I got 205, 000 miles on my 1.9 WBX in my '85 GL. Next van, an '88 GL, I
only got 89,000 on the 2.1 WBX in it before it blew. The replacement
engine, which I am now running from new, has 160,000 on it and going
strong. It's showing an oil pressure fault that appears to be a sensor
system malfunction rather than a problem with the engine. Hope to get
200,000 out of it.
