Car didn’t pass inspection because of an exhaust leak.
So... Just ordered some manifold gaskets from Pelican Parts. Question is. Is this copper soft out of the box, or does it need to be annealed before install? Thanks for sharing your experiences. |

Helicoil won't hold. You need a timecert. Install once and done.

(IMG:style_emoticons/default/agree.gif) I use timeserts for M8 and up, I only use helicoils for M6. There used to be M8/M9 step studs but are hard to find now, even though they're standard equipment on new AMC heads. |
