    Might as well do the plugs also since the resonator has to come off

    Then I need to change oil to Mobil 1 high mileage 5w30 and WIX filter.

    Probably check transfer case and differentials, swap out Mud/snow BFG Long Trail for the Mastercraft Courser ATX's for winter

    Don't those things have quite a few fuel pump failures?

    That was the S10 Blazer. The Trailblazer is the replacement though

    Somebody wrote 7 quarts with filter in paint under the hood.


    I have 15 quarts of Mobil 1. It was on sale at Meijer for $23, and a $12 rebate , max $24 rebate

    What year is yours?.we are possibly looking for a trailblazer or envoy.or a 1/2 ton crew cab P/U 1/2 ton.

    I am a born Ford guy but a full size Ford has that stinkin triton junk,overhead cam,spark plugs a mile down in engine.nuthin like a pushrod engine.

    The 4.2-liter Atlas LL8, otherwise called the Vortec 4200, was a groundbreaking engine for GM. It featured an all-aluminum construction, dual overhead cams with variable valve timing on the exhaust side, four valves per cylinder, a coil-on-plug ignition system, a high compression ratio of 10:1, and its cylinder heads featured GM’s then-prevalent “Vortec” engineering designed to maximize airflow.

    EWWWWW, dual overhead cam.I may just look for a F/S chev/gmc 1500,5.3 LS motor.
