You're correct Amber Gramps... the Vertex 'upgraded' aluminum housing is VERY poorly designed. And for the price I paid they will be getting an earful from me. If my original housing wasn't so badly cracked I would re-install it and send back the Vertex version.

I've definitely learned a bit more about Porsche engineering and a lot more about my patience (or lack there-of) with this little project...

sounds like you will be wrapped up soon though.

You also need to make sure your Top Dead Center Mark is correct and not off by 5°.

..,..and sorry I was such a dick. Some sellers get under my skin. It wasn't you.

and HA!... didn't take your comment as 'dickish' to me necessarily... I've followed too many helpful threads from you to think that ;-)
