Throttle Plate Damaged

[[ion] C2]

It's been sticking between 1-15% lately (lately as in past year).. and I kept trying to adjust its position so it doesn't contact the edges of the bore, but since then, it just got worse and now it apparently wore down the top edge of the blade so air goes by that shouldn't, causing me to have a nice vacuum leak and an IAC valve that is fully closed and ineffective at idle.

I have spare throttle bodies but 52mm stock ones. My throttle body is a 62mm RSM one.. I have a post on my local forum seeing if anyone knows a place that can fix it, otherwise, does anyone know of a place I could send it to for repair?

[a.graham52]

cant find a nother throttlebody and just swap out the blade?

[[ion] C2]

TB is bigger than stock.. none to pull it from

also, it's been sticky and I want it to be repaired right

[sleepyalero]

could a machine shop do it?

[jawa]

or you could get a TB off the intregue 3.5 twin cam

or you could get a TB off the intregue 3.5 twin cam

he has a 2.4

[[ion] C2]

he has a 2.4
unless the 3.5's TB is a 62mm stock

[Mike The Canadian]

Unfortunately it's 65 mm

this guy bores jeep TBs to 62mm and installs blades. maybe you could contact him and see if he has any blades you could modify

[falloutboy]

what about the company that sold your TB? Either they have new blades (and screws) or you could ask for an exchange or repair.

Then on the other hand, a good machine shop a pile of dough and time should get you what you need

[[ion] C2]

It's RSM, they're gone. I wouldn't trust them to do it even if they were still around.

[Oldsman]

Have a machine shop make you a new one. They are easy to make.

[falloutboy]

outsch :(
ok. Well they probably just copied an existing TB - just have to find the original one at RockAuto :)

[AleroB888]

Probably time for a new TB -- bearings worn out, excessive sideways movement in shaft area, etc.

Yeah, they took a 52mm and bored it out and made a custom 62mm plate for it...

Maybe it's time to upgrade to LS1 75mm?

[sleepyalero]

might as well....

[jawa]

question is what caused it

[a.graham52]

i was looking at 2011 equinox today, had the intake off, i noticed the throttebody on that thing was quite large even with the ecotech. maybe look into the size of that thing?

[[ion] C2]

Kinsler (local) can make me a throttle plate real quick and cheap. Forgot that they do that sort of thing.

I also came across this old thread about my 62mm TPS problems, and noticed the reason my plate can move up and down so easily, that metal ring that's supposed to restrict vertical movement is messed up.

[unchained01]

Get a hold of Marc at TCE (british car conversions ) he should be able to get ya one pretty quickly. Either the plate or a new TB.

[[ion] C2]

Kinsler's very local, they're gonna make me a plate and fix my alignment issue.

[jawa]

so what caused the damage

[[ion] C2]

Shaft movement, I showed it to them today. Throttle plate can be moved up and down like crazy when it turns. There should be something to prevent such movement. Unfortunately they're really busy and it will cost some time to even see if they can fix it. The plate will probably have to be custom cut, depending on the bolt spacing.

One suggestion was to upgrade to the 75mm LS1 throttle body since that would be probably cheaper (I dunno what they go for though).

I know where you could find one of those!! :lol: :lol:

[falloutboy]

off to RockAuto he goes :)

[jawa]

65 mm is stock on the twincam v6

[[ion] C2]

throttle body itself has a problem allowing shaft play (i think that metal ring as seen in my j-body post from 2008) so it won't be as simple as just replacing the plate (assuming it's got the right bolt spacing and diameter I need to fit without issue)

so i'll probably just switch to the 75mm LS1 one since they can be had for cheap. the only thing i need to find out is how to connect my throttle cable to it

[zearchyo]

so what happen with this thread

[[ion] C2]

I bought a stock one from a junkyard yesterday because both of my spare ones are gone. I put it on but the car doesn't stay running, lol. I forgot to bring my laptop to my parents' house where I installed the TB.

So today I'm bringing my laptop and I have to edit the tune a bit for the smaller throttle body, and it should be good. I just need something to work temporarily.

Going to buy an LS1 throttle body off a member on LS1Tech and then weld a new flange to my intake manifold and use that soon.


Look at that gap on the 62mm TB. I could fix the shaft play problem pretty easily, but getting a new plate is the only trouble. Anyone want it?
