06 puking with ARP headstuds
Long time viewer first time poster.
I purchased an '06 with 130,000 on the clock and purchased it with a block/head and tranny aftermarket warranty.
I have spent tons of hours on this forum and others before purchasing this rig to learn about the motor. I am loving the cab size and the power of the motor. As purchased it had an egr delete, aftermarket intake, 4" exhause and SCT tuner with exhaust gas monitoring.
After only 6 weeks I noticed that I was filling up the coolant resorvoir to the new minimum with the coolant completely disapearing to the bottom from time to time. I did not overeact to the fluctuations at first. But, then I began to notice that I was getting the white residue. So I went and bought a new coolant cap, still burping. Next up I monitored the EOT vs ECT and got a delta no larger that 8 degrees at WOT warmed up and climbing up a hill. Finally, I tested the coolant pressure using a 30psi gauge off of a t-fitting on the resorvoir. Sitting in the drive idling it would reach 15psi in 5 minutes time. When driving it went up as high as 18 psi before leveling off when letting off the throttle.
When I dropped the rig off at the ford they called me back to say that it appears that I already have head studs put in the motor. The warranty on covers the labor directed toward the block, turbo, head and associated gaskets. They're intial thoughts are that it is the head gasket but they have not performed a compression or leakdown test.
I have never seen hight exhaust gas temps over 1000 F and the turbo has never spooled higher than 25 psi with me in it. The tune that was in the truck when I got it and was driving it is labeled performance tune? Not sure who wrote it or if its and SCT canned tune. I have never seen coolant on the ground or elsewhere in the truck. I bought if from a dealer and they won't give me the previous owners name to ask questions to see who or how they did the ARP upgrade.
How difficult or costly is it to perform a compression/ leakdown test? What other reasons could there be for puking?
I have worked on gas rigs since i was in my teens replacing motors, transmission, etc. but this is my first diesel other than a small import a number of years back. First time I have had to rely on a dealer and the uncertainties of pricing and warranty coverage. I would have dug into the problem further myself but wanted to let the warranty take care of it as I have limited time to be crawling in an engine bay lately.
Thanks for the considerations.
