Just been out in my car (2ltr ZVH), now once it had warmed up, it was running fine (as usual), running upto 15psi, but after about 10mins, the car felt really slow, and is only boosting upto about 5psi? If i keep my foot down, it goes up to about 10psi but takes an absolute age to get there? What could it be? Ive got all samcos etc so dont think it will be a split hose?

Please help as im supposed to be running at santa pod at the weekend!!

 

It sound's like one of the following:

1) A blown hose or similar.
2) Leaking dump valve.
3) A dead Amal valve.
4) A dead turbo.
5) fault with wastegate

 

Cheers Stu, the turbo is still spinning though, is tha ta good sign? Aint got a dump valve, so cant be that, where is the amal valve? Ill check the hoses now!!

 

broken wastegate/actuator?

 

I thought that, how hard are actuators to take off/fit? My mate has got a -31 on his turbo that i may be able to borrow??!?

 

amal valve is ontop of the gearbox, circle thing with 3 hoses coming off of it, hoses goto airbox, turbo housing (or crossoverpipe, depending on how its set up) and wastegate actuator

also has 2 electrical connections on it.

unless ofcourse it has a bleed valve fitted betweena hose running from turbo to actuator... in which case ignore the amal valve coz its been bypassed and its not your problem

 

Pretty sure its got a bleed valve on it Jim,

Anyoen know of anywhere in the notts area i could take it to get checked out??

 

acutator has come loose 100%

 

notts? aint jamsport near there? they know their RSTs

 

How do i thighten it up mate??

 

Jamsport are in Northampton

 

to roughly check your actuator, get a pair of pliers on the rod or the wastegate and try to push it towards the actuator. the spring inside should work against you and be quite hard to push. how hard is hard, and if it's hard enough to give you the required boost is hard to say. check to make sure that the bracket isn't cracked or flexing or anything.

 

If actuator comes off you cant make ANY boost at all...

 

Where do i tighten it up?? Ive had a look, but cant see??

 

with the 2 bolts on the actuator lol you will see you have my no kev call me n ill tell u

 

Ive sorted now Gus i think, it wasnt the 2 nuts, it was the actual bracket that hold the actuator in place!! Cheers for the offer though mate, i might ring you again if anything else goes wrong!!
