15 Mar Anomalies
We’re in limbo as we wait for a Mass Airflow Sensor. Trouble-shooting the causes for our intermittent engine stammer has been a long process and, although it has been a necessary step toward getting the Rover ready for a 15,000-mile journey through the Americas, we’re ready to continue exploring Mexico.
As we take a closer look at the engine and the electronics, however, we’ve noticed some faulty mechanical and electrical work – unexpected anomalies in the wiring and belts. We’ve always been eager to continue moving forward after something fails on the road in Mexico or Central America but some of these quick fixes may be catching-up with us.
About a month ago, I was discussing the engine with a friend and Rover enthusiast, and we were looking down into the bay as we spoke.
“That belt is on incorrectly” – he said.
And he was right. Somewhere along the line, as various shade-tree mechanics helped us along, some odd decisions had been made. In this case, we discovered that we had one belt running from the crankshaft, sliding over the power steering pump, to the alternator. We should have two different belts going from the crankshaft & alternator to the power steering pump. Our current configuration looks something like this:
A year ago, as we were overlanding through Guatemala, we learned that one road-side workshop had removed our air filter & the lid that holds it in place. We bought a new air filter and fashioned a lid to keep going but it was irritating; we would not have driven so many muddy/dusty miles without a filter and finding the screw-on lid in Central America was out of the question.
The bottom line is the more you know about your vehicle, the less you’ll have to deal with stuff like this. There is no substitute for doing your own research and doing as much of the work as you can.
