DIAG VIDEO on second channel: Major Work Needed! 2008 Sierra 6.6 DURAMAX https://youtu.be/KBombJTVEO4
Repair Pt1: Exhaust HOLE! Weld the Manifold! Electrical System Amp test. Silverado Sierra 6.6 DURAMAX Lbz Lmm
This truck came in with a hold drilled in the passenger side exhaust manifold. It looks like someone had drilled the hole and attempted to install a thermocouple to monitor exhaust gas temperature or EGT’s. It appears that the probe is no longer installed leaving a large hole in the iron manifold. The proper repair would be to replace the manifold. Due the rust and corrosion on the bolts, it is likely that the bolts will break off and will have to be extracted from the cylinder head. Additionally, replacement manifolds cost hundreds of dollars. Filling the hold with a bolt presents its own problem due the the thin material at the holes location. Welding the hole closed was the most cost effective approach to making the repair.
A quick check of the starting and charging system revealed an entirely different set of problems. There is also a massive coolant leak and power steering fluid leak. We’re trying to patch this thing together making the vehicle reliable safe and functional again.

Thanks to Jesse for making the intro and graphic for us to enjoy!!!
Great video Ray
Electricity is lazy and always takes the shortest path. That being said, if you clamped onto the frame and had a bad engine ground, yes you could fry modules but I like to believe, if you own a welder, you probably know to put your clamp on piece being welded.
Back in the '50s and '60s welding cast iron with torches didn't usually work well which is where the myth comes from. TIG and MIG are very different animals.
To many armchair mechanics.😢
Put the big channel locks on that hose, start twistin' it one way and then the other till it breaks it's bond. You're going to replace the assembly anyway..right?😊 great work sir.😊
1:02:16 you're definitely damned if you do, damned if you don't. That's how the YouTubes goes, can't please everyone all the time.
Thank God i don't turn wrenches anymore. The rad hoses aren't even simple anymore. Who was the Generic Motor's engineer that thought that mess up?
Call me crazy, but it looks like if you tie a chain to that hose, connect it to the bench and backup the truck out of the shop as fast as you can, problem solved lololoolololo The idiot that designed that needs a trip behing the wood shed lololololo Good Luck, Great work as always.
Sadly the cost to replace that hose was more than the cost to replace the O-ring
I'll have to go back and watch that video, but you can definitely weld cast iron all you have to do is preheat it first and grind a groove in where it's cracked to give the filler room. Just because they can't weld it doesn't mean it can't be welded.
I see now why it takes so long to replace the lower hose.
That's a really bad design for a radiator hose.
To stop the welder gripes ask them how a waste sparks ignition works.
To avoid getting soaked by coolant with disconnecting, just slice the hose at the low point. It's being changed anyway, so no harm. I've replaced a couple dozen of these hoses.
Nothing wrong with welding the hole up the way you did. A-holes will pick apart anything you do in public.
Personally before I seen your vid I would have found a short bolt that fitted in inside the hole and welded that to the manifold.
Clearly you have plenty of experience and always double check your own work so good on you for all the great work and content you put out. Ignore the A-holes
People don't understand old school mechanics. Welding that hole was a great way to safely fix the problem and save the customer some money. People that don't care about customers would want to replace the manifold and charge for drilling out the studs if they broke. You care about your customers and getting the problem fixed. Keep doing you Ray, 🖕🻠the trolls.
Don’t worry about the armchair haters who can’t weld. It all stems down to someone’s idiot grandpappy who don’t know his head from a hole in the ground. Saying you can’t do this or that when welding
Reeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee
Ray don't bother with the haters stupidly meticulous folks that leave negative disrespectful and/or disparaging comments. Love your content and the knowledge you're sharing. Folks need to understand that your content isn't a step by step bc you're wanting to keep the vids as short as you can. Me personally, I'd watch if they were 3 hours long. Anyway keep it up bro and to H-E-double hockey sticks to the haters.
Can girls be macanics
How dare you, don't you know that posting a comment on YouTube automatically makes you an expert on everything. If the experts say you did it wrong, then you must have done it wrong 🤣🤣
The only argument that holds up is the one about spatter going in the hole before it's closed up.
As a welder and a duramax owner i approve of welding manafolds and other things as needed.
Regarding the derisive comments about welding the manifold, Green's Law of Debate states "Anything is possible if you don't know what you're talking about." I ain't sayin', I'm just sayin'.
Man, those Reee people need to get a life. I realize you don't want to subscriber's, but there's a time where you need to remove these people who think they know everything better that a career mechanic. Reading these shade tree mechanics comments is getting old. Can't you just watch Ray's content for its intent, education and yes entertainment.
