Nas Escobar Posted April 10, 2015 Report Share Posted April 10, 2015 How bad is your original one? You might have to repair it using rubber hoses depending on the severity of the cracks. Quote Link to comment Share on other sites More sharing options...

Try looking on RockAuto.com and if you don't see it there, chances are nowhere else will have it either and you will have to repair/recreate the part.

GnatGoSplat Posted April 10, 2015 Report Share Posted April 10, 2015 I have a part # for it somewhere, or I can get it, but I'm at work now and this info is at home. Drop me a PM to remind me if you don't hear from me by tomorrow. I believe it's part of the entire vacuum harness assembly and you can't get that rubber block by itself though. Mine had some pieces worn/broken off that was causing it to leak. Tried RTV silicone, but it doesn't stick to the rubber. Ended up using black Shoe Goo to rebuild the broken parts and that worked rather well. Quote Link to comment Share on other sites More sharing options...
GnatGoSplat Posted April 11, 2015 Report Share Posted April 11, 2015 Just to verify, we're talking about that rubber distribution block that plugs into the top of the throttle body, correct? If so, it's p/n 10114903 HARNESS, EGR VLV VAC. It's the entire plastic vacuum harness assembly. The rubber block is unfortunately, not available separately. Looks like you can still buy it.
