2007 F-550 that runs at about 15k weight. 70,000 miles.
I know this subject has been covered a lot but please bear with me. I should have tested the head gaskets before I torn the motor down, but I didn't so I don't think I can check them now.
Truck kept having issues, after sitting for a couple of weeks it would start rough, purge white smoke and water would be pouring out the exhaust (not tail pipe but near muffler). After you ran it a bit the smoke would go away.
Once in a while it would lose all power barely able to move. If you let it sit, and drained the water out of the fuel it seemed to improve.
Lately it would run alright for a while until it came to full operating temp, but then it would lose power and start smoking again. Antifreeze would be disappearing quickly, and the truck would over heat. Not a gradual creep, but would spike all of the sudden and then fall back off after a couple of minutes. Last time we added antifreeze it was leaking some near the front passenger side exhaust manifold. Lots of stuff in there so its hard to see where its coming from.
We had it to the shop over the last two years and them replaced the turbo, a couple of injectors and the EGR value. Sympums would keep coming back and we kept getting huge repair bills.
We thought it might be a injector problem and wanted to take them out have them all bench tested and replace the EGR cooler, and oil cooler.
Injectors all tested fine. Got a new EGR cooler that has the tubes that run through it. EGR valve looks good. No water in the oil. Valve covers had a very little bit of water/oil residue on both sides.
I've been reading through a lot of posts and didn't realize how often the head gaskets go bad. I'm not opposed to replacing the gaskets and the head bolts with ARP, but its such a pain to work on the truck with how cramped it is in there and I don't want to remove my A/C box and purge the system which is working fine.
I'm just about to put it back together without doing the head gaskets, but wanted some opinions first. If they are bad now would be the time to do it.
Sorry for the long post and looking foward to your help.
Thanks
