messy 496HO spin on oil filter change
Suggestions/tricks to use when changing the upside down mounted spin on 496HO oil filter to prevent oil spillage?

Poke a hole in it with a screw driver and let the oil drain to the pan.

Is there any wrong place to punch the hole that for example would release the collected filtered out 'dirt' back into the engine? |
Re: messy 496HO spin on oil filter change
Not Sure. The dirt should be trapped in the filter material. Dead center so it doesn't run over the side. I relocated mine so it sets right side up.

Has been discussed before:
http://www.offshoreonly.com/forums/s...er+screwdriver Take a screwdriver that has a square shank about 3/8 in diameter, and pop a hole in the very top center of the filter with a hammer. Let the screwdriver insert a couple inches, but not far enough to extend out the bottom of the filter. Let the filter drain into the pain for about 20-30 minutes before you remove it. You will not spill a drop; guaranteed... as the filter will be empty. I have a specific screwdriver that I cut and sharpened for this task. It works like a charm. I'd actually RATHER have my filters inverted now; using this method. With the filter mouth pointing up, as soon as you loosen the seal, oil is going to spill out of the cavity above the filter, and run down your filter into your bilge. By draining as described above; I don't spill a drop. |

Similar result- different technique, I just loosen the filter- once the initial CCW movement occurs I turn it slowly until the o-ring seal just barely breaks- you can see it and hear it- air will suck through but the oil, beingh thicker will nto weep through- works like a charm- I just start draining afterwards and by the yime I'm done the filter is empty.
good luck! |

Another option. Very good. Thanks.
What about filters with an anti drain back feature? |
Re: messy 496HO spin on oil filter change
Punching a hole in the filter (TDC) is the way to go... BUT... last week, after changing oil, one engine did not develop enough oil preassure. A piece of the filter (I asume from punching the hole) had fallen and was resticting oil flow.
Just make sure everything is clean and clear. I think this was a freak deal but it happened just the same. |
Re: messy 496HO spin on oil filter change
I use the Napa Wix Racing 1060R filters on my 496HOs, and they drain down completely dry once I punch the hole EXACTLY top dead center.
My 'special' screwdriver has the 3/8" square shaft. I filed the tip down to a very sharp point, so it will pierce anything that it goes through. I also was sure to find a screwdriver that is the exact length (actually 1/2 shorter) than the height of the oil filter itself. That way I know it won't exit the bottom of the filter and damage the housing on the way down. |

Anyone?

Re: messy 496HO spin on oil filter change
I've always just pierced the outer shell, I never drive the screwdriver in. Once the vacum is broken, the oil drains right out. I usually do it the night before I change my oil, and the next morning, spin it right off without any mess.

OK, thanks!
