bloody turbo started ticking noise

[dean3982]

after fixing the previous turbo problems the van ran sweet. today while driving home the bloody thing has started making a strange ticking noise!!! it was running and then when the turbo actuated, it was whistling like a brand new van and felt amazing considering that i fixed it myself. now when it actuates, i still get the whistle but with a slight ticking noise behind the whistle.... ANY IDEAS PLEASE??????

Vane creep ?

what is vane creep???

Slight blow from a joint, check nothing has backed off now it has had a few heat cycles.

well i fitted the turbo to the van back in early january and a new intercooler and pipes! so ur saying that it may be as simple as checking over fitting as i have covered about 1500-2000 miles since fitting. there is no loss of power at all just a little reluctant to put foot down as i cant afford to be without a van for weeks again!!!

In my Caterham, this approach has solved approx 100% of issues!

And it's free

when you say blow from a joint, do youmean joint between turbo and block or turbo to intercooler pipes or somewhere else because the ticking noise sounds like when you hold a lollipop stick on bycicle spokes almost but almost silent??? really confused now!!! :/

Around exhaust manifold to turbo kind of area

Tick will be exhaust manifold to head joint/ manifold to turbo joint or turbo to downpipe joint I imagine, inlet side would hiss not tick.
