andrew......

has anyone else had some thing like this happen. there is no visual damage. but for the amount of air escaping you would defenitly think there would be a big hole somwhere. the only way it could be coming out where it is is if the valve was open an the air would pass by the stem seal which i wouldnt it would go rite out the port that was open... so valves are 100%closed. ill have to just get it looked at down at the shop. will let yous no how it goes

hi guys an girls.... so i have a rb25det non neo that is leaking air like a sift from number 5 cyl/chamber. its coming from inside the head behind like the cams an sprigs at first thought it was leaking out a valve so checked that they were closing properly an they seam allgood double checked the valves were not opened by the cams or anything silly . so could there be a crack anywhere in that chamber that is not visable to the eye but big enough to leak alot of air
