ashbuster Posted March 17, 2012 Share Posted March 17, 2012 (edited) hi guys not sure if this is normal but im guessing it isnt i took the car out for a spin after putting the turbo hoses back on and i had a leak so i took it back home and sorted the jubilee clips out and i gave it some to see if i had a leak, it boosted to 1.25 bar as set in the boost controller. so im guessing i have no leaks but when i got the car back on the drive and shut the engine off i lifted the bonnet to make sure everything was still on tight, i noticed a buubling noise near the turbos it lasted about 3 seconds then stopped then about 10 seconds later it did it again, and so on for a little while but then stopped any ideas? car seemed fine, 2nd turbo kicked in as it should and pulled like a train on ecstasy i forgot to mention the only thing thats been done to the car is new downpipe, blitz boost controller, new hoses and a paint i first thought it was in the engine but it sounds like its the turbo side just wondering if its normal because of how hot it gets also car hasnt been run for a few days Edited March 17, 2012 by ashbuster (see edit history) Quote Link to comment Share on other sites More sharing options...

Scott Posted March 17, 2012 Share Posted March 17, 2012 Are you sure its the turbos and not the charcoal canister on the passenger side? Quote Link to comment Share on other sites More sharing options...
ashbuster Posted March 17, 2012 Author Share Posted March 17, 2012 (edited) i first thought it was the engine but when i put my head near it i found its just to the left where the turbos are i painted the turbo pipes and dumpvalve and also the heatshield for the turbos all with very high temp paint for engines not cheap either its not very loud and not constant its exactly how i described Edited March 17, 2012 by ashbuster (see edit history) Quote Link to comment Share on other sites More sharing options...
welshbuddy Posted March 17, 2012 Share Posted March 17, 2012 ahh you should be ok then... But you never know, it could be the paint bubbling? just a thought .. as you did say you gave it some beans. Quote Link to comment Share on other sites More sharing options...
ashbuster Posted March 17, 2012 Author Share Posted March 17, 2012 lol no mate checked everywhere its weird should i turn my boost down anyway or would i be fine at 1.25bar i know the car it come off was a jap and run at 1.25 bar and never had problems Quote Link to comment Share on other sites More sharing options...
heckler Posted March 17, 2012 Share Posted March 17, 2012 air lock in the water feed for the turbos? Quote Link to comment Share on other sites More sharing options...
ashbuster Posted March 17, 2012 Author Share Posted March 17, 2012 (edited) im not too sure mate, i only took the 3 front pipes off that only have the blow off valve / vac pipes and the cam breather pipes going to them so i guess this isnt normal? i read somewhere a few mins ago its normal and its the just the old stuff burning off and when new fluid comes through it bubbles again but that was an american site would rather find out here from you guys lol Edited March 17, 2012 by ashbuster (see edit history) Quote Link to comment Share on other sites More sharing options...
neil tt Posted March 17, 2012 Share Posted March 17, 2012 would it be the oil as the turbos have not cooled down enough when turning the engine off, only a guess Quote Link to comment Share on other sites More sharing options...
ashbuster Posted March 17, 2012 Author Share Posted March 17, 2012 thats what i was wondering mate ive only just noticed it and maybe its just normal but never heard it before, it is quiet and i lifted the bonnet as soon as it was turned off. it could have been doing it before and its just a coincidence that i hear it after what ive done to the car lol wondered if anyone here has ever heard it do it Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted March 17, 2012 Share Posted March 17, 2012 Nucleate boiling in the turbo centre section is my guess. Google it or something. Common on turbo engines with water cooled centre sections shut down without a proper respite period of slow running. Quote Link to comment Share on other sites More sharing options...
