Greetings one and all,
First time posting on here but have used the already written knowledge to great contentment.

I have an A65L 1971 OIF to which I am running up against a problem with the rings. Have already searched this fine forum but cannot seem to find the exact answer.
For years I have built many engines from large to very small and have obviously come across all the different designs of rings.
This time however, I removed one piece oil scraper rings, the replacements are the modern Hepolite with the coilwound expander.
I have fitted these many times before in larger engines with no problem, but it seems to take a disproportionate amount of pressure to compress said ring.

Am I correct in thinking this ring will have an extremely short life or have others had experience of these?

Have tried to locate the single 'unhelped' ring but seem to be having a problem located in Kent UK.

Those 2 piece rings do require a fair amount of effort to compress but in my book they do a better job than the one piece jobs.
As long as you gap them first they are OK.

Thanks for the reply guys.
Just for reference I did get in contact with SRM and they recommended the rings made by Hepworth as they are cast iron without the expander ring.
