I had a problem where the combustion gases were blowing past the copper washer, it was a weird fault as it gave an injector type rough running but if u switched it off and on again it was fine, what was happening was all the **** that had blown up was nippping the injector, took ages to clean the bore out!

The injectors absolutely must have the seats recut before new ones fitting other wise this blowby will always happen. The proper tool is dead cheap. Been saying this so often now, I think I should stock them in my ebay shop!!!
