The minutes of the May 11, 2005 teleconference were approved as issued. (Thanks, Jeff!!)

Wim confirmed that the main topic of this telecon is oil consumption changes in the T-11 test, and Riccardo described an experiment where he ran three tests for 120 hours each using the same oil and power assemblies but varying the valve guides and seals. The first run used "current style" valve guides with the p/n ending in B3111 and seals ending in C332. This run gave an oil comsumption rate of 44.8 g/h. Switching the intake guides to an "older" p/n ending in B3103 with C328 seals dropped o/c to 37.5 g/h and changing both intake and exhaust guides and seals reduced it again to 33.6 g/h. 
It was noted that the latest guides are p/n ending with B3113, and the physical design is the same as 3111, but the material is more robust.
Riccardo noted that even the best data was still more severe than his previous experience with this oil which was about 25 g/h. In addition, he noted that this is a "low consumption" oil - not TMC 820. His last reference with TMC 820 ran at 65 g/h.
Following some discussion what these data actually meant and what our options were to move forward, Jim Matasic made a motion to standardize all future T-11 testing on the B3113 guides and C332 seals. With a second from Scott, this motion passed with unanimous support. 
Jim Matasic gave an update on his current reference attempt which is running at about 23 g/h at 168 test hours with TMC 820. This result is on a rebuild using the top rings from the T-10 (or T-12) in an otherwise standard rebuild. (His previous calibration attempt ended up at 83 g/h) By group consensus, this is the lowest oil consumption rate anyone has ever seen with TMC 820.  Although the test has not yet reached the soot/viscosity break point, the data so far appears to be normal.
Both SwRI and XOM offered to run calibration attempts using these T-10 rings assuming the stands could be calibrated, if they met all normal calibration requirements. 
This lead to an extended discussion regarding how long this T-11 oil consumption issue has been apparent, how much data do we need to establish any potential correction factor, when the test will complete and whether we need to discuss the final test result before the next two tests start. Wim agreed to set-up another teleconference for Thursday, June 2nd at 10:30 am EDT.
Wim addressed several action items from the last telecon:
0) Ron Buck to look at parts measurements to see if anything predicts oil consumption degradation.
Ron reported he had supplied the data to Jim Rutherford, and Jim had circulated his analysis to the group (with a couple of exceptions due to e-mail issues)
Jim reviewed his analysis which showed some correlation to hardware, but an even better correlation to just time. 
Jeff agreed to update some of the data with corrected oil consumption for five tests, and there was a discussion that some of the apparent step change versus drift changes could be due to parts inventory management within labs. Ron agreed to supply parts kit/batch information to Jim so he can look at the revised oil consumption data versus hardware batches.
0) Labs had agreed to check consumption versus valve guides, and Riccardo's data covered this issue.

New action items - Ron Buck agreed to supply T-10/12 top rings to SwRI and XOM for their next calibration tests.  
Greg requested  that all of the rings from the first four T-12 tests should be identified as to location and sent to Ken Goshorn ASAP.

Jim Matasic noted that Lubrizol's T-12 had reached EOT yesterday, and Jeff Clark noted that there are two T-12 results on the TMC website. Jeff also noted that the T-11 test now has an official D number, D7156.
There will be a face to face meeting on June 20 in Pittsburgh, and there will probably be another telecon between the 2nd and the 20th to address T-10 lead issues.

Pat
