Default Throttle Body vaccuum lines

So I was cleaning my throttle body (it didn't have carbon build up, it was almost literally sludge), and to my pleasure, the vaccuum lines literally fell apart in my hands.

Is this something I can replace with standard tools, or am I going to need to lift the engine out? If I can do it at home without a hoist or anything, what sort of tool do I need to reapply the vaccuum after I put in the tubes?

And for that matter, what's the part number for those tubes?

Try getting the lines at a salvage yard, no need to pull engine to replace those. If you were to buy from a dealer, I believe they come as an assembly.

As for the sludge issue, check you PCV valve by taking it out and seeing what brand it is and if it rattles. Aftermarket PCV's are known to let lots of oil by and that will sludge your TB/intake area pretty quick. Also, if the spring has become stuck with sludge it will continue to let lots of oil by, a shot of carb. or brake cleaner should free it up.

The car has about 267K miles on it & I don't think it's ever been cleaned, and has needed very little replacement, so it wasn't an issue, just basic maintenance I was doing since it's such a high mileage vehicle.

But I'll check around & see what I can find.

So does anyone have a part number for them? I can't seem to find it anywhere.

i've got 21015141 and 21007268 as P/N for vent hoses, but maybe you mean something else.

isnt there only one vac line off the tb in 3rd gens? its the one that goes to the evap purge solenoid (irrc, or is it fuel pressure regulator?). if you still have the part that clips onto the tb you can just replace the broken parts with rubber vac line tubing from your local hardware store.

That's my temporary fix for the moment. I just gotta wait 10 days for the parts to get shipped to my service center.

Rubber hosing is holding together right now.

you want to see the vac setup on my saturn? Rubber hoses are not a temp fix, they're a permanent solution.







and thats how they are right now and they're staying that way. Of course thats with the geo throttle body and its on a 1st gen so I have 3 vac lines.

Just walk into the autoparts store. They sell them by the foot. The PCV has some elbows that will be on a rack with misc PCV items. I recommend using real hose clamps on the lines, rather than just shoving them in.

I'm interested in a catch jar, but I can't find any good tutorials on how to make one. I'd rather not buy one though. I'm a part-time tinkerer, so I'd rather do it myself.

If anyone has a good tutorial (preferably with pictures), let me know.
