Builds ATC Fleet Ops: RhinoRide60, RMR60, PlowPig55

Thanks!

So I didn't have much planned for doing to my 60 after Moab, but the addiction raised it's ugly head and I wanted to add some extra lights on the front of the ARB and I liked the Hella 4000's EX has on his 60 so I picked some up with the wiring kit. If you haven't seen how overbuilt these lights are they are worth the cost. They're cast zink so they won't rust and are very rigid and won't flex like plastic lights.

Another nice weekend and the 60 bug bits again...I've read alot of debate about the ARB bumpers jack points on the lower part of the bumper and how they are for jacking and not for recovery, so I wanted a more solid recovery point and picked up some bolt-on recovery points from OKoffroad.com. The kit comes with the recovery points, grade 8 bolts/washers and shackles. All nicely powder coated in black. They sell the backing plates, but I went ahead and made up some 1/4 steel backing plates. The toughest thing to do was drill the holes in my ARB, but after kissing a rock in CruzMoab and giving it some "character", it didn't hurt to much.

What happened...octane knock??

So, all of a sudden I've noticed a "ping" or "octane knock" when under load in third/fourth gear. I have no clue what would have caused it. It's performed great all summer and while in Moab.....I don't drive the 60 everyday and it primary sits in my garage. I do drive it on the weekends and top the gas tank up when needed. It starts up easily, idles smoothly and rev's/pulls strongly.

It seems most noticeable when I shift to third and going up hill (load) where it makes the most noticeable ping/knock. I sounds more like a low octane valve train type of knock, but I haven't changed gas or gas stations.

After doing MUD research I did a carb adjustment, cleaned the distributor and rechecked the timing (note: the timing was right on 7 degrees) and added some techron....nothing. I advance the timing to just past the mark (maybe 10/12 degrees) and nothing....It's still fully smogged and I checked the HAV per the FSM and it seems to be operating properly...

Any ideas?

Thanks!

One possibility is the change to winter formula at your gas station. I think they also up the ethanol percentage in the winter formula. I don't know that either your gas station has changed to winter formula or that even if they did that this is your problem, but you might check with the gas station manager to see if they switched to winter formula right about the time your problem started and if that includes a higher percentage of ethanol.

Use 93 octane and dont advace the timing but take a few degrees away. Adding timing will just make the audiable knock worse.

Good point.

I purchase my gas from QuickTrip (QT) here in Kansas City, so I feel confident it's decent fuel, but I'll check with them.

Thanks!

Where is the air tank?

Have just read the thread. You seemed to have covered everything in great detail. Pictures are pretty informative. However, I was looking for the airtank used for the locker activation. There is a company called Cheesy Enginnering here in Australia that uses the side rock sliders as airtanks. This seems to be what you have done.

The shot of the campfire and the wagon nearby kitted up, looks like it could be somewhere south of Alice Springs in central Australia.

Whats next?

I could only wish to be wheeling in Australia!

I don't have any type of reserve air tank. I run the frt/rear lockers off the ARB HD Compressor. I also have the inflation kit for it, but thanks for the suggestion. I may look into a reserve tank some day.

As for next trip, I'd love to get out west (Colorado) one more time this year, but I don't think my schedule will let me.

Take care and thanks for the suggestions!

Another cool Moab pic...

Fantastic time! Thanks Ex!

Awesome!
should have had Kurt pull him out! He's set up for that type of thing
Great photos, wish i could have been there to meet ya next one though

Yep..from what I understand, the white Taco was Kurt's old truck so he gave the driver a lot of grief about getting it stuck! Lot's of fun!

Great looking Cruiser
At the last photo, what's the name of that trail the you can see on the bottom?
I have being on Moab many times but I don't know that particular trail.
Thanks.

I'm not sure what the trail is at the bottom of the canyon. We followed a small trail off of "Behind Rocks Road" and found this view. The pass in distance is "Hurrah Pass" leading to "Chicken Corners" via "Kane Springs Canyon Road"....

Here's a google map link of the location.

Goodluck!!

ya, it was! sounds like Kurt. suprised he didn't make him self recover just for a lesson. He should have sold him an exhaust jack on the spot.

I swear.....you and Brian are connected at the @#$%...He looked at tonight and we reset the timing to 7 degrees and I'll try some new gas once I run the tank down. May try some seafoam to give the carb an enema.

Thanks!

Hope all is well in your world. BTW, I may find myself in DC in December...are you guys anywhere close?

Yeah screw you too. lol With the way gas is being made I find it best to run 93 in everything i own except the diesel and Silverados SS, it gets 110. I have learned with tuning on it(ss) that depending on the fuel I can adjust the timing 10 degrees in either direction. I run mid 30 degrees on a street tune and low 40s at the dragstrip.

Just let me know when and where. I am always around. My mother and father inlaw live 10 min from down town dc. Oh I got my 40 running

 

[AdventureToolCompany]

Thanks Matt.

I hope to tinker this weekend and will update.

Thanks about DC. I'll LYK if it happens.....Congrats on the 40!!

Octane Update

Tinkered this weekend.

I finally ran the old gas out and added some 93 octane. That seemed to help, but I either still had something in the fuel or a different problem, so I added some Seafoam to the gas and after a little bit of running around it sounded a bit better....So, this weekend I pulled the air cleaner and ran a full bottle of Seafoam through the carb....what a smoken mess...I had my neighbors coming over worried that I had blown-up my engine! It now seems to idle nicely and no more "octane knock" under load.

One of the problems suggested was carbon. If this was the problem, I assume the Seafoam removed enough to smooth things out. My question is how the carbon got there in the first place?? When I adjusted my carb I did notice that the Air/Fuel adjustment screw was almost completely screwed out, so a screwed it back in and back it out per the FSM....would this have caused a carbon build-up?

Thanks for all your suggestions and help!

 

[mwalls54]

it could have been fuel or dirty carb. once you put new fuel in it still takes a little bit to get it up to the carb. so maybe when you did the seafoam it cleaned it out. and it could have cleaned the carbon build up in the motor. the carbon comes from the fuel combustion. It will stick to the combustion chamber, valves and the top of the piston.

When I adjusted my carb I did notice that the Air/Fuel adjustment screw was almost completely screwed out, so a screwed it back in and back it out per the FSM....would this have caused a carbon build-up?

so your saying you had a screw loose. lol but glad its running good again
