I remove my sump mounted oil level float as it was not showing actual oil levels, (always read full), and discovered that the float arm and float had detached from the oil level rheostat housing and was resting on the bottom of the oil sump. On inspection of the float the solder joint for the float arm had cracked and allowed oil to enter the float. The set screw fixing the float arm to the oil level housing had loosened allowing the float arm and float to separate from the housing.
Removing the float from the float arm a small amount of oil drained out, however, the weight of the float indicates that solidified oil crud has built up in the float. Several fills of the float with solvent have not been effective. I would like some suggestions from the group as to a more effective method and what soldering method should be used to reattach the float to the float arm so that this doesn’t reoccur.
