I'm new to this site and when I saw the yellow gunk in my new '03 I got a little worried thinking it had blown a head gasket or something. But by the pattern left by the goo I could tell it was not originating from below in the oil supply. Until today I'd never heard of this issue so pardon my ignorance on the topic. Some said it won't hurt anything but I can't help but think there might be some long-term negatives by having water/oil slowly oozing into your oil pan through the fill tube. Has the baffle fix mentioned by Y2kota worked?
WARNING LOTS OF :blahblah: AHEAD :sorry: BUT IT HAD TO BE SAID.
It helps. That "water/oil slowly oozing into your oil pan", that's where it comes from. Its blow by gases from the cylinders. Follow the hose coming out of the right side of the oil fill tube. That goes to the back side of the in-take manifold. The in-take manifold causes the gases from inside the block to be drawn up through the oil fill tube then into the in-take to be burned off. When the gases pass over the cold oil fill tube, the moisture collects and builds up the "sludge" you see. The colder the air passing around the outside of the OFT (oil fill tube) more of the sludge will accumulate. Warmer weather will dissolve the sludge.
The baffle creates a smaller area that the sludge will build up in. Also take it out of sight of the consumer. Pull the baffle out and you still see the sludge.
OFT - insulated Basically what I have done to my OFT is to insulate it to help the warm gases from the block melt off the sludge. It works some what.
Ele. Fan install One small benefit of installing the Viper Fan has helped to a small degree here also. In the colder weather, the stock clutch fan is constantly blowing cold air over the OFT at all times. This just causes more sludge to build up. Also makes it harder for in the gases to warm the sludge and melt its self off.
Short drives, not allowing the engine to fully warm up and melt off the sludge from the is cold is a big cause of this.
Hope this helped :banana2:
