Hello guys new here, so I have a 2011 volvo s60 and what happened was my air condition belt broke, shredded my other belt to the point it was spinning and cut a hole in the timing cover. After that the belt got stuck in my timing belt and caused the timing to jump. The car died while driving, we tried putting the timing marks back just in case and of course no start. At this point I am assuming the the valves touched the pistons, I dont know if it would be easier to take off the head to replace the valves or to replace the engine. If just the valves anyone know of a good place that can replace them in the boston area? thanks in advance.

 

That's a very unfortunate and rare event. However, you are where you are now.

My suggestion is to take the vehicle out of service and remove the head. Take it to a machine shop to be disassembled and checked. You will likely need to replace several valves. They cost around $20 each.

Reassemble and go on your way.

 

Do you think that there would be any other damage other than valves?

 

Usually not. But no guarantees LOL.

 

I've seen several of these cases. I haven't had one that had damage beyond the valves. We replace the head because it comes with new valves and winds up being less than new valves and machine shop work.

 

thanks guys, I am leaning towards a used engine with the same mileage.

 

I'd compare the engine swap costs with getting a used replacement head installed as well as getting the valves replaced in the old head. Expect to need all new exhaust valves.

 

Do a compression check on each cylinder. This will tell you if a valve is bent or hole in the piston. Find a friend with a bore scope and look inside each cylinder thru the spark plug holes. Double check you have the timing marks lined back up or it will not start. Make sure the cams are re-positioned correctly. Volvo has one big imagination on these. They suck finding the correct position. Lobe up or down on exhaust and intake cams viewed from position sensor end. Not sure but some models had two cam position sensors and double advance timing hubs. You can pull the head with the engine in place. Only thing if a piston is damaged. Good luck.
