2014 Oil Filter Access

[Dieselnerd]

I've been reading about removing the oil filter from the top after removing the air hose from the air cleaner to the turbo. Sounds like a lot of trouble.

Looking in the fender well on the passenger side of my truck, it looks to me like they have provided an access hole in the fender liner right in front of the oil filter. I haven't changed my oil yet but this sure looks to me like a place to reach in and remove the filter. Was this added in 2014?

Here is a picture of my fender well with a clear view of the filter and what looks like plenty of room to get it out.

It won't fit through the hole without spilling oil all over the place. Check out my thread on this subject with pictures, Ken Irwin

Not even with the plastic zip lock bag trick?

You can pull it through the side, what happens is after you unscrew it, let it fall down between the engine and chassis. That cross-member is molded in such a way to hold the filter straight up and down. Then you can either wrap it in some plastic or put some cling wrap over the top and pull it out without spilling. Clearances are tight but its possible. Then when putting in a new filter, you still need to put oil in it. Then wrap some cling-wrap or glad press-n-seal over the top and toss it in from the side. Really important now, remember to remove the wrap, then proceed to tighten the filter back up to the boss. Either way is a lot of work. You'll either need cling wrap, or some extra time to undo the intake if coming in from the top. Vid below

I've read several times here on the boards that pre filling the oil filter is bad JuJu.

I don't know why because as long as you're not overfilling beyond capacity, I see nothing wrong with pre filling an oil filter.

That was because sometimes pieces of the foil from the top of the oil bottles got dropped into the center of the filter. They went straight into the engine and sometimes got caught in the spray nozzles that cool the pistons or another narrow oil passage. I fill my filters with oil but not to the very top. I bet many dealers put them on dry.

I doubt the slight time it takes the engine to fill the filter causes much engine wear. I guess you have to weigh the chance of debris in the filter vs the extra wear and decide for yourself.

I have always pre filled with over 1,000,000 miles on my rigs. Just make sure you peel off any thing that may go into the oil filter. I have not seen foil on an oil jug for a long time.

My first filter change went OK, took the air tube off and did the removal from the top. I bought a filter pliers that works well through the wheel well. I will NOT pre fill the filter, just my decision after finding out how fast the Cummins moves oil. Dont ask how I found this out.

Gonzo Tell me how you found out how fast it moves oil. I promise I won't giggle.

I watched a CAT 3406B blow the oil filter apart in my shop one day due to a stuck pressure relief valve right after it had been serviced. Pumped a good 5 gallons right on the floor before we got it shut down.

Hence I will NEVER have a remote start device on a Diesel engine. Always present and accounted for when I start one. Never know when the relief might stick.

I had a reman International DT 466 on a stand on the shop floor. I had changed the oil and filters (Two large inverted oil filters)and wanted to do a test start. I THOUGHT I remembered which way was off on the fuel pump and hit the starter to crank and prime the engine before opening the throttle to let it start. WELL what I thought was off on the fuel was in fact FULL RACK!!! The darn thing fired on its first rev over and went to full RPM. There was a oil pressure port that I forgot about :-laf and in about .7 seconds new engine oil shot through a 1/16" line to my newly white painted 13' shop ceiling!!!!!!!!!! This line was from the end of the last cam bushing (the last spot to get oil).

This engine even had the oil cooler drained, So that would have been (about) a half quart for each oil filter and a quart for the oil cooler. I dont know the specific GPMs of the Cummins vs the IH 466, but I assume that they are at least very similar. One misunderstanding folks have is how much residual oil film is left on bearing surfaces in any engine. And the highest wear spots are on the lobes of the cam which are NOT pressure lubed. All things considered and having near 50 years of rebuilding engines I will not start filling filters as I have NEVER seen unusual wear due to oil change startups.

I've seen similar happen with Cummins and I-H diesels in our shop when started at idle speed. Oil pressure comes up almost instantly in engines with drained oil coolers and dry filters. We didn't pre-filled oil filters in our shop and I don't either. The residual oil left in these engines drips for days after the oil is drained and the oil pan has been removed.

How would you pre-fill inverted or horizontal engine oil filters found on many engines?

 

[Gonzo 1066]

I have used a pressurized oil tank plumbed into the oil galley to prime new engines and fill the pan. However on any engine that I build I always use a high zinc assembly lube, seems counterproductive to wash that lube out of the bearings with oil before cranking. Although this does fill the filters. And there is NO WAY to fill inverted filters when installing.

This discussion is alway entertaining to watch!

If I have a oil filter that can't be pre filled I crank engine for 30 seconds then start.

 

[jhenderson]

I think all this ruckus started in WW II. Radial aircraft engines had pre-lubers that ran for up to 1 full minute before a cold start. The engines often took up to 1 minute after start up before steady oil pressure was observed. They also used the planes fuel supply to thin the oil in cold weather, and counted on it evaporating when the oil heated up. That's a far cry from the 1-5 seconds our engines take to make steady oil pressure.

It is entertaining to me to find how many people think the Cummins in our trucks is a tender fragile little engine and needs to be treated with kid gloves. One of my mechanic buddies insists on changing the oil in his Cummins at 3000 miles with Amsoil full synthetic ($$$$). Says he wants the truck to last. When the reality is that these engines, in the WORST cases, will outlast the rest of the truck.

I have a '97 12 valve 5.9 I bought it new, has about 400k on it now. After I shut the truck off, it will syphon about half the oil in the filter back into the engine, in about an hour or so. This is nice if you have the time to let it sit, and allows you to lay the filter over quite a bit without spilling. I do have a '14 now, and was wondering if they work the same way? If so, I might be able to lay it over enough to pull it out the side of the access hole when I do the first change.

 

[Gonzo 1066]

When I did the oil change on the 2013 I let the truck sit overnight, the filter was NOT full. Maybe below 1/2, following the wisdom of the pre fill the filter guys everytime you start your truck you should remove the filter and top it off?
