Need some pro advise....

In all fairness, it was threadlocker red into cast iron. Someone assembled an engine with it all over the main bolts. Ended up ripping the threads out with the bolts, which probably about had it at that point. I don't even think Id try threadlocker into aluminum. I don't think I've ever needed to honestly.

I just tell folks to be mindful if they need to service something later on before they use locktite, or people will put that red stuff on valve cover bolts.

I don't know if those bolts are torque to yield or not, but being that they are suspect, I'd replace them anyway. Last thing you want is to find out they were overstretched when you twist the head off of one. Eww.
