I'm just terrified that I'm going to blow this up so I need to do it the right way.

I think I did it right. Tried to keep everything as clean as possible. Rubber gloves and brake clean were flying everywhere!

What is all the white stuff that you have on the main bearings and caps? Assembly lube of sorts?
Are you replacing the crank sprocket? You had mentioned that it was rounded.
Looking good!

Assembly Lube
My project of the weekend is to get the new sprocket on.

These two inverted torx bolts that secure the lower cover on were finger loose. No wonder I was leaking oil.

Jesus bolt out.
Stretched as I thought. If you didn't read it earlier the bolt was easily loosened by a big pair of channel grips.
@DrLeadFoot

Any advise to get the middle torx bolt on the timing case cover loose without removing the cams?
@DrLeadFoot

Still trying to find time and motivation to get in the garage.
I was thinking about not using the metal gasket on the front cover and just going for the Ford black atv sealant. In order for Kummrow to stop the leaking I had to ask them to ATV seal all gaskets.
I will be ordering new exhaust vanos sprocket bolts just in case the old ones are stretched out like every other bolt has been so far.
That should be it for parts then I just have to get my ass in gear!!

I have it on vacuum via the exhaust.
Have you turbo'd one before? I guess they leak pretty bad from the crank case pressure.

So it isn't a vacuum, just a low pressure, it attaches post turbo right? There will still be some pressure. I am not sold on this setup. Why not just a catch can vented to atmosphere? I understand that you don't want oil going into the turbo inlet so this would be the next best thing.

My crank case set up goes from the valve cover vent--->catch can--->exhaust vacuum.
If you pull vacuum from the crank case it makes more power from what I've heard from drag racing / turbo guys.

I see a lot of people running the crankcase vent to the exhaust. I have mine run to a catch can then to a port just downstream of the air filter.
the turbo inlet is completely dry and oil free and the catch can is doing its job. So far so good. Not sure if its more of a concern on a 24v though.
