Hello all,

Finally got my EM1 out of storage for the summer, and went for a little drive. Came home and noticed my white valvecover has a "burnt" spot on it where the timing belt is located. We pulled off the valve cover and side timing belt covers and some how the timing belt moved a good 1/4 inch or more and actually rubbed grooves into the side covers.

Needless to say I ordered a new timing belt, but what could have caused this so it doesnt happen again?


Thanks,
Justin

Edit for pictures!

im amazed that every cell phone has a camera and people still dont take pics when they post a thread like this.

Sorry that im at work and car is at home. Plus what would you like a picture of? the rubbing on the valve cover? All you needa say is if there is to be a guide for the timing belt not to move or not. No need to be rude

where exactly is it rubbing? on the intake or exhaust side?

Its rubbing on driver side. The belt has literaly moved off the cam gears a good 1/4" and seems like maybe there should be a guide to keep it pushed fully onto the gears?

As mentioned, pictures are always helpful.

Sounds like the belt may not have been tensioned properly or the tensioner is bad.

But is there anything that keeps the belt straight on the gears besides the tensioner? I know some cars have a washer on the crank pulley that keeps the belt from moving off the gear.

Former User

No.

Post photographs.

This is the timing gear right behind the crank pulley. Is there to be a concave washer on both sides helping guide the timing belt?

Former User

Yes

you should have 1 washer on the outside of the belt.

If you look at the pic RonJ posted it clearly shows 2 washers for each side of the belt

The factory service manual diagram I posted above is for the 99-00 Civic Si B16a2 engine.

However, the diagram at Majestic Honda shows only one guide plate located on the engine side of the crank gear:



My guess is that this^ is correct.

Your right it depends on the timing gear
