Mike's runaway idle problem occurs even if you increase the rpm with
your hand at the injection pump. The rpms increase and when you let (or
force) the pump shaft to return, the rpms don't slow down. Turning off
the key and restarting without touching the throttle, the idle is fine
again. Removing the dipstick, there is no apparent blowby pressure in
the block. Nate from the Diesel list suggested disconnecting the valve
cover breather hose and this sounds like a good test to see if engine
oil is being supplied as fuel through the intake. The engine has good
power and in a Diesel Westy any
power loss is noticeable. There is no unusual smoking. Any other ideas?
