Valve cover bolts

Riddler,

I've found that when threading a steel bolt into threaded aluminum it is quite easy to over torque the bolt, and after a few times putting something together and taking it apart the threaded holes can show considerable wear. If you show the slightest bit of care in your torque it isn't an issue, but if you get a little aggressive it is pretty easy to strip the threaded holes.

I use to do quite a bit of work on air cooled VWs, and with their magnesium case it was always better to use studs to help preserve the threads in magnesium. I don't know how many oil screen covers that I had to heli-coil because the holes became stripped out over time.

As a result, I would typically blue loctite studs whenever possible.

Regards,
