ZMotorSports 2011 JKUR Build Thread

Continuing on with the repair.

The next part I think was my own doing. A couple of the plug wires were hard to reach upon disassembly so I thought I'd test them before reinstalling and I'm glad I did. One wire tested open while all others were good at around 770-790 ohms. This one tested open and upon grabbing it and pulling I discovered why. Shit, wasn't planning on new wires and I couldn't easily locate a single so I had to buy a set.



I've seen people slather dielectric grease on the ends of the boots before so I thought I'd share my thoughts. Dielectric grease on the end of the boot really does nothing to aid sealing. It is really used to coat the porcelain of the plug and aid in sealing out moisture from the boot as well as aid in removal next time.



You can either apply it to the porcelain of the plug before installation or the boot. I like to use a rubber installation tool for installing the plugs so that negates the ability to use the dielectric grease on the plug or it will just spin on the install tool. Therefore, I take a little on my pocket screwdriver, not too much as it really doesn't need to be slathered all over. In fact, some people just spray a light coating of silicone spray in the boot which would also work. I've just been using dielectric grease for decades and am kind of stuck in my ways. :bounce:



Put it slightly up inside the boot. Next when installing the boot onto the plug, give it a bit of a twist to spread it uniformly around the plug. Then snap it onto the plug and orientate the wire to the natural lay of the wire in relation to the coil.



Plug wires installed.



After the test fire, everything was double checked and the engine cover reinstalled.



The wife and I went for a test drive that night for dinner and then on Sunday, New Year's Eve morning I went back out to the shop with coffee in hand to give the shop a good cleaning in which to bring in the new year.










Thanks for looking.

Also, for anyone interested, here is the video that I posted to my YouTube channel showing the repair.

Always enjoy reading about your projects. Great write up.

Thank you.

Nice write up as usual. I had a spring fail in my 2021 6.2L. Then the last 6.0L I built had a broken spring when I took it apart. That was strange because it ran fine. I believe there is a TSB about spring failure in truck ls/lt engines. That 6.0 and the 6.2 I’m building now got upgraded springs. As a rule I won’t use stock springs.
Glad it wasn’t worse.

I haven't seen quite the issue in the truck/SUV engines as I had in the C5 Corvettes. This was actually very common in the early 2000's Vettes with the LS2 and many were changing over to the LS6 springs at that time.

I have read a few online in the truck/SUV forums but they seemed few and far between.

Funny though, out of all of the Hi-Po engines I've built over the past 35 or so years, this bone stock engine is the only one I have had a spring failure in.

But yes, glad it wasn't worse as this could have gone several different ways very easily and they would have been catastrophic.

Hey everyone.

Been MIA for a bit as I've been busier than hell and trying to get caught up after finishing the attached garage earlier this year. Now that my attached garage is complete I can get back to work in the shop but have a lengthy list of things to do.

I was contacted a few months ago from Dustin, who has a YouTube channel called Tool Box Tours. He asked if he could interview me and show my toolbox and shop on his channel. At the time I was neck deep in the house garage job and everything from the house garage was being stored in the shop so I declined at the time.

He reached back out a few weeks ago and I had just completed the house garage so I figured what the hell.

Here is the video that he did of my shop and tools that posted over the holiday weekend.

It's fun to watch you light up and talk about your tools... I'm less than 10 min in and this is already a great video.

Thank you. I've been accused before of being passionate.

The money that you have invested in your shop tools is incredibly, but what impresses me the most are your skills and knowledge. Wow, just wow!

Thank you.

Over a 35+ year career as a mechanic, I just took on various jobs, basically whatever came through the door for many years as I was trying to establish my name and place in the market. While I was watching the video, it kind of hit me that I was fortunate to have worked on such a wide range of things and not just one specific make or model. Granted, I needed to have vastly more tools to work on a wider range of things, but I think the experience and knowledge gained is much more beneficial than specializing. At least that's my take on it.

Yea, your recall on the reasons you have specific tools is impressive! So much knowledge and experience. So cool.

Thank you. I'm sure there were a few I forgot though, and many I didn't even show due to time constraints.
