2008 F450 with 6.4 litre. I filled the tank with gasoline by mistake and drove it home. (10 klicks). The next morning it started like crap and I realized what I had done. Towed it my mechanic who claims there is no compression in 2 cylinders. Apparently I have to remove the cab in order to pull the engine?!

a) Is it possible to lose compression due to gasoline?

b) is it really a $6,000+ job to pull the power plant?

c) if a and b are true - does anybody want to buy a truck with no compression on 2 cylinders?

 

Need to give more info on yer vehicle...

So the experts here can help...

Me, I'm no expert... but I drive a 6.0

 

Not sure what more you need. 6.4 diesel 2008.

 

If you've gassed up your engine and ran it 'till it began to run the way you describe, EVERYTHING in the high pressure fuel system requires replacement, as well as all low pressure fuel system components flushed of all residual gasoline. This means your HPFP, all eight injectors, all high pressure fuel system plumbing will need replacement.

How has your mechanic determined you have no compression in two cylinders? Has he run only a relative compression test using only a scan tool, or has he actually run a manual compression test which reads actual individual cylinder compression psi readings?

For what it's worth, I just happen to have a 2008 F-550 6.4L in my bay right now that I just replaced the engine with a complete Ford drop-in unit back in January. Only 118 kms. and 15 hours later, it arrived back on the hook last week with a badly leaking HPFP, leaking fuel internally into the crankcase that caused the engine to run away. Three consecutive relative compression tests via my IDS scan tool indicated issues with cylinders #1 and #3. However, before Ford would authorize a service replacement unit, I was requested to take manual compression readings on all eight cylinders which immediately revealed cylinder #1 100 psi lower than the other seven. The point being, a manual test will yield much more accurate results before you make your decision.

In any event, replacing the high pressure fuel system components alone, is not going to be a cheap affair either.

 

consider this.

If one purchases bad fuel and such fuel causes damage to your truck and one has comprehensive insurance coverage, many times such insurance will cover the damage.

If a gas station puts gasoline in the diesel tank and you used the right pump with the wrong fuel thereby getting gasoline instead of diesel your insurance would likely cover the damage.

Now, I do not know if one's insurance will pay if one pumps the wrong fuel by accident but such seems to be an "accident" just like running the truck into something and killing the engine.

Might be worth it to check with your insurance to see.

Also, one can put rebuilt 6.0 engine for about $7,000.

How much?
What exact kind of truck?
