Hello All,
Got a second hand Husqvarna model YTH24V54LS Riding Mower, check out the cylinder wall and piston blemishes. Sorry, not sure if the blemish location in the cylinder. Engine is a Briggs and Stratton
in the #1 cylinder, taken with a bore scope camera through the spark plug hole.
Was wondering:
1. is that a scratch or crack.
2. not sure what that brown spot is.
Any input will be helpful!
Thanks,
Doug Lee

The first picture is not really a scratch it is the discoloration of the cylinder wall that lines up with the ring gap. The brown spot may just be oil sitting on top of the piston.

I don't see anything alarming.
What issues are you having?

Hello All,
Thanks for the quick reply!
Also found about 6-8 crankcase bolts loose. The previous owner said it was leaking oil past the shaft seal,
so oil consumption of some kind . . .
I think it was leaking past the oil pan . . . time will tell.
Thanks,
Doug Lee
