| Yellow,
I agree with Shazaam!
Could be the OPS but it's definitely worth getting it checked out.
My old 748Bip had these symptoms at 6.5k miles. 200 miles later the engine went bang in a big way. Main bearings had failed.
Most dealers can do a pressure test for you. It will show the signs that you can't see hear on your own.
Better to be safe than sorry. |
