cracked plug hole ????????
well just a quick question to anyone who can help, ive received my head back after having it refurbished and p&p 😃 , but still worried whether its cracked all not, as ive spent 300 quid getting work done and gtting it tested. the bloke at work shop said he pressure tested it and all was ok but im still worried incase it is actually cracked. as before water was coming into no1 cylinder i know no1 and no4 plug holes a the weak points and tend to crack wen you over tighten the plugs but i cnt find any cracks evident at all ive checked from both ends of the plug holes cleaned them up and checked through out and no sign not even of a small crack. where would the crack usually be on the thread it self or above this ? im guna have to refit it anyway and hope for best after spending 300 quid getting it reburbed any opinions would be great
