    The Rubi Q Build

    I generally tear a TC down for inspection before ordering parts as they seem to vary quite a bit on what they actually need unless you want to replace everything, but I don't like throwing parts at stuff that are not needed as that just seems wasteful. Chains and gears are kind of hit and miss...

    Trip Report October 2023 San Rafael Swell

    Thanks. Still discussing with the wife about driving down Friday night and getting a room. I'm not used to traveling without the coach and despise hotel rooms so this is a stretch for me. :rofl: If I can juggle some shop work around I would really like to make it as I am jonesing for an...

    Thoughts on Battery for '04 Wrangler LS swap

    I noticed that as well. The information I remember seeing was back around 2008/09-2014 range where they were recommending not running AGM batteries due to some nuisance codes and such.

    Thoughts on Battery for '04 Wrangler LS swap

    Yes, bad grounds can be an issue. However, on a couple of these it was not a matter of bad grounds, it was due to the low internal resistance of the AGM batteries. The ECM was having difficulty differentiating the voltage separation so it threw codes for grounds, when grounds weren't the...

    Thoughts on Battery for '04 Wrangler LS swap

    Personally I am not a fan of the AGM batteries on an LS swapped vehicle. I have seen too many erroneous DTC's and weird issues with these over the past few years. My feelings are that the internal resistance is so low that the ECM's have a hard time distinguishing the voltage separation and...

    Also, if anyone is interested I did a video showing the process and posted it to my YouTube channel yesterday. It's quite long but gives an overview of the complete process.

    General Tech What did you work on Today?

    Continuing on. Saturday morning I went out to the shop to finish up by installing the Jacobs C-Brake and adjusting it to the specified clearance of .090". With the engine already @ cylinder #6 TDC from the last of the valves being adjusted, I adjusted the compression brake on cylinders 2, 4...

    General Tech What did you work on Today?

    Continuing on. With some time left before closing up the shop for the night I thought I'd go ahead and install the rocker box and torque it in place. Whenever I use sealant on a component I prefer to let them sit overnight whenever possible, so this was perfect timing as I still had some time...

    General Tech What did you work on Today?

    Over the weekend I completed the overhead on our Cummins ISL in our 2003 Monaco Dynasty. Cleaning the rocker box. Cleaning the original sealant from the sealing surface. I used my carbide scraper to clean the flat areas then a cotter pin hook tool to clean the groove out followed by a...

    General Tech What did you work on Today?

    They were all tight by several thousandths. Near the lower end of the range but still within specification. I wouldn't have wanted to let it go much longer so I feel Cummins' recommendation of 150k miles is pretty spot-on.

    General Tech What did you work on Today?

    I was able to get some time on the coach last night and got the valves adjusted. I prefer to use my stepped feeler gauges as a go/no-go gauge. I adjust them down to where there is slight drag but the stepped portion won't slide under. Then I torque the jam nut to specification, mark the...

    General Tech What did you work on Today?

    Made a little more progress on the Cummins ISL last night. I started by removing the wiring for the Jacobs C-Brake and then removing the six bolts for each section of compression brake. Before removing I backed off the center stud space take up shim so it is ready to be reinstalled and...

    General Tech What did you work on Today?

    I started running the overhead on the Cummins ISL in our coach on Saturday. Cummins recommends running an overhead @ 150k miles and with our coach now over 140k miles, I figured it was close enough and I would just run the overhead now along with oil and filter and chassis grease so it's ready...

    General Tech What did you work on Today?

    Yeah, once or twice. :rofl: Here is my 1940 Chev coupe that I built back mid-90's. Was featured in Street Rodder Magazine in 1997. Won 1st place in class in Boise Roadster Show same year and was one of five cars in the running for Utah's Finest a year later. Here is another street...
