First oil change today at my friend's shop (60k miles on odometer) - thanks to everyone for the helpful info in this thread and elsewhere. Not quite DIY - it was a slow morning so the two regular mechanics there did a fair amount of the work with me after they put it up on the lift (that's just how they roll).
Installed the ezdrain valve from Jowett (still waiting for the billet filter housings to come back in stock). We couldn't figure out how to get a crow's foot to work on the valve body for a torque wrench, so we used the finger tight + 1/8 turn recommendation from the ezdrain instructions. It was probably a bit more than 1/8 turn to my eye, but I deferred to Mark the mechanic who was doing the wrenching on the valve and who does this for a living.
Several of the skid plates had to come off to get to the grease zerks on the prop shafts...also helped to put it in neutral so that we could turn the shafts by hand. The small removable portion of the front skid plate was missing. Another happy surprise with this CPO purchase.
The mechanics, who do this stuff all day 6 days a week (not on LCs, admittedly, but they see plenty of the 5.7 V8s), didn't want to drain the stock filter housing before removal - "it's plastic - they break - just take it off all at once". So, I let them have at it. It made a big splash, but their pedestal oil catch pan caught everything just fine. The new TRD oil filter we installed was square (thanks
@bloc) so no problems there. 8.5 quarts of Mobil 1 had the oil level just a hair above the upper mark on the dipstick after running the engine for ~30 seconds to fill the filter.
Engine air filter and brakes/rotors were replaced 3 months ago as part of the CPO process, so those were skipped, as was the tire rotation (recent flat => changed tires on rear axle; will be replacing wheels with TRD BBSs and three more new tires shortly.) Cabin air filter was also new from April, but the recirc door / flap is broken, so that's the next project.
The underside of the LC looked
very clean for a northeast US 60k mile late 2017 manufacture vehicle. Positively shiny in spots, only slight rust on the welds. I was very impressed. I removed the KDSS skid plate to find that the valve body is heavily corroded, as expected. I left it off and sprayed some penetrating oil on it, but did not fool with the bolts while the suspension was unsprung....will be trying the bolts when I can find a cooler, dryer day with some level ground and a creeper / big ole piece of cardboard.
Need to get the front positive camber dialed out, but will do that after the new wheels and tires. Anything else I should do or check? The maintenance schedule calls for "Re-torque propeller shaft bolt" - what bolt is that? Is there only one?
