6.4 puking coolant..
Ok so i bought an 08 6.4l and two weeks into my ownership the oil cooler started throwing codes.. so I take it in and while the cab is off I had them delete the EGR, put HPS reinforced radiator hoses, sinister coolant filter, S&B intake, 5" straight pipe, head gaskets & ARP head studs, and one of the heads needed to be replaced. I get it back and it's making a swuealing noise I take it back to them for an up pipe job. I get it back AGAIN and now it's puking coolqnt as fast as I can fill it.. what could be causing the puking? There's no EGR coolers to go bad, and it has a new head with head gaskets and studs.. what else could even make it like like this? I would think blown head gasket would be the only way it would puke? Any help would be appreciated at this point.

I called them and they just told me the shop is full right now and they can't get me in yet.. but I drove the truck today and it didn't puke any but when I shut off the truck I can hear the reservoir bubbling and the coolant level rises up? I'm confused as can be on this and I'm hoping it's not another head gasket.

This is for the team.
I just got off the phone at the parts counter to order a degas cap.
Just so happens their tech was standing on the other side of the counter.
The Tech said that the stock caps were inadequately manufactured and could hold pressure way off the board resulting in upwards of 10 pounds more pressure than designed.
They corrected it with the new style. He said also the manufacturing date should be after 2012 on the package.
He also was burbbling about how many 6.4's come thru with leaking coolers and intrusion of seals into the oil system thru coolers because of the pressure.
Makes perfect sense to me.
Can't believe this expensive engineered engine could suffer catastrophic damage over a 12 dollar part.
Crackin a beer!!!
Heads up people (6.4 people) My cost, 12.22

I put the updated cap on the truck the day it started blowing it all out and it slowed it down but didn't stop it..

I think someone said that the 6.4 isn't supposed to have a thermostat. I did some looking and it seems that some people think it could be overfilled with coolant or have air trapped in the coolant system. Take a look at this thread.

Yeah I sold my 7.3 to buy this 6.4 thinking studs and a delete would be a fix all but now I see why everybody told me it was a bad idea -__-

Kenny, just an update, my problem is lower radiator hose at the block.
I'm going with the 249.00 blue hoses offered on Ebay with fittings, double o-ring style.
Mish wants 495.00. Really?!
