Has anyone ever heard of an oil pump getting loose? My 225 uses a fair amount of oil and I don't believe it's being burned...I think it's leaking. When I got under it to look the only "wet spot" I saw was the area around the oil pump...I saw some evidence of drips and leaks, with a drop or two still hanging on the pump. Although I've never heard of a pum,p working loose, could it be this is the source of my leak? Are the torque specs for the pump critical, or should I just snug them up a little and see if it helps? Davey

Yes you can snug them up a little if you want, just don't go crazy,gunk motor and re-inspect, check oil sending unit it is down there to, easy to replace just a few bucks,we have replaced some pump gaskets pain in the ba booka when in car. Most had 100,000 milles or so. Hope this helps.Don

The pump-to-block bolts could've loosened up and/or there could be a leaky gasket there, but there are a bunch of potential leak points around the oil pump to check out. The oil filter-to-pump junction is an obvious one, and the oil pressure sender screwed into the rear of the pump can leak right through the body of the sender. At the other end of the pump is the pressure control valve cap, screwed into the front of the pump with a gasket under the head of the cap. And then there's the 5-bolts-and-O-ring junction of the pump cover plate to the pump body. So, it will probably be easiest if you power-clean the whole area with Simple Green or another effective degreaser to get rid of all the old built-up oil, add a bottle of UV-fluorescent dye to the engine oil, run the engine/drive the car for a little while, then shine a blacklight on the area to pinpoint the source(s) of the leak. The specialty UV detection lights are often sold at very inflated prices; I made my own on the cheap by simply replacing the ordinary F15T8 fluorescent lamp in my Sears fluorescent droplight with an F15T8-BLB "blacklight blue" lamp. Works great! That said, it looks like prices have come down on the detection lamps since some of them have gone to LED technology; here's one for $40. (the yellow "fluorescence enhancing glasses" are kind of a crock; they're not needed...the dyed oil will jump WAY out at you under blacklight UV without any special goggles.)

Too many people who were born on third base actually believe they've hit a triple.

Never seen one work it's way loose, but there is a first time for everything.

Could be the gasket. Yes, there is a thin gasket between the pump and the block. I've experienced that leak. (yuck)

I once had a leaky oil filter installation that looked like the pump leaking, but was just dripping down. At least check them for tightness. If they are tight, I doubt they'll turn till you are way past the spec, and if you have to go that tight, the pump or gasket is likely to be bad.

Oh yes, there is also a cover plate on the pump with can be removed and may be the cause of the leak.

I'd say to use some foaming engine cleaner and then get a clean look again.

Found this http://www.hamtramck-historical.com/ima ... 71-9-4.jpg in my favorites folder...may be a solution. One I plan on doing since my pump has been leaking since I replaced mine with a 5 bolt Meldon unit.[/code]
