Post coolant stains under hood?

this is my first post on the site so bare with me..... just bought my first 6.0. always told myself i would never buy one but anyway........ its a 2003 f-250 king ranch 6.0. just turned to 120,000 miles . one owner prier to me. any way. bought it at a small dealership and of course every dealership power washes the **** out of everything. after i got it home i started looking it over and the inside of the hood has white stains. looks like salt water stains...white outline etc... i just figured it was from them power washing under the hood. well i was talking to a mechanic i know and i asked him if it was possible this was coolant spray. possibly the head gaskets blew at one point? he said it could be possible but not for sure. i pulled the Vin and it came back clean the truck has never had a warranty claim. or been in the shop for anything.
it had a knn cold air intake on it when i got it. nothing else. so he probably had a tuner on it? why else would you put a knn on it. had stock exhaust.

what im trying to figure out is how i could tell if it ever had head gasket work. for all i know it could have been upgraded to arp studs.(wouldn't that be nice!!!!!!!) is there any way to tell?

i would hate to tear into it to put studs and find out it was already done!!!

with all of the 6.0 probs i know of i have done some upgrades
4"MBRP TURBO BACK
knn intake (already there)
sct x3 tuner running economy tune

thanks guys for your time. help is appreciated!
like to do something before lol

Start be deleting the egr cooler. Studs, look at the head on the bottom side, do you see a large bolt or a 12-point nut? If you see the nut, you have studs. As far a the residue, if it is over the coolant bottle, your cap could be bad? Could be left over from a blown hose? Just keep an eye on your coolant level.
Best thing to get would be an Edge Insight to monitor oil and coolant temps. Anything greater than 15 degrees means your oil cooler is clogging.
There are lots of things to do to these trucks.
Coolant filter
Switch to ELC (CAT EC-1) coolant
Oil bypass filter
CCV reroute
6.4 banjo bolts
Studs
There are lots of other things..... Those are just good preventative measure items.

To find out if you're truck has had head gasket work done you can have you're ford dealer run an oasis report and tell you if they have been done, if it's out of warranty then you'll probably never know, as far as head gaskets or egr cooler leaking you will see signs of coolant leaking from the cap on the degas bottle or out the exhaust.Bondsman is right on the 15 degree diff. between oil temp and coolant temp. but these temp differences need to be monitored under the proper conditions, (running hard or under heavy load for some time. the new calibration files available monitor these conditions for you and turn on the wrench light if the temps do not jive. this condition leads to poor heating concerns and when you're oil cooler really fails, oil in coolant, keep an eye on you're coolant as ford gold and oil create a nice sludge and if gone unnoticed long enough will turn into a paste that is literally impossible to flush out. Welcome to 6.0 country

Welcome to the forum and the world of the 6.0
With nothing on the Oasis report could be good or bad. The good is that you got a good child or the bad is that it is turning into a problem child. The K&N air intake is not the best filter for these 6.0s the stock filter is good to 500HP one of the best. As already stated the Edge Insight is a must on the motors because you need to know the temps, coolent filter to remove the casting sand, fuel pressure gauge pressure under 45lbs will kill injectors, oil by-pass the injectors love clean oil use only Ford filters + Syn oil, centane boost also to keep the EGR valve and turbo clean and after it warms up about everyother week drive it like you stole it. Hope this helps

thanks for the help guys

i agree having a good report could be good or bad, the fifth wheel has defiantly been used so im assuming it was pulled. i have a hard time believing a 6.0 with 120,000 miles hasn't had any problems.(knock on wood).

i do have a warranty 3year/36000 miles that just started. only got it because its a 6.0L

Im kind of maintenance freak so ill defiantly keep an eye on the coolant etc..

i am going to switch to amsoil syn. the dealership changed the oil when i bought it so its only got about 1000 miles on the oil. i dont know what kind of crap they use so im gonna change it soon.

as far as an insight goes dont have the cash right know

i m gonna check out the head stud situation. i really dont want to stud it right know. im 17 so i dont have $4000 to dump to studs. i know im driving a king ranch f250 bla bla bla im sure im gonna catch all kinds of crap.

and yes i paid for it every dime,plates,insurence ect..

ill check back in with some more info on the situation

The white stains may be coolant caused by a variety of reasons. I know that it's expensive to put another $400 or so into something, especially at your age, but it's really critical that you get SOMETHING to be able to monitor your engine specifically oil and coolant temperatures. I'm one of the minority who think that the 2003 is one of the better years, but because of the age of the truck you're at risk for items such as oil cooler failures. Having something to monitor your engine can actually SAVE you a lot of cash later on. I believe that the oil cooler failures are responsible for many (not all) common issues on the 6.0 including turbo failures and injector issues because of excessive oil temperatures. This stuff is very expensive to fix, and knowing the operating temperatures of your vehicle can help prevent this.

Find a way to get something to monitor these temperatures (even if it's borrowing from someone just so you can see what it's like right now), it's really important.

well it looks like im gonna pony up for a insight.
i make pretty descent money 35 hrs week @ $15 a hour is pretty damn good money for me at 17.

just the fact that i spent $23,000 on the truck $400 on exhaust $400 on tuner, $1100 on tires. **** adds up fast.

i guess what im trying to do is put off studs and egr for a while. so i can recoup some money.

what do you guys think about. pulling with the truck. i haven't done any pulling with this truck yet but in the summer i pull anywhere from bobcats,lumber,other vehicles. since i do construction for the family business.

should i not go to crazy with the truck? i dont want to end up having to replace the whole motor

did any of this make sense?

One of the reasons I like the 2003's is the robustness of the EGR cooler. Don't be overly anxious to replace things on the truck which aren't broken and might not ever break. Getting something to monitor the engine THEN replace what is necessary is going to be the most cost effective way to go. Basically, if it ain't broken don't fix it, but fix what IS broken and you'll be much happier.
