As a previous post my Cambelt tensioner failed causing the motor to lose compression. Anyway stripped heads off and 14 of the 16 valves are bent and all four pistons have small dents but no cracks. Also a head bolt sheared off in the block!! Thing is the bottom end is forged was tempted to re new and re seat the valves and freshen up the engine. Just worried about the pistons and is it worth it.... Anybody got some forged pistons for sale lol[URL=http://s441.photobucket.com/user/craigwrx277/media/DSC_0204.jpg.html]

 

 

Bin the lot and build a fresh engine. No telling what damage has been done. And that sheared bolt sounds like fun to extract.

 

The machine shop at my work will be able to sort out. Was thinking of splitting the block and just sorting it.

 

Fair enough then, might be better off sourcing another set of good heads. Those might need new guides as well as the valves replacing.

 

The piston crowns are normally ok, have dressed the valve impact marks out before on an engine which had similar damage.
As for the valves, you could go for Supertech replacements or phone around the specialists ( API, Scoobyclinic etc etc ) for a good used set - all depends on your budget tbh.

beware big ends - change them

as above valve guides are probably done

 

The engine is an api one but yeah think a good going over is needed.

 

Not that .when the piston strikes the valves a shock is sent down the con rods and can squash the big end shells
