ok girls and guys this is the thing.
i just put a newer engine in couple of month ago with 19000km on it.
it was running awesome till one day.
it started klicking kinda loud and it is not the normal klicking sound that you usually hear. it is more like metal to metal.
when i punch it in and let got the throttle thats when the klicking begans.
that other thing is i noticed that the right can blowes out weeker than the left one. when i put my hand at the end of the left can you can feel preaty hard blow but the right can is week.
would it be the exhaust valves or gasket?
any ideas?

thanks all
