I haven't heard of anyone needing to adjust valve lash, especially at low miles. I have 117,000+ miles and never adjusted and no noise yet. The service manual says: "The 24 valve overhead system is a low-maintance design. Routine adjustments are no longer necessary."
Not saying you need not to adjust, unless something unusual happened to your engine.
By the way you do not have a "Jake Brake", it is a exhaust brake
, a totally different system.
Remember not to talk bad about farmers with your mouth full!
