Random Misfires 2010 NonPP SHO, Diagnosis -- No Oil in Engine

So after those minor tweaks, I drover a good couple hundred miles yesterday. Felt smooth all over. Parked and went inside for an errand. Came out, turned on the AC at idle, Felt it get kind of rough. Another misfire cylinder 2. Starting to think it is possibly an injector issue. Was absolutely fine driving around everywhere.
 
Sure seems like it.  Since there no signs of COP failure and the plug looks ok, injector is at the head of the list now.  We have had one member document his R&R experience if you intend to DIY.
 
I will probably let the dealership handle that one. Seemed pretty straight forward on the DIY. I still have a warranty and there are a couple other small issues I need addressed.

I know it isnt ideal but will probably still take the SHO on the trip. Will keep a close eye on it. but as soon as I get back, it will be going in.

What's your consensus on running a bottle of Techron or something similiar just to see if it helps a bit?
 
cant hurt.  Make sure you put in the Concentrate Plus product, not a lesser one.  If you can get BG 44K, that would be even better. 

I assume you are running E10, so a bottle of HEET (yellow bottle) might also help, but prob take a tank's worth of gas to find out.

I ran 3 bottles through the MKS when I got it.

Costco has 6 packs cheap.
 
Usually I run a bottle of the concentrate or sometimes I will run a bottle of Guaranteed To Pass. Just depends. I will do some driving and see if I can get this tank low and throw in a bottle and see how it reacts.

FoMo, good thinking! I never think costco when it comes to automotive stuff so I will have to try that out!
 
Well, SHO died on the trip. Broke down outside of San Antonio in Kerrville. Wife was driving and started acting funny. Then it just died. Tried to restart and nothing. Had it towed to the ford dealership in Kerrville. They said when they checked, it had no oil and the motor seized up. Had an oil change the day before we left. They have had the car for a week now and barely got it on a lift yesterday. Still don't know exactly what caused the leak or if the dealership that did the oil change is at fault. Sure hope it was their fault. Will end up needing a new motor. But hey, the rest of the trip was fun.
 
Low oil light/warning came on after we pulled over and tried to restart the car. But damage was already done by then. I had no reason to believe it was low or anything because Sanderson Ford did the oil change the day before we left. I usually do the oil changes but the only reason I chose dealer for this one was so they could do the inspection and potentially flag any other issues.
 
How did a possible leaky injector change into a blown motor ... wow!  Pretty sure the oil change was not done correctly.  If it was an internal engine issue lots of bells and whistles would have gone off.
 
That's what I am saying. Lol. Pretty sure the two are not related. Only info I have right now is that oil is all over the undercarriage and passenger side and that it looks like oil is coming from the turbos too. They haven't been able to pin point exactly where or what caused the failure. I am just going off what the service adviser told me this morning. He is supposed to send me pictures some time today.

Right now it is a lot of back and forth between the ford dealership in Kerrville and the one here. The service adviser and tech working on my car are both leaning heavily towards something that the ford dealership did here either with the oil change or the ton of work I had about 6 months ago.
 
Me too. It is basically going to come down to 2 options:

1. It was an issue caused by recent work (oil change or turbos/timing chain) and Sanderson Ford will end up covering the 2 nights of hotel, towing, car rental for the trip, courtesy vehicle or rental car for time of repair now that I am back home and to either have my car shipped back to AZ or fly me out to San Antonio.

2. It will all go through the warranty. Not sure if they will reimburse for the tow but they should cover the rental vehicle for the trip and hotel. Would still need to see where I stand with everything with them. Warranty will cover a good chunk of a new engine replacement but I would imagine the cost would be less than $1k to me. Plus some other variables.

It all depends on what the root cause of the issue is. Either way, I know the next few weeks are going to be a massive headache with all the back and forth and this and that.
 
Yeah this is looking more like a timing chain issue... Especially considering the issues you were having recently and the coolant leaking underneath the timing cover. Did they verify that there was actually no oil? The dipstick will read nothing if it's even only maybe 2 quarts low... Looks like in the pic they still have the drain plug on the pan.
