c7 breather tube?

[donnyjay]

Looking for the cat replacement slobber tube. Two dealers don't have a listing. Prefer the cat part as I already have a homemade tube sticking out the back. Found a part number 269-2002, but the parts guy said its not a good number.
Any suggestions?

The Cat part number is 288510. This is what I purchased for my 2005 C7 Cat. Make sure to stay with 1" all the way out, so as not to create excess back pressure

Correction Part number is 228 8510
Sorry

You don't need a 1" the stock one is not that big. Joe

Has anyone thought about running the slobber tube over to the exhaust pipe and drilling into the pipe and making a venturie scavenger. It would accomplish two things. It would help draw out the blow by and the heat of the exhaust would cook off the mist.

Wouldn't the venturie scavenger effect create a vacume on the slobber tube?
That might have a negative effect by drawing more oil residue than is normally created by the engine. I originally extended my slobber tube to exit just below the exhaust tip thinking the exhaust pressure would blow the oil mist to the ground. Unfortunately I still had oil scattered onto my TOAD. I modified the slobber tube extension and routed it into the "peanut butter jar" and had excellent results.....no more oil on the TOAD and rear of my MH.

I also have the peanut jar and it also works great. I was just a sittin' and a thinkin' which was probably a bad thing to do. The venturi effect is probably a bad idea due to what you mentioned. The other thought I had was to stick the slobber tube into the exhaust pipe just after the muffler in hopes that the heat of the exhaust would cook off the mist. Or do you think I should stop thinking and go outside and get my chores done ??

I'm and old Navy Man and I recall having to pump the bilges and voids of water on the light cruiser I served on. We used scavenger pumps which were nothing more than venturie aspirators, which used a high pressure water stream to draw up water and eject it overboard. I'm not sure if the same effect would be caused on the slobber tube if connected in line on the exhaust. Until someone actually does as you have suggested we'll never know. Your idea surely has merit. If the pressure from the slobber tube is greater that that of the exhaust I doubt there would be a problem! In that case you would be injecting the slobber tube discharge into the exhaust rather than vacuuming it in.

And my hope would be that the heat of the exhaust, after the muffler, would be sufficient enough to turn the mist into dust. My exhaust pipe is 5 inches in diameter and 4 feet long with zero back pressure. I just might give it a try.

Donny:

If your C7 is installed in a Freightliner Chassis visit your local FL dealer and have your VIN/FIN with you. They will have info on the exact slobber tube installed on your Cat. If they don't have it in stock they will order you the correct one.

If you haven't done it the first thing to do if you are getting oil out of the slobber tube is calibrate your dipstick. The dipstick and dipstick tube in the Cat engines are not supplied by Cat. My Freightliner XC-R C-7 engine dipstick was calling for 5 quarts too much oil to reach the full mark. I have the shallow pan and the correct oil amount including the filter is 19 quarts. There is a high likelyhood your dipstick is wrong if you are getting oil out of the slobber tube.

I found the canister assembly and ordered it from the local CAT dealer. Will install it and keep you posted. Cost $358.00.

I put the freightliner One on our coach , at an outing I was parked up against a bank (sand) it blocked the tube Blow the turbo and some other things (none of which were good, and all very expensive) I made one out of Electrical conduit. With a rubber downturned hose on the end, That will slip off, and help keep the mist down. IT ends beside it hitch. All is good. No cansiters,, No peanut butter jars;;
