Oil/fuel filter housing

4.10s will make the oil temps go down like stated. What are boost levels looking like? I bet theyre lower than they should be pulling 11k.

,he biggest thing with the gears is the fact that they do you make all he load off the motor. Hence his egg issues, higher oil temps, its because there is no drive pressure left for the turbo. It will pull so fast through the gears it pegs the egt gauge in a matter of seconds. Now granite it dies cool back Down very fast, but you that has always been something I've tried to address earlier too. Was just a matter of money for the previous owner. It was in the agenda just never got checked off. Personally j wouldn't of gone over 4.30's with this truck, but I didn't do the original gearing anyway. Someone else sold him that unfortunately, but that was also before anyone offered 4.30's for the Dana 60 axles.

Thanks for the explanation.

Flay footing it from a dead stop would only get you about 25-25 psi. With the converter locked you might see 30.

Boost levels are lower than the Ex. I've heard that the Atlas 40 tune can do this but I have no experience with FICM tunes. The FICM tune was written after the SCT tune. Not even sure if there needs to be coordination between tuners on this one.

As to Hawgs point regarding the gears I'm still confused on this one. I'm running down the road at 2200-2500 rpm, which is about 65-70mph according to my GPS. Isn't this engine out of it's normal operating range at this rpm? Going to 4.30s or even 4.50s will make the engine spin even faster.

No, going to anything lower than 4.88 (i.e. 4.50s, 4.30s, 4.10s, etc) will make the engine slower for the same speed but it will load the motor more.

As far as the Atlas 40 tune goes, there is a possibility that this is your problem (the FICM tune is fighting the ECM tune or vice versa). I have tried various FICM tunes (from both Bill and IDP) and when I ran Bill's Hercules 100 tune, my truck made no more power that I could feel and all it did was smoke like a pig and run hot. Bill's Economy FICM tune felt like it made less power than my IDP Mild FICM tune and ran the same temp wise. The Atlas 40 is a mild FICM tune so I doubt that it is the problem. However, what size nozzles do you have on your injectors (just to rule this out)?? You could always just flash your FICM back to a stock strategy and see how it does but I really dont think that the Atlas 40 is the culprit here. At least I wouldn't blame it just yet. JMO of course.

Try this...with your truck in park, rev the engine to 2500rpm...what kind of boost does it make? Should be FA.
Now put the truck in gear, hold the brakes hard, and try to rev the engine to 2500 rpm...now what do you see for boost? If you were able to even hold the truck from shooting forward, you should have seen over 20 psi of boost easy.

What I'm trying to show here, is that even at the same rpm, if there is no load on the engine, there is no drive pressure to drive the turbo, and no boost.

Bigger injectors fuel the same whether there is a load or not, so if the turbo isn't providing the extra air, it's all just going to be heat.

By using lower gears, 4:88's, the engine is reving higher, but it has less load on it then if it were running a set of 4:10's or 3:73's.

Less load on engine, = less boost = higher EGT's

BTW: With 4:88 gears, the driveshaft turns 4.88 revolutions for every one revolution of the ring gear in the rear end.
So if they swapped to 4:10's or 3:73's the engine would rev lower. (4.1 revolutions of the driveshaft, to one of the ring gear....or tire.)

Not trying to be a dick, just trying to help.

Not to hijack your thread, but does anyone know the Ford part number for the 6.4 oil filter housing. I'm looking to do the fuel bowl delete on our new shop truck.

Thanks in advance!

Has anyone ever heard of swapping out the 6.0L oil/fuel filter housing for the 6.4L oil filter housing? I'm wondering if there is any possibility that the existing 6.4 oil filter housing is allowing a greater percentage of the oil to bypass the oil cooler in this application.

Pizza pig · Sep 21, 2012

I've been using a 6.4 filter housing for like 8k miles, theyre the same thing just san the fuel bowl.

Is the oil cooler bypass valve available as a sub-assembly? I suppose there's no way to check it for proper operation...or is there?

No, you can only get it as a complete assembly with the oil cooler top section. Still trying to catch up with you Tom. I'm at the shop for the next couple hours if you wanna chat. Gotta get ready for the truck show tomorrow......
