I have an 86 L98 so this may or may not be right. That U shaped hose looks like the one that goes between the throttle body and the front of the block that carries coolant.
I have an L shaped hose that fits behind the AC compressor, goes from a hard line into the passenger side of the throttle body.
I needed one as the PO had replaced that hose with a piece of radiator hose and it was kinked and collapsing. I couldn't find one and the local NAPA store let me look through their stock and I found a hose with the required 90 degree bend in it, all i needed to do was shorted the one leg a little. Found the cutoff piece [think it's from the correct one] and still has the label on it. Napa 9801 UPC 0 29769 34286 2
I had to cut off about 2 1/2" off one leg, don't remember if I had to shorted the other leg.
If you don't find what you need, maybe you can modify or make something similar to the PCV to TPI setup like on my L98. Coming out of the pcv valve is a short length of pipe, then an elbow. After that is a length of metal pipe which runs forward to below the AC compressor. That's where that other hose I mentioned goes.
Here's a couple of shots showing how it is on mine, may be worth considering if you can't find the hose you need.
I don't check profiles - If someone's looking for parts "YEAR MATTERS and it should be mentioned. I'm frequently looking for parts (none are in my profile), there's profiles that ain't updated and on and on and on .....
What's a bit odd maybe is that, if that's a fit and correct for a '92 why won't it do a '93. The connector to the valve cover is the same and I always thought that the throttle body itself was the same '92 & '93.
it might be interesting to find a Camaro/Firebird a Buick or a Caprice '94 - '96 or even a Cadillac Fleetwood.
Actually it looks like that part # is maybe still available or on many dealers shelves.
The actual part # is 10128365 (this is not a '93 part # - this is a '92 Corvette and others)
It's as cheap as $12 on eBay but I'd shop local!! Maybe try to price match.
im confused, i really want to get it for $12. but all of the vendors say it doesnt fit my 93
I didn't say it would! I said I wonder why not & what's different. I mentioned looking at cars! Does a dealer "local" have it on the shelf? I don't know You need to ask!

the main difference between the 92 LT1 and the 93, is the valve cover itself. the 92 has the magnesium alloy, and the 93 a composite ABS "plastic" cover. the routing of the hose on the 92 comes off the top surface of the magnesium cover, where the 93 comes off the inner side of the plastic cover. different form and fit, thus the different part number.
1992 LT1 with magnesium covers -
1993 with composits ABS covers -
now, here's what I would do - for $12, i'd get the 92 hose, and try to modify it to fit the 93. i'm not familiar with the 93 - most likely it has a grommet with a 90 degree elbow fitting on the inner side of the cover. it might even be the same grommet and elbow used on the 92 - ??? i'd try cutting off the "valve cover end" of the 92 hose and fitting it to the 93 where it goes into the elbow. the OP might have to butt splice the 92's hose with a standard straight PCV hose - ??? maybe it will work, maybe not, but id give it a try. need to get creative here for a non-available part. whatever the OP does, good luck -

The connector to the valve cover I believe is the same so the modification thought is a good one. I've never owned any year LT1 and knowing the "difference" year to year is something I for sure would overlook. I know and understand now!!
Let's make sure maybe I understand. This is your second image with with '93 valve cover BUT maybe the snapshot is a '92 with the cover swap. Notice the similarity/fit of the fuel rail cover RH side.
1993 with composits ABS covers -
** I've looked at an eBay '93 offering and I believe I understand the fuel rail cover similarity. Got lucky (the first car). Third from last snapshot offered:
The other difference I noticed is the '92 is hose from throttle body to valve and the '93 I believe is a "hard pipe" with flexible push-ons to likely the valve and the throttle body. Look closely to "JoeC" snapshots and "ZOOM" the image in the eBay offering.
The F-body and B-body cars never got the composite covers so that would validate the valve & hose combination fitting likely.

- good detail call. it would be nice if the OP (or anyone) posted a pic of the RH side of his 93 LT1 without the fuel rail cover. I sure would like to see how it's configured. if it's mostly metal tubing, the fix should be simple -
note the angled valve cover grommet in the above pic...
looks like the 93 LT1 configuration is mostly (ABS) plastic tubing. doesn't look like there should be an issue here, unless the plastic tubing IS the issue - ???
found a pic of GM# 10186200 - 93-96 corvette LT1 PCV hose assembly -
i'm not understanding the OP's original statement -
My hose that goes from my pcv valve to throttle body is cracked badly
is there an ACTUAL pcv valve here, or is it just an elbow going into the grommet, and what's cracked? my understanding is the PCV valve is on the LH side of the engine, and connects to the plenum via that "U" shaped hose.
Could someone tell me the other part that goes inside the semicircular hose that the PCV valve fits in on the 94 Corvette. PCV valve goes in the left, but what is the part inside the right side of the semi-circular tube.
I thought the 92 elbow (at the valve cover end) could also be put in the 93 and up valve cover. If so then you could just cut the elbow off the 92 hose and use it.
I'll measure the diameter of the elbow when I get home and post it.
The elbow on a 92 is 3/4 in where it goes in the valve cover 1/2 in where it goes into the hose

PCV Hose to throttle body part #?
