Pretty much as the title. Can you reuse a head gasket or do they have to be new every time.
Now the reason I ask is I have just done a load of engine work to a new to me 200tdi. Had a new head gasket fitted was test started and run long enough to realise one of the glow plugs is blowing. (See video on my rebuild thread: link). I have now once again removed the head to try and repair the glow plug threads. If I succeed in this today I can put everything back together again and test it IF I can reuse the head gasket. If not I will need to wait for a new one to arrive.
