Slobber Tube Fixed The Right Way!

[bumpersbird]

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!

Who are you and where are you located? I have a '95 PT42 and would
like to have more information on your issues.

Bumpersbird,

Please do keep us posted. 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>).

Kurt, you have written some good information here. But to the life of me, I
can't figure out what bird you have. maybe I missed that somewhere???

I got my Racor CCV6000 with the hose kit from Shurst Corp. 4Wright
St. New Bedford Mass. 02740 508-999-3261. 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!

Sincerely,

Kurt Horvath

Tom,

I am Kurt Horvath; I live in south central Tennessee

There isn't enough space in cyber space for my issues !!!!!!!!
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

Kurt,

I'd love to see the photos ... you can send 'em to me at
aeonix1@... or post 'em somewhere where I can download them.

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.
