4AG ENGINE.......GONE(*_*)

Got terrible noise from engine after went to race track............sounds like bearing but.may be another problem too?

This engine from AE86 stock body, NA1600cc no oil sump baffle,oil cooler , no fuel sarge tank.....basically normal body with high performance engine.....

As we expected.......

NO4 big end bearing is gone......



Head is looks okay..but there is the sign of detonation........

According to the driver....it's happened end of the session...... with bit drifting!!????

It's seems not only oil sarge......but.....fuel too!!!??


Next engine will be more power..........look for good oil sump.!!!
