The RedBurb

Every Part Is Replaceable
Just now able to get connected to the site. Sharing part of my morning drive into the office.

I love the sound of the 6.2 l.
Not like the other clackety clack of the diesel engines.
And I think the gearing is just right for whatever tire size you have. Acceleration and cruising feels good

Its a great sound. Especially with the M998 intake. Really opens it up. Tires are about 33s and yes it rides pretty good. Even better with 37s. But those will have to wait a while. I’m very happy with how it’s doing.

I think the 35" will be good too, not sure how the 37" will fare with the gears you have.
You need to see what your rpms are at cruise speed.
The diesel likes to be at lower rpm for better mileage.

Actually the 37s SHOULD put it at lower rpms. Current gear ratio is 4.10, and it had 37s before and seemed to like them. Rpms actually went up a bit when I went to 33s. According to the rpm calculator, the Rpms should drop by about 300 or so with 37s.

I know the 37s will drop the rpms but I don't know where you're at now.
It feels like it's good and could take a little bit bigger.
If you have 4.10 i will do some calculations and see what I come up with.
Mine is 4.10 too and I am waiting to get it running to see how it feels with the 33" and go from there.
I also have a turbo

This is your ATS burb, yes?

I'm running 33" tires on 3.73 gears with 0.73 O/D. Very similar engine setup. If anything I wish for a lower cruising range (bigger tires). I had a 6.5 with 4.10 gears and 33" tires. It needed another O/D gear, IMO. On the other side of the spectrum sat my stepside. It was a bit anemic, but turning 1625RPM @ 65MPH was so nice...

I am thinking the 4.10 will be good with 35" and still have the power to tow a small trailer or boat.
I had a burb with the banks turbo, 3.73 and 33" and it was pulling the hills at 70mph easily.
If I remember correctly 1800-1850 rpms is where the engine is happier for better mileage

This is what I have been using to calculate where my engine speed would be with different tire sizes and 4.10s. Focusing on the AOD figures, this is what happens to the engine speed with a vehicle speed of 70mph.

33s: 2046
35s: 1929
37s: 1824

So it appears that my #5 injector is leaking, or the line is leaking at the injector. Made sure it’s good and tight. Hmmmmm ....

Hard line or one of the rubber overflow lines?

The hard line should be tight, but not super tight. Check the split in the injector body. It is easy enough to start unscrewing the two halves when removing the hard line.

Or maybe the hard line is loose.

Pretty sure it’s the hardline. Almost looks like fuel is coming out of the 3/4” fitting where the hard line goes through it into the injector, but the fitting is tight.

Everything around it is wet though.

I’ll check the split in the body tomorrow and post up what I find.
 
Looks like the line. Pull it off, check for anything obstructing the seat, make sure it's aligned properly, and tighten it back up.

Well last night I had disconnected the line at the injector to make sure it was seated properly and retightened, but still leaking. If I can find time today, I’ll check to see if the injector itself has come loose. If that’s not it, then I’ll look at taking the whole line off to inspect. #5 is at the bottom of the injection pump so I might have to disconnect others to reach it, unless there is a special type of wrench I can get to help reach it.

That's too bad you were just there and I don't know of any tool that makes it easier.
You can make one by heating and bending the wrench.
 
So I’ve got good news and bad news. Good news is that I don’t think my #5 injector is actually leaking. Bad news is I think it’s power steering fluid leaking from the seam between the hydroboost and master cylinder. Will try to find some time soon to separate and see where and why.

Hard to see in this photo but this is where I think it’s coming from:

Actually the injector may have been an additional issue, but I think I got it tightened up bc it’s dry now. Probably have an issue with a seal in brake booster, will look into that at some point, and then am also running another theory will see how it turns out.
