Get the CRC GDI IVD cleaner.  

 

It's better or different than the Seafoam treatment? I have the Seafoam stuff already, but if CRC is better I'll do an exchange

yep, gotta admit the scraper is genius. Probably more reliable than the wife. DEFINITELY less mouthy about the situation.

I just did my truck with seafoam. I can't tell a huge difference yet, but we will see over time. Used my window scraper to keep the rpm around 2000.

Ok, so lately I've been noticing the 6.2 stumbling a bit, hesitating, lower mileage - even more than expected for winter - etc. and began getting more concerned about intake valve buildup. 26k miles

Man, my driving is conservative, 85% around town and my 5.3 with 21,000 miles averages 16mpg.

Perhaps going 80+ on the highway doesn't help but still ... figured I'd do a touch better.

 Awesome thanks for the info, I appreciate it. I'll be looking into this method as I have 30k miles on the truck, no preventative maintenance/mods done in regards to this buildup.

 

Do you have any pictures, before and after?

Unfortunately, no I didn't take pics.  There've been a few users on here that have taken pics with trucks in the 40-60k mileage range.  It basically looked like that so I didn't see the point.  I did spic n span on the first valve and port and after that said screw the port and just did the valves lol.  It was taking alot of time.  Not to mention, the back 2 valves, if you don't have a borescope, you have to jam your head in an inch from the port to look inside.  Not fun.

The CRC is made for the exact issue this thread is about: oil coking/buildup on the back of direct injection valves.  Its like a couple bucks more than the seafoam aerosal.  Just get it.

That's why I love this forum! I will do that. Does the CRC product come with the same type of applicator straw like the Seafoam product?

If you take the intake tube off, you don't need the straw.  Just hold the can in front of the throttle body butterfly valve and spray away.

I did this a couple of weeks ago with 56,000 miles on my truck.  I can't really tell a difference around town.

Doing some research online and I see quite a few posts from people who say not to spray any type of cleaner into the engine as it has a good chance to cause damage to pistons and cylinder walls from large pieces of crystalized deposits breaking off.

 

What are some of your guys' opinions on this?

I wouldn't and wont hesitate run a cleaner thru the intake when the time comes. The carbon wont hurt anything unless you do the clean then run in V4 mode running it thru. My thinking is that part of what makes these engines so powerful is their ability to move large amounts of air thru the combustion chambers. This means that exhaust evacuation and scavenging works really really well. So when the exhaust valve opens does anyone believe that tiny bits of relatively light carbon wont get sucked out of the cylinders?. And of course the catalytic incinerator underneath wont have too much trouble digesting what comes thru either within reason. $.02

That was part of the reason I decided to manually clean.  I was concerned about too much junk getting sucked into the cc.  Would CRC/seafoam/etc be effective enough to do this?  I don't know and I honestly didn't want to find out.  I can tell you while the non-afm valves were lightly coated with sludge, the base of the afm valve stems were completely caked.  It was hideous.  Easily took me 3-4 times as long to completely clean.

Self cleaning oven that turns carbon into dust = 900-1000 degrees

 

catalytic converter = 1200-1600 degrees

I thought I had read somewhere where an oil change is recommended after doing this?  Can anyone tell me if this is true?  I just had an oil change but I would like to try this.  

 

Thanks

If you want a really great cleaning look for a shop that offers BG Products services.  They actually force cleaners through all the major systems using special equipment.  If you have it done regularly they even have a warranty on the serviced systems (fuel, trans, oil, steering, brakes, etc. depending on which package you get).  It can get a little costly but if you are keeping the vehicle for a while it is worth it.

 

You can also buy individual bottles of some of their cleaners and put it in the system by yourself just like Seafoam, CRC, etc.  This doesn't do as good a job as the Professional service and doesn't carry a warranty but it still helps a lot.

Haven't had a chance to do the CRC yet, but I'm gonna do it soon, hear good things. I think the VW guys have it the worst with the GDI engines, and I assume our problems will be similar even if slower

      upgrading speakers on 2026 std cab WT...

      By bwiese · Posted

      I don't wanna do major surgery/upgrades, behind-the-dash work, add amps, change radio etc. on my '26 std cab WT. On the WT, it has the base 7" IOR infotainment setup, and only two speakers (doors). Since I listen to classical, looked around for speakers that do well and dug thru reviews. Two-way speakers were found to be better than 3-way. So I've ordered a pair of  Infinity Reference REF-9632IX 2 way speakers.  [These may  or may not have been discontinued / succeeded by the 3-way ...9633 ones.]    These speakers are lauded for 3 ohm and 94db sensitivity spec so they'll work well for ordinary base car radios without amps and offer better performance (quality,  strength) than  default base paper-cone speakers. They'll be installed in a few days and I'll let y'all know what I think. Bill W San Jose

      Thanks!   Changed out the rear shocks today to Bilstein 5100s.  So far feel much better. The stock Rancho were wore out.  Lots of heavy hauling (2 moves, home renovations, etc).  Next up is new BFG tires Monday.  Cant wait the current tires have little to no wet traction and are super loud (hum)

      Ok, I got the all the codes. What do you all think would be a place to start?

      Correct way to service 2024 l8t allison trans?

      By Chuck FB · Posted

      How about I just point to the factory pans stand pipe little drain plug and claim its a pan with a real drain plug !. I just couldn't swallow the fact that a Dorman pan which at this point is probably the only pan out there that fits the gas version truck cost that much up here in Canada so I decided initially anyway to skip it and see what I thought of pulling the pan method and down the road if I felt inclined enough then I would either install a drain plug kit in the factory pan if there is enough room for it, or have a bung welded onto it, or put an aftermarket pan on. The thing is if the pan is not pulled then the magnets in the pan can't be inspected and cleaned or if wanting to change out the filter. However of course it certainly would make the job easier to be able to drop the oil first before having to handle the pan if dropping the pan that go around was the goal.    I knew a guy locally that was doing custom field spraying years ago with a pickup pulling a ground driven sprayer, I believe it was a GM pickup with an automatic trans. He had a drain plug in his pan and would drop the oil out of it once a week and top it back up through the dipstick tube to keep refreshing a portion of the oil often and that made the transmission last far longer than had he done nothing. Soft fields pulling 500 gallons of water at the start of each mixed up sprayer tank batch and in low range sucking along. I imagine he got some tips from other custom sprayer outfits doing the same thing at the time and learning from their blown up tranny mistakes. Transmissions then had no lock up converter so would cook the crap out of the fluid slipping that much and it would not have been synthetic fluid either.
