Iowa | i can tell you this. if the timing belt breaks the valves hit the pistons. they are made to hit flat so usually you have to replace some push rods and rocker arms. i would say about 1 out of 20 will bend a valve and if you dont fix it and keep running it chances are it will drop a valve and ruin a piston. engine has no sleeves but you can bore the block and install sleeves. you can get a kevlar timing belt and run it 5000 hrs. the belt only costs like 170 bucks. but the tools to install the belt are around 900. the belts that fail are mostly because an oil leak will get on the belt an you know what oil does to rubber. | |
