Yes, it's definitely a raw oil smell. Inhaling the airstream
coming out of the radiator vents from close up, even for just
a moment, causes a buzz, like having had a couple of
glasses of wine or sniffing glue.

They should have use something like this before putting the boiler on line.

A. Pre-operational Cleaner: All systems shall be flushed with
water prior to chemical cleaning. Use water meter to fill, record, and tag
(permanent tag) the system with the actual system volume. Chemical cleaner
shall be added to remove grease, mill oil, organic soil, flux, iron oxide
etc. All terminal control valves and valves at end of runs ("dead legs")
shall be opened so that cleaner is circulated through the whole system.
After cleaning, all strainers shall be flushed, and strainer screens cleaned
or replaced. Once closed loop is chemically cleaned, system shall be dumped
and flushed with water so that all cleaning chemical is removed from the
system.



B. Chemical treatment: Shall be an alkaline, buffered,
nitrite-based corrosion inhibitor, maintained at proper levels to prevent
corrosion to the system.



What you can do now to help is to blow down the boiler frequently, a few
times a day. That will help replenish with fresh water and dilute what
residue is in there. In most cases, there is a drain valve on the boiler
that is piped into either a drain or sump to be pumped. You slowly open the
valve while there is pressure in the boiler and drain some of the water.
There should be an automatic feed system to bring in new fresh water. Never
take it down more than an inch or so at one time. There is a sight glass
showing the water level and some sort of permanent mark on the boiler or the
water column showing the minimum level.

BTW, I didn't even notice you had an accent
