Toyota 1MZ-FE ~122k miles. Had valve cover gaskets changed, still slow leak. Indy mechanic says bc of shoddy gasket job by dealer when timing belt done at 85k. Anyhow, its full of Peak 5w30 conventional right now, topped off with a quart of 5w20 pennzoil synthetic I Think, due to dripping and maybe burning some. I have 5w30 and 10w30 QSUD, and some carquest synthetic 5w30 in the garage, as well as my standby FL-400s filters for it. ITs got about 2300mi on the OCI currently.
Id rather not go buy high mileage oil if not necessary right now. Also, I try to keep syn in this engine due to chance of sludge. OR run a shorter OCI if conventional.
To minimize the leak, should I try the 10w30 at next oil change? Is there anything I could add to maybe help the leak?
Thanks!
