Hello,

I need to do an oil change coming up for my 18 Ram again and the last time I went through the wheel well for the filter. I had an issue getting the filter lined up to get it on as you can't see the threads and was wondering about going through the top this time, but not sure if comfortable taking off the air box tube that goes into the turbo as I don't want an issues with something getting in turbo. What have you found to be the best way to change the oil - any feedback or tips are appreciated.

Thanks,

Mark

You are overly worried. You wont get anything in the turbo.

Remove the air box cover, disconnect the elbow going from the box to the section of tube going to the turbo. that alone should give you enough room. If not just disconnect the few plugs and pull the whole airbox. It ads maybe 10min total (remove and reinstall) to the whole process.

My opinion may not matter as I've only done one oil change on my truck but it seems like a lot of work to remove the air box just to change the oil filter. The time taken removing the box could be more than it would take to align the filter.

But if you are set on removing the air box and are scared of something getting into the turbo could also put a rag in the turbo inlet to make sure nothing gets through.

I never take any part of the air box loose or off when I pull the intake tract out. Just loosen the clamps at the top where the elbow attaches to the air box, and the one at the bottom where the elbow attaches to the turbo. Then there is a spring clamp for the crankcase vent tube, squeeze it with pliers and slip it down the hose, then twist the hose to loosen it and slide it off, then the whole intake tract tube/muffler assembly pulls right out.

I use a 1/4 ratchet and extension and a 10mm deep socket to loosen the clamps, and a pair of slip joint pliers for the spring clamp.

You will then have LOTS of room to R&R the oil filter, and all you have to do is just check the turbo inlet for debris(never had any in mine) before re-assembly.

And, it only takes a few minutes to R&R the intake tract.

They make plenty of filter tools that screw on the filter so that you can do it through the wheel well without spilling oil - go on Ebay and search "6.7L cummins oil filter tool" get one for about $20

I just found out about that tool yesterday. Seems really helpful but not really necessary.

Been doing it through the wheel well since the first change. Probably 12x now. No issues. Too easy. Why take off parts that you don't need to?:confused013: At the end of the day, either way gets the job done.:thumbsup:

Yep, pick your poison. I chose to remove the intake ducting. While I have only done a few changes thus far, I do not mind it and probably will not deviate from it.

I am also the guy that likes to inspect the truck as I work on it. The more I get my hands on, the more I can check things out.

On my 2 changes I went through the wheel well and have that spill proof tool but its very hard to get the filter past the cooling lines I think next change I will try removing the tube.
You do not even need that tool. Use a ZIPLOCK bag. Using a filter wrench loosen the old filter slightly so you can now spin it off by hand. STOP. Take filter wrench off and slide ziplock bag up over filter. Spin it so it drops in the ziplock. Close ziplock and pull out. If you have OCD condition like me and need to fill some oil in new filter just reverse the procedure using a second zip lock.

I beg to differ. I used a ziplock the first few times. I snagged it on the way out the last time and got oil all over the place. I then bought the screw-on cap.

I have no problem going through the wheelwell except I don't much care for pushing a clean filter up into a spot I cannot see. Every time I do it I think there could be some debris/dirt that gets knocked off of something and it falls into the filter unknown and unseen.

You don't need a bag or any filter cap, or any special tools when you go through the top. No reaching through some hole in the fenderwell, that on auto trans trucks is partially blocked by the cooler lines.

But, as I have stated before, to each his own.

I, personally, find it much easier, cleaner, easier to see what I'm doing, by going through the top.

Ditto! Pick your poison! The "easier" way is just a matter of personal preference.

Helped a friend do it from the "top" one time. I prefer the wheel well--for me it's just less hassle. I just sit on a small garage stool for the entire oil filter R&R. 5-minutes and I'm done. No high altitude nose-bleeds from having to climb up high on top of the engine--lol!

If you choose the wheel well method, highly recommend investing in a filter plug to guarantee yourself zero drama for each and every oil filter change. Check out the plastic Lisle 57180 filter plugs. They're cheaper than the aluminum versions and work just fine. Yes, you can use zip lock bags if your tranny lines aren't too close together. However, if your tranny lines are especially close, they will tear those zip lock bags (even when they're double bagged). When they tear you will have one hell of a mess on your hands.

I'm 6'1 and have, as some would say, long ganglion arms, not caveman like but close. With a stool I can hover over top the engine bay and have easy access to R&R the filter. Now it wasn't until the 3rd change that I actually made a mess under the hood. Bumped the half full filter when bringing it under the hood. Oil everywhere. Did what I thought was a good job draining the front filter. Not the case, popped the filter out and fuel all over the damn place. Good help is hard to find these days...

If you look at the filter installed through the wheel well you will see it has a slant. The bottom of the filter tilts forward towards the bumper/radiator. The first time i tried to go through the wheel well i could not get the filter started. Once i realized it had a slant i can hit the threads perfectly every time, even blindly.
I also found that on my past 14 and current 15 i can slip the filter through the opening real easily if the base goes in the cutout first and has an upwards slant. Slips right in easily then i rotate it to the platform below to remove the Genos tool.
I have never worried about any dirt getting in the filter. By the time it gets installed i have cleaned the base and all around everything i can touch. It helps to keep the engine bay clean as well. If you don’t clean the motor you do not love your truck.

"there is a spring clamp for the crankcase vent tube, squeeze it with pliers and slip it down the hose"

On my 2016, the spring clamp for the crankcase vent tube had rubber molded around it and could not be moved without cutting the rubber away first.

Sorry, forgot about that, first thing I did when I took it off the first time was cut the rubber retainer off. That's been quite a long time ago, and many oil changes.

You can cut the rubber retainer off before taking the clamp loose the first time.

I did the same thing. Ended up buying the filter cap thing, ripping that stupid plastic tray out of there and have been happy going thru the fender.
