I'm Awesome
I have some Gibson shorties I want to install on a 1998 5.7L Vortec. Gibson instructions say very specifically to remove the manifold bolts only with the engine cold using penetrating oil. 1A Auto has a good video where the mechanic says to make sure to run to operating temp before you loosen else you risk breaking the bolts. Which is the best way? I could see Gibson wanting to limit liability by warning not to work on a hot manifold. But then I have Aero-Kroil which has previously worked wonders on seized bolts in the past and may work just as well here. I just don't want to deal with broken bolts so thought I would post the question to those who have done it before.
