I have a friend who is having problem with a head shop?

Ok so a friend of mine picked up a new cylinder head for his car and took it to get cleaned. They did all the work and everything was fine. A few days later he took it to a head shop to have it put on his car. After he picked the car up no more than 3 days later he noticed the car was leaking oil out of the head under the spark plug. When he took the car back the guy stated that he had a hairline crack behind the spark plug. Now my question is my friend said when he pick up the car he noticed the head was a little dirty( he figured it was just some oil from the guys hands and thought nothing of it and cleaned it). Im thinking that when he went to get the head pressure checked he noticed the leak and tryed to clean up the engine. But my point is isnt every shop supposed to check for any leaks before returning the car back to the owner of the vehicle? Thanks in advance guys

the shop should have for a crack and if they did find one and didnt told the customer then its the shop's fault

behind the spark plug as in where the lower tube seal would seat?

[eastern_ethics]

yes there is a seam right along that part that has a hairline crack

[wed3k]

did you notice that before?

is it the same head? if it was tested and worked on before shouldn't the machine shop have brought that to your attention?

yea he called the machine shop and they said that they would have caught if there was a crack in the head so im guessing that the head shop overtightened the head and crack it...cleaned it up before he came to pick up the car and just sent hime on his way (shady people out there)
