Hi all! I removed the fuel injectors on my 2017 Santa Fe 3.3 v6. 120k miles. Number 1 and 6 injectors were leaking, diagnosed by the dealer and my nose. I could definitely smell it was running rich. The dealer wanted $2800 to replace all 6 injectors and replace the spark plugs. Too much for my blood, so I'm sending my injectors out to be cleaned and rebuilt.
While the intake is off and the valves exposed, I'd like to clean the carbon buildup off them the best I can. I won't be walnut blasting them. How should I go about cleaning them up?
My thought is, rotate the engine til the valves are closed. Spray something on the carbon to loosen and soften the buildup. Let it soak then agitate. Suck out the slop with a shop vac. What would you recommend for the spray? What would you use to agitate and scrape the carbon?
I'm going to replace the spark plugs with factory iridium's or the new rutheniums. I'm leaning towards the ruthenium for their longevity. Maybe they improve performance a bit, but won't be able to tell too much as the cleaning of the injectors will make more of an improvement to performance and mileage.
Any thoughts about replacing the up stream O2 sensors? Especially bank 1 as it's much easier to change
I will take pics when I get back to working on the car. Thanks for the help!
