Did a lot of timing chain jobs on the Pontiacs back in the day, don't remember any of them bending valves.
the ZETEC engine used in the 1999 ZX2 is a non-interference engine. This means that the pistons will not contact the valves when the timing belt breaks. Because of this, the valves will not be bad if the timing belt breaks
Yes valves can bend if the timing belt breaks.Yes valves can bend if the timing belt breaks.
an engine where, in the event that the timing is off or if the timing belt breaks, the pistons can collide with the valves and actually do damage.
yes, valves can bend if the timing belt breaks.yes, valves can bend if the timing belt breaks.
The 2.0l VIN K is a free spinning or non interferience engine.
AnswerThe 1.6L is a 4AFE engine, the 1.8L is the 7AFE engine. Everything I have read says these are non-interference so your valves are OK if the timing belt breaks.
No. It is a non-interference engine.
First off the 4.7L uses a timing chain, not a belt. Second, it could bend valves if the chain breaks.
Yes. Valves can bend if the timing belt breaks.
The intake valves can hit the exhaust valves if the timing belt breaks, so yes.
In almost every instance yes, there will be damage to the valves and possibly the piston.
?If a timing belt or chain breaks while the engine is running the engine will be severely damaged and some of the valves will probably bend and damage the pistons. A timing best needs to be replaced BEFORE it reaches the end of its life and breaks. Car manuals make this clear.
