The bigger the better??

^^^Thank you sir!
What do you think about studding it without changing the gaskets Ryda?

 

[Sasquatch_Ryda]

I wouldn't take the risk.

If there is no issues with the gaskets now, leave them be. If it develops a problem worry about it then.

 

[COPPERHEAD85]

Thats kinda what I told him,thanks.

They try pulling it out like a magic trick...you know, with the table cloth on the set table...the mechanic leans over the hood, grabs a tiny edge of the gasket, and with one swift motion yanks the gasket out...

Now, to put a new one in...they just use that liquid metal stuff...and they apply it with a turkey baster...

Great example!! Thank you very much! And that method is retarded.

The 6.0 is actually a pretty good engine. The head bolts were a big problem at first, not enough torque, too much yield.

The turbos were problematic at first, but most of that was due to driving habits, and a lot of it has been fixed by teflon-coating the center.

The biggest problems we are seeing the the 6.0 right now is injectors going bad, and more recently heads have started allowing fuel into the cooling system. Not good.

1.) Very interesting.

It is fun work though. The problem now is that I have to decide, do my ribs hurt, or does my knee hurt when I get home.

2.) It sounds like at your job when you are not working, you are working to keep your job!

Guys trying to do head gaskets on these things in place with an impact. To do it properly, the engine NEEDS to be out and on the stand to torque them properly, in the proper stages.

Thank you. Also very informative.

No, you can torque the bolts in sequence, with the engine in the truck. You just have to have half of if in a pile in the bed, and it's an enormous pain. I have a 72" piece of pipe that I use over my breaker bar. It's still a pain.

No, I just have a bad habit of dragging the lift arms out with my leg. It puts too much sideways force on my knees and makes them hurt.

My wife yells at me for doing it, then turns around and tells our pastor's wife, who is a physical therapist, that I'm doing it again, and she in turn comes back and yells at me for doing that.

Well....each to their own. I know what I was taught and that's how every one of our 5 diesel tech's does it. No if's and's or buts. We re-do a lot of these 'done in place' jobs from other dealerships.

Local dealer does it in the truck, no problems in the 1.5 years my brother has been there, and they have had some fairly wild 6.0's go out the door.

Honestly, I'd probably rather do it that way myself, but the shop manual does say that it can be done in truck. I'm sure the results are probably better with the cab out of the way though since the 90's are supposed to be one smooth movement, and doing it in place doesn't allow for that unless you are the Incredible Hulk.

I didn't think pulling the cab was an approved method for warrenty?

 

[adsm08]

Nope. Cab-off service was not approved for the 6.0. It's downright required for the 6.4 and 6.7 though.

You can just pick the cab up a couple inches to get the turbo off on the 6.4 though.

They have been having a string of 6.4's they have ran out of coolant, got hot and popped the headgaskets and hydrolocked lately... lots of cab pulling for that.

We haven't seen that. We got one that blew an exhaust gasket in the back, and one that we bought at auction as a "Does not run". The previous owner had put a hydrogen system on it. Then put an engine in it. Then put the hydrogen back on the new engine. Then he cracked a head and just got rid of the truck.

It also had a dealer-voided warranty because his aftermarket stuff kept breaking the engine so he'd go from dealer to dealer until he found one that would do the job under warranty.

 

[85_Ranger4x4]

The radiators break, they run them out of coolant and get them hot. Then they dump in more coolant and the darned thing won't turn over.

Normally service/farm trucks.

I think they have had about 5 of them in the past 2 months.

 

[adsm08]

Wow. That sux.

 

[Sasquatch_Ryda]

We have done a ton of cab off jobs on 6.4's. Its gotten down to 2 of us having the cab off and the engine ready to be put on the stand in just over 2.5 hours.

As for the 6.0L...nope we don't pull the cab....we pull the engine and put it on the stand. And yes, it does make pulling those 90's alot easier during head bolt torquing.
