Thanks for the reassurance Tony.

In the worst case scenario where I cannot get it out. I'm assuming I can find a shop that can do it for me somewhere.


Matt,

I am doing my 15th engine rebuild and had encountered stubborn cylinder head studs maybe 3 times only. I usually do it without heat and could get them out around 30 mins. But with a stubborn stud, additional heat is needed. Apply heat for 10 to 15 mins. on the spigot using a MAP to melt the bond between the stud and the crankcase. If my memory serves me right, I have removed more than 150 Dilavars head studs. About 4 dozens or so Dilavars studs are saved in my garage.

Using a Snap-ON stud remover and a strong impact wrench are my primary tools which I learned from Tom Butler.
