Series 50 EGR with blow by. What's cheaper, fixing the engine or replacing it?
I bought a bus with a series 50 EGR engine. Sadly, it has a lot of blow by and is most likely on it's way out. I have a spare series 50 engine, but it's non-EGR. What would be the most financial sense option, replacing the series 50 with a non-EGR series 50, or just fixing this engine that's currently in it?
