This thread is to just inform people of what can happen from snapping a timing belt and to provide good information for future cb7tuners.
About a year ago, I was driving on the freeway at a steady cruising speed. The timing belt snapped and I was able to tow it home. I did a quick timing belt change and started the car. Everything seemed ok. The car had a slight ticking sound, but never got worse or changed. I contributed this to the motor having close to 300,000 miles. Boy, was I wrong.
Over time, the car began to give me issues. I was having issues with an intermittent miss and a starting issue. On top of this, the car began to bog down while accelerating from a stop and die sometimes while cruising.
These issues led me to check my spark plugs and I had oil in the spark plug tubes. I pulled the valve cover and replaced the upper spark plug tube seals, the spark plugs and wires. This did not fix the issue that I had and I kept trying to chase the issue.
The bogging down and random dying was contributed to a bad fuel filter, as these issues never came up again after the fuel filter was changed. Still, I was left with a miss that wouldn't go away and a hard start issue.
Finally, the car died on the freeway at cruising speeds. No warning, just died. When I pulled the spark plugs; two were covered with oil completely, one cylinder could hold compression and the last cylinder had a spark plug that looked like it was banged against a wall for awhile. It was bent and broken really bad.
Turns out, that I had bent the valve when the timing belt snapped. Eventually the valve snapped and rattled around the cylinder (not sure for how long). But it was shoved up into the hole where it normally sits and stuck in there sideways.
I say this to warn others... make sure to change your timing belt at the proper intervals. And, if you ever snap a timing belt, check the valves before you start it back up. I ended up swapping out the old motor and replaced it with a f22a4 with 140,000 less miles than the original f22a4.
