I am still allowing mine to soak…just haven’t had time lately, so hot these days here, and perhaps savoring my victories thus far with the A+ condition of block, bores, and head…
Iron is quite resilient…should be no problems heating that up well at the base. Heating red hot shouldn’t be necessary. Ok if only done a couple times…
However i would (and intend) to spray it down and cool first with lubricant prior to attempting to loosen.
Keep an eye on it below while attempting to turn so not to snap it.
Still not giving? Repeat ad nauseum. Doesn’t have to get red hot. I intend to heat only the stud end where attaches at block.
They should give eventually unless completely bonded.
If giving only a little, stop, and tighten again, repeat.
It’s what an old friend, the master mechanic at classic jaguar in Austin taught me as a kid many lifetimes ago (and different management fyi).
Always worked with everything and he knew his stuff. Has his own shop now i think.
Strange, i can still recall that smell as it evaporated. Funny.
Perhaps it was smell of victory!
Despite the condition of my studs (see my thread), and a couple down to pencil widths on intake side, they did come out without heat.
Haven’t done exhaust side yet, which although more robust, were really rusted. Bonding concerns me there.
Definitely intend to heat thos prior to attempting.
Also, i have been recommended kroil here and by those in the know who swear by it.
I intend to try it worse case…
UTube has some interesting vids for motivation if anything.
One needs it often times with these things.
Please update how it all goes for you.
