Hi there, help me understand here, why small diesel sedans or some pickup trucks don't have exhaust brakes. at least when it comes to pick up trucks they weigh up to 3 tonnes, imagine them towing something, that number will be 4.5 tonnes which is like a small city truck. i think it should be necessary but they dont have engine brakes at all. Why?
It's junk. Do not putanything inyour oil. It messes up the balance of the additives your oil company uts in it. The oil and bearing people work together to do it rght.
I just started watching, but i remember when you pulled the valve covers. You had little to no oil to the rocker area then, and it won’t be better now. You have a lack of oil pressure to the rockers. you need to look at the oil delivery system. Yes, you might need lifters, but that is a symptom, not a cause.
Brother pump generates 1200 psi pressure to injector ok correct your knowledge about fuel pump and injectors and about pump pressures it depends on the brand of fuel pump
From my understanding the ecotec engines or any fuel saving engine cuts fuel off to those certain cylinders saving fuel but what they don’t tell you is the fuel acts as. Lubricant to the cam lobes.. so I take it both of the back cylinders were the ones that get cut off.software hacks you can do to keep the ecotech mode off there by keeping engine lubricated .. now the world knows. Moment.. ecotech great on gas but very short life..
So I have the 3126. In a 1998 Pete 330 retrofit 14 whl dumptruck. Running Class 8 @ 61,000lbs GVW. Yep. Thanks to positive input from Josh and a very competent and FEARLESS local mechanic we run it hard every day in the desert metropolitan market. Bought 1.5 years ago from a reputable builder (was a trade in) but the cups failed on the fourth day in service . Rather than the Cat kit with new cups and special tool, I was offered the option of going with the Cat reman head which seemed a valid upgrade. Now running HARD every day with zero issues. ------- Note to all: The HEUI system DEMANDS clean engine oil for top efficiency and engine (HEUI pump) life. It MUST be changed every 250 hours REGARDLESS of the miles (or 5,000mi). That's once a month for us. Cat filter/Rotella. 709,000mi/33,000 hrs currently and the shop says the flywheel has been machined thus far to suggest replacement at next clutch. This "may" be an indicator of (guessing) the history of the pistons/bore condition. If still original, I'll be the first long block guy on this one lol! Long story short folks, Cat rules. Cheers!
Looking for a coolant drain just seems so quaint to me. Most stuff here in Europe hasn’t had a dedicated coolant drain for decades, you just take the lower hose off the rad. God how I wish we still had drains. Even my old 80s BMW didn’t have one, or my 1970s Reliant Scimitar (which had a Ford 3 litre V6). Perhaps even more quaint is seeing pushrods in such a modern engine. I can’t even remember the last pushrod engine in production over here. I actually really liked pushrods, especially in a high cam engine so the rods were short, it made head gasket changes so much easier.
Or better yet, you can locate , Rebuild and install A 3406B Fully Mechanical Cat. And save yourself the Headaches of Computer Controlled Engines, DEF and ELD B.S.
My dad and his brother never changed there oil for the life of the car. Just topped it up. Never had a problem in the 40 plus years of doing this. All his vehicles hit high kms before selling them. So do you even need anything?
Not sure why but silverado's you got a 80% chance its just the lifter. Every van I've done lifter has turned in the tray and mushroomed at the bottom and ate the camshaft. Only had very few turn on the trucks
Know your pain up in nwt working on ford f350 have to remove cab just to change HP fuel pump. All bolts for cab broke pain in the butt . HD tech working on ford junk .nice vid.
Yes, i start & run for 10 minutes while i do my start of day walk around. I also run it 5 minutes when i end my day before shut down to make sure the turbo gets a chance to cool down.
The fuel station where I fuel up called everyone that put fuel a couple days ago and said their driver accidentally put gas in the diesel holding tank I don’t know the percentage so I’m guessing I need to obviously need to drain the fuel tanks change filters and blow out the fuel tank lines and what else
Regarding the markings on the Multi-V-belts: 6PK1972 means 6 ribs (6PK), 1972 is the length of the belt in mm. Thanks for taking us with you on your repair journey. :)
Good find on this, and good job trusting your gut on this one. I'm surprised with that damage that you didn't feel more of an imbalance in the engine operation, maybe you did and didn't discuss it. All of that extra junk they put on modern vehicles is annoying to me too, but it comes down to various regulations and standards for NVH (Noise/Vibration/Harshness), and especially noise. There are regulations around how loud a vehicle can be from the outside, basically reducing how much it annoys people walking down the street. You can remove those extras without causing harm to the engine (although the balance shafts you might want to keep). That noise cover over the engine would be one you could consider not reinstalling, the question is how much you want to hear that V6 yourself while driving. I've never known a GM V6 to produce inspired sounds. Overall, I agree, GM has a tendency to make engines that are pretty good and pretty simple to work on. And yes, the torques are way, way lower than you're used to on Cats. 🙂
I always replace DexCool with a thorough flush and then Cat DEAC. Never have it gunk up that way like DexCool can/will, and DEAC is compatible with rubber hoses and aluminum components. Vans are great until you have to work on them. Then they become the largest POS ever designed
I did not read all the comments. I think someone suggested that you get an Alldata subscription. Thought I would give you this hint. Most public libraries have access to some type of an online repair manual service. You can go there and look up what you want and print out the repair process pages for a small fee.
YUP, that went about as I expected it.😂 Well, at least it made for one very entertaining episode. Looking forward to the next one. Good luck and keep your cool. 👌😎👍
gm says fuel lines are not reusable I did lifter on my friend SUV and he didn't order them and told me try and do it with out them and he would pay again if it needed them. i explained to him i may not get the chance to redo them. to this day i he still drives the suv.
3406B was hands down the best Cat engine ever. I also had a 3406E and a 3176. Not bad engines,but nowhere nearly as reliable or easy to work with as the 3406B. You can have everything that came after 2006. I never pumped the first gallon of that piss water into a truck and thankfully,I never will.
Back in 1977 there was an old green Chevy van at work. The guy that drove it had worked there a long time. The van used quite a bit of oil but ran well. When the engine started clicking at a stoplight, he would lift up the inside engine cover and put oil in the engine until it stopped clicking. The light would turn green and away we go. He said he had been doing this for several years. 😊
My flat tappet 4.3 has over 250000 miles and is still quiet as can be. Once that surface hardening goes..... Adios 😢 I've been told the roller lifter engines have a life expectancy of 150000 miles.
Well it really depends. You would think the flat tappet would have more failures, but I guess not. The other rollers so far have looked good, so I'm not sure.
