I have a similar problem with a few drops of oil on the floor each morning from the oil pan. I can't see any trail of oil from high up, but this weekend I did see one of the pan bolt with oil on it, so I think it may be the pan gasket leaking around that bolt. . . I had wondered about the potentially porous cast aluminum pan, but that seems a little crazy.
 
Other than the couple drops over night, the '99 van uses no oil at 104k miles.

I also have a 99 Venture. I had a similar problem for years, where coolant level would slowly drop. But I never had any evidence that it was leaking into the engine. I finally spotted where it was leaking from the intake manifold gasket to the outside of the engine. It is a common problem to for the intake manifold gaskets to fail on these engines. I finally had mine replaced, for fear of a leak developing to the inside and ruining the engine. It cost me nearly $1k to have the job done.
If the dealership told her it was a sensor problem, they were likely deceiving her. You can read about this problem all over this forum, going back a number of years.

2001 Chevy Venture
I have an oil leak in the front of the engine left side over the starter. The leak is only when the engine is running and is a solid stream ~ 3/16". It does not appear to be coming from the pressure sending unit. Does not appear to be coming from any gaskets or valve cover. Do the ventures have any exterior oil hoses, like to an oil cooler? Is the location of the oil pressure sending unit over the starter? It is very difficult to see exactly where it is coming from.

I have had a slow intake manifold leak for the last couple years on my '00 venture. I have never seen any coolant in the engine oil. I keep reading about engines being ruined from this defect. Is it possible that my leak is only external(which it appears to be), or is the coolant destined to reach the engine eventually? How much should I expect to pay for this repair? Thanks.

I think you should get the gasket replaced soon. I had it replaced on my '02 Venture (may not have really needed it -- they later diagnosed the leak coming from the head gasket) and my '00 Pontiac Grand Prix. If you let it go too long like I did, you could end up w/a warped intake manifold (grand prix), which costs much more. I think I paid something like $1000 to $1100 for the intake manifold gasket on the Venture (can't exactly remember). There is quite a bit of labor involved to get to it (not as much as the head gasket, though). But I would get it taken care of. Keep the receipts as there might be a recall. I was refunded for the Grand Prix as there was a recall issued for the 3.8L V-6 fasteners. They refunded the cost of the gasket, new intake manifold, and labor.

#10 of 14 Incline Oil Leak 98 Venture by ahowler

Ok I have a driveway that is at about a 50 degree angle when I back down and park on the incline to hitch up my boat I have a bad oil leak. I took it to the shop spent $900.00 for oil pan gasket, sensor, rear seal, and filter seal. Took home and I still have the leak. Anyone else have this problem and did you fix it. By the way it has a 120,000 miles on it.
Thank You

#11 of 14 03 Chevy Venture Oil Level Low by OzAkman03

Jan 11, 2009 (8:50 pm)

03 Venture, 93K miles on it. Bought used and in good condition about a year ago with 80K miles or so on it. Just recently I had my oil changed in a place called MGM Oil in south Jersey. Great place with quick oil change and I used them for years. In this recent oil change yesterday, they told me that they could not find a reading on the dip stick when they were checking for the oil level just before changing the oil. This kind of scared me, I hope this does not mean I have the common problem for this engine the gasket needing to be replaced? I do treat my Venture well, and I do take care of it. I will keep an eye on the oil level, but how can I tell before running into a bigger problem, I never find any oil leaks under the van, the van runs fine.
 
Any ideas?

Don't freak out...you might be starting to burn a little oil - just keep an eye on the level.
 
If your intake manifold gasket was going south, you would have found antifreeze in the oil and your AF level would slowly go down.

If anyone is still interested in a response to this question, I ran into the exact same problem (sounds like)...
 
Oil pressure switch is directly above the starter. Jacked the car from the passenger side and you can see a steady stream of oil coming off the connector into the pressure switch. Replaced the switch (costs about $7 at AutoZone) and leak went away. You'll also need a special socket to get this thing off, so pick that up if you don't have one.
