6.0 Valve Seats ?????

I was just reading the article in this months four wheeler magizine. They had bullet proof diesel go through a 6.0 and fix all the weak points. I've never herd of it on a forum site. They said that the 6.0 heads have junk valve seats that crack easy they were working on a 6.0 with just 40k on it and they were finding cracks in the the seats. are the valve seats really that bad????

Thats the first I've heard of them being a problem area issue. I would imagine some may have cracks, but if it was a real cronic problem area you would hear alot more about it. I wouldn't lose any sleep over it. If the heads are coming off for headgaskets, its always a good idea to have the heads checked and pressure tested and resurfaced. Harry

Yeah, I read that article... I'm not too concerned with it. The author of the article did'nt say so but I think the truck (2004) they were using had been subjected to some out of the box sloppy tuning and lack of maint. Towing with an out of the box (canned) tune with no pyro installed or no respect for egt's could bring about head issues...

I'm glad you guys dont feel theres a big problem with the valve seats. I was worried cause at some point I want to put on some studs but I plan to do it one at a time to save on the down time of my truck. If there was a big problem with these seats I was thinking I'd end up learning more about working on a 6.0 than I was planning to. What is the worst thing about pulling the heads off completely anyway I was thinking the injectors would scare me the most don't want to mess those up. but then theres the push rods and rocker arms but from what i've been reading it doesnt even look like they have adjusters you just bolt them back on. Is that right? well thanks for helping with keeping from being to worried about the valve seats.

yes its a known problem...90 percent of 6.0s that do headstuds have cracked heads... problem is hardened seats dont even solve the problem always...couple of guys on other forums have cracked hardened ones...So yes guys its VERY common....ive had two sets of cracked ones myself (first time i did studs and when i tore it apart this year to build the motor they were cracked again)

Yep, it's VERY common, but never checked when a truck is brought in for head gaskets. Even the 6.4L guys are having problems with their cracks... Or cracks in their heads...

But the question is, do the minor cracks cause a performance or reliability issue? We have done quite a few stud jobs (60+) and have only had 5 heads cracked to the point that they were unusable. Most of the time the heads have to be replaced because of fuel in the coolant in my experience. fwiw I'm no expert just a greasemonkey

Almost all the ones I have done are cracked between the glow plug hole and the valve seat. Most of the time replacing the injector cups takes care of the fuel in the coolant.

the 6.0 heads can crack and it can happen anywhere on the head. that is why the heads need to be checked before being reused.
