Upper head bolt question
Posted by: Grandpacorvair ()
Date: November 29, 2017 05:56AM

when trying to remove the upper cylinder head nuts is it 'ok' to use vise grips to try and prevent turning the stud? Concerned about the inevitable scarring that's going to happen using this approach...

currently soaking nuts with alternating PB blaster and WD40. Will do so for several days b/4 making first attempts....

Yes, its been done often, better a little scaring than having them twist out.

After trying everything I could think of plus help from the group I went with this.

Vice grips on the studs gripping them between the cylinders has been a standard practice here in Dave's Man-Cave.smileys with beer

I never worry if studs come out or not. I use my 1/2" impact and either the nut comes off or the stud comes out. If the nut stays on the stud I then clean the threads top and bottom smack the flats of the nut a few times, put the stud in the vise and turn the nut ON! I then clean the stud threads all the way and spin the nut off. When everything is cleaned and ready to go AND if the threads are good then the stud can go back in.
