I thought I would start a continuation thread from my previous to update those so helpful in the past thread please read and comment for help needed.

After getting time to perform the compression and vacuum testing here's the results and I appreciate your addition advice on locating actual problem for repairs:

Vacuum:

At idle 650 rpm = 8.5 inHG steady
At 1000 rpm = 10 inHG and steady
I held the RPM's at several levels and the vacuum increased with rpm's and held steady in each case with no fluctuations at each rpm.

Compression:
1 cyl failed...
Tested each cyl 2 times to verify repeatability and values after 4-5 strokes.

7 cylinders = 175-180 psi
1 cylinder = 88 psi (Cylinders on pass side at front of head where noise the loudest.

Any and all advice appreciated now that we have some real numbers to work with, right?

Can we determine if this 1 year old bottom rebuild is okay and it's in the top-end only or what?

Thanks.
