My Indy thinks some vandal put something my gas tank that caused my engine to fail. What could cause a piston to crack?

 

why would you think that..and besides...doesn't you gas door lock when you lock your car?

 

We have vandals targeting us and there appears to something spilled in there ( not gas).

 

i have heard that sugar (not sure on the amount) would do that.... But like above... Did you have your gas lid open?

 

Not always locked in my gated community

 

Does anyone know for that sugar could cause a piston to break?

 

In a past issue of Panamera they talked about d chunked piston walls?

 

If you can prove that it was vandalism, you're insurance will probably cover it.

 

I read that.
I'm trying to find out what in my gas tank could cause the piston or wall to fail.

 

Ouch get a sample of the fuel tested........ if its tampered claim on your insurance.

 

I usually fill my tank when it's about half empty, which may have caused this to happen over a few weeks.

 

That sucks and good luck a used or remg engine can be expensive.

 

I thought mythbusters proved sugar did NOT do anything to modern cars.
I beleive flat6 inovations states the water pump can cause this issues by the impeller breaking down and causing hot spots.

 

I found something on an italian porsche forum... A mechanic suggested that sugar vaporizes in the chamber and with heat, it created a hard caramel like coating that would than be compressed over and over. Subsequently enough mass would be in the chamber, to crack a piston or line the cylinder heads.....

Dont know the science behind his story but it did sound possible..

 

Thanks for the help! I was told soda, orange juice and many liquids with a high enough sugar content can cause these engines to go POP!
