Congrats on the new diesel driver addition to the family.
My two are at at The Farm in Palo Alto...hence I drive ancient MB's...and love it!
The job is maybe 30 minutes, just being careful which spec goes on which valve. I had to bend a couple $4 combo wrenches to nest just right, but after that, the job is straightforward...and very rewarding.
