Having worked early teen years at a gas pump along with completely overhauling an auto engine
at that time, one would expect reading oil
level on a dipstick as quite elementary.
However, that is exactly the problem with my 1999 Yanmar
4JH2E in a 40' Island Packet
sailboat. To aid in consistency, oil
is checked the morning following a significant engine
This mornings attempts to determine oil level were typical. Initial pull of the stick displayed oil approximately eight ounces over the full mark. Wiped the stick, slowly pushed it back into normal position and waited 30 seconds.... withdrew the stick... down 16 Ounces. That can't be correct! ...only ran the engine two hours. Wiped and checked again... waited 10 to 15 seconds and it read several ounces below full. that would seem to be the correct level. Can we try for a confirmation... wiped and reinserted the stick.... down 10 ounces this attempt. I give up!
All of my reads are on the face of the dipstick because the reverse side consistently reads a half quart lower. ...and no, the boat isn't rocking significantly.
Any suggestions would be greatly appreciated.
Thank you, Bill
