Oil runs cooler and returns to the crankcase faster if you leave the heads unvented. BTDT, proved it on the street and the race track. OK. Up to here everything was making sense. Now I see this from HAM saying oil runs cooler with UnVented heads. ??? (IMG:style_emoticons/default/huh.gif) Please explain. ...and, Is this using a single line from the Oil Filler neck to a vent box and back to where? or no vent there either? confused as usual.. Thanks (IMG:style_emoticons/default/agree.gif) (IMG:style_emoticons/default/WTF.gif) I , too , was ok with this line of reasoning , untill this.?????????????????? I have 2 ( two ) 1.7 engines , one has head vents the other doesn't, I was planning on using the vented head engine as the direction of this thread was logical as to the evacuation of crankcase gases is helpfull to an extent , espeacilly on carbed engines , which is what I have on both of my 1.7's. Now that the head guy spoke up and said it didn't do jack for the engine , I want to hear more of this new info please, Len ??? Jack / Jaxdream |
