    My latest engine mods

    This is what a broken exhaust valve does to internals... Now it´s time for a engine rebuild. Could anyone tell where to find oversized pistons with normal compression ratio?

        looks like his engine sucked one of those pesky sodium filled valves.

          That´s right. I was going about 40km/h and 2000rpm when it broke.

              Nightmare. You can order up over size stock pistons from any piston maker. Mahle should be able to help. Has it damaged the bore then?? Or do you just want to re bore anyway?

                          OMG - what a nightmare - I would be almost driven to tears if that was my engine.

                          Anybody know the root cause of these valves just self destructing - did the collets let go or what ?

                            Heat i think Paul. Running too lean. I had the exhaust valves burn out on mine with it running lean for a few months. It was mapped with a boost leak, then i cured the leak and it was running too hot Never had the valve drop off like that tho thank god
