Engine clicking after spark plugs.

[Heardcuh]

Just installed the tune+ plugs in my 2.3, only other mod is a Cobb stage 1. When the idle settled down I noticed this clicking that I hadn't ever noticed before. Grandfather seemed concerned about it being a valve tapping against something but I don't know enough to argue that. Here's a video of what I mean, if Adam at Tune+ or any gear heads can let me know whether or not this is something to worry about id appreciate it. No CEL, did a little extra tightening beyond hand right and plugged everything back in the way it was.



Here's the vid.

Sounds normal to me. You have the engine cover off so you will hear much more noise than usual. All the white material on the underside of the cover is there to dampen the noise the Direct injection system makes. Try replacing it and starting the car again.

I did and it's seemed to quiet down. Last night the highest value I saw for Ignition correction in cyl 1-4 was 6.20 and now I've seen 7.97. I was expecting those values to be lower with the new plugs.

It sounds relatively normal to me. [MENTION=19118]Tune+[/MENTION], what do you think?

 

[Heardcuh]

Tune+ emailed me and said the positive values are okay, negatives would be bad. Thanks Adam.

Yeah, those are pretty bad negative corrections...

Sounds like the HPFP (high pressure fuel pump) to me.
Normal from what I hear.

He said they are positive, not negative.

You noticed the noise because you are in the engine bay. The same noise was there before but you had an engine cover on it and the hood closed.

I'm pretty sure you turned the car off then popped the hood. I know I do haha.

Injectors, valvetrain, vacuum pump, hpfp.

I know. When I bought my first EB last year, it made so much racket (with the cover in place, even) that I thought I had a serious case of valve tick :lol:

Happy to report that now that I own a second ecoboost, that the noises our half-diesel makes are pretty normal ;)

Get Adams custom tune and the only noise you will hear is your laugh as you giggle and smile every time you mash on the gas!!!!!!!
