Just curious, I saw a video where a guy doing a shade tree compression test where he removed the oil cap on a 6.0 and held a paper towel loosely over the fill port to check for blow by.
I the video you could see the towel blowing right up and fluttering as the truck was running.
So... I went out and tried this on my truck and I used a tissue and there is some, very slight, movement of the tissue as the truck is running.
Question is, is it normal to have some pulse of air coming up out of the oil fill port while the truck is running or should there be nothing at all?
My stats are:
2005 F250 Reg Cab 6.0 all original no upgrades
98,500 miles
Change Oil, Oil Filter every 5000 miles
Use Shell Rotella T6 5W-40
Clean EGR Valve at every oil change
Change Fuel Filters and Air Cleaner every 10,000 miles
Still running Gold Coolant but drain and replace every 20,000 miles
Deltas are at 10-14 degrees (was higher but backflushed oil cooler and shaved 8-10 degrees of delta)
No oil in coolant and no coolant in oil and motor doesn't loose any oil or coolant
Most people worry too much about blow by gases. After all, we have a 6 liter engine, so you may be allowed to see something. I have installed a CCV reroute.
Hey thanks for the info and video.
Thats a nice looking motor and truck.
Are you running a remote air cooled oil cooler?
Also is that a CTS2 or 3. I have the CTS3 but I don't have coolant pressure or fuel pressure, how did you do that.
Lastly, what are those two pipes on either side of your truck with the blind flange plate on them?

Thanks. I can only advise anyone not to change the original oil cooler system and not go to a aftermarket system. If the oil cooler, and the cooling system in general is well maintained, it needs no changes here except for a coolant filter.
The programer is a Edge CTS2, the coolant and fuel pressure can be displayed via additional pressure sensors (also the exhaust temp sensor).
The "tubes on each side of the truck with the blind flange plate" , are foldable hydraulic cylinders with which I can level the truck in bad terrain, please click on the picture link in my signature. If you look closely you can spot the front hydraulic cylinders. I have installed front and rear each 2 pcs.
I have the tool purchased from eBay. It’s a ford rotunda tool that screws into the oil filler with a calibrated orifice. The bad engines with major blowby usually will blow the oil cap off. If you feel very strong pulses that can be a sign of a cracked piston. A nice steady stream of “low” pressure vapor flowing out is normal.
So Hartwig advises against "other than OEM" oil cooler. I've considered a BPD air-to-oil cooler when the time comes. Thoughts?...
If you want to spend the money go ahead, I haven't heard much negatives about it but there also aren't a lot of people running them and I don't believe I've seen any data from people towing heavy in hot climates. BPD is located on Phoenix so I assume they did some heavy duty testing on it.
OEM oil cooler with a clean system works just fine. The oil cooler kit can be found for around $300 plus another ~$150-200 in gaskets/misc if you can do it yourself vs $2k for the BPD system.

I recall some folks complaining of running hot with their air to oil cooler. Problem is they offer several size coolers, so it might be folks ordered too small a cooler for their duty and climate...
Thanks for the input guys. I don't mind doing work on the truck, or spending money where it is needed. I see a lot about the difference between oil temp and coolant temp and how to solve that problem. The Air to oil cooler may very well be a good system, if you need it. As a daily driver (mostly), I probably don't. Seems like a better course would be a good flush and coolant swap to ELC.
