I'm not in favor of the EGR system on that BEW engine, particularly the split-port butterfly valving on the intake, but for overall reliability, it has done very well. The cam seems to last longer than the BRM, but even then, I have several PD engines that we have installed replacement cams (usually swapped around 200k miles...) which have exceeded or are approaching 500,000 miles with few issues. The BEW was designed to run. If you keep these engines closer to their initial performance specs, I think even the injectors will last 1,000,000 miles.
Ioiceness, we will be in the shop, regular business hours this week. If you like, either call or email. I'd be happy to offer you an estimate.
