So i just noticed a weird kind of groaning sound coming from what seems like the crank pulley, and my timing belt keeps walking off the cam pulley like 1/2 inch. Push it back on and within 10-20 miles its in same spot

any ideas what causes this? Would like to have an idea of what to check out befor i pull it apart so my daily isnt garaged too long
Thanks!

 

I'd check to make sure the timing belt guide plates are still on both sides of the timing belt pulley on the crankshaft, and I'd check to make sure the bolt that holds the cam gear onto the camshaft is sufficiently tightened.

 

not sure off the top of my head on this year but on the newer hondas on the back of the crank pulley there is a washer its beveled the beveled side goes towards you if not it will eat the belt up and cause it to run off

 

walking off the cam?
Only thing I can think is the guide plates that go on the crank pulley. the concave sides go away from the belt.
