Next thing you should do is drink some of that jet fuel and try to light your **** on fire.Or imagine the farts.So many more things you can try with jet fuel.Maybe put some on your weed and smoke it.Maybe put some in your furnace and heat the house faster.Or maybe not have a vehicle and walk around trying to look cool as the guys drive by you laughing and pointing at the guy who put jet fuel in his truck.You're awesome.

 

I think we found the next canidate for bannism

 

Ok, Stop. You say jet fuel. Thats more refined diesel basicly. Now that wont work in your truck. Trust me. But now I can see 100LL. Thats at most if not all small airports. Im not sure what would cause the problem though, Did you run straight 100LL? I've seen people, including my dad(who is also a airplane tech. at our local airport.), run this in there trucks just straight, no problems. Im just wondering if the high octane and the lead in it has f'ed with your pcm. Try reseting it. Then check, gap, and clean all your spark plugs. Personaly I would pull your o2's out and clean them too, Just because of the lead.

Good luck,

if you ran it that hot you may have blown a head gasket, cracked a head, or cracked the block.

Now if you did one of them you would lose your vacuum pressure which would make it run like junk, and your plugs wouldnt tell you anything.

 

this is a very small arport it has 2 big above ground tanks and on the side it says jet a on it and it has a texco sighn next to it. and yes i ran about 4 gallons of stright jet a fuel.

 

Dude you overheated your engine. Your gonna have a blown head gasket(s). That white colored smoke means your burning coolant. The blue smoke is burnt oil which means you probably toasted your rings. Remove your radiator cap and look at your coolant. I bet it looks like a milk shake. Also check your oil level might be over full. Probably coolant mixed in there. Your going to need a new engine.

 

Back when I was a kid my Dad used to take me to the dragstrip (airport) and race his '54 Ford (292 V8 with 3-2B carbs), and we fueled it up with avgas. If I remember right (40+ years ago) this stuff was like 118 octane. Not jet fuel, but it ran hot and he was constantly rebuilding the 2 engines he swapped back and forth. Sparkplugs were for 1 run only! I remember seeing all kinds of warped and damaged internals.

I didn't even think a sparkplug would ignite JP.....

 

If it was a 318 he wouldn't have this problem
