Keep in mind that burnt piston was the result of something else being wrong. It was running lean or the ignition timing was over advanced. Long before it melted and blew it was knocking and pinging asking for attention. A problem with the Waterboxer and its location the knocking wasn't heard but it was there. Point is that was not a result of a bad engine and it was probably avoidable.

MY '88 had three engine in the vans short life. The first was the factory engine when the vehicle was new, before I bought it ftom used car lot. When MY engine failed at about 89,000 miles ( burnt and failed piston) there was so much metal that went everywhere, that upon being offered "a deal" on another engine (the current one) I took it. Still running strong at 160,000 miles and 15 years. That made three engines at 89,000 on the van. Before the engine failed, I had always thought it to be the original engine. On teardown ( the one that failed) a yellow tag was discovered on it that said Remanufactured by Volkswagen of Canada. At that point I knew it was engine #2. The tear down was finished, an I opted to buy engine number 3 from Jim Connel at JIM'S AIRCOOLED in Leeds, Alabama, which is close by. He's building me another engine for another van as I write.

So thats the summary of my engine episodes.
