Well since I have the V8 pretty close to dialed in, it was time to get ready for some longer excursions up the mountain passes. With that in mind, I picked up some cargo nets to help keep all the camping gear in the back.

The weather can also be an issue so I picked up some soft windows and frames off craigslist for 30 bucks. These things are brand new and I don't think they have ever been installed. They fit right underneath the tonneau and above my trunk lockbox so if they weather turns, I can throw them on real quick. I also can fit my half doors in the baja rack that I built once I hit the trail.

We had a camping trip with my parents planned in Leadville for this weekend so my Dad and I drove an hour south to Buena Vista to knock a trail off the bucket list, Chinaman Gulch! Finally time to fill this thread with some much needed wheeling photos!

Start of the trail:

Came up on the first obstacle known as the Rock Garden:

Next obstacle up was Whale's Tail. I tried the harder line several times and with no rear locker, I just couldn't make it up. Came to find out after we got up above, that there was a winch hook up spot. Had I known that, I could have hooked up and gotten up but thats ok. I also almost fell off the side and had my first flop but I got lucky and fell into the rock gap.

So I moved over to the middle line and eventually made it up. Don't have a video of that for some reason but this was another spot where the rear locker would have some in handy.

The last obstacle we came up on was the waterfall. I made it up about half way and the no rear locker factor bit me again. And I think I might have needed 37's to get up. Ended up winching out on the second part of the waterfall.

The next day we ran about half of Mosquito Pass where this photo was taken.

Thanks! It's one of my favorite trails that I have run! Working on her and wheeling with my Dad, now that he has a jeep, is by far the best thing about my jeep!

So all winter long I was dealing with hard starts in the cold. This is a common issue on the 5.7L vortec. Well recently I've been dealing with either a leaking injector or fuel pressure regulator and when I was camping, it was very cold in the morning and the jeep was hard to start. I decided to bite the bullet and upgrade the CSFI poppet injectors to MPFI spider injection.

Here is a picture of the current CSFI (Central Sequential Fuel Injection) injectors with poppet valves:

Name:  SCFI Injectors.jpg
Views: 95
Size:  13.5 KB

On this setup the injectors are up at the top and it pushes the fuel through poppet valves at the tip. These poppet valves are controlled by a mechanical spring and are are very sensitive to fluctuations in fuel pressure. Not enough pressure and the valve won't open enough, while too high of a pressure will unintentionally keep the valve open too long, leaking fuel into the cylinder. The tip of the poppet valve conducts a large amount of heat allowing for carbon to build up on the tip of the valve causing them to plug up.

Here is the MPFI (Multi-Port Fuel Injection) upgrade that I just ordered.

mpfi-injectors.jpg

Name:  spider_injector.jpg
Views: 96
Size:  88.9 KB

The MPFI Spider incorperates a small electronic fuel injector at the end of the fuel line. notice the long pintle cap tube attached to the injector. This long tube allows the end of the injector to be recessed away from heat and vapors that cause carbon build up on the end of the injector.

The major difference between the two systems is that the aftermarket system removes the faulty poppet valves and replaces them with electronic injectors located at the end of each fuel tube. These new injectors have a much larger opening making it very difficult to clog an injector. In addition, the injector is now opened electronically instead of mechanically. This maximizes the performance of the engine by precisely controlling when then fuel injection begins, as well as the duration of the fuel spray. This will translate into a quick, crisp response during start up and acceleration.

This is a direct swap and a little pricey but I hope this solves my hard starts, leaking injector or FPR and improves performance. Ill probably get around to installing it next week sometime.

My fuel pump is also on its way out again and my fuel gauge has not worked since the motor swap. I have a bunch of metal shards in the tank from who knows what so Im going to drop the tank, clean it out, install a new OE Bosch fuel pump that I also ordered and get my gauge working right.

Fingers crossed that this fixes my fuel issues and hard starts.

This past weekend, I knocked out the injector upgrade.

