what if...

[LUIGI-3]

what if cambelt breaks on boxer? would Pistons hit valves? or are they made that the engine just stops?

[Gambit]

If it snaps chances are would be it's killed it , so yes piston meets valve. Big repair bill :)

ok fair enough, cos i heard that some engines have some clearance that if it breaks they dont meet, just engine stops.

Subaru engines are interference engines, which means that when the timing is out (or belt breaks) the pistons and valves will hit each other.

 

Some manufacturers engines are non interference but Subarus are.

And 2nd what Tlag put. Some you can snap them get a tow fit another away you go. But as I said all expensive woman if they break a heel you carry them or pay for a taxi ;)

. as above . no clearance. and f you are thnkinkng of changeing the belt then make sure you buy the full kit. belt, all the pulleys and the tensioner as i have heard storys of pulleys failing after they have been took off and put back on again. not a cheap job but i did mine mydself and it still cost me around 200 squid for the bits alone

Cam belt is doable but a real pain in the **** when the engine is in the car. My engine was out and I tried to do the cam belt myself, didn't buy the full kit just a new cam belt. When I fitted the new belt using the old pulleys, it was about half a tooth out on one cam. When I put it back in the car the engine ran but was very lumpy and luckily it didn't cause any damage, ended up getting the belt replaced by a specialist. Cost me £300 all in, the whole cambelt kit and fitting.

Not bad price that Pete for a full kit and fitting.

That's what i was thinking. :D
