ok to day i was taking a motor out and when i took the header off i found a lot of white build up on it. does anyone know whats the deal with this? should i be worried about the life of the motor?

 

It is nothing really, just deposits from the extreme heat and the cast iron sleeves, they should be about the same. The front rotor looks like it has a injector leaking or lower than the rear compression. It is just different, but anyways everything is fine with that pic

 

Cool Thanks
