timing belt for 360 5 years ?

Yes, S2K F20C is an interference engine....like the 360, well sort of I guess.

 

Essentially, every engine above 10:1 compression ratio is an interference engine.

 

i have never seen a 360 belt break but i have seen them jump teeth when they are old the hydraulic tensioner stretches the belt even if the car has low miles.if the book says 3 years i would change it at 3 years.the belt service is a lot cheaper than a valve job.you can do it through the access hole without removing the engine.I think ferrari of O.C only charged me @1900 to do the belts on my stradale last year.i only have 3500 miles on my car since the last belt service and the tensioner was out of adjustment.

 

thanks guys for all your feedbacks i will have the belts changed again in the next 6 months
