Routine oil change and FWF inspection, expected no issues...
But the compression test; 74-78/80 on others, cly 2 50/80 first few tests, rotated prop several times, got up to 64/80.
Late night did not listen for source of leak, but did take the time to scope with new Vividia VA-400.
Other info;
490 hour since new IO-360M1B
Always 100LL
Exxon Elite 20W-50
No fuel or oil additives
Engine has not missed a beat.
Runs smooth even in LOP cruise operations
EGT and CHT normal ranges and matched close.
Plan of acction:
Listen for leak, expect exhaust.
Remove rocker cover to perform rocker arm/valve stem tap to possibly clear some carbon.
Add Mystery Oil???
Test run, lean.
Run compression test again.
More aggressive leaning during taxi operations.
Any further advice, additives, oil choice or observations?
Thank you.
