Slobber tube - cheap fix for blowby
Shane it sounds like a good plan. BUT, I fear that reengineering the
vertical path of the tubes with a horizontal turn will add the grave possibility that crud will buildup and block the process. MikH posted a link to an article which describes the Scavanging process on the 2 cycle DDV92's. The Scavanging is blown out the Slobbertubes. http://www.yachtsurvey.com/comparing_die...es.htm#TOP The engineers design engines to operate optimal at a given temp. That temp is controlled by a specified thermostat and fan cycle. WHen the engine is cold or run cold the tolerances are out of planned specs and the crankcase gets internal pressures. If you hold the crankcase pressure in it will come out the weakest spot which is around the tin pan and weaker gaskets. The other paths will weep oil dynamically even when op temp is reached I correct the drops of oil on my toad with windex and detail spray GregoryO'Connor 94ptRomolandCa --- In WanderlodgeForum@yahoogroups.com, "sfedeli3" <sfedeli3@...> wrote: > > On my 85PT40, I routed the slobber tubes to a horizontally hung 30" > long piece of 4" PVC with end caps and a drain in the bottom.
