Does anyone know if the bolts that hold the camshaft sprockets onto the cams are supposed to be replaced after they have been used once?

The haynes manual doesn't mention anything about replacing them, but it does mention that the crankshaft pulley bolt should be replaced. The cam bolts have a big friction washer on them just like the crank bolt, so I'm wondering if they should be replaced too?

I have reused them many times with no issues

If they are torque to yield then YES, they need to be replaced. whats the torque spec on the bolts? is it ___LBS ft then a ___ degree of rotation? if yes then replace it.

Not a Ford at all but, i currently have a car in my bay that snapped off a cam sprocket bolt. So, its going to need an engine. Bolts are cheap, an engine is not. Is saving a maximum of $50 worth killing shit?

y does it need a new engine why not a new cam? or head? is it a interference motor?

 

[alex62390]

Yes, interference engine. There are a few bent valves, severely scored cam lobes. missing valve retainers scares me.

and the back story is, customer got an oil change(different shop, not me), next day... boom. /engine

Doesnt sound like that was a bolt failure then but cams seizing engine still turning and braking the cam bolt
