So I'm getting to know the genset on my boat. I know the prime mover is an 1995 Perkins
103-07/Perama M20. After cleaning
up the nasty mess in the lazarette where it is mounted, I routed the crankcase breather into a plastic bottle. After running the engine
for about 20 hours, I can see a small amount of oil
, which I expected. When I hold my finger over the breather with the engine
running, it will build up pressure over about 15 seconds, enough that I can feel the air running out when I let my finger off. So, I have some blowby.
Is this something that I should expect in an older engine, and can live with for months or years, or is it a sign that the diesel
is on its last legs and will soon give up the ghost if I don't do a rebuild
