Slobber tube - cheap fix for blowby
Hi Greg,
I placed the sump directly under the tubes' original placement. I just snipped off the bottom 6" and connected the tubes to barbed nipples that screw into the PVC sump and they seem to dump a good amount (1-2 qts) of sludge into the sump between oil changes. At most, they are 15 degrees off vertical and do not seem to have a problem draining. I did the modification when I bought the coach 3 yrs ago and have run this way for about 30K miles with no leaks elsewhere. The key is to keep the breather element on the sump clean with a shot of brakekleen now and then.
