    Broken Rocker arm and bent pushrod

    Was this a fluke, or do I have something messed up? Haven't had this issue before, but just got the motor back together. Can having not enough lifter preload cause this by chance, because I did use shorter pushrods than the previous time to get my preload in check. I'm wondering if I got it...

    Temp Sensor -38 on scanmaster correct on PL

    I have an issue where my temp sensor is reading -38 on my scanmaster, but reads correctly on the PowerLogger. Car starts hard when cold, so assuming this is causing the issue. Is this just a bad TS or do I have a wiring issue. Just reinstalled the motor, so wires were being moved around...

    Milky oil...trying to find the cause

    End of last season I notice the coolant was low and then check the oil to find it was very milky. Car was running fine, not missing or smelling like antifreeze. So, I decided to pull it and go through and make sure that everything was OK. Specs • 291 4.1 block • Champion Irons • Fel Pro 1000...

    E85 analyzer through Powerlogger

    Is there any way or system that would allow the use of a flex fuel sensor to monitor ethanol percentage through the Powerlogger? I'm not looking for flex fuel capability, just a way to monitor the ethanol percentage.

    Need some help and opinions on combo

    My best 1/4 mile slips are attached. I know there is more in it, but I'm stuck with how to get it out. I think the turbo has more in it, but I'm running into a bottleneck somewhere along the line. Here's my thoughts on my bottlenecks right now. Stock Dutt Neck intercooler is probably a huge...

    4.1 timing tab question

    I used a stock 4.1 14 bolt(pan) timing cover on my 4.1 build, but it seems like the cast in timing marks are off from the 3.8 timing tabs. Does this sound right?

    Fighting some knock issues

    Running boost at 22-23lbs, and fighting some KR issues that I don't think should be there. Tested my fuel and it's coming out at E80. Is my stock IC creating a bottle neck that is causing an increase in charge air temp? I'll attach a log of a run with the KR on it. It was an 11.48 @ 116...

    Finally back running. Time slip and log attached. Suggestions please.

    Saw some KR close to the shift points, but it also looks to be maybe a little earlier than that. Let me know your thoughts. Running a 6.1 WB CHIP WITH 10.8 AFR IN 1-2 AND 10.5 AFR IN 3-4 The video started a little late, but here it is anyways.

    Leaking Torque Converter

    I bought a new TC a couple years back from a board vendor, and have been trying to chase down a trans leak ever since. Long story short, engine rebuild, balancing issues with it, trans issues, and now I'm finally back driving it. Anyways, I've now narrowed the trans leak to something in the...

    Replacement A/C lines

    Any options? I need the lines that come from the back of the compressor. I've checked gbodyparts, highway stars, gmpartsdirect, and a link to an email from Norbs in a thread from 2011. No luck so far. Thanks, Cory

    2004r 2-3 flare

    Does anyone have an idea of why I have a 2-3 flare when manually shifting, but a super hard quick shift when left in drive? Extreme Automatics Stage 2 less than 1000 miles, but 3 years old. Fluid looks and smells good, no junk in the pan.
