[QUOTE="Buellstunter, post: 1134268, member: 11549"] Ok. Little back story. So when I bought my truck about year and a 1/2 ago it had just been studded and deleted. Had set of new ford oem heads and oem gaskets put on, blue fuel spring 6.4 banjo bolts oil cooler all new injectors warren 190cc stock nozzles new glow plugs as well as a few other things done. About a month later an injector went bad and I had it replaced after trying rev x While there I asked them if they had a way to test head gaskets, he said no true way to "test" for sure but would check it out. He said he did a leak test on it. (Cooling system i assume) and in 3 days it dropped less than 1/2 pound. All was well. Drove it on a 2300 mile trip no issues. So over next few months Slowly was noticing deltas getting high so tried the coolant re-route trick to get a little more time out of my cooler. After I did the coolant re-route where you come out of oil cooler housing with a 3/4 hose and "T" it into heater hose under degas bottle I noticed my truck would spit coolant out cap. So put a gage on my bottle and it would only go to 10-15 lbs after normal driving. I replaced cooler and trucks temps were all good now. ECT 185-190 and EOT at 187-192 around town. Highway at 75mph might hit ECT of 195-198 EOT of 197-200. But would still spit coolant. When jumping on it and Would smell coolant. Then I would pull over and gage on bottle would still be at 10-15psi. I found that keeping just barely enough coolant in bottom of degas bottle vs 1/3 full it wouldn't do it as bad. And this all started after the coolant re-route. So the other day it spit out coolant again after getting on it to pass someone check gage and it's running like 15-16lbs. So I decide to run a hose inside truck and put gage where I can watch it. Running down hiway at 70mph ECT @ 178 EOT @ 180 lay into it steadily and boost up to 25psi and I see gage go from 16 to about 18 then it fluttered there a bit and I left off dropped right back to 15psi I smelled antifreeze so pulled over. It spit a little bit so I removed cap on degas bottle to relieve all pressure. Pulled out went down hiway about 3-4 miles and pressure had climbed up to about 6lbs again so I am a little pissy thinking I got a head gasket issue so I jump on it at about 70 it kicks down into passing gear and hits about 25psi boost and I watch gage go from 6lbs to 8.5-9lbs. Now I'm running an edge cts tuner on top tune. Checked ECT it was at 185 and EOT at 188. I would think if it's a head gasket issue it would jump up more than 2.5-3 lbs with hardly any pressure in degas bottle and I would get way hotter ECT than a 4deg climb. Wondering if anyone else who has done coolant re-route is experiencing same issues and that's the culprit or it's head gaskets. And another thing is it doesn't blow any white or bluish smoke. Just a little bit of black smoke when doing this. [/QUOTE]
