I have an '86 E-28 with the M12 Universal. I replaced the impeller on the Oberdorfer raw water pump at the beginning of the summer, and had no problems. However, today I noticed a water leak coming from the seal where the pump mounts to the engine. I tried to tighten the 4 cap screws, but that did not help.
Any ideas on what this might be?
Thanks,
Andy
