Throttle Body Cracked

[pkniland]

I was removing the throttle body to clean it and I found it was cracked where the throttle cable bracket attaches.

Outside of a used throttle body are there any other options. I doubt something like this could be repaired, but I figured I would check.

That's not just a casting line from when it was made?

I doesnt look like that and I haven't seen anything similar on any pictures but it could be. Anybody have any insight on this?

Casting mark? Spray carb cleaner on one side and see if comes through to the other?

Based on what I see, it's not a casting line.

However, since it is aluminum, you should be able to take it to a weld shop that does AL and they should be able to TIG it. It will have to be cleaned VERY well with carb cleaner and brake cleaner to remove all residue inside the crack or it will contaminate the weld and it won't work.

Otherwise go to @arcteryx (Jason at Cruiser Yard) for used parts.

Not necessarily the correct term but the lines left behind after being in a mold or whatever. Like the other lines on the outside of that same piece in pic #1 & 2 of the OP. The 2nd group of pic's does look like it's torn, though.

This is why you shouldn't do maintenance! You find things and freak out about them. Was it running poorly before? Probably not. Now in your mind you think it is going to blow up!

But seriously, it sure looks like it's just marks from the mold or whatever. Do what @Tools R Us says.

It was running poorly, but I don't think it was the TB. I think it's a combination of the charcoal canister being clog, the HG leaking, the tear in the intake hose, and a few random vacuum hoses that weren't connected to anything (Ive only had the truck for a couple weeks).I think im going to go the welding route if its reasonable, if not Ill probably just throw it back on as is.

I wouldn't throw it on as it is because when (not IF, but WHEN) it breaks off, you will lose the throttle completely and you will come to a stop, wherever you are, with no allowance for a back-up way out of the situation.

Fix it or replace it while you have it off.

Nothing a little bubble gum or quick steel won't fix, duct tape would work too.

I was thinking to hit it with a torch to melt it back together... I'm sure this isn't recommended for some reason...

if it's really a crack (looks like it), nothing that somebody with an Alum-capable welder and some skills should not be able to fix in 10 mins if you prep it all, I would think.

Did you get it fixed?

This is somewhat near my professional expertise. Long story short, Marine Corps trained sheet metal mechanic, been in aviation for 10+ years, and now a sheet metal quality control inspector. What it looks like to me is that there was a crack, gouge, hole, or some other defect that someone apparently cut out and attempted to "fill" the hole with another piece of metal cut to size and used an adhesive to bond the two pieces of metal together. This is half of a standard aviation sheet metal repair; the other half of the repair would be to rivet a larger piece over the cut out and filled area. If this is the case, I would be inclined to repair the throttle body properly because that piece is destined to come loose at some point. Just my two cents.
