a popular engine brake referred to as Jake Brake was invented by Cummins. however his first prototypes were machined at Jacob Drill chuck company. and thats why they became know as Jake Brakes. an article is attached. gonna try this on a ford/lehman 6.2l inline 6. but superimpose over any other valve that is being activated within the compression stroke timing....still researching. hoping to get this done before i retire though. 108-jacobs-engine-brake-retarder-1957.pdf

What's the load in those?? Cork?

Gonna try on my lines tonight or tomorrow. Hope this helps
