Got the 560 back from the tune-up - mechanic said there was some oil carbon build-up on the spark plugs he removed. These plugs were only a year old.

He suspects valve seals.

He ran a compression test, gave me the print out - close to perfect on all 8 cylinders.

Next up - air conditioning!! Summer is coming.
