Dumb question here, but is it possible to go in through the oil fill port (on a 4cyl) to vacuum siphon out about a half qt. of oil?
I had over-filled when I did my last oil change. (IMG:style_emoticons/default/headbang.gif) I didn't want to pull out the quick jacks and pull the drain plug unless I had to. TIA |

TIA That is a 8mm OD tube so sucking oil tube so sucking oil through it may not be easy. You could change oil filters and that will take out about 1/2 quart. @drem914 |

My car does this on its own, just park it on the cleanest driveway you can find. Bonus is that it's also self-lubricating.

I had a pump that sucked oil out on my boat years back. Dunno if there's a direct path to a low point on a 914 sump/pan though?

If you are looking at the dipstick indicator, a half a quart over full in a 914-4 is not a bad thing. It will keep the pump from sucking air on hard turns. We have run 914s that way for years with no issues.

Clay (IMG:style_emoticons/default/agree.gif) 100% I have another mark on my dipstick that is the same distance above the top mark as the factory low mark. That is where I measure mine cold. If you still feel the need to to remove oil you can use a Mityvac in the dipstick tube. |

Gotta say, I don’t have any half filled quarts of oil.
I get close, I pour till the quart is empty I bit extra on an oil cooled motor is all good |

An extra half quart will not hurt anything.
I intentionally fill mine about that much extra for racing to avoid the oil pump sucking air under hard cornering. |

Well I didn't have to do any of that, just ran the engine real hard over the weekend with a hour long 80+mph run on the freeway as a precursor to a couple hours of mountain driving with lots of curves and then a long freeway drive back. Will have to see where it went since I am not getting any visible drips below.
