Taking cab off to change head gaskets - Diesel Forum

diesel_doctor · 07-30-2005, 03:28 AM

A lot of shops are pulling the cab instead of the motor to do head gaskets. Anyone try this yet?

I don't think either has to be done to do head gaskets. I found one of the best tips I have ever heard in one of the recent threads. Somebody mentioned dropping studs in the bolt holes while the head is off the motor. Then you use rubber bands to hold the studs up so they don't drop thru the holes when you lift the head That way you can install the head with studs without removing either ther cab or motor.

why would you remove the studs? the idea of using studs is that they torque more acuratly than bolts. any stud use i have ever seen keaves the studs in there.

i have seen the front end removed in one piece for major engine work or engine swap.

Go to www.flatratetech.com they have a fair amount of info there. Thats how I am gonna do my 6.0 since it is a regular cab. Not sure I would do a crewcab that way though cause part of the interior has to come out to get the middle cab bolts.

no, sorry about the confusion. That is not how I meant for you to take that. What I was talking about was if you were to do a gasket swap and install studs at the same time. Granted if the studs were already installed previously you may or may not want to take them out to do a head gasket. This is just a way to do the job without removing the motor or cab.

my truck was just finished friday, the core support was removed, but not the hood or fenders, the head's were removed while the block was still in teh truck, the head's with the stud's rubber banded on them were re-installed in the truck. there was room to work, and get even torque on all studs.

and it doesn't puke on demand anymore [img]/ubbthreads/images/graemlins/biggrin.gif[/img]

New to the 6.0 so sorry for the dumb question. Why are you pulling the heads on your trucks?

HeavyAssault · 07-31-2005, 08:55 PM

Under power headstuds will "strech" and allow the cylinder pressure to blow into the coolant passages, thus causing the truck coolant to "puke" out the overflow container (I should have the basics correct). You should replace the head gaskets after this due to an increased risk of it happening again.

While there are reports of this happening on stock trucks, this is not a common occurance.

The warranty claim was $2,207. There are several misc parts and fluids (oil / coolant) that need to be replaced when doing gaskets / bolts. </font>

What HP or mods are causing the heads to have problems? Are the 05 doing this or has Ford corrected the problem? Thanks
