This is something I was wondering also....

i have just been reading up on google of how you adjust actuator which is pretty simple to undersatand but no mention of how to service so is it serviceable ??

musso2010

No its not. Its a sealed unit so if its faulty you will need to replace it.

polley1979

ok dude , ill just try adjustment first. sorry for being noob but is there a way i can test to see if faulty?

hi everyone , i am new to site and i am seeking help with a running fault with my scooby that i have just purchased . the fault is intermitant . i have got a subaru impreza turbo 2000cc 1994 , its got front mount intercooler , std5 turbo,blitz fuel/boost control in car and uprated ecu,straight threw exhaust , tuned to 308bhp. from cold fault doesnt seem to occur, when driving and reaching where turbo kicks in car hesitates as if no fuel getting threw , i was told by previous owner that it is a coil pack at fault but i feel it can not be that otherwise shorly the car would only run on 3 cylinders ?? . car can been driven normal b4 turbo kicking in with fault
and fault only happens when reaching turbo . also when fault occurs you can hear air pressure noise around turbo area?? sometimes when you reach turbo it will hesitate and then all of sudden it will clear and your flying again?? also my friend matty2879 who is member was following me when fault happening and he said that black smoke come out back and it stunk . also on tick over can smell petrol fumes quit strong .

as you probably guessed i am a noob scooby owner so sorry if terminology is not correct please help with any suggestion thanks

I would check all pipes for splits. Especially the one from the intercooler to turbo and the pipes from the boost control solenoid unit.

musso2010

Just read you have a front mount. Check all connections. And also check the pipe that comes up from under the car next to the radiator fan. Mine had cracked there due to being pressed against the fan housing.

ok musso thanks mate , ill go and have a butchers now

polley1979

just been outside appears that all hoses are ok ??????????

musso2010

How did you check them? Front mounts are notorious for leaking boost. Ideally you should remove front bumper and check every single clamp and silicone joiner.

I had the same problems as you and i only found my split pipe once i had taken everything off and cleaned them up.

polley1979

yes mate just been to see a mate who is clued up on this stuff as you are and he said same thing , when fault occuring i can here aloud air leak type of noise and he said defo boost problem he also recomended i should take off pipes and check every pipe, only been on site couple of days and i am finding it spot on , and thanks again musso for you help spot on advice cheers
