Caravan filter dumps oil on me every time

[ruxCYtable]

I've got an 06 Caravan with the 3.3 and the filter on the bottom side. Every time I remove the filter it dumps about a half-quart of oil all over me. So this time I thought I was being real smart and I tapped a hole in the bottom of the filter with a nail and let it drain for about an hour before removing the filter. I twisted it off feeling like a genius only to have it yet again dump about a 1/2-quart of oil all over me. Why is it doing this even though I've drained the oil out of the filter?

Are you removing the oil fill cap first?
Extreme angle during draining?

When the filter is completely vertical like this (or even 45*), I loosen the filter enough to get oil flowing over the sides and drain down into a pan.

After it's slowed to a drip, I remove the filter and turn it upside-down in the drain pan.

yeah, I've done that in the past as well. I just thought I could avoid that step by draining it and walking away!

The ADBV on your filter is still holding oil in the top of the engine, that what's gushing down on you, and why the hole in the bottom of the filter didn't alleviate it.

Best solution is as posted above, put a pan under the filter and loosen it enough that oil starts to drain. Just wait for it to finish before removing the filter, but you'll still have some spillage from the filter itself, and of course by then it'll be covered in oil too.

I'm scratching my head on this one because punching the oil filter should allow all the oil above the filter to drain back. Oil enters the filter from the pump through the antidrainback valve (ADBV). It flows through the media into the center tube, and it then exits the filter through the center hole which, in this case, is pointed skyward. This would then feed oil galleries and journals above the filter.

In this configuration, the ADBV holds that oil in suspension because the head pressure of the oil above the filter wants to push the oil backwards through the filter. The ADBV doesn't let it. But if you punched a hole in the bottom of the filter, that should allow all the oil in the engine above the filter to drain out through that hole. The hole in the filter is ostensibly on the outside of the media, but the oil should be able to backflow through the media and out the hole.

The only oil that you wouldn't be able to get is oil in the supply gallery above the ADBV, but this is oil straight from the pump, and there shouldn't be a high volume of oil there.

turn the oil filter loose and let the oil run out of filter and into drain bucket. Then when ready to remove the filter, take a couple of walmart plastic bags and cover the filter, screw it off and let it drop into the bags...
Use to have same issue on Dodge 2500 with Cummins engine..

Put the drain pan directly underneath the oil filter, not yourself.

One trick is to punch a hole in the old filter, let it drain from that hole, and then remove the old filter.

I used to use Zip-Loc bags.

I do what the other users have stated already with my DGC and it works like a charm everytime. As you know it takes a while for all of the oil to drain out and down the loosened filter, just give it time.

I use a cut down plastic soda bottle for this. Works well for dodge cumins and other cars in our little fleet. No need to wait for draindown and beer stays colder..

You could go all extreme/hi tech, relocate the filter to a remote location.

Zip-Lok bag would be easier. And cheaper.

Well sure - but as we all know...sometimes BITOGers do things the more difficult and expensive way...and take pictures to show how cool it is.
