I measured the thickness of the sump where the plug goes, it's about 8mm or so.





Measuring the threaded portion of a Fumoto drain valve, it's within 1mm or so of that so no issues with not getting a full drain at oil change time.






It was either this valve, that allowed the spout to be placed in any direction, or the simple one, that just exits in the same direction as the original sump plug did - both have about the same extension from the sump, and this one is a little nicer, allowing a tube to be fitted so i can drain straight into the waste containers instead of using a drain pan as an intermediary. The pictures make it look very large for some reason, it's probably only a little larger than twice that of the factory bolt, so not bad, plus it's a lot higher than the anti-roll bar and the engine cross member.

 

Just out of curiosity, as i changed the oil earlier than my intended 5000 miles, i checked the IOLM for % left (i had set it to 50% on the last oil change so the max it should give me is 5000 miles, or i *think* 6 months, not sure on that though - default on the system if reset to 100% at oil change would be 10000 miles max, or 1 year max)
The truck read 12% left on the oil, that calculates as only 600 miles left instead of the 1200 miles it would take to get to 5000.

At 3800 miles, that would leave 24% left on the oil based on a 5000 max, but it does know i've been towing and it does know idle times and how hard it's been driven (hard towing, WOT & up hills towing etc.) and the overall time since the last change/monitor reset is a little over 4 months, which in time would be 75% of the 6 months total.

Nothing riveting there, but i did think it was interesting it only gave me a predicted 88% of the oils life.

 

Now you've got me thinking about a separator. With a high mileage engine that's likely to have a little more blowby than when new, it seems like it would only help longevity and performance.

 

Same, you're a big help at spending my monies.

 

Yeah, it's not a good thing for our wallets on these forums

And yes, our higher mileage engines will likely have more blow-by - it will be good for the engines as it will keep the mixture cleaner, it technically has the potential to save a little fuel, but i'm more in it for the cleaner, more efficient (powerful) burn.

 

Love the fumoto! I see you got both styles. Was that to check what would work best? I considered that adjustable style and to be honest, I almost kicked myself in the butt for it. I almost couldn't turn the plug because the neck was just starting to hit the oil pan as it got close to being bottomed out.

 

Yes, exactly that.

I figured that i'd end up with something stupid, like the tap rotated to the bottom or such like, so went with the adjustable version just in case, particularly as there is a ton of room down there. Having said that, i saw the same issue you did, right as it got close to cinching down, it seems the sump is not symmetrically shaped on either side of the drain hole.

 

My pan has this radius in it, for whatever reason. When the top of the valve came around it barely scraped it. For a moment I thought I was screwed because I wasn't going to force it.

 

Oh yeah, the 3.5 pan is much nicer for getting all the oil out with that dip, but that radius recess will certainly make you question the clearance

The 5.0 pan isn't as sophisticated, as you can see from the pics and likely remember from your '18(?) - It tilts back in the chassis, i checked that with a level as i was curious, so with a lift/level on the suspension it will assist draining further - all assuming drained on the ground instead of ramps or elevating the front.
You'll be glad to know, if you didn't already notice, that regardless of how far in the threads of the Fumoto go, your pan design means it'll change nothing, it's got more chance of doing so on mine, hence why i measured it.

 

I do remember that tilt on my 18. The 3.5 is way different. When I 1st saw the pic of you checking the depth I couldn't understand why. They I read a little more and it all came back.
