Filling up new oil filter prior to installation

In theory yes, but in practice on the engines whose oil I have changed, my observation is:

- Remove the filter shortly after shutdown and oil gushes out from the engine.

- Remove the filter after the engine has been off for 12+ hours and no oil flows out.

My conclusion is that the ADBV slows down the reverse flow after shutdown, preventing sudden backflow, and apparently that is all the manufacturers expect of it. Gravity eventually draws down most of the oil above sump level.

The caveat was "if the ADBV is working correctly". Of course, some work better than others.

If you read the thread I linked in my previous post, you'd see that the PureOne (with silicone ADBV) I tested sat for a whole week with the base down and no oil that was trapped between the center tube and outside can leaked out - even with the center tube open to that atmosphere. I would expect the same result if that filter was on the car. That ADBV sealed 100%, and gravity didn't cause it to leak while sitting for a whole week with the base down.

I try to do this on a vertically-mounted filter.

The filter on my Ford is sideways too. I find if I fill it before I get under the car, by the time I am ready to install it, the media absorbed almost all of the oil. At least enough where I can spin it on and have maybe a drip or two. It still cuts out the dry start nastiness.

I was surprised after a recent OC that the P1 filter (pl14610) was empty after sitting on the oil drain pan ledge (designed to hold filters base down) when I went to empty the oil pan. Usually I find I need to push the ADBV open to get the last of the oil to drain out. I will have to be sure to inspect this filter once cut open, to look for tears.

Maybe a good practice is to check oil levels shortly after engine turn off and then again after sitting all night. If there is a difference indicating oil drain back and not typical for the engine, then time for an immediate filter replacement.

^^^ Could be there is something wrong with that ADBV ... possible tear like we have seen reported by a few here lately. Let us know what you find.

I always pre-fill my filters. I like watching the media absorb all that clean new oil.

The 396 and 427 were introduced late in the 1965 model year for the Impala and Caprice, along with the Turbo 400 trans available with only these engines. Actually the Caprice was introduced about the same time. I doubt if there is such a thing as a Caprice with a 409. Maybe somebody knows for sure.

Edit: Actually available in all full size Chevys. I think there are some 2-door Biscayne 427 drag cars still running around.

It's not a Caprice but it's an Implala with a 409.

And, some Biscaynes.

I have Chevy Orange running through my veins and found this link very interesting.

But, I will still keep looking for a factory 409 Caprice.

I saw on internet a guy who changed his fram ultra xg2 somewhere around 4000miles and when he did he noticed the filter inside was moving all around and rattling. That was scary considering it was the same filter I just put on my f250 a 1000 miles ago. Ive never seen that happen before. Also someone said that if you prefill the filter it would help with that problem. I always prefill the one in my car but I never did it on my pickup because of the sideways mount. I guess from now on ill fill the filter up halfway and put it on as fast as I can. I know cat years ago said to never prefill but a few years back they said to always prefill. Not sure how they feel now.

I have been changing my own oil since about 1964 and have never bothered with pre-filling a filter.

 

[Errtt]

I always fill, and if the filter is side mount like on my Harley, I'll try to get over 1/2 fill then spin on as fast as I can.

I do this as well though after years of doing it, I've gotten to the point that I can fill pretty close to as much as it can without spilling out if I go SLOW. On some cars, its harder as it has to navigate around things in the way. I don't know how many (virgin) oil baths I've taken.

 

[Black_Thunder]

its one of those sometimes i do sometimes i don't kinda things.




at work when i change the oil on semi's if they have a spin i try to fill the filters at least halfway. most trucks now have the cartidge filters on the sides of the engines and those do not get prefilled, so i would imagine the manufacturers would say its not necessary, but do what makes you feel good i say.
