    Oil Pressure Woes - Need Advice/Help

    That is EXACTLY what I needed to know! If they require positive pressure to collapse, they cannot collapse unless commanded. You rock! 1000 thank-you's! Now I just gotta figure how get it done without calling The Destruction Brigade, LOL. I'm dang tempted to put an NPT to compression adapter...

    Oil Pressure Woes - Need Advice/Help

    Oh I'm not worried about the status of their collapse function under operation. My concern is that they would collapse when I shut the engine off, just when the engine goes into a resting state. IF they do, THEN I'd be concerned pulling the filter as they could clog and fail to fill back up...

    Oil Pressure Woes - Need Advice/Help

    With three ruptured discs from a stupid move a decade ago and now this triple hernia, considering 3 of the 4 vehicles I regularly work on include an '88 Suburban, a '58 Apache, and this Tahoe... that's a $150 I think I need to come up with. If that stupid $0.99 nightmare is seriously for...

    Oil Pressure Woes - Need Advice/Help

    So I have a decent creeper, but you're gonna have elaborate on what an overhead creeper is. That's a new one for me, but a dang welcome one considering this circus! LOL The sender in 2018 was an Autozone Duralast part. In 2019, it was an AC Delco from Rock Auto. December's came from Autozone...

    Oil Pressure Woes - Need Advice/Help

    Folks, I got a heck of an issue and I'm plum out of ideas. I need some help in the worst kind of way. Sorry in advance for the length, but context and details is how you get to solutions, right? LOL Bearing that in mind, I'll give the TLDR version first: My oil pressure sender has gone out...

    Need Some Parts Buying Advice

    Call it reactive proactiviy? LOL The rear main is leaking (at least that's only seal I haven't been able to rule out), so the transmission has to come out no matter what. That would mean exhaust seals by default, but it definitely means that because I didn't replace them when I did the H3 motor...

    Need Some Parts Buying Advice

    My '07 Tahoe LT just rolled over 281.3k. Got a new long block around the 200k mark. It's a long story, but I need to do some teardown on it for a water pump and a rear main seal. While I'm in there, I really should replace all 8 coil packs, all 8 injectors, plugs, and wires (plugs and wires...

    What to Buy for a Tech 2

    Turns out my issue was low charge, BTW. So much for my memory. When I looked up the actual temperature chart I was running about 10psi light on the low side. On a whim, I said F-it and went ahead and pumped it up another 10 and it worked like a charm. I ASSuMEd I knew what the pressure...

    What to Buy for a Tech 2

    My AC will run cold, then out of nowhere will basically feel like it's just recirculating the cabin air. It's intermittent, random, and frequent enough that the cabin never gets below about 90-95F. Charge looks good, I can't catch the compressor cycling when it happens, near as I can tell all...

    What to Buy for a Tech 2

    Eh, it may be moot for the moment. But thanks for trying! I need(ed) it to read the aspirator readings to see if a faulty reading is why my air's not coming out cold intermittently. But some good old fashioned manual sleuthing (ice cubes and a heat gun on the sensor) indicate it's probably...

    What to Buy for a Tech 2

    Phoenix (Ahwatukee to be specific), but Chandler is right up the road and my tools are all in Mesa, so anywhere in the east half the Phoenix metro area is really fair game.

    What to Buy for a Tech 2

    I've search via this forum for quite a bit, and google for quite a bit more, but I'm kind of running into a wall, so I'm giving up and just asking. I'm broke, but so is my truck, so something's gotta give :) I need a tech 2 for my '07 tahoe, but I can't afford a tech 2. I'm trying to find the...

    Intermittent AC - Temp Sensor?

    Near as I can tell still cold and steady. The rear's always been a bit like an asthmatic running a marathon breathing through a straw, even after sealing the ducting, so there's not a ton of air coming out on a good day. When the front's not pulling it's load, it so hot in the back you have to...

    Intermittent AC - Temp Sensor?

    Yessir, near as I can see, that's a true statement.

    Intermittent AC - Temp Sensor?

    48 on the low side, 280-290 on the high side IIRC. High side's fuzzy because that was a couple weeks ago and I focus on the low side on this truck. The rubber flaps on either side of the radiator are long gone and I haven't found replacements, so at idle it starts recirculating the hot air and...

    Intermittent AC - Temp Sensor?

    Swathdiver, I can't afford a tech 2, LOL. What are my other options to verify? Are resistance values publically available where I could ohm it out? And when you say it's in the headliner, does that mean I have to drop that pig again? I dropped it a few years ago to fix the crummy rear ducting...

    Intermittent AC - Temp Sensor?

    Howdy all. Got a problem I hope you can help with. My '07 Tahoe LT with 260k that I've owned for 7 years has decided just working like normal is boring and has decided to throw me a curve ball. The AC (I'm in Phoenix BTW) seems to be going in and out. Like it will blow ice cold for about 2...

    Rampant Electrical Gremlins - Need Harnesses?

    Ok, so for anyone with experience with these devices, what functionality would I be losing with the WiFi stick over the full, traditional handheld device? At 1/2 the price, I gotta know... if the clunkiness of a laptop is all I gotta suffer through, sign me up :)

    Rampant Electrical Gremlins - Need Harnesses?

    No, no. He charged $160 or $170 to flash it. The rest was the ECU and labor to install it. I remember pricing the ECU, evaluating the effort, and thinking he did me right. It was frustrating that I couldn't do it, but he was fair.

    Rampant Electrical Gremlins - Need Harnesses?

    Oh I did, and they were fantastic suggestions. I guess I should give a more thorough update... The truck was due for emissions testing in August. It couldn't pass with the knock sensor. So I went elbow deep and tore the entire harness and ECU out. Inspected every square inch and found nothing...

    Gotta Have Better Motor Mounts????

    LOL, but it's not! I mean I know how to drive like a horses arse, but I don't drive like that in thus truck. Heck I haven't driven like that in a decade. Call it the castration of marriage. My '88 Suburban with 400 hp and 415 ft-lbs of torque doesn't pull motor mounts under the hardest pedal I...

    Rampant Electrical Gremlins - Need Harnesses?

    Well that ain't bad at all. I seem to remember a 4-digit price tag. $300 I can handle. Thank you again! :)

    Rampant Electrical Gremlins - Need Harnesses?

    Barf. I mean I REALLY appreciate the heads up cuz I would have been PO'ed if I bought it THEN figured that out, but still barf. I guess it's just that time to bite the bullet on a tech 2. Hopefully they've come down in price since I last looked 6 years ago, but I won't get my hopes up... Thank...

    Rampant Electrical Gremlins - Need Harnesses?

    Figured I'd post an update on this in case anyone is similarly struggling. It turned out it was, in fact, the ECU going out... at least for the knock sensor issue. $800 because I had to have a shop do it (guess you have to have a special reflashing tool?), but that problem has been no more...
