    Yes, GM’s Top Engine cleaner is what a dealer would use also sold as ADCelco X66P. Most engine degreasers have Diesel as the number one ingredient. I would suggest throttle valve cleaner, Berrymans B-12 Chemtool and as mentioned a bottle brush. Never throw away a tooth brush because it goes into the garage. Also, a lite coating of a silicone paste lubricant on the injector o rings will allow easier installation and if you want your rubber door / trunk seals to last longer, use it there also. It’s listed in the owners manual, like page 1,534. LoL. Kent p/n K-44 comes with a brush applicator, or at least the 5 cans I have do.
    You can leave the injectors attached on the rail, seals remain undisturbed and makes it easier to install, at least for me.
    I have seen oil catch cans with just an SOS pad inside. This scares me and would install a small inline low pressure fuel filter under it on the return side. A automatic or P/S filter works well also. Just a belt & suspenders approach while thinking out loud.

    coupla comments respectfully: you push on the metal clips to remove the connector to the injectors. The part at the back of the manifold is the Mass Absolute Pressure sensor. The Oil Pressure sensor sits right behind that on the block.

    That's not nasty, lol.
    I cleaned mine a few months ago, and it had about a half inch of hard carbon coated all around the inside. It had a small crack in it, and so I finally picked up a used one today, and it had the same half inch coating of carbon. This one looks spotless in comparison!
    Good video though, I'm currently soaking mine in old engine oil to loosen up all the crap. Then I'll do the dish soap, then a bit of scraping, then probably a last clean with dish soap and degreaser.

      @@20tea Mine was missing a little piece of plastic that jutted out to hold on the air filter housing, and so there was a crack maybe 2cm*2mm, and it had oil running down the back of the engine block. The car ran OK, but never ran great, but that didn't change at all when I got the new manifold.
      I only ended up replacing the manifold because it failed the NCT (MOT) test, because the air filter housing wasn't securely attached!

    Acetone/brake cleaner/carb cleaner will eat the plastic. Simple green and dish soap won't touch the gunk. You need parts cleaner or diesel fuel. Fill a tote with about 8" of diesel. Soak the intake. Then use a soft wire brush to clean it. It's a messy job.

    Always replace gaskets when your swapping an intake. Dishwasher method works the best with high heat cycle. Engine degreaser leaves a greasy film. You don't want that crap in your intake. Replace that TB gasket as well. Also, make sure the guys that are installing that or if your doing it yourself, grind down those ribs on the intake and smash down the steam tubes a little on your engine. I have a video on what I did on my channel.

    • @jefflammers2712
      @jefflammers2712 2 года назад

      If you are replacing an ls1 intake with an ls6 intake you should use the ls6 style steam vent lines. the rear two are just block off plates and the front two connect together and then go to the throttle body heat crossover unlike the ls1 steam line spider that connects to all four places.

    did you have any complications as a result of this? I cleaned my intake in a similar fashion (as well as injectors using a different process of course). after putting back together i hydrolocked a cylinder and blew my motor. I though was broken injector flooded cylinder but maybe was water that didnt come out of intake?

    • @mycorvettelife
      @mycorvettelife  4 года назад +2

      No I didn’t. You definitely need to make sure it’s 100% dry. Water can get trapped in the runners. Blow it out with air.

    • @matthewjeschke
      @matthewjeschke 4 года назад

      I really think my hydrolocking was due to stuck injector in the end. I also left the truck to prime the fuel injectors for a couple minutes. Had been super careful about drying the intake.

    • @FTsingos
      @FTsingos 3 года назад +2

      @@matthewjeschke I can't be 100% certain, but I'm pretty sure it was a broken (stuck open) injector and not a wet manifold. I assume you shook out most of the water, dried it somewhat. It takes quite a bit of water to hydrolock an engine. More than a damp intake. Are you sure it's hydrolocked and not another reason it seized?

    My 2015 Silverado 1500 6.2 just bent push rods on cylinders 4 and 7. Doing a AFM delete. 117k miles, got it torn down now, and the intake system is filthy. I've torn down many engines in my day and this is the absolute worst by far.
    I've kept my oil changed and treated the truck well. Didn't use vast amounts of oil, maybe a half quart between changes. If this is by design, it's a piss poor product. The combustion chambers were so bad I can't believe the injectors even worked. Piston tops, intake ports and valves are nasty and I've done the intake valve cleaning procedure a couple times. This is my first experience with a LS/LT based Engine and I'm not impressed. My LT5 in my 1990 ZR-1 is damn near spotless after 80k miles. I love my truck and the engine actually ran great until the lifters expired.
    I'm adding a catch can maybe two, I have to clean this up. The cylinders look great, can still see the honing marks on the walls. I feel like with the new BTR cam, ls7 lifters and cleaned up intake system the engine will live a lot longer. GM needs to go back to the drawing board on this. I guess it generates more business for the service department. They wanted 8k dollars the put the junk lifters back in, I'm doing the delete myself for a fraction of that.
    Sorry for the rant, good info in your video, soon as I get the heads finished, will be intake time. 👍👍🏁🏁

Steve Harris and the cops came along and hauled me off to jail and I still don't know what for..😇. BTW do not trust the Dorman knock sensor kit. Im in the middle of doing it the 2nd x around as they crapped out AGAIN after only 3200 miles. Its the number 2 fix on GM 5.3s and its ridiculous to have to remove the intake for the R&R.

      I've owned my C5 for 17 years and cleaned the manifold several times. Soak it in Simple Green and hot water over night (be sure to pace it upside down so no air is trapped inside), then use a linear nylon wheel brush with an extended handle to scrub inside while agitating in the tote. Do this several times until clean. Discard cleaning solution where it doesn't pollute the environment.

    Hot water works better. It helps to melt the grease. fantastic, 409, or like type cleaner does a good job, finish it off with dawn dish washing liquid, it also helps get rid of the grease. I worked at an engine shop many years ago, we used all kinds of household cleaners after the parts came out of the Hot Vats. Tide does a good job of breaking down the grease. This seems crazy, but after spending all that time cleaning parts to get rid of oil and grease, we sprayed WD-40 on machined surfaces to keep them from rusting. Try to avoid aerosol cleaners, I have problems with my lungs from many years of using these products.
