New problem just cropped up for me with my 90 Vanagon. I seem to have a significant loss of power both when engine is cold and warmed up. Recent maintenace included replacing the ground strap from block to ignition coil, cleaning up contacts on the ignition coil, new rotor, distributor cap, new spark plugs and wires, new air filter, recent oil change. Checked throttle position switch and this is ok. Idle stabilizer is working. I then checked for vacuum leaks and replaced vacuum line from fuel pressure regulator to intake manifold because this line looked suspicious although I think it was ok. Next I pressurized the intake system with air found a leak coming out of the oil breather pipe. This is the large black plastic pipe that sits on top on the engine with a line that goes from it to the air intake hose just after the AFM. This black breather pipe is not supposed to be vented in anyway to the atmosphere---Correct? Because of this I suspect I have an air leak into the intake system after the AFM (false air) which may be leaning the air/fuel mix. Has anyone had problems with this pipe? Mine seem to be leaking near the top ridge just under what looks like a cap on this pipe but it is not removable from what i can tell. Any suggestions appreciated. TIA Tim -- |
