    Get more oil out during oil change.

    So I don't really like the idea of cranking the engine over after sucking almost all the oil out. While there should be enough residue on the bearings the crank is surely not "floating" on oil. I had to replace a head gasket on a 155hp GTX today. I noticed I could see straight down by the timing chain into a puddle of milkshake from the blown gasket.....this gt me thinking............

    So I grabbed a bit and a 1/8" pipe thread tap. And drilled a hole through the rocker cover right in between a couple ribs.

    Then I marked my siphon hose with tape at the top of the dipstick tube and started changing the milky oil. Got a little over 3 qts out. Each line on that siphon ball is a quart.

    Next I put the tube straight down the newly drilled and tapped hole. I had to wiggle it just a bit "feeling" my way down til it stopped and my tape was about the same place as in the dipstick tube. As you can see in the ball I got out another 3/4 a quart. I repeated this 3 times until the oil was not milky anymore and I got between 1/2 and 3/4 of a quart every time! Then just wrapped the pipe plug with a bit of teflon tape and threaded it in snug.

    Now every oil change will get almost ALL the oil with no extra cranking.

    I have always had pretty good luck at pulling the lanyard at 3-4000 rpm to get more oil out of the sump. That way I don't have to mess with turning it over two of three times to get additional oil out.

    Cranking the engine over for 10 seconds to get out residual oil will do no harm at all to your engine. Also leaving some old oil is not an issue either most people change their oil at less than the recommended 100 hrs anyway. . Most Automobile engines leave 1 liter of old oil in the engine at drain time.

    It takes at least 3 changes to clean up the oil in a water flooded motor. If removing the cover, and tapping a hole in it makes it easier, it’s a great idea. He’s not talking about for a standard oil change, he’s talking about a way to remove more milkey oil from a flooded motor. Genius.

    Yes, since I had to change it several times, and had the cover off anyway..........
