Thread: how can i tell

Tweet

I was just wondering if how you tell tell if piston rings are installed backwards? I heard that they will seal at first and then stop after a while allowing gas to get past them. Is there a way to find out with out taking apart the engine?

thanx

Nope. I had a ring installed upsidedown in my dirt bike. It smoked a lot for about 30 seconds after starting it, but that was it. The cam timing was also off by a tooth, that was my fault.

if you have the top ring on backwards i would think your comp. would be low and a lot of blow by. if its runs good and has good comp. i'd dive it.

thanx for the info guys
