hey there i was driving the other day on the highway and i felt a jerk in the car and i looked at the speedo i was losing rpms and speed on the highway.

i pushed it to the nearest town so someone could take a look at it,

a week later they said they found anti-freeze mixed with the oil and there was metal chunks in the sparkplugs

for some reason i believe it was my timing belt that broke, and it destroyed my block, head gasket and pistons and valves... but i kept reading about the 3G-SE engine and they said it was a Non interfered engine?

i dont know what that means

but it would be helpful if i can hear your review of my situation

non-interference means that if the belt snapped no damage to the engine would occur.

To your problem, don't know what killed your motor when you are just driving of the highway. Don't think a blown head gasket will do that. It will run bad and blowout a big puff of white smoke before dying. Usually something electrical snap to kill it.

Timing belt will do it also, but don't see too many snap just cruising along the road. And I would think you can hear the broken belt fap around a little while. Can always check if the cam lobes are moving when you crank the motor over; though the oil cap.

Can check the obd blinking lights.

what that means is if a valve is at full lift and a piston goes through TDC, there is no collision.

both the base engine and turbo version configs in this are non-interference type.

so tossing a t-belt alone won't cause the damage you've incurred.

what ever you do, don't turn the crank. just cause more damage. never know, it might be salvageable. wouldn't count on that though.

but i think either you dropped a valve or tossed a wrist pin or a con rod. have to tear it down to know for sure.

i wouldn't bother pulling codes. you already know why it wont run. internal engine failure!

besides, since it wont start, likely get more codes than are relevant to your issue. and it wont itemize a ring, piston, con rod, etc........
