2000 timing belt cam pulley broke

sup everyone,

I had a oil light coming on after few minutes of driving, checked oil level was fine, temp was fine, next day truck broke down.

Found out my power steering pump bracket drifted into alternator belt pulley cause someone forgot to put one of the bolts back on, fixed that, still no start so pulled timing belt cover off and to my horror I saw bolt had snapped off the cam and gear was laying flat against the plastic that had melt marks from the high heat, and magnetic metal shavings were covering everything.

Before I tear everything down was wondering if anyone had any advice on how bad the damage is, and how many parts I would need. Already figured new timing belt kit, gear pulley and bolt, but also may need new cam and who knows what else lol.

Thank you for any help or advice.

 

The hardest part will be getting the broken bolt out.

Was the timing belt just done with cam seals so it might be possible that bolt was never torqued ??

What bothers me is what caused it to snap?

Did you just buy this truck ??

How many miles ??

 

170,000 miles, have had the truck since 50,000. Timing belt was done around 70,000.

Yeah have no idea if it will be possible to drill and tap bolt out.

 

new motor

 

I was thinking along the route of a different engine .

Why I asked the mileage .

Being the Cam is a rotating assembly it has to be perfect

Really hard call used engine or try and fix this one

 

Thank you

 

It looks like you'll definitely need a new cam. Problem lies with what the inside of the head looks like. Valves, bearings could be shot. Could also be great and nothing happened in there and a simple cam swap, in which case I'd do new bearings and seals. It will take some investigation for sure but maybe a new head(s) instead of a new engine. Tough call. Sorry to see that. I wonder what happened there too. Thats an odd failure.
