head studs

[woodsenterprises]

has any one had any luck doing head studs one at a time on the 6.0 i really dont want to take it all the way down

I think there is a few that have done it and been fine.

I asked the same question recently. Definitely debatable. Someone kept talking about torque patterns and never do it one at a time. Common sense says if you do this one stud at a time, to go in the order of the torque sequence. If you never break the seal of the gasket, you should never have an issue by swapping one bolt/stud at a time.

There should be no debate on this issue. I have been a diesel tech for 26 years, both light/heavy and heavy duty. in all that time I have yet to see any type of manufacturer service info describing such a procedure. you might get away with using such a procedure a time or two, but if you knew anything about an MLS gasket and have any experience with the 6.0 liter powerstroke diesel, you would not even consider replacing the bolts with studs one at a time. if you have towed heavy loads with your 6.0, or have dogged it at all, there is a high degree of probability you are already on the verge of head bolt/head gasket failure, even it it does not cause a problem right away, it will only postpone the inevitable.

So my truck is in the shop, under warranty, for a blown EGR cooler and Oil cooler. The diesel technician at the Ford dealership is going to install ARP studs and an EGR delete for me under warranty. Is he going to tear it all apart to see if it has bad headgaskets? He said he ws going to replace the EGR and Oil cooler and then he can tell if it has bad headgaskets.

What does he mean by this? I'm pretty sure it has blown headgaskets, as it has towed heavy loads it's entire 120,000 mile life. So how is he going to be able to tell if it has blown headgaskets or not?

I'm not sure how he is going to test it for a HG leak, there are several methods. if it is loosing coolant and the egr cooler passes the bench test, then it would be a pretty sure bet a HG has failed. I have seen both HG and cooler failure at the same time. the latest TSB -related to coolant loss, HG and cooler failure testing, hopefully the tech knows how to read and has performed steps to determine the cause, but it is not always cut and dried, sometimes we have to drive the meat out of them to get a failed HG to reveal itself, this is common in the early stages of head bolt/gasket failure. I always prefer coolant running out of the tail pipe, makes it easier, lol

if your going to install stud, spend the extra time to tear it down all the way and do it right, anyone who would do them one by one is asking for trouble

Haha wow, I had coolant coming out of my tailpipe lol! Here's what came out:

I told the service manager that it was puking coolant put the degas and the tailpipe when she was filling out the service ticket! Hopefully it is headgaskets!

yeah, most likely a HG. the dealer I deal with will do studs on a warranty HG repair if the customer supplies them, not sure how they get away with that? hopefully they'll do it for you.

I'm hoping it's a HG!!!!!!!

But the tech told me it was definitely an EGR and Oil Cooler fail, and he would install ARP's and an EGR delete if i supplied them

I'm assuming he knows its a bad headgasket if he told me to order ARP's??
