Long story short my dipstick from sikky header install has had a leak. I finally have an opportunity to fix, and was wondering what all is entailed in the swapping of the oring besides draining the oil. The Lexus dealership is charging $400, which initially seems excessive, but that is before understanding what it takes to perform the procedure.
If anyone has any information on what it takes please let me know, so I can figure out whether I can do or not, and/or whether they are justified in that rate to perform the o-ring swap.
