just been tearin my hair out for the past week trying to get my car to start after extractors were fitted by a local shop. (so tempted to name them here). Anyways, to even get the extractors close to fitting they had to grind away half my inlet manifold(coolant passages) and stick the pipes in a metal vice to even get them close(doesn't that defeat the purpose of extractors anyway when the pipes need to be squished). They look shi##y and my car still wont start cos they dont bolt up to the head properly. You gotta hate the feeling you get when you work on your car yourself, take pride and everything goes smoothly. But when you hand it over to someone else it comes back fu@%ed. I am now left with bin job inlet manifold. a dented, odd fitting set of extractors and a car that wont start. Oh yeah and oddly enough the exhaust shop dont wanna hear about it.
