Interference Engine

It the SVT motor an "interference" engine? In other words, if the timing belt breaks will the pistons contact the valves?

I just bought mine. It has 38K miles. What should I be checking for wear wise? I pulled the coil cover yesterday and it's filthy under there. The engine was really clean externally. It has an aftermarket battery and there is some corrosion under the battery box. I ran a Carfax on it and it came back clean. A one owner , California car. I installed my first mod yesterday, a week after purchase, a Steeda CAI.

a mechanic told me that if the timing belt broke , you would just be stranded on the side of the road, but nothing would happen to the engine.

if the timing belt bropke on an svt you would be screwed because it is an interferance engine and the pistons will hit the exhaust valves i believe. but i know that if it brakes most likely you will screw up the engine!

Yes it is an interference motor and everything will be pooched if the belt breaks. I talked to Ford and it's rated at 180k km (100k Miles) and most people replace at 80miles because of some people finding that it will break early. Check for cracks, etc. in the belt on a regular basis will show you the wear & tear... replace if there are a lot of cracks in the rubber.

Its is an interference engine but it doesnt mean that if the timing belt breaks that your engine is done. Depending on what stroke its in then you might be good.
