Hey,
Some seawater is in my newly re-built MDIIB diesel (volvo), what do I do?
I changed the oil five times and the filter twice. Runs great otherwise.

Not for long it won't. Call the folks who rebuilt it and tell them they
have a problem that requires immediate attention.

You should have called them and followed their instructions before you
posted here.
