MS360 NO COMPRESSION
« on: June 20, 2017, 12:08:29 pm »
I have a MS360 with no Compression.
Added oil to cylinder and it came up.
When I took it apart I noticed something i have never seen in an engine before.
One end of the bottom ring was "peened in" with a punch mark.
Is this normal?

Should have 2 pins in the ring lands where the ends meet. Missing one? Might be what did that to your piston or a cir-clip come loose.

Oh thats a pin? Looked like a punch mark to me.
I think all thats wrong here is the rings are too tight in their grooves.
Any suggestions on how to lossen up the clearance? I worked the lower ring around a bit and its much better not having much luck with upper ring.
Any opinions on the condition of the cylinder?   

Thanks
