Regarding dipsticks: Sprinter dipstick The late model V6 still has a dipstick tube that’s been plugged off.
You can still use an extractor, the tube plug can be removed & reinstalled.
Recently installed them on my RAM 1500 4x4 and am happy with them too. Nice road manners, quiet, and handle snow here in the Catskills really well. My only nit is losing ~2mpg.
2008 Kawi Teryx 750. A carbureted workhorse for my farm and the few parts I’ve needed are plentiful. I did upsize wheels & tires. The ol’ girl can do 45mph on the pavement here in the western Catskills.
