wood like a 2x4. Placing the 2x4 against the side of the cover and smacking it with a heavy hammer to loosen the RTV. I haven't tried it yet, but will once I get a bad engine and if something gets damage it's no big deal.
Just something I have read.
