EGR, Oil Cooler or Head Gasket Help
Looking for some help ....... I have a 04 F-350 with the 6.0 psd, entirely stock. The truck has not been run hard (limited light towing & snowplowing) but has gone through long periods of idling. A few weeks ago it started blowing black smoke out the exhaust and would not go over 10 miles per hour. Towed to local shop and they replaced Cam Shaft sensor and cleaned up a disgustingly clogged EGR valve. I have since disconnected the valve.
Now, the truck is blowing white smoke and is burning anti-freeze. It actually was down on anti-freeze before the break down too. So ....
After lots of research and educating myself, this would appear to the EGR cooler, Oil Cooler or head gaskets or some combination thereof. I am considering buying an EGR delete from Gillett Diesel and replacing the Oil cooler while I'm there. BUT ... I'm worried that maybe the head gaskets are blown and I'm not sure I want to try those on my own.
So I am looking for some advice:
Is there any way to check and see if the head gaskets are blown? Any symptoms I can look for?
Is anyone aware of an aftermarket oil cooler?
Anyone tried the kit and install from Gillett and can share experience?
My truck is out of warranty and the dealer's best estimate without actually diagnosing is $3600 for EGR cooler replace and Oil Cooler replace. I think I can get the delete kit and new oil cooler (at least from Ford) for about $1000. If I new going in that the head gaskets were blown, I would probably just take this to a shop and let them go to town since at that point its probably worth it. On the other hand if I had some confidence that the EGR delete and new oil cooler would solve my issue, then I'm willing to give up a weekend to becoming a psd mechanic.
Any advice would be appreciated.
