So, wife was driving. Got a flashing cell.
I pulled the codes had a P0351. So, I took the wipers and rain tray off to check the ignition coil... but it wasn't there....
Spark plug is also gone. Here is the best pic I could get...


So, that's beyond what I am comfortable doing mechanics wise.
How bad is this?

 

What do you mean it was gone? Like is it plugged into the harness, or the harness is unplugged completely? Did the spark plug blow out the threading? Can't tell anything from your photo

 

Since we can't see much from your pic, are the threads for the spark plug still there? If the spark plug blew out of the head I would assume not. If the threads are gone, you're probably looking at finding a replacement head at an auto wrecker, and then having an automotive machine shop check the head out and do what repairs it needs. You'd then need to find a shop to swap the heads. Costs for the repair are dependent on shop rates in your area. From what I've seen out here on the west coast- not sure about your area- used Fit engines seem to be reasonably priced. So another possibility to consider, is finding a used engine and have a shop swap them out for you.

There are a lot of threads on this site about Fit spark plugs coming loose and the subsequent damage caused when they do come loose. You might want to do a search and familiarize yourself with the issue. I remember reading some of these posts where owners tried using thread-serts to replace the missing plug threads- with basically poor results. Good luck with the repair.

 

Correct, when I checked the spark plug and coil pack were missing. No threads.
Took it to the shop this morning.

 

Let us know what happens. Hope all is well quickly.

 

It's hard to find a dude that can, but I've actually met a machinist that could weld cast aluminum.
brought a head to him from an old GM 3.1 V6 with a crack a coolant port that the heater hose hooked up to. Cleaned it up and welded the aluminum. Set me back $110.
There's still artisans out there that can repair such things, but in my experience it takes a lot of phone calls to find them.

 

If it was my car, this is how I'd repair it. I'd say there's a good chance the threads are still there though.

 

Shop installed a Helio coil. 4 new plugs and a new coil pack. Total damage $567.
I'll check the torque at the next oil change. Sitting at 30% oil life now.

 

Glad to hear you are up and running again. Update us on how the Helio coil is performing after you log some miles.

 

If it was my car I would have used Time sert to repair the threads and not a helicoil.

 

I'm glad to hear your car is repaired and back on the road. It's going to be interesting though to see what the longevity is for your repair with the helio-coil and the heat generated around it in the combustion chamber. In a four stroke engine, when you're at the end of the second stroke compression cycle and the third stroke firing of the plug, there's a lot of heat and compression right there in the area of the repair. Let's all hope this is a permanent fix for you!!
