I understand the reasons for fitting alloy valve spring retainers, and the
advantages.
I also know that in the past, I have heard reports of failures of those sold
by Moss, dropping valves into the engine with obviously disastorous results.
Looking at what is available on the market these days, from all kinds of
sources.
I see many vendors merely referring to them as 'Alloy', which tells us very
little, whereas one calls them 'Aircraft Alloy' - still a very broad cover-all
term.
One calls them 'T6061', and yet another calls them '7075'.
These are both 'aircraft alloys' and the 7075 has a much greater tensile
strength than the T6061.
Does anyone have any actual experiences, both good and bad of using different
suppliers alloy valve caps?
If you do, then please tell me!
I am afraid that I have little faith in companies that do not give proper
technical descriptions of their products, especially critical ones, such as
valve
retaining caps and/or cam followers.
Thanks in advance for any help provided.
Best Regards
Lion