Old vs new comparison:

890.jpg

The intake was filthy with built up carbon deposits so we cleaned that out:

889.jpg

And installed the new MPFI spider injector upgrade:

891.jpg

Then I went ahead and swapped out the Walbro fuel pump and went back to a stock OEM Bosch fuel pump. I did look into the tank and it was not near as dirty as I thought It was. I think I was just burning through fuel pumps because of the hard start issue.

Also fixed my sending unit. The arms that provide the signal were not touching the contacts so we bent those back into position and now the fuel gauge reads correctly and works...only when the key is in the on position but the engine is not running. The second the engine fires, the gauge loses its reading which tells me I have a short in the wire or it is grounding out somewhere. This will be an easy fix as it is only one wire and it will be easy to trace, I just didn't have time to get to it.

The difference between the CSFI and MPFI spiders is extremely noticeable. It improved the performance a lot more than I thought it would. Throttle response and acceleration is much improved. Prior to installation, I would have to prime my fuel pump 3 or 4 times and it would take about 7-10 seconds of the engine turning over to fire. Now she fires up the moment I turn the key and I couldn't be more happy. I have been dealing with these hard starts for more than a year and it is now nice to have the piece of mind that I am not going to get stranded somewhere nor do I have to wait 5-15 minutes to get it to start. I am am not sure how it will affect fuel mileage as I will need to go through an entire tank to tell but I'm sure there will be some improvement there as well.

"

I am very pleased with this upgrade to say the least.

Last wheeling trip out this summer, I asked the girlfriend to adjust the passenger mirror. She broke it, my fault as I didn't explain to her how it adjusts. So since all the aftermarket stock YJ mirrors are all cheaply made trash, I put on some 03-06 TJ mirrors. They are solid as the adjustment is inside the frame so they don't move on the highway like the YJ mirrors.

Took advantage of cyber Monday, saved some coin, and ordered up some Battleborn Beadlocks for the upcoming axle swap!

Wow. Didnít realize itís been 4 months since I even posted in here. Guess there hasnít been a lot going on with the Jeep.

But...after 16 years as my daily driver, the ole girl is now being retired and is now officially reclassified as a toy.

0e2e245c-9b3a-4c2b-9fff-d03129faaa2a.jpg

d7407952-ab2b-47dd-82e9-38c4d8d44a0c.jpg

And now an update for the Jeep...Iíve decided to put off the axle swap till next spring.

Main reason being, is that my Dad and I have always had plans to run Black Bear Pass down into Telluride. Itís a pretty narrow trail so Iíd like to knock that off the bucket list this summer before going to full widths.

Plus it gives me more time to spread out the costs and slowly accumulate all of the parts I need for the swap.

But as of right now, Moab is in the plans, May 15-22, to rendezvous with @AZdEvilYJ , @Randonexplosion and gang when they will be there the 16-19th.

There are a couple things Iíd like to get done before heading out there:
- Get the OBA converted for the 5.7 and rerun my air lines. Multiple reasons for this...air up after trails quickly, blow all the Moab dust off me after trails - blow up air mattresses, paddle boards, bike tires etc.

I need to make an adapter bracket to mount the York to the factory AC bracket and swap out the v-belt clutch for a serpentine clutch.

- Try and get my clocking ring to tcase sealed up. That thing has always leaked since the motor swap. Itíd be nice to not have ATF everywhere.

- Fab or pay someone to Fab up a fan shroud for me. On most trails here in Colorado, she does fine and doesnít overheat but last summer we tried to do a couple mountain passes and I had to shut her off several times so it didnít overheat. I can imagine I will run into that issue out in Moab with the crawling that we will do and the temperature outside.

When I went to Moab right after the swap, I didnít have issues with overheating but I later found out that was because my thermostat wasnít functioning. I found that out when winter came around and I had no heat so itís since been replaced. So a shroud is definitely a need before the trip.

I only have 5 weekends before the trip so we will see if it all gets done or not. Timeís a ticking so I better get going on it next weekend.
