Nice job on the fix. Glad it wasn't anything more.

Where did you get the tiny c-clip from?

hehe, It's the one that holds the actuator arm on. I'll have to stop this afternoon and get another one. They sell them in most hardware stores.

lol that's what I was thinking. I'm also thinking we have a very similar turbo. It looks almost identical to mine and is having the same wga flapper issue.

I was going to suggest checking that, but it seems you already found it. I fixed mine by just removing some material from the inside of the housing around the wastegate flapper. That worked for a while, but then I had the wastegate puck replaced with a larger one after a wastegate port, and welded it in place. I hope that clip holds up though. I would be unsure about it holding up for very long.

Uhm I think my Garret has a loose flapper door, dont they all?
Its just that Chine copied that but didnt create enough clearance.

my 2560r has a loose flapper, if my dp isnt JUST RIGHT on the hot side of the turbo, the flapper sometimes gets caught on my wastegate tube. Might wanna take a small dremel tool to it just to make enough clearance.

The flappers are loose to give the seating some tolerance so it will seal. I think the chinacharge might have excessive tolerance. But you don't want it tight to the point that actuator spring can't make it seat flat against the turbine face.

I did a mild, lethargic search to see if you had posted a driving review of this turbo but didn't find anything.

Since you ran it back to back with a genuine 2560 what do you have to say about the China 2870?

Full report please and thank you.


**** EDIT***

I just saw the YouTube vid. where it was making some scraping noises, that probalby answers it right there........

Nice vid... mine is hitting the downpipe on opening right now...

I'll have to look for this problem too once the downpipe is off, much appreciated!

I'm having the exact same issue. the turbo seems to shut the door fine on it's own, but if I unhook the WG arm, I can bind it in two spots. Now I know what to look for..

Got my issue fixed... wastegate no longer hits downpipe when opening...

Had to take off downpipe and enlarge the opening to the wastegate tube. Also bored 5 bolt flange to make it oval for finer adjustments when re-installing.

Another issue was the the wastegate arm was moving up and down with WAY too much play when it is heated. Put a tack weld on the washer so it no longer moves.

Boost Creep issue FIXED.

Yeah my issue is jamming of the WG only when it closes and some minor creep. Gotta fix this before I get a dyno done..

Confirmed, same exact issue as OP, except I had secondary minor jamming on the FM elbow. I grinded the elbow down some and put a clip on the inside of the WG, should suffice I imagine.

Hmm, first I've seen of any chinacharger defect! Good thing it wasn't anything major...

p.s. I wonder if theres a fix for it BEFORE it breaks, for all those running china's out there

Der_Idiot

iTrader: (2)

It's not a break or wearing out, it's like this from the factory. A C-clip the same size as the one on the wastegate is of sufficient size to hold the flapper door in place and not take all the play out of it.

C-Clip fell off, binding again. Debating going EWG, but drilling the FM manifold is kinda.. hmm.
