Thanks all for the condolences. I am in the process of making a little ring to go around the outside of the #8 bearing. I got this idea from Walt. I quit working on it for today.

Ken, you know what look I had when I realized that it was the #8 o-ring. De-turbo-izing is this: The 3.0L SC engine was (years ago) not making enough power, so I put a turbo on it. But, when I rebuilt it the last time, I put 8.5:1 JE pistons in it, and it has DC-20 cams, EFI (I ditched the CIS a few years ago), and a few other things. Wifey didn't want to use the car because it has too much power. OK, fair enough. Not everyone wants scary acceleration. So, as I had kept the freshly rebuilt, 0 run time, 2.7 which was destined for the now gone 914 racecar, had Dema Elgin regrind some E cams to the Solex grind, and put that together. That is the long block that is leaking, since I built it 10 years ago. It was leaking at both seals, front and rear, and I pulled the engine out to replace those- this is after pulling the 3.0 out, and putting the 2.7 in.

Anyway. I made the 3.0 modular...I could take the turbo off, and it becomes essentially an SC again. I prefer not having to R&R the engine again (although I am getting pretty good at it). I'll post a picture of the new ring I'm building (in hopes of sealing the #8 bearing from the outside.

BTW, I did a leakdown on the 3.0 today...6% across the board, cold. Acceptable.
