throttle body elbow bolt missing???

[Dr DSM]

I dont know what this is or what goes there. Its hard explain so i took some picture. you cant tell in the pictures but the threads are still good

 

[snowborder714]

Looks like it was threaded for a meth nozzle or IAT sensor.

hmmm do you think that it has anything to do with my SAFC?

 

[snowborder714]

Nope.

 

[Bud92gsx]

I doubt it....I would jb weld that up..Or get another one asap..That's a really nice looking boost leak....

Like Brian said that looks like an iat hole or meth hole..

 

[Dr DSM]

ok. anyway i can block that off?

 

[Bud92gsx]

JB Weld...Simple, easy and affordable..

 

[Dr DSM]

really? im gonna go try and find a bolt that will fit the threads. jb weld would be my last resort

 

[Bud92gsx]

If you can find a bolt that threads that might be the best looking option..Make sure to put some sealent on it to make sure it doesn't leak..

I would just go jb weld..Cause I have more jb weld then botls..

 

[2g4me]

That sir looks like the culprit of a massive boost leak...and you've found it, congrats


Seriously though, yes JB weld, or i'd personally recommend quick steel, be sure to put some one the inside too though and make it smooth and flat as possible, putting it just on the outside it may blow off under boost.

 

[Dr DSM]

Ok. The threads were partially striped so i was going to retap it but jb weld/quick steel would be a whole lot easier. Which do you prefer, jbweld or quick steel. I dont know the difference

Just put a fitting in it, that way later on if you want a boost source for a gauge or something you already have one ready to go.

 

[red92tsi]

I had a hole just like that in my elbow too, i used some high temp rtv around a bolt and has worked fine.

Since when do you use a pre-throttle body source for a boost gauge, or anything boost related?

 

[rlacasse1]

If you are using it for just a gauge then it's really not that big of an issue. Personally, I have no problem with a gauge being tapped in on the elbow.

Oh, and yeah, I suppose your wastegate isn't boost related, is it?

 

[agentorange313]

I looks like the stock 2g elbow, its thick enough where you should tap it for a fitting. It will ensure a solid fit, while the tappered thread create seal, also thread sealant should be applied as a safe measure.

The hole looks about 1/8 npt, its pretty standard size, but if it was tapped for a AIT, it might be 3/8 big, either way it doesn't appear that the hole was tapped. that sounded dirty......

A boost gauge would be doing only half it job, reading boost. What about the correct vacuum, I feel like vacuum is almost if not just as important as a wideband, its an indication of proper engine function.

as a boost source, closest possible to the source is preferred.

I agree with that.

 

[Dr DSM]

ok do you think jb weld will hold since i'm running 24 lbs of boost? should I use quick steel or rtv instead? I've never messed with any of this stuff.

 

[Boostinsideways]

Quik steel is made by the same people as jb-weld either will do fine.

Honestly I would just thread a barbed fitting in there for a boost/vac source.

Air compresses, having a boost source that far up the piping is not ideal.
Vacuum would be distorted due to the throttle plate (read my post)

Either way you are going to need to thread the hole. I would then use a mating threaded plug to seal it up. This will ensure a seal, no boost leak.

Think of RTV as a replacement for some gaskets(not suitable for headgaskets, exhaust manifold/piping). I would not use a gasket to plug a hole, so I would not use RTV to do the same. If its RTV with a combination of a plug, maybe then, just to make sure it seals.

 

[mattasi]

To fix this I personaly wouldn't use jb weld ect.. I would put a bolt that fits into it with teflon tape. If not that, then I would remove the elbow and replace it or weld it up...

 

[Dr DSM]

I already have a vac/boost gauge. im just gonna do what red92tsi said and get a bolt and use the rtv to seal it off

 

[snowborder714]

Try teflon tape before jumping to RTV. It will seal just fine and be much cleaner and easier to clean up if you ever want/need to.

 

[Dr DSM]

i just found out my buddy has a welder so im just gonna weld a small piece of metal on there

quick steel is easier to apply/mold being a solid and not liquid before it cures, and its not hard to guess amounts, i perfer it thats why i use it and you wont need rtv.
