86 PT38...any pitfalls?

[Curt Sprenger]

Scott,
I sent to you two PDFs on the Series 92 engine. You can locate "slobber
tubes" and a whole lot more. Enjoy.

To slobber and breath are very different. slobbering is a necessary
act for the 2 stroke V92's. The dripping oil is from the scavangers
((I will find a previous post) some models were routed to drop the
oil into the crank case. There is a DD mod to add tubes for those
V92 engines without slobbertubes. The crank case vent tubes on 4
strokes wont spit if you let the engine get warm and keep it at the
engineered operating temp. Folks who reengineere the thermostats and
run the fan all the time have and develope more blowby. If by re
routing a Crankcase vent tube you increase the cold engine cranckcase
pressure, you will develope leaks out the gaskets.

When you got to fart,,, Fart. who needs the added pressure
