    My 04 ENVOY 4.2 sounds like an old man getting up in the morning

    I just replaced a fuel pressure regulator in an engine that when started fast idled briefly and then died. Pull the vacuum fitting and check if there's fuel in the line........ I also replaced a map sensor in a different vehicle that had exactly the same symptoms.

    New Lower Control Arm, strut bushing position?

    Measure distance from the strut to the control arm with the OEM bushing and compare it with the new one. If there is a difference that may indicate that something didn't go in right.

    Difficulty removing clutch fan

    Sure you can remove the thermostat "heat motor" from the housing. I believe it was a push and twist as you suggested. At least with the 4.2 it was...

    How much oil pressure is enough?

    My electronic gauge occasionally flashes 0, but I think if that were true I would get a low pressure warning light from the switch. There's no change in engine sound when it happens. Lousy accuracy of a fine chinese instrument I guess????

    Better fuel economy

    Inflate your tires. If you follow the factory recommendation, you will have best ride quality and worst fuel economy. Look at the sidewalls and see what the maximum is and keep it a few psi below that.

    Any one using this I6 Trailblazer Plug and Play Fan Kit from PCM OF NC?

    I really would like to hear someone do an efan install successfully. I converted an old Pathfinder to efans and drove it for years without any issues. With this platform I'd want to have the pwm variable speed and feedback signal working. I have a set of Ford PWM controlled fans that might...

    4.2 keeps losing oil pressure

    Same here. Sometimes I notice a faint knock, but it goes away when the engine warms up. What readings would a new 4.2 have?

    04 trailblazer, brakes dragging after new pads, calipers, master cylinder

    Were the calipers new or newly rebuilt? If they cut corners on the rebuild and reused the original pistons - that could be the source of the problem. The phenolic resin pistons can swell with age at the outer end. When the pistons are pushed back in for new pads they can stick. My cheap brake...

    Best seal puller for front differential

    I used a slide hammer with the right angle attachment. Should be included in the kit.

    4.2 keeps losing oil pressure

    My hot idle is at around 10 psi. I think I'll try draining the oil, and soaking with chem dip (filled through the dipstick tube). Then I'll drain that and pour a gallon of gasoline to rinse out the chem dip. The gas can be recycled in the lawnmower. After seeing the photo of the sludged up...

    SOLVED! CV axle will not budge

    FYI A 3 pound slide hammer is not heavy enough. You need a 5 pound or heavier one.

    what causes hub bearings to fail so often ?

    I tested this. With most of the metal parts that retained the bearing cut through, it still took nearly 20 tons of force to push apart the hub. So you would need an industrial duty impact gun and deliberately overtighten it to risk damage. It is a very complex and precise manufacturing...

    Talk me down from buying a s10 Blazer wheeler project

    The 4 cylinder engine pretty much kills the idea. Really gutless........
