Took off the grill and cleaned the heck out of the condenser and radiator. They were filthy!
It's about to be 120 degrees where I live so I wanted to be ready.
The ac seems to cool off way faster and gages say truck is running 3 degrees cooler after the cleaning.
Noticed that the oil in my catch can was very, very dark and that oil has only been in the truck for 2k miles since I discovered the oil burn problem. Pretty sure when the oil got so low before I noticed it left some sludge behind.
I did a liqui moli flush and refilled with super tech...
Just checked the catch can after the first 550 miles with it. Had about 2 tablespoons of oil in it. Have about 800 miles since topping up the oil and it doesn't seem to have dropped any. I don't have a frame of reference but 2 tablespoons in the catch can doesn't seem too bad to me after 550 miles.
Update on this. I ran the redline fuel system cleaner and have been running the truck hard! I am just about through a full tank with the redline.
I emailed redline and they said to run 1.5 ounces of cleaner per 10 gallons of gas after the first tank with a full bottle of cleaner is finished...
I only have one vehicle and I use Mobil 1 extended performance high mileage synthetic. Pretty sure it's not the oil (as in totally sure lol). Might try another brand when I switch to 5w30 to see if that helps at all. I've always used Mobil 1 in all of the vehicles I've had and have never had a...
I've been running Mobil 1 extended performance high mileage full synthetic, I might try switching to redline as I've had good luck with their gear oils.
I had a 5.9 Cummins and loved it. Unfortunately I wasn't in a financial position to buy another when that truck got wrecked as I was in college and just starting out. When this truck gives up the ghost I'm definitely getting another Cummins, the Cummins is better than the hemi in every way for...
I realize one guy with a borescope does not make a scientific study, but the results are interesting nonetheless! Here's a before and after video of redline fuel system cleaner taken with a borescope down the plug holes. Cylinder 3 impressed me!

I clicked the link, it looks like a 30w oil
I clicked the link, it looks like that product is a 30 weight oil with additional detergents etc. If you use it, post back with the results and let us know how it did.
Just came in from checking the intake manifold bolts. They were all perfectly tight, no looseness whatsoever. Also, the redline is supposed to be delivered today so I'll run that once it shows up.
I read through the first 6 pages of that thread. My truck has always bounced around a bit on the idle and definitely not smooth. I saw some guys in that thread had the same issue, bolts were very loose and tightening them corrected the issue. It's almost dark here now and I'm going to the...
Thanks for explaining. I'm fairly mechanically competent and do most of my own maintenance and repairs. I just didn't understand the joke! Yes, when I was just starting to work on cars I definitely found myself in the situation you describe. Luckily if you do that enough times you learn to...
Yes Sherman, that's how I'm approaching it. Will it do something? Maybe. But not doing anything will change nothing, so it's worth a try. That's how I look at it
Is there a certain brand of catch can everyone likes for the 5.7? Or is it a "buy whatever" type of part where it doesn't make much difference who the manufacturer is?
Yeah once I get the catch can installed I will take off the TB and clean it up. I've taken it off to clean before but it's been a few years. I'll pick up a new gasket for it while I have it off.
I think for now I'm just going to run the redline, maybe run some seafoam in the oil before the next change, and switch to 5w30. Realistically, I think that's about all that can be done. I'll probably avoid that "restore" cleaner that was posted, I'm not sure I would trust replacing that much...
Clearly I didn't understand his post. Also, don't understand how a loose TB would cause this so that's probably the joke lol. Saw the sarcasm tag, wasn't sure what he was trying to say!
