Mileage #s are wrong due to my error. All new timing chains, cam sprockets, idler sprocket and bushing, crank sprocket and bushing, guiderails, and tensioners went in at 181,854 miles along with this fill of conventional Pennzoil High Mileage 5W-30 and Toyota oil filter. Therefore, miles on this OCI were 2,767, primarily highway use.
Vehicle history: bought cheap at 164K miles last year from original owner, chronic check engine light with error code P0016 due to elongated #1 chain caused by poor maintenance, average 22K mile OCIs.
Not shocked at the increase in iron & copper with all the new metal components, and silicon is likely from the huge front timing cover which uses form in place gasket (FIPG) sealant in lieu of an actual gasket...nearly 1/2 can of Permatex Gray Right Stuff to lay the 3mm-wide beads in accordance with the shop manual.
Interestingly hefty shot of Calcium in this oil. It had Rotella T6 0W-40 from March 18th until the timing chain kit went in.
It's been refilled with Pennzoil Platinum High Mileage 10W-30 and will get a Blackstone report when changed.
