differences in early 99
Only bad flaw with the early 99 is the same flaw most PSDs have, but it’s worse on the early 99 so look carefully before buying, the factory air box and intake can leak dust into the turbo and engine. Mine was this way when I bought it with 130k on it. I wasn’t as smart as you and I didn’t research before buying so I didn’t know to look. I wound up having to replace the turbo and rebuild the engine.
Wow ,what happened that you needed a rebuild?
