6.0 DIY oil cooler and filter bypass 

Thank you so much for all the great videos Josh! Greatly appreciate all the knowledge you cram into them! So I have been researching for weeks on doing a remote oil cooler install since my factory oil cooler on my 2004 F350 6.0 is completely plugged (40° delta). I flushed it with restore & restore plus, even backflushing the oil cooler with an OTC blast vac, unfortunately delta didn't improve. So going with a DIY setup because $2k for a name brand system that comes ready to bolt up is just absurd to me, not to mention the air cooler is made in china. Your DIY is the best looking design I've seen out of all the DIY setups. So to go with the cleanest looking setup I just purchased a used complete E350 oil cooler housing that includes the fuel filter housing all the way down to the oil cooler. I like this way so much better because it eliminates the F style oil housing and allows the oil supply line location further away from the turbo. Well today after stalking your youtube videos again LOL I ran across your other video "6.0 powerstroke oil bypass review" that you did back in June. I seen you mentioned the E350 fuel lines that hook to the housing/pressure regulator are different/shorter. I was wondering if its just the length that is different and if its possible to just modify my F series lines to fit. Like cutting the ends (banjo/flares) off and using braided ss lines with the F series ends. The reason I ask is because I'm trying to do this as cheap as possible and I just priced some used E350 fuel lines and they'll cost more than the oil cooler housing cost me. On a tight budget because I'll be doing head gaskets, arp studs, egr cooler delete(welded ends), stc/dummys/standpipes when I do this install. If my heads are cracked too badly I planned to get your sweet swedish heads. Wanting to do all the work this summer when it warms up a bit so getting my grocery list off all the parts and best places to buy them. For the air oil cooler, I haven't spotted any deals on used Setrabs yet, but if none pop up I plan to go with a new Derale 15875 40 row with -10AN / 7/8" inlet size and 10" fan. Still researching on a oil thermostat and dual oil filter housing that will allow the EAO98 & EABP110 amsoil filters to mount up. Trying to keep all inlet/outlet sizes at a min of -10 size but keep running into the smaller 1/2" inlets/outlets on the dual filter housings. Thanks again!

I did a backflush to my oil cooler and got back 3 to 10 degrees delta, but you have to make a custom pvc tool to use water and pressure air + the chemicals to remove all the junk from the cooler, it took me a whole afternoon, but it's doable and you don't have to modify anything.

I'm slowly stock piling all the parts for this setup. Its awesome to actually see one done instead of planning it out. Thanks for making this video, man. And the others, huge help.

Nice going to have to do this one day. I'm having a few problems first one is my icp usually stays around 580 maybe a few points higher but on a long drive when I come back to a idle it has a small miss to it and the icp is sporadic sometimes up to 600 and down to 560ish 570ish also does it when I turn it off while its warm and crank it back up. Also, learned alot from dieseltech ron he even helped me on Christmas eve one year a really great guy. So your my new go to guy thanks for doing what you do.

Why haven't I seen this video before!? Pure genius!

This was a good video, thanks. I also think that you could further improve this modification by porting the "top shelf". I ported the oil outlet, the one on the out side rim of the top shelf. I did this because with the cooler deleted all of the oil is forced to go through the small oil port in the top shelf. The hole was only big enough to fit just the tip of my pinky, it was smaller then a half inch. Then the oil would go to your filter and air to oil cooler then come back through the center of the top shelf. I also ported the center of the top shelf. I did this porting because by deleting the cooler we are forcing all of are oil through our air to cooler, and you always hear people saying that you need big hoses going to the coolers. With the small oil feed passage you could have fire hoses and you would be able to flow enough because of the top shelf restrictions. I will try to post a photo of my ported top shelf.

Could you not just bolt the van parts on and run BOTH coolers?

Incredibly well thought out and explained, wish you were closer to Houston

Did the van style set up and it works great 👍👍👍

Getting ready to buy all the parts for this have you came across any Issues since you made this video or something you wish you would’ve done besides using the van style Thank you for making this video you saved me $ 💯🇺🇸💪🏻

there's gotta be an easier way. is there no where else you can tap in to and just plumb an air to oil heat exchanger?

I did this... but. No oil pressure for 1 minute after it sits for awhile ! Anyone have a idea why it’s draining back? Please help. Thanks

What are the EOT and ECT when towing with this setup

Great idea!!!! What was your total cost for this project? Do you by chance sell a kit with oil cooler housing and E-350 filter housing already welded? Do you have a parts list you can share?

does this method block the coolant from reaching the egr cooler? also at 2:35 it looks like the holes wont line up properly

What size of cooler are you using? And is the brand of the filter mount? thank you and good work..

I know this was done 7 years ago but, does it work, because I'm thinking of doing it

What size cooler did you use? I have been working on trying to get mine on my 03. Have everything except a cooler not sure what size I should run.

Wow, seems like a pretty involved project. Think I'll just get the upgraded oil cooler, and then install the aftermarket oil and coolant filtration systems.

Like the idea but I see a lot of ways for failure in the future.

So I have a E456 with a 6.0. I have a cracked EGR cooler and plan on going in to do a delete and I've also seen signs of oil in my degas bottle. So I see how using this design works but how do I deal with the factory oil cooler being damaged? Do I remove the original oil cooler and then just let that area fill with oil? If so how do I manage the coolant that's headed that way? I think I'm seeing it now. Remove my van style oil cooler cover, remove oil cooler, replace cover, connect the coolant line in over to the egr out then go online cooler as u have. Old video hoping u still monitor it.

