General Maintenance & Repairs - Motor oil drip

I have a '99 Z with an annoying drip from the back of the motor. It leaves only a drip every couple days but the pan is now a mess. I've looked it over, had it up in the air and hanen't been able to find the source. The only major work on this car is a tranny overhaul. It has almost 130K miles. Any experiences would be a lot of help.

Probably the rear main seal

X2 that would be a good place to start, and if you have a hard time finding it, you could try that additive that you put in the oil that makes it look neon when you wear the yellow glasses that come with the kit. If you add that stuff and check it daily it will make any oil leak noticeable enough for you to trace the source of it

How about the valley cover or something like that. Any other oil seepage experiences ao I could look?

There is also the oil pressure switch. I believe that is where my engine is leaking from. I need to pull the intake manifold and valve covers to replace the gaskets and take a look at the switch.

Is it a big job to remove the manifold from a Camaro?

Nah, you just have to be real careful removing it b/c a vaccum hose runs from behind it, around the oil sending unit, to the brake booster. It's extremely easy to break the sending unit, even knowing to watch out for it.

Is there coolant in the manifold like my old fords & Chevys?

YUp...thats what I would consider the culprit.

You can reach it without pulling the intake, just snake your hand back there and feel around for oil. I got big arms and I can do it.
