Changing oil...Let it drain overnight ?

Pre fill the Filter ??....I am not so sure why given all the potential mess involved......


I have found that Camshaft bearings and rod bearings maintain oil for a very long time with engine not running (like years).
The Lifters also maintain oil on their surfaces for a very long time as do the Cams.

Likewise the Chain Guides maintain oil for a very long time. The Chain tensioners will bleed back oil but it has been said that Start Up Loose Chain guide slap is just a noise and no harm and no foul mechanically. Having said all that......pre-filling the filter definitely does not hurt the engine in any way

But - but - but...Thar ain't no PRESSURE on that residual oil, doanchaknow! Not filling the filter means it takes longer before the pressure comes up, an deez dern 1990s rev to 1800+ on fire-up and hold for a couple seconds before idle slows down to settling. The sooner I see pressure, the better, at least that's how I feel.

Yep.....you are correct on those start up revs for sure......and concur on seeing the oil pressure build up as quick as I can.

So, do some filters let you pre-fill with oil, turn them upside down and the oil doesn't pour out (all the time while you're spinning it in place)?

Yesterday I bought a Napa Wix 1324 filter and will be changing my oil this week. It's hard to imagine not making a mess.

I've always prefilled oil filters in the past, but I've never had a car with the OF on top of the engine upside down.

The best way to install a pre oil filled filter for the LT5 is to turn the car upside down, that way you won't spill a drop....I'll just leave it at that.....

I could see just pouring enough oil into a new filter to saturate the filter media which might facilitate a quicker flow-thru when the flow of oil fills the empty filter can on start up. You could reasonably expect to be able to flip it and screw it on quick enough to not make a mess.

Plus if do it fast it will be a centrifuge of sorts and won't blurp out the threaded hole. Don't slip!

Maybe there is a worthwhile market for LT5 oil change bib - you know, like the bibs they hand out when you go to eat crabs - anti-blurp bibs?!

You guys.

That's all I do. I fill it about halfway up and set it to the side. Within minutes the filter media soaks most of it up.

That's what happens. Flip it over fast enough and you won't spill any oil. You can just spin it on quick enough.
