    LBZ Block worth?

    I have an LBZ block from when I converted my truck from LLY to LBZ over a decade ago that's just been sitting in the garage since then. The 'original' plan was to built it and then swap in with the existing LBZ top end, but you know what they say about the best laid plans of mice and men. It is...

    2015 Malibu (and others) connector type/de-pinning

    Does anyone happen to know what type of connector the X1-X4 connectors the ECC control module on a 2015 Malibu, among others, is, and what kind of tool is required to de-pin the connector? I've exhausted my resources and cannot find any details on these connectors, and haven't been able to...

    2007 GMT900 Silverado 5.3 P0191.00

    A friends Silverado has been kicking our butts with a DTC in the ECM that I can't recall stating that the FPCM has issues (Similar to the TCM's P0700) and FPCM P0191 00 and recently also a P0192 00. The parts canon has been fired but the issue still is present, and it seems to be somewhat...

    Another Non-Duramax question - 2011 Aveo

    I have a friends 2011 Aveo, which had initial symptoms of it just died and they were able to jump it for a bit and then couldn't - this sounded like an alternator issue, and when we went to retrieve it from the side of the road, the battery (only about six months old) was at 11.8v, although it...

    Not Allison rebuild question

    First off, this is not about an Allison, but I imagine that most transmission experts like Mike knew a LOT about more than just one transmission. That being said, hopefully some of the experts here are familiar with Ford's 4R70W and can give me some pointers. I have a 95 Cougar, that currently...

    Vehicle fuel/maintenance log software?

    Does anyone know of any good fuel/maintenance log software? I found 'Simply Auto', which seems pretty good, but what I'd really like to find is something that has an android and PC version, that can sync to each other, WITHOUT 'the cloud'. I don't want my data uploading to 'the cloud'. Ideally...

    Non-Allison - Mike or Evan know anything about a 6T70?

    I know this isn't Allison related, but Mike Mike and Evan are the most trusted 'go-to' people for transmissions, so hopefully one of them knows something about the 6T70 transaxle (I THINK that's what's in the car, I haven't been able to definitively confirm it... it's almost certainly a...

    Any home A/C experts here?

    Have an issue going on with the central air in my house. I've noticed that recently, ti'll cycle in the through the morning, then around mid day, it'll come on and not shut off until 3-4am or so. Checking the temperatures of the return and supply, there's a 15* or so degree difference, but I'm...

    TPMS problem

    I just got new tires and replaced all of my TPMS sensors as one of them was starting to flake out, and I've got an issue with them. I ordered the AC Delco 'TPMS173K' from Rock Auto, which appear to have a pretty broad application chart. Fords, Hundais, Kias, Nissans, Chevys, etc. I set my...

    Seemingly odd noise from 01 Allison

    I've had my step-father's 01 Sierra ECLB equipped with the 8.1 and Allison for a few weeks, and I just noticed an 'odd' sound, seemingly from the transmission today. I was sitting at a drive through, and I didn't really 'notice it' until I put the truck in neutral and it went away. The best way...

    6T70

    Mike, do you, or anyone else here happen to know anything about the 6T70? My wife has a '15 Malibu 2.0T with the 6T70 next to it. Ive been noticing that it seems to start shuddering when you get onto the throttle, usually in the lower gears it seems. Does this sound like a common issue, and is...

    #@%$@#$ Tree Rats!

    So for the FIFTH time in the last two weeks, I have had to remove a yardfull of leaves from the top of my engine bay that was put there by POS tree rats - the first time they chewed a bunch of wires so when I jumped in to go somewhere, it didn't want to start, and when it did, it sounded like it...

    Weigh Station question

    I know there are some here that haul commercially and are likely familiar with weigh stations. My understanding of them is that they are meant for commercial drivers hauling for commerce or other commercial reasons, and that if you're running personal, you don't need to go through them. I made...

    New 'vibration'

    Traveling out to NY last week pulling a small trailer, I noticed what seemed to be a new vibration, somewhere between 50 & 60 MPH. Coming home heavier, it was more noticeable, and I was able to narrow it down a little. It feels similar to when you're driving on rumble strips (But FAR less...

    LBZ fuel return o-rings

    Does anyone have a new, never installed OEM GM return line that you could take some good OD and thickness measurements in metric and imperial values? The Napa replacement kit, like other aftermarket kits, sucks because unlike the oem fittings, the aftermarket fittings don't have the 'wings' over...

    Does anyone have a part number for the formed hoses the run between the fuel filter head and the block at the test port on a LBZ?

    Gates Powergrip

    Anyone ever heard of these or used them? They sound interesting, and from a name like Gates, I can't imagine they are total junk, but at the same time, I have some trouble trusting a 'shrink wrap' hose clamp over a metal one...

    Front Diff Lift mod

    Has anyone heard of modding a front diff by cutting off the top mount for a lift kit? I got a diff this weekend to replace the one in my truck, and I didn't notice it until we were trying to shove it up into the truck, but there is no top mount. On looking, someone cut and ground the mount off...

    Injector fuel leak

    So I just noticed a nice puddle under the passenger side of my truck that shouldn't be there (And thought I smelled fuel a night or two ago) and upon investigation, I found that #1 & #3 injectors are soaked, as is the passenger side of the block, and fuel is dripping from the 1, 3 & 5 glow plugs...
