4x4landy Posted July 26, 2012 Share Posted July 26, 2012 What can cause this ?? I've checked the pipes no leaks . Turbo pipes all good . Wastegate set to stock length and is a known good second hand unit fitted after mine have up the ghost from overboosting new vacume pipes etc still boosting 20+psi and not really going that good considering . Been told could be oil seal ? The turbine has no play in it feels tighter than most recon units I get in work ! Quote Link to comment Share on other sites More sharing options...
vulcan bomber Posted July 26, 2012 Share Posted July 26, 2012 Waste gate actuators got a hole in its diaphram or has seized up OR your turbo's not talking to the waste gate. Quote Link to comment Share on other sites More sharing options...
4x4landy Posted August 2, 2012 Author Share Posted August 2, 2012 I think the actuators died again second one I've fitted ... Second hand one was the last one . The wastgate is moving very easily etc gonna try hunt another actuator Quote Link to comment Share on other sites More sharing options...
ian_s Posted August 7, 2012 Share Posted August 7, 2012 can you attach an air line to the waste gate to test it? alternatively the wastegate may be opening, but it could be blocked up with soot so not venting properly? Quote Link to comment Share on other sites More sharing options...
