who shoved a spanner into the turbo.... 
not a problembut if i do keep it i will pull the head n see what its like, but we all know the valve guides will be f**ked, so its gonna need new valves aswell.
its one ive got in for porting but it was dirty dirty so had it acid dipped and skimmedwhat you doing to it? except cleaning it very very well, are the valve seats bigger? they look massive
