Is this black part (the part the actuator is attatched to) on my manifold supposed to move or swing? It looks like it should. I physically can't move it with my hand. Does it need pressure to move?






Thanks

 

yes, internal wastegate. have you run it this way?

 

It's a very long story, but it used to boost 6psi, then after I got my lower IC pipe, and downpipe redone I hit over a bar and blew the motor. I saw the guy using a vice grip on the actuator, so I get the feeling he broke the wastegate, then I noticed that thing isn't moving. Should I be able to move it by hand?

EDIT: also, is the actuator supposed to move? If I take it off of that mount, I don't think it really moves much...

 

You should be able to move the flapper valve by hand.

You should not be able to move the WG actuator by hand.

 

on me! Let me try moving it without the actuator attatched to it

 

Still doesn't budge

I COULD try hitting it with something, but I don't want to break it

 

From the picture it looks like the dumptube from the wastegate flap is too small. Try taking your downpipe off and move the flapper.

 

the black piece you are talking about goes to the inside of the turbo,its the flapper for the internal wastegate,with the actuator disconnected,it should flap around by just thumping it back and forth with no effort at all.if it does not,then pull your downpipe off and look for a quarter sized flapper,see what the hold up is.you can move the actuator by hand but it should be pretty hard,not easy at all.you van also blow in the line,or hook a compressor up to it(using about 12 psi) to make it move.if it does not move than something is screwed.if he used something to pry the actautor arm off ,he could have bent the internal wastegate arm.

 

Thanks a lot guys

I'll try hooking up an air compressor to it and see what happens. If not, i'll pull the downpipe.

 

is that little tiny tube coming off the flange for the wastegate? I would guess that something in there is hitting and not letting it move..

I would not hook the air compressor to it. 50psi will likely blow the diapram from teh actuator.

the guy was probably using the vise grips to hook the actuator rod up.. That is pretty standard since you have to pull very hard to move it.

 

Are you sure the DP flange isn't holding the flapper shut?

 

You mean when they redid my downpipe? How would I check for this?

 

oh,they redid your downpipe,thats probably the culprit then,pull the downpipe off,and take a look to make sure the flapper moves.the dp might be keeping it from opening up all the way.

In that pic, it kinda looks like the DP flange might be blocking the flapper so it can't open. Take the DP off and see if the flange interferes with the flapper's movement.

 

If they put that flange on and it is blocking the flapper then for the first time since the vise grip story I am fully supporting you and they need to give you some money for this.

Thank you sir

This could explain why my car used to boost a steady 6psi and then boosted over 1 BAR right after I got it back from that shop. If something is blocking it from the inside, it's clear that all this is their fault, and they'll be hearing from me soon

I'm gonna pull the DP off tomorrow and see what's goin on in there.

Thanks for all the help!

 

HAHA!! Its the downpipe flange. The dumbass that made it didn't leave enough room for the flap to open up all the way.... The Greddy extension that comes off the turbo is deeper and allows this to move. I would deff make them pay for that one. What a boneheaded move.......

Will this be hard to fix? Will I need a shop to fix this? This sucks, everyone recommended this shop too!

 

What kind of turbo is it? If you can find the original O2 housing that it came with, that would solve your problem, assuming the O2 housing outlet points the right way.

 

Pull the pipe off and see if they ported the dumptube so there would be room. Even if he did, it looks like if the flap opens the damn thing will still clog the dumptube and overboost anyway... terrible design all around... You'll prolly need to have one made without using a dumptube.

Rob

 

What concerns me is that they didn't do anything before this weld. They used what I had before, and added to it. Please excuse the mess, I'm rebuilding the block

 

holy crap. people recomended that shop to you? how much did you pay? I can hoestly say that is the worst job I have ever sceen. To do the job right they need to cut a pipe in half then use the half round to merge into the main down pipe.. the area between the two on the inside needs to be open. That probably doesn't make sense.. Have you ever sceen a dsm o2 housing eliminator? like that..

 

I have never seen one. Does the pipe need to be extended where they welded? What exactly is a 'half round' Sorry i'm

 

BOO on right angle bends!!!
