Oil ring install question
 

It's been a couple years since I installed rings and I'm sure that I knew this once....

When you're installing the oil rings (scrapers), I'm recalling that you flex the scraper rings and then install them either flexing up or down. The logic is that there is a little better oil 'scraping' one way or the other.

I'm pretty sure this was from HO Racing, but the memory is fuzzy.

Does anyone remember this detail? Or does it even matter?

Thanks all !!

Flex, flexing...? I get a rail end into the groove, and walk the rail on. Like an iron ring is put on.

That might have been true for factory rings but if that was needed to be done with aftermarket rings it would state for you to do such in the instructions, and it never does.

It’s by far more important to spiral rap the oil rails into place and for the other two rings use a dedicated ring expander.

Don’t forget to break the sharp edges of those rails and even the two top rings so you do not scrap up your cylinder walls and also to not inhibit the rings from spinning as they need to do.

Once grooves are in place the rings will not spin and then ware on the both the walls and the rings will be accelerated.
