had a problem of oil pushing out of the filter on my endyn can. decided to pull the pistons and found that both compression ring overlap each other. what can cause this?

 

Rings sometimes spin on there own. I doubt that is your problem, however.

 

the ring compressor wasn't on right i guess when they put the pistons in.

care to elaborate some more earl? would appreciate it.

 

The "ring gaps line up and I have no compression"is wrong and just doesn't make any sense.Pressure or vacuum doesn't need line of site to equalize.It will go around a corner nearly as fast as it will travel in a straight line.

What Glenn says is very true and somewhat negates all the stress on where you place your gaps at. Rings can move on the piston based on how round and how tapered your bore is, as well as the rpms you turn.

 

You *probably* did it when you installed them - depending on what kind of compressor you used, they're really easy to spin around. BTW, which kind did you use? I orginally used the cheap one you tighten with an allen wrench and ended up getting my number 1 rings inline - blowing oil out of #1.

Finally pulled the piston and bought/used a much better ratcheting scissor type ring compressor. No problems since.

thanks for clearing that up, guys. btw, used to pull 8800 and no prbslem and then went up to 9400 then it happened.
