The Toyota parts diagrams stop at 69 but in fact they show setups pre-69 sometimes. The routing on the top diagram is actually correct! Just imagine the carb base being a single port carb base and not two .. The hose attaches to the PCV (which is attached to the oil filler tube as indicated), it runs up and over the valve cover (being held by the hose clip on the first valve cover nut) then down to the carb base port. Here is a very old pic of my engine back. You can see the PCV hose routing. The one thing I was missing at the time was that hose clip which is retained by the first valve cover bolt:
Yeah I can get one later no problem. The OG one is made of some phenolic fiber material that can crack over time. I believe Mark @65swb45 sells a machined aluminum one. Maybe he can tell us if it has the PCV port built into it? I cant remember.thank you dudes !
is there a view of the carb base ? don't have it
The first on that you posted is the one that is correct for the F135
i have the old style oil bath air cleaner... and the engine i found to install have thoses slits on the valve cover, so what will be the good setup finally ?Actually not all F135 had that one. With slits on the valve the other one would have been correct. With actual PCV valve you will be moving more volume out the crankcase. The downside is the make up air thru the valve cover is not sized or filter the air the style with tube running to the air cleaner. At one time had a few cruisers with the draft tube style on the oil fill neck. Those are all sold. Have some early oil bath air cleaners but never paid attention of they all had the tube for the hose going to the valve cover.
