Slobber Tube Fixed The Right Way! - bumpersbird - 08-01-2007 13:40 After a lot of research & web surfing. I found two alternatives for the slobber tube on our coaches. When I bought my coach I had overheating problems. 95 WBWL 42' with the Detroit Series 60. The radiator was so packed with oil and dirt it looked as if it had been stucco'd it was 80% covered, not a good thing! After a wash out it cooled better. But it didn't fix the cause. Oil vapor from the slobber tube. Vapor is vented from the top of the valve cover on the Series 60. I believe the 8V92 and 6V92 also have 2 vents on top of the motor. The fix is called CCV (closed crankcase ventilation). Two companies make these filters. Walker Airsep & Racor. After my journey through cyberspace I found several websites that deal with diesels in large pleasure boats.http://www.deiselboat.com I think it was where the best info came from. These guys are running two motors up to 16V92's in enclosed compartments. Anyway long story short. Most of these guys have chosen the Racor CCV6000 series. Several switched from the Walker to the Racor that is why I choose the Racor. Not to mention it was half the price. I paid about $370.00 for the filter and the hoses. The system from Racor has more features,(Saftey Features, it will not let the internal pressure of the engine go beyond specs), and they are a large company with lots of tech. experience. The system works like this. A hose is connected to the vent on top of the motor, it leads to a filter that separates the coalesced oil vapor, the oil is returned to the crankcase and the remaining volatile vapor is routed back into the intake system to be burnt in the engine. Clean, fuel efficient. Simple! All new diesels have these systems '07 EPA and all that stuff. Anyway I'll let everyone know how it works out this week going on a 1500 mile drive. If it works as advertise no more oily film on anything! Service life of filter is up to 750 engine hours. New filters are about $35.00. Open the filter drop it down drop in new filter element, close the 4 clips and away you go. A far supior fix than any catch can!

I, too, had a similar experience -- but I replaced the radiator core with a newer, more efficient design. Cooling is much better... but, as you say, the source of the problem remains. Where did you get the Racor system? Did you install it yourself and, if so, how difficult is the installation? Thanks -- this may just be the solution I'm looking for. (Of course, it means yet another filter to carry along....<sigh>). Pete Masterson '95 Blue Bird Wanderlodge WBDA 42 El Sobrante CA aeonix1@...

It was about $380.00 with shipping more or less. All the other sources I checked wanted a few hundred more! Shurst sells a lot of Marine products I found them on e-bay, their selling name is 4land4sea and they have 100% feedback. I did install it myself, very easy, well not really. The major problem was where to mount it. It can be mounted directly to the engine but, you'll never find a place there. It is an indication as to how tough this filter really is. I built a bracket from 1/4" aluminum L stock 24"long, got it at Tractor Supply (TSC). I mounted it on the bottom of the bracket that holds up the air intake pipe on the forward firewall. Just take off the bolts, use the bottom part of the clamp as a guide to drill holes on the L stock, make sure that the flat side of the L is facing you, out to the roadside, put the clamp back together, the L bracket goes under the bracket that holds up the air intake pipe, I used a couple of washers tighten up the bolts and your done. Of course you'll want to mount the filter on the other end before you bolt her in. It holds the filter parallel to the engine. It's quit ridged and I expect no problems from it. The hard part was welding the 1 1/4" nipple that is needed to suck the crankcase vapors through the filter. Mine is located about 45 degrees down and 3 inches or so back from the bracket that holds up the intake pipe, racor sells a sleeve with this nipple on it but it's really more of a marine application. If you do it the way I did it make for clean straight shot into the intake pipe. Of course you have to take off the air filter and the intake pipe to get in there to work on it. If you like I could send photos, you know each photo is worth 1000 words, and after rereading this post you'll probably want them. It really wasn't hard and I'd be glad to walk you thru it. One problem is the old slobber tube. I can't get it out of the coach. Next week I'm going to Prevost in Nashville and I'm sure they will get it out one way or the other, but for now I've some plastic ties holding her in there. P.S. Pete I've read a lot of your posts and we do have similar problems. I have most of mine fixed after 1 year. Too many I think. I've spent a lot of time $'s but, I love my BIRD! At 750 hours Op time I wouldn't carry an extra filter. By the way where did you get radiator and how much was it. BB doesn't have them anymore!

I'd be happy to compare notes; I've spent way too much time and money on my toy! By the way we named her, "Indulgence", I have had overheating problems, a new camshaft, she ran great on 5 cylinders got better mileage than I get now as strange as that sounds. And so many other things if I didn't love her I'd have shot her by now. Tranny output shaft seals, a complete front end rebuild, everything except the kingpins, probably should have done them to. Water leaks, A/C leaks, Fridge ice maker leaks. Toilet flapper out of control. 50 amp. switch for genny and land line burn up the morning we were going to FLA for X=Mass. Alternator I could keep going but, it's redundant. Oh yes my favorite was B.B.'s idea on how to wire up the plug for a trailer! Send me a note if I haven't worked on it yet, I will shortly. I have no illusions, she is a demanding mistress. Kurt --- In WanderlodgeForum@yahoogroups.com, "Tom McCarthy" > > Who are you and where are you located?

You say "weld" in your description. That worries me a bit as I have no experience as a welder nor do I have any welding equipment. As for the radiator core, someone on this list had suggested a core vendor as being "good". I called them and they gave me referrals to several radiator shops in northern California. (I'm afraid that I no longer have the vendor's name.) One of those referrals had an ad in my local yellow pages with a claim that they did "heavy equipment." After calling and discussing my situation with the owner, I discovered that he had a contract with one of our local transit districts to do the radiator work on transit busses. He showed me a core made for the transit bus that had round tubes in a staggered pattern through the core rather than the oblong, semi-rectangular tubes in the standard BB core. He claimed that the "new" design was more efficient at cooling. He ordered it from the vendor whose name I can no longer remember. I was invited to come every day to the shop and view the work that was being done -- which I did. The radiator shop owner was an avid RVer, so he even had a 50 amp circuit available to plug in the coach while his shop was working on it -- in addition, he had a 24 hour watchman that lived (in a trailer) at the back of the property. The bill came to about $4000 -- but that included about $1000 work on the AC system as well as changing out the radiator core. The core itself was $800 or so (with exchange). Most of the expense was the labor required to get the old radiator out and then put the new radiator back in place. Labor rates are typical for the San Francisco Bay Area (not cheap). In the (nearly) a year since I had the radiator work done, I haven't had an overheating incident -- indeed, the water temp rarely goes above about 180-190. I was thinking about adding a watering system (as discussed on this list a few weeks ago), but am less likely to now. The only heating concern I now have is the oil temp seems to run up to the maximum of the 'safe' range on some steep grades (especially on a warm afternoon), but the water temperature is still in the middle of the safe range. This is more of a personal 'heart burn' problem in that the engine doesn't actually seem to be overheated, but it sure makes me nervous.
