I discovered sludge/blockage in my crankcase breather hose while rebuilding my "84 Vanagon GL 1.9L. Now I suspect problems downstream. There is no vacuum at the throttle valve housing fitting (early version), for ignition timing retard. Is there anything I'd damage inside this fitting if I attempt to push something through it to "unblock" it? Are there other items in this area susceptible to blockage from any sludge that may have made its way through the crankcase breather hose? The engine I rebuilt from was full of sludge. The PO said he used a local store brand oil. When I dismantled the engine, it had uncirculated new oil near the oil filler that could not reach the crankshaft because of excessive sludge blockage... 2 piston rods were seized to that crankshaft.
