Has anyone installed a water/methanol inject kit on any of the small blocks (2014-2018)? I personally have the LV3 4.3L V6. Looking to eliminate the carbon build up, caused by direct injection, on the intake valves. Right now I'm trusting that Sea Foam is doing the job every 30k miles. EDIT* I'm also interested in the increased performance after tuning. I am aware that a catch can would eliminate the majority of carbon build up on the valves.
My 99 with 5.7L is really hard to start when it has been sitting for a few days (usually at least 3 days). It cranks over, but seems to run into resistance each time around. If I crank and hold it for about 5-10 seconds, it will fire, but what seems like only on a couple of cylinders, then dies. Sometimes, it seems to backfire. If I keep trying, It *does* eventually start (just the other day, I think it took about 20 tries over a few minutes to get it to start. Once it starts, it runs rough for about 10 seconds, then runs fine. I've checked the fuel pressure and it's fine (about 60 PSI),
