Also known as a interference engine, A zero tolerance engine is an engine that would damage the valves and likely the pistons without correct timing. This would occur because the valves and piston have the ability to come into contact with each other. With correct timing, this is not an issue because the piston travels away from the valves as they travel into the cylinder. When timing is lost, the piston could travel toward the valves as the valves enter the cylinder, resulting in severe damage to both. This is not an issue in a non interference engine because the piston and valves will not contact each other if timing was lost.
The 3FSE engine is not an interference (zero tolerance) engine.
No. Nothing is zero tolerance if you measure to a great enough precision.
No
No
yes
if by zero tolerance you mean that if the timing goes the valves will get bent then yes it is ^ that is wrong Non Interference is that term and your engine IS NON INTERFERENCE !!
Yes
yes
no
Yes
The 2001 PT Cruiser with a 2.4 liter engine has a zero tolerance or interference engine. This means that if any of the timing components fail, the engine itself will because severely damaged.
Yes.Yes.
