Can anyone identify this part??

We removed it from the truck, specifically the front driver's side corner of the intake manifold, over a year and a half ago and now have no idea what it was for. Any ideas??



EDIT! This was not removed from front driver's side corner of intake. It appeared that way in a photo but upon closer examination, this is incorrect. We're back to square 1 on this one. I have no idea

Maybe a lifting eye?

Re: Can anyone identify this part??

It seems to have a bevel to the hole in the center which indicates it had a real purpose. The motor already had 2 lifting brackets besides this one so I doubt that's all it was used for but ya never know lol

Re: Can anyone identify this part??

I have a similar one at the left rear of my intake, but it has a square hole in it to run the kick down cable through.

Talking Re: Can anyone identify this part??

Might be to route a power brake or PCV hose through? It appears to have a hole for an accelerator spring.

That's my guess anyway.

What does the winner get?

X2 Exactly what I thought too. My '72 K5 Blazer had one of those on the driver's rear of the engine where the vacuum booster hose passed through.

Re: Can anyone identify this part??

Bob, the accelerator spring part makes sense but I'm trying to determine what the large tapered hole is for. For the life of me I can't remember what it was used for and it looks kinda important and I'd like to reinstall it if I could

Anyone have a pic of this part installed so I can use it to compare notes??

Re: Can anyone identify this part??

Did your truck have cruise control? Or, the factory cable to keep the engine from shifting to one side on acceleration, but i think that was on the passenger side...

Re: Can anyone identify this part??

I also believe it's for the vacuum line to the brake booster

Re: Can anyone identify this part??

I have a bracket on ebay from an Impala. You'll notice the hole is the same. It had the power brake hose going through it. See it here:

http://www.ebay.com/itm/71-72-73-74-...item231f83065b

Sometimes they have a rubber grommet in that hole too.

Re: Can anyone identify this part??

. . . .

In the center of the first picture below, there's a bare metal part with a rubber grommet inside of the hole. This was said to be from a 72 with 10,000 miles.

In the upper right corner of the second picture, from a 70 GMC, you can see a bare metal ring with a hose going through it.

Could it be one of these ?

Re: Can anyone identify this part??

Steve, it looks like your second pic is spot on as it came from a 70 GMC. Apparently it is for the brake booster hose.
Thanks everyone for another session of knowledge. I suppose I should blast and paint this part for when the booster gets reinstalled huh?

Tony

Re: Can anyone identify this part??

. . . .

Here's the entire picture . . . it was from an original, low mileage 4X4 Suburban.

Maybe you can blast it and just spray clear coat on it, since it looks like it was bare metal when installed at the factory.

When you put the black hose through, it will stand out as a rare part, most engines don't have !!!

Re: Can anyone identify this part??

It is for the brake booster hose. It keeps it away from the throttle linkage, so it won't interfere with it.

Thanks fellas. It'll be getting the media blast and paint treatment before reinstallation
