Valvoline Restore and Protect 2AZ-FE Observations & Questions

[50yr Street Mech]

Awww. No fair..Nice and clean. I got globs of oil on one valve. You never told me the year of the 2AZ-FE ???? I didn't know PEA could leave a mess on a piston head. Thanks for the heads up

Adding the PEA is the only thing I had done differently when that shot was taken. My 2AZ-FE is a 2006 which isn't supposed to have the ring problem, but I bought it used at 50,000 and don't know how it was treated. I've always changed the oil between 3-4000. It runs good. The Valvoline has made a difference in how it runs too, quiet cold starts, smoother idle.

I'm looking for the BG EPR locally. Maybe a shop can sell me a can. I can either wait out the 4 oil changes with the Valvoline (I'm sticking with it no matter what), do a soak with Berryman's, or try the EPR.

If it were mine, I would do a Piston soak at the end of current interval. Then keep running VRP and go from there. It's entirely possible that VRP alone will continue to improve the consumption. Impressive results so far, love seeing the before/after compression testing.
