My guess would be the high pressure oil rail leaking.

Ive had two HP rails fry out the main oring at the base of the rail... also not sure if they still supply the kit with three diff. Size ring sets depending on the thickness of the ones on the rail... but be sure to size them up carefully! =)

Once i pulled the rail, 4 of the 6 orings were either blown out or cut into,the backing rings were also melted, bus runs great now
