Does it involve pouring water in the carb?
I used to see a Chevy dealer do that out behind their shop. Probably charged the customer for a valve job.
Maintaining mechanic devices require a technical and factual understanding of their workings. These qualities are not required by people commenting on said maintenance.Does it involve pouring water in the carb?
I've definitely heard this, as well. I remember watching a YouTube car guy say it's the one easy thing everyone should do to help prolong the life of your engine. My only question is just HOW LONG should I be waiting after startup before shifting it in gear? Is 10 seconds enough time? 30 seconds? A minute? Unless I was just driving the thing 5 minutes ago and it hasn't even had a change to cool down yet, I almost always give my truck about 30 seconds or so after I start it up to circulate oil and warm things up before I go shifting it into go.
This. Pretty well documented potential issue on the F-150 forums. Wastegate can stick open/closed if you make frequent short drives and never give moisture a chance to "cook" out. By either having regular long drives and/or ensuring the turbos get some regular spin ups, cycling wastegates and blow off valves (BOV), you keep things operating properly.
I recall a news report of a cop pulling a guy over going 140 mph and his excuse was cleaning out the carbon. Then there is this from the list of 50 highest speeding tickets issued in Texas, no 1 was 166 mph .
Popular mechanics says only 15 seconds for a modern fuel injected engine.
From what I have learned I would say anywhere from 10-30 seconds is acceptable. Any longer and I would be concerned about the cold start-up rich fuel mixture actually doing the reverse of the intention and cleaning off the cylinder walls of oil, as well as causing fuel dilution, as many have experienced with DI engines.
This definitely applied to 4 barrel carbs as the secondaries would rarely open. My first brand new car was a 1980 Firebird Turbo Formula. A lot of throttle on occasion would make a huge difference or at least some carb cleaner. It was also sensitive to the brand of gas, Gulf premium was a no-no, but it loved Sunoco 260!I think it is similar to the old "blow out the carbon" argument on older engines. When my dad wanted to have a little fun he'd floor it and then say "Well, I was just blowing out the carbon - you know you need to do that occasionally". If it helps justify my occasional heavy right foot, I'm good with it.
Perhaps they've fixed this. If you end up getting a squeaky wastegate you'll hear that it cycles multiple times every time you start the Ranger.
Worked on my last truck. All my friends thought it was funny. 260k and still tickling the redline daily.A redline a day keeps the carbon away!
