Head studs in and heads stayed on

[Agnem]

That sounds scary as hell.



I had to replace one bolt ONCE, at the end of a headgasket change out job, because the washer broke as I was torqing it. I'll never forget the sounds the head made as relieved all the tension there to replace the bolt and retorque it. Sounded like ceramic bricks sliding against each other.

You must have had nightmares for weeks after that. That sounds scary as hell.

How about an update, this still working?

There were lots of guys who had 6.0L trucks that done this exact procedure, just as a precautionary measure, and as far as I know none of them had any head gasket issues afterwards. There was such a big scare about 6.0L headgasket problems for a while, lots of guys swapped bolts out for studs the same way that the OP did and they had good luck with theirs. It was more of a piece of mind for them than anything.

I don't see why it would be a problem. It is really not much different than a proper retorque procedure where after X amount of miles you first release the tension on the head bolt then re torque to spec. On a re torque you must release the tension on the bolt first or you will get a false reading on the torque wrench while breaking the tension loose on the bolt. You only get an accurate reading while the bolt is in motion, so for that I don't see a whole lot of difference. Only difference I do see is in the tightening procedure on the stud as in the 5 steps ditty not being followed. I'd be inclined to go back in there and go after those critters another 4 times to make sure the final clamping force is where it was intended to be, and I'd do it in sequence one step at a time to avoid cracking.

It is still going strong

what have you took your boost to now? i know you said you hit 18 before the studs , have you hit 20 yet

 

[crash86]

Ive hit 19 cant push anymore out of her but its crazy that i can only get 12 or 13 without the propane but no problems so far knock on wood

 

[david85]

Any chance to see a video of that?

19 PSI must be so much fun it's sure to be illegal.

 

[Knuckledragger]

Sometimes the shortcuts work out just fine. Good for you!

I couldn't figure out how to get the head bolts off without pulling the engine (leading to an entire rebuild), but never thought about taking off the A/C condenser fairing. Good idea.

wow, you need to post some videos of that thing! i bet 19psi is fun!

I wouldn't mind seeing a video either, in my truck it doesn't seem like it makes any more power past 15 psi, maybe I am just worried about popping a gasket but when I am climbing a hill I can push upwards of 15psi, roughly ~18psi but it seems to pull the hill just the same if I let off the throttle a little and let the boost fall below 15psi, it makes me feel a little better too.

with head studs i would feel safe pushing 18-20 into a 7.3, but i guess thats just me

I may install my intercooler soon, and see if it feels like it makes anymore power beyond 15psi after that. Right now it just doesn't feel like it pulls any harder above 15psi though, I just worry I am putting extra stress on the engine for no reason.

yea i understand what you mean there, i bet when you put that intercooler in there it will be a hole different animal
