I think case savers and divilar studs can be a fairly permanent cure for the magnesium cases....as long as the heat is reasonably well controlled. I understand that this became a problem when the displacement grew from 2.4 to 2.7...more stress on the mag case and less material around the spigots...combined with more heat. Some of the 2.7's had a fan with fewer blades in an attempt to reduce fan noise. Another good thing upgrade for 2.7's.
When Porsche went to the 3.0, the cases were again made from aluminum and stud pulling is rare...but the early divilar studs were prone to corrosion and breaking.
Full Version: Exhaust or Head Leak?
It's done!!!
Went to my mechanics place to check on things and he is finished. Took the car out for a quick test drive and it runs really well.
Sounds like how a bad ass six should. This thing is fast.
Apparently the head leak was screwing up everything. Even the 46mm carbs seem alot more agreeable.
I hope it stays together for awhile.

A six always runs/sounds better than a five. Here's hoping it will last. Enjoy

I would ponder and say WTF, but I am just glad to see it torqued up and is holding. that is a GOOD sign!
