Just a quick question ! I have a AS41 case basis of my 1916.
Just removed the oil press reflif valve spring and it measures in at a 75mm/ 3 inch al but a 1/32nd ! is this too long ?

The othre one comes in at 1.5 inch.
Just checking is all

matt i had mine out for a sender replacement it was about that long i didn't measure but easy 7cm+

i just messured mine today and its just under 3 inches free length and .9 of an inch compressed , but not sayin that its the right length, i just blew my oil cooler and the spring might be the cause, dont forget its not just the length but the tension , the book says 17 pound and my spring feels morte like 50 pound, and thats on a 3 week old 1916 .

blew your oil cooler gees ! measurments about the same. nevr did check the tension tho !!!
