I have a GT3255E with a WadeFab topmount manifold, and I bolted the turbo and WG to it last night and noticed that one corner of the turbo is not completely flush (kind of worn/grinded down in the corner closest to the camera):



It's completely bolted down at all four corners with lock-washers and nuts (err, it will be when I get the rest of the nuts from the hardware store today). Will there be a leak at this corner?

No kitchen counters were harmed in the taking of this picture.

 

Was the T3 flange on the collector resurfaced after welding?

Well I didn't weld the manifold, but it's not the collector flange that's not flush - it's the turbo exhaust housing.

 

It doesnt look that bad from the pics. Your gasket will seal it. Don't worry about it.

 

If there is a leak, a gasket is not going to fix it. You don't even need a gasket when bolting the turbo to the manifold. It hard to tell from your pic. Can you get a close up?

 

try resurfacing the turbo flange, check to make sure its all flush and level, the re-bolt it back up with a new gasket, should seal good then.

You checked both with a straight edge and determined the exhaust housing is warped and it's not the flange on the collector that's warped?

I didn't check anything with a straight edge. It's a brand new BMC flange and Garrett GT3255E exhaust housing. I made this thread because I noticed one of the corners (pictured) is slightly worn down in the corner and I'm wondering if a small corner that's rounded out would affect the m4d h0t exhaust action going on in the middle.

Try to get a closer picture of the turbo bolted to the manifold. You could also get a leveler and show a pic of it on the exhaust housing and another one of the t3 flange off the manifold. Then maybe tony can better suggest what to do.

 

shine light through the housing in a dark room and see if it makes it through

 

Flanges warp when welding, they should always be resurfaced after welding. If the flange was not resurfaced, that's your problem. The housings don't warp, the flanges that are welded to do.

Well I assume the person that made the manifold re-surfaced it before shipping it out to me. I'm not trying to create problems with the maker of the manifold, I'm focusing on the fact that a corner of my turbo is missing.

I'll take more pics later.

 

I can see where Tony's going with this, but from the looks of it (and from what you're saying) it's the corner after the bolt hole that's grinded down. As long as the inner surface isn't messed up I don't see a problem.

Well, never assume that these manifold makers take all the proper steps, most i've seen don't bother to resurface flanges after welding.

Either way, now that i re read it, i see that you're asking if it will leak, not complaining about it leaking. If it does leak, resurface the flange. Asking us if it will or not isn't going to get you anywhere, none of us can tell you. If you want to check it, measure both surfaces with a straight edge.

 

use some honda bond roffels

 

if you have feeler gauges, stick one in it and take a pic... may that make a better visual for people to see?

 

You realy need to unbolt the turbo and get us some pics of the flange on the collector and the inlet on the turbo , they way it sounds the collector flange is warped and need to be surfaced .

i used feeler gauges once.. to check my valve lash, and my motor was like Tee Hee that tickles.. LOL

Everyone keeps talking about the manifold...I MADE THIS THREAD BECAUSE A CORNER OF THE TURBO IS WORN DOWN, AND I'M WONDERING IF IT'S GOING TO LEAK OR NOT.

Guess I'll find out on my own when I get my car running.

that size flange is that? T3 ??

use one of those metal gaskets from ATP turbo... that would probably help

 

Get a better picture of the "gap" buddy!

 

I have seen this with a couple Precision/Garrett turbochargers. None of the turbochargers leaked. Your's could but I doubt it. Good luck

Yes it is, and I am using an ATP metal gasket that you can see in there.

ohh ok i cant really see it, but if its there i wouldnt worry about it.. im sure it will seal fine