Hi hows it going awesome info on that conversion but I was just wondering would it work if u left the oil cooler in the truck I just hate taking the engine apart because of getting contaminats inside I know it make sense to remove it but would it work other wise thks for your videos awesome content thks

Interesting. Can we use the van housing to create water to oil cooling, instead of air to oil but relocate the oil cooler from the valley?

With the coolant passages blocked, would i be right in assuming i need to delete my egr cooler since it will no longer get coolant?

You are wrong about floating around my friend as that is the suction side and is what holds the screen in place.the screen will come out if you blow air into it.

Hey man I was wondering if you remember what size hydraulic fittings you used on your 10an fittings? I have an lines right now but want to switch to hydraulic lines but can’t seem to find the chart to show what size fittings to get. Thanks!

What would the cost be to do the external oil cooler like that? I think that is a great idea and maybe you could put a parts list together with the part numbers you used.

Why would one want to to delete the oil cooler. Just asking because we are looking to buy one that was already deleted.

Can you send me all the part numbers I'm really interested in this set up. I've been threw 7 coolers

Nice Job! please post a parts list and prices if you still have them

the oil cooler holds the screen in place. what holds it in place if you dont have one

Nice kit! I've been looking to build one myself! Any updates on how it is doing?

Great idea I had a few questions tho I have a bdp oil cooler set up missing the block so Im gonna build my own set up. My first question is how much did it run u to get all that welded and I was ond is will that oil screen be ok and stay in place with nothing pushing on it?

how does the hpop screen stay in place?

Exactly what filters are you using? Can you put the part numbers

Fuel lines if you the e350 top what did you do to get them back in place

Question about the filters used. The smaller is a ea098 and that is a bypass filter right? What is the number on the taller filter? Has anyone tried a Baldwin instead? Thanks.

josh, I enjoy washing your videos, thanks for taking the time. I also want to built this set up do you have the e-350 top part that you can sale to me I will be waiting for your response, thanks

Hi, where did you get the oil bypass thermostat and the dual oil filter housing. Are you using an tube oil cooler or a plate style cooler? Thanks for your time

If you are using a stock e350 oil filter housing, do you leave the check valve and the bypass valve in the housing or do you remove them, and weld the drain back hole up.

I want to do a hybrid of this using the E350 oil adapter, hard lines, and external oil filters, but keep the stock oil cooler (mine is new)... other than plugging the drain port in the oil filter housing on the base, would this work? I will fab a bracket to use the stock F250 (2005) secondary fuel filter and fuel lines, versus an E350 fuel filter housing and lines.

The oil pressure test port on that housing isn't 12x1.5. mine is bigger its either 14x1.5 or 9/16x 18 thread. I bought the 12x1.5.It falls in the hole

That bypass filter surly is not in line right? I didn't see it detailed in your diagram but the bypass is tapped off the main line and fed back in separately otherwise it would starve the engine for oil at high rpm correct??

What size is the oil filter base because the eao98 says it is a 1 16 thread and the base say 3/4 16

hi how do you block the cooland on the intake to keep it from the oil cooler housing

Awesome!

Where do you get the thermostat bypass

I've done the bypass oil cooler using a van style filter housing, and tigged up the holes in the cooler housing. After I got the system bleed and full of oil and coolant. I drove it about 5 miles and now I have water in oil and oil in the coolant. I pulled the oil pan off and did a pressure test on the coolant system.It was leaking ( it looks like the coolant is coming from the front water pump cover and ruuning in the oil pan.) I remover the front cover, water pump and oil pump. I can't find anything wrong. the housing isn't worn much at all where the pumps sit. do you have any ideas? Thanks Tracy

Great video, I would be interested if you would build the kit and sell it,

What happens with the coolant that would go to the cooler?

By any chance do you have a parts kit for this ?

thanks for the helpful tip. i have an 05 e350 van so would it be just as easy? and what did you do about the oil cooler? you said keep the screen on but do I completely remove the cooler?

do you know what the van style oil line number is?

Couldn't you just make a plate to go on top of the manifold to move the oil to the filter and cooler then back?

Can you link to the bypass filter you used?

Hello Dr, I am going to use your oil cooler idea on my 06 f350 rebuild, thanks!. I have a old van motor also 06 E350 and will use parts from that but I want to make the oil filters where I can easily change them so I am going to keep the van filter housing and use regular filters. Any problem in doing this? I also noticed that the van filter has what looks like a back flow valve? it was mounted below the engine, maybe I'm seeing something else?

what is the new delta difference in temp between the oil and the engine coolant with the new air-to-air cooling versus the stock set up of say 6 to 7 degrees?

How much would you charge to get me one done

The coolant can’t reach the egr cooler is it bad if you have an egr delete?

What r the lengths of the lines u used and the sizes

I'm surprised no one has caught this and has not said anything or they have and just letting him look like he does not know what he is doing.the way he has this hooked up he has filtered oil mixing with non filtered oil. when you put the top plate on there is no oil coming out of that bigger hole. when the oil comes back in the filtered oil is dispersing through that little hole which is a bypass with that removed you are mixing filtered oil with non filtered oil. the oil spills over into the biggest hole which feeds the turbo,hpop res and ot,op,sensors and the mains,rods,cam. block off the littlest hole so your not mixing clean oil with dirty oil and your oil will last a lot longer.

I just wish i wouldn’t have bought mine from the get go.

Now all I have to do is, learn how to weld aluminum :).

Can you build me a set up .. how much ?

People say use 12AN hose, you said 10AN. I suppose it works well or something I missed? Thanks.

my name vern can u please call me oil bypass tips

This is a basket of nonsense

Air to oil doesn't cool as well
