    Persistent P0307 (also a P0420)

    Check this intake gasket by #7. I had persistent problem with the 420 lean. With engine running spray carb cleaner and look to se if it’s sucked in at the gasket Sent from my iPhone using Tapatalk

    Power Steering Fluid Reservoir -- Replace?

    Yes. The nut where the high pressure fitting is comes off. One you remove that fitting it will come apart with coaxing. Sent from my iPhone using Tapatalk

    Power Steering Fluid Reservoir -- Replace?

    If the pump is fine replace that reservior. That corrosion is a ticking bomb for failure in my opinion.

    Battery Acts Dead but tests Good

    Unless they did a true load test it’ll check good every time. YMMV Sent from my iPad using Tapatalk

    Amsoil

    Inexperience will do it every time. I was just commenting on the total destruction on the inner race of the bearing. In the discussion the most likely caused due to a physical defects. Oil is the lubricant, coolant and carrier of debris since it isn't filtered. Once compromised the debris will...

    Amsoil

    I don't believe that is oil related imo. There was a small imperfection and no matter what was in that diff damage was already done. the damage grew larger with use and time. Late model GM pinion bearings seem to fail quite a bunch.

    Low engine temp on cold days

    With below temps put a piece of card board in front of the radiator. Works great, remove when it warms up.

    Broken Motor Mounts

    tbqh GM doesn't give a damn because if they did these issues would have not happened. My 2004 was bulletproof and the jury is out on my 2013. Only time will tell. Good Luck.

    Rear diff pinion seal - replaced and now it's leaking more!

    If it has high miles could have a groove wore in the yoke. If so replace the yoke or put a metal sleeve over it to repair it. Sorry I can't remember what they call them. Also make sure that nut is tight. I had a new seal leaking after a few days on my GMC truck. I replaced the seal and made it...

    Annual oil changes

    Darn Straight. I change it when the oil sample tells me so. 2007 Tacoma ASM 5w-30 15 months so far just a tad over 5K on the oil.

    Drop in oil pressure

    10 psi per 1000 rpm was rule of thumb on oil pressure

    Another oil pressure issue.

    Where was the ground hooked up for the stud removal part? Just curious.

    Temporary low oil pressure - is this different than what others have seen?

    Sounds like a stepper motor in the instrument cluster.

    Trans fluid flow direction.

    Usually the lower line at the rad is the transmission "out". I don't expect GM changed this pattern.

    Light knock when first starting in the morning

    Piston slap is my guess and it happens on high mile engines of this type.

    Sounds like Rod Knock smh

    Sucks man. Now you have to decide which way to go. Rebuild the one you have or a low mileage pullout from a wrecking yard.

    Sounds like Rod Knock smh

    Do you have any metal flakes in the oil? pull the dipstick and check. Sounds like a lifter as it doesn't go away under load.
