Changed Inga's Oil today and was backing up to check for oil spots and there were! In fact there was a fairly steady steam of oil and its coming off the passengers side of the engine from the oil filter and sending unit area.

There has been a little oil leak from I suspect the dual pressure sending unit for a while. Had another Mann Filter and bit the bullet and replaced it. When I did made sure nothing was scratched on the surface and that the old seal was not still in place and it all looked good. Checked an I still have the leak and it's just as bad.

Anyone ever had a dual VDO Sending unit have a leak? Waiting for the manifold and car owner to cool off before pulling it. But is there anything else I might be missing?

Did change from Castrol Syntec to Mobil One this oil change. Mobil One is a whole lot cheaper right now ($8 less for five quarts) than Castrol for some reason. Pretty sure that this is not the cause of the problem however, Inga has been running full synthetic for a while now.

Thanks in advance for your help,

Paul
