WTB Oil gage rod and cap TCM PN 656616-3 (dipstick))

sounds like a good idea, Jim - might be less expensive than the $600 I was quoted (even though none are available). Send the company info, might do it.

Dave: I’m going to have to get a local engraver. The company engineer backpedaled when I reminded him that this was for an experimental aircraft. He said that he would help me, but that would be it, and asked me not to publish the company name, as they would not help other experimental owners. I’ll keep you updated, but will not be using that company. Jim

Is there a reason not to just punch some numbers and mark with a harbor freight punch? my older TSIO sticks were punched and I think the Legacy one is also.

I have the large capacity pan from AeroChia that someone was custom making for him (IO550N).
Eleven quarts is about the 6 quart mark on the dipstick. My engine seems to like between 5 and 6 quarts.

I use it like a most other engine dipsticks (ie, no numbers)- 6 quarts (indicated on the stick) being “full” and 5 quarts or so time to add a quart.

If I check the oil level and it would happen to be much below 5 quarts, I’ve likely got a problem that needs investigating as I don’t use much oil.

[Jim Anderson]

The reason for not punching, drilling, grinding, mechanical etching, etc. is the potential for induced stresses on the blade. I was told emphatically by the owner of a well respected Flight Service Station who overhauled my engine not to employ any of those methods, due to the risk of breakage.

It is a very thin piece of metal.
I wonder about indelible markings that don't involved metal loss.
I actually bought a new stick from Autozone to see if I could cut off the unmarked portion, then attach it to my cap but have set it aside for now.
