Does anybody have a copy (.pdf) of the Lycoming Service Instruction No. 1316-A describing the process of resurfacing the vernatherm seating surface that they could share? The dual-mag engines do not have a removable oil-filter-adapter and I'm trying to determine whether the seating surface can be touched up in place without risking contamination of the engine (perhaps by flushing out the filter-adapter and oil-cooler lines from the vernatherm's opening).
Please don't ask me to search Lycoming's website or do a Google Search as that has been unsuccessful. If you have better luck and can provide a direct link to the SI then I will offer you great praise.
Thanks in advance...
