Cam Leak FIRE!

Sorry for your loss. Glad your ok though. I got some cool dental tools that will fix that right up.

 

Sorry for your loss and thankful everyone is ok. It is a hard thing for anyone to endure.
After 23yrs in the fire service, and still showing up for my shifts, I have learned that you can never discount anything. As soon as you think you have things figured out, something will throw your head spinning again.
Could it have happened from the leak? Absolutely. A combustible near an ignition source....
Did it happen from the leak?
None of us could say, with any certainty at all, either way.

The folks who investigate cause and origin spend hundreds of hours learning their craft. Lecture, book work, practical exercises and even lighting stuff up just to see how it burns. Most of the knowledge used to make determinations is based off of experience in the field, with a little common sense and gut feeling thrown in. All to make the most educated guess you can. That’s the truth of it.
Vehicle fires, to the extent of this and worse, are some of the hardest to pinpoint, because as has been said already, the damage caused. Yes, you can test for accelerants, such as gas and oil and petroleum products, but what do they run on??
I do not claim to be an expert at anything in this life. Just my $.02.
I’ve seen engines soaked in oil and run forever, but I’ve also dumped a lot of water and dry chem on things that made no sense at all. All that matters is that no one was hurt.
Toyota will not fix the cam leak issue due to the extent of the monetary damage the would have to endure. We, myself included, will continue to watch our beautiful trucks weep oil, or shovel out the money to fix it ourselves. I fought down every avenue I could for a remedy, then ate it.
