  • Valve train

    Please tell me I'm not the only one to do something stupid.....
    A few weeks ago my oil pressure gauge stopped working, I had watched it slowwly start sticking and then fail out right, or so I thought. I did take the precaution and ran a pressure test with a hand held gauge and found my pressure to be great, why wouldn't it be, I only had 9k miles on my 2004 3.4L right? Well, things change. Runnning to work in rush hour, every once in a great while I would smell burnt oil, I always thought it was Cleveland or somebody elses car, not mine, no, mine's clean, no leaks. Well, I was wrong. One day I ran to work, 50 miles one way, I get off the freeway to listening to everyone of my lifters tapping away. My shop was only a mile so I limped her there, popped the hood, checked the oil, ummm, what oil!? 4 quarts down. Oil pressure sending unit had failed and pumped out the oil. So I get a new unit, fill her back up, and I got one real nice lifter tick. I still think if it wasn't for running full synthetic valvaline oil i would have really killed the mill. Well, the tick lasted for 6000 miles, and got worse, last night it sounded really bad, bad enough, I shut her down, and towed her to the shop.
    So I call the parts store, I like napa, no listing on lifters for that motor.
    So I call the dealer, they ask me for the 8th vin.....
    Its a 95 acheiva with a bone yard '04 alero motor, now what do I do?
    No vin, bro, so how many lifter options can there be? A 3.4 is a 3.4, right? Well not according to the dealer, 6 differant lifters! So now what? BEN!!!! You all ran into this yet?
    I tear her down tomorrow and see what all is gone, I hope the cam ain't wiped, if it is, well there's an excuse for a mod.

    A "true" High flow converter, straight pipe.
    Low/No flow EGR valve, block off plate.
    Carbon canister and purge valve mod, place in large 30 Gallon can, cover, and place curbside, the city will do the rest.
    PCV valve and vent tube, reroute to exhaust to dump where it belongs, on the ground. Or add breathers and let it all free.

    Check the description of each lifter and you should find the right one. The alero could have come with a 6 cyl 3400 or the 2.2 Ecotec. So make sure he narrows it to the V6

    1990 4Door, 3.2L V6 TBI, 5spd manual. 4X4. Trooper

      they shouldn't be different at all, but go with the '04 Alero listing anyway.

          I tore her down today. Um, its not the lifters. All lifters looked great, the motor looked cleaner inside than outside, like brand new glass beaded aluminum. The whole valve train looked great. I have a bad feeling that its a wrist pin or piston.
          I'm pulling the motor out later this week.
