BustedKnucklez Posted March 4, 2009 Share Posted March 4, 2009 I'm finishing up a 6.4 that I needed to replace headgaskets, front cover, turbos, oil cooler, and t-stat housing. Of course the jack ass body builder welded the friggin ladder rack on so no way to do cab off. Anyway, I don't know how to flag it to get something half-way decent on it . Any suggestions?

Keith Browning Posted March 4, 2009 Share Posted March 4, 2009 The only suggestion I have is to look through the labor time guide to make sure you don't miss anything. I am curious as to how long it took you though. Quote Link to comment Share on other sites More sharing options...
Aaron Posted March 5, 2009 Share Posted March 5, 2009 Would have hacked the fuckin' ladder rack off with a sawzall, and turfed it in the back when I was done. Just suits my mood lately. Quote Link to comment Share on other sites More sharing options...
BustedKnucklez Posted March 5, 2009 Author Share Posted March 5, 2009 The only suggestion I have is to look through the labor time guide to make sure you don't miss anything. I am curious as to how long it took you though. I started tearing it down last week on monday 2/23. Its running right now as I type this message. I would have had it running sooner but I sent the heads out for pressure testing, and waited today for about 2.5 hours for some parts. Not bad considering the last job I did took me about 3-4 weeks of off and on working on it. Quote Link to comment Share on other sites More sharing options...
Mikill Posted March 5, 2009 Share Posted March 5, 2009 I'm just curious as to why some people are doing headgaskets on 6.4's. Myself or no one else in the shop have ran into headgasket problems on the 6.4s. I personally have done a short block, hp pumps and gaskets, egr coolers, front covers, fan clutches, turbos and etc but never ran into headgasket problems.

BustedKnucklez Posted March 5, 2009 Author Share Posted March 5, 2009 Performed pinpoint test for coolant loss as per WSM. All passed except the combustion gas in cooling system aka block test. Pulled both EGR coolers and heated and air pressure tested-no leaks. As per hotline, replace headgaskets. There must be something wrong with the headgaskets because Ford did update them to a much thicker multi-layer metal gasket with black sealing surfaces.

Aaron Posted March 6, 2009 Share Posted March 6, 2009 Pretty much all of the head gasket replacements I've heard anything about have been "As Per Hotline". Aside from the heads with the sticky valves, or any other issues, aside from genuine "head gasket" issues. As Per Hotline, as in my signature Quote Link to comment Share on other sites More sharing options...
Mekanik Posted March 6, 2009 Share Posted March 6, 2009 Wow, headgaskets leaking on 6.4ls. We haven't seen any, but I have seen several de-gas bottles with coolant stains on the outside. Quote Link to comment Share on other sites More sharing options...
BustedKnucklez Posted March 11, 2009 Author Share Posted March 11, 2009 Well I figure it must have been the headgaskets because if there were combustion gases in the cooling system and the EGR coolers were fine, than what else can it be? Anyway, I flagged the thing and managed 40.9 hours with lots of MT/Labor Op combos. They sent it to the Warranty guy in Dearborn to see if it will fly. Im crossing my fingers. It's definately justified in my opinion. It was a really long story. Quote Link to comment Share on other sites More sharing options...
robp823 Posted March 12, 2009 Share Posted March 12, 2009 what are you using to test for combustion gases in cooling system?? Quote Link to comment Share on other sites More sharing options...
toby Posted March 12, 2009 Share Posted March 12, 2009 We have a tech at the shop that just pulled heads on a 6.4 for venting from degas. What we found was amazing and I will have to try and get pics up. On one side there is a circular crack in the head just next to one of the cylinders. There is also a small hole in the head along the sealing ring. There is a hole in the head on the other side also along the sealing ring. Its the strangest thing... I will try and get some pictures of what I am talking about. Quote Link to comment Share on other sites More sharing options...
BustedKnucklez Posted March 12, 2009 Author Share Posted March 12, 2009 what are you using to test for combustion gases in cooling system?? Using a run of the mill block tester with blue combustion testing fluid. I was pulled in to the office today and advised that I am only going to get 33.5 hours for the job. Im definately taking it in the cheeks on this one. Quote Link to comment Share on other sites More sharing options...
eastendpowerstroke Posted March 13, 2009 Share Posted March 13, 2009 This post has made me think about something we may find useful and efficient. a labor op Forum for things such as this engine R&I cab on vs cab off, head gaskets cab on vs cab off etc. A basic listing of proven winners that we can use for quick reference and add or subtract as required? What do you think Keith? Quote Link to comment Share on other sites More sharing options...
cbriggs Posted March 16, 2009 Share Posted March 16, 2009 I had cab off of a flat deck with spare tire rack over cab. Warranty paid 3.5 mt to remove and reweld spare tire carrier for cab removal. Quote Link to comment Share on other sites More sharing options...
Mekanik Posted March 16, 2009 Share Posted March 16, 2009 I had cab off of a flat deck with spare tire rack over cab. Warranty paid 3.5 mt to remove and reweld spare tire carrier for cab removal.You seriously cut and re-welded the spare tire carrier? I had one that I unbolted and mover the ladder rack on. The time was totally legit, and I was a little dis-appointed that I had to fight WPI to get the time. Quote Link to comment Share on other sites More sharing options...
rlchv70 Posted March 26, 2009 Share Posted March 26, 2009 Well I figure it must have been the headgaskets because if there were combustion gases in the cooling system and the EGR coolers were fine, than what else can it be? Glow plug sleeve, cranked head, cracked case. Also, the EGR coolers sometimes only leak when REALLY hot. Quote Link to comment Share on other sites More sharing options...

DamageINC Posted April 10, 2009 Share Posted April 10, 2009 Oh my god, 33+ hrs would have been a dream for me. I short blocked a 6.4 once and got just over 20 IIRC. Couldn't squeeze anything else out of our service director because of the 126 tap-dance. Fun fun fun! Dave Quote Link to comment Share on other sites More sharing options...
