The condision of the chain. At this point in the life cycle of the 403/455. IS NOT the problem. So. The cam will be running a few degrees retarded. There isn't one of us that would ever pick this up the performance loss from our engine. Even if you get 200,000 miles on it. And the chain jumps a tooth. That WILL NOT destroy that engine. It will still get you home. The BIG problem is the aging of the plastic teeth that are on the cam sprocket. Plastic cracks with age. Not miles. A failed cam gear WILL DISTROY you engine. PIRIOD. Every engine will be running perfectly just before that sprocket fails. Here's the two choices. A $60 sprocket/chain replaced while at home. Or a complete engine rebuild somewhere on the road. It can be checked out with an inspection camera. By removing the engine fuel pump Bob Dunahugh
