And that guys post was also copied from anothers article. PGREENSVT is the original author. There is a plethora of knowledge on that site. 6.0s are simple. Bad batteries kill FICMs, then FICMs kill injectors. Bad oil coolers kill egr coolers, bad egr coolers then kill headgaskets. So watch your temps, watch your FICM voltage, clean filters and your good.

Idling the powerstroke does nothing to the oil cooler.
The problem is well documented all over the net, do a search.

Not true....the oil coolers clog up in the coolant passages from the silicates in the coolant. When this happens the transfer of heat doen not take place and the oil temp rises. This why you should monitor the ECT and the EOT, the spread at 60mph full operating temp on level ground should be no more than 15 degrees.

5w40 is better on 6.0s. Its not for the oil cooler though, its easier on the fuel injectors. Coolant is the enemy of the oil cooler. Run CAT ELC red coolant and you wont have a problem as long as your cooler is not already shot.

Black Onyx have now been proven to be garbage. If you purchased Black Onyx gaskets Victor Reinz will give you a new set of redesigned gaskets for free. I agree block prep is key. I have heard ford procedure for checking the heads for flatness is a joke. Some heads have come new from ford and are not flat. I just did head gaskets and studs on an 05, ended up machining the heads a few thou just to flatten em out. I am not a tech. Just a hobby. I put 420 rwhp on my 04 6.0 with 200k on it.

thats good to know. The thing is, im a little gunshy when I get a customers truck with no heat and i know why... Then I dont know if they are letting go due to improper torque using studs or the gaskets. So when I have the cab off I know that if I use the bolts and factory gaskets it will leave in proper working operation. Even my own truck has bolts and factory gaskets. After a oil cooler kit and egr delete she does just fine.

If the truck is an 04 or older, no heat can be caused by leaking wheel bearing/hub seals. They are vacuum actuated. When the seals go it also loses vacuum to the heater controls. There is a T in the vacuum hoses next to the vacuum pump and resivior. Unhook the line going to the front axle and plug the remaining vacuum line into the resivoir box directly.
And for the PVH style hubs, If you shift into 4x4 and your mode goes into defrost, you know you have a leak. There is no vacuum sent to the hubs until commanded.
