turbo on a d16y8. dsm injectors..
my o2 sensor went bad two days after the turbo went on, engine blew on way to dyno..

new bad *** d16y8 forged internals all the goodies... new o2 sensor.. car has been ran... babied! (break in) just taking it real easy till its broke in so i can dyno it... o2 sensor already has gone bad.. why does this keep happening.. those freakin sensors are expensive.

am i too rich? to lean? bad sensor placement(located after turbo, just before the cat, stock location) bad computer giving false codes? stock computer..
do i need a special sensor because it is boosted now?

 

coolant will kill one quick.just a suggestion

 

no coolant i have been watching this motor inside and out since i the first time i started it.. the block and head were both decked and ARP bolts hold them together... no water is getting through there all water and vac line are hooked up right so now water in the intake manifold...
