P2196 after Seafoam valve clean

[Conman50]

IIRC the use of additives can void the Ford warranty ?

You're the OP, I think you can.

As for hiding your sins, I wouldn't worry. Octane boosters that contain methylcyclopentadienyl manganese tricarbonyl (MMT) could very well screw up the motor but I don't think SeaFoam has it as it isn't marketed as an octane booster. Consider yourself warned? ?

dont worry. Ford dealers can "void" warranty for just about anything... new tires, shocks, oil changes, unibrow, dusty floor mats.

Truck seemed to drive fine although I may want to replace that EGR valve like people suggest.

No need to replace it until you have to. As you’ve already alluded to, don’t let this forum convince you to do stuff you don’t need.

He should run some Seafoam Cleaner through it to make sure all the Seafoam is flushed out.

ive never done it to the 5g but the seafoam treatment was great on some of my older trucks.

Inexpensive code reader/erasers won't clear a number of codes related to anti pollution devices. This said, starting about $160, most of the R/E code scanners can. The one I bought on Amazon was about $400. It isn't a $4,000 Snap-On unit, but it will clear P2XXX and P3XXX codes. It will also give you a more detailed readout, sometimes telling you what needs to be replaced and/or checked. For me, the investment was worth the expense.

What made you want to do this “treatment”?

Direct injection engines are notorious for deposits on the backside of the intake valves because they see no fuel. That code P2196 is a rich condition code. Once the short term and long term fuel trim sees the correct O2 sensor reads, it should clear itself. It's a 5 cycle read I believe.

As far as I know, no one has shown excessive deposits on this specific engine in a Ranger. That is why I wanted to know why someone would go to expense and trouble to cure a problem they weren’t even sure existed.

I guess you're right, although I have heard ecoboost engines had an issue for some models.

I swear I read somewhere a walnut valve cleaning was a regular maintenance item. I may have seen it at a dealership.

i saw a youtube video about that.

When the 2.3 EcoBoost enging gets a little longer in the tooth, the deposits on the intake valve will begin to show. It's not an engine specific issue. Its the fact that the back sides of the intake valves dont see any fuel flow. ALL direct injection engines, if they run long enough, will eventually see something. The PCV system will recirculate blow by products into the intake and when that stuff sees the hot intake valve, it's going to stick. Doesnt matter if its a Ford, Lamborghini or a Toyota .

I get the theory. Still waiting for proof it causes a problem on this vehicle and what the problem is.

Down the rabbit hole we go again

I wouldn't seafoam anything 2000 or newer

Varying opinions on walnut blasting, and videos. Personally, I won't do it unless I have issues. Just another way for the stealership to make money
