I've discovered something else I don't know much about. I crawled under my car to get a look at a small oil leak I've developed. Not much just a dozen or so drops since last Saturday when I drove her to a wedding photo shoot.

There was some buildup on the front (toward the front of the car) and top of the CB Performance Thin Line Sump. I could also see some buildup above that as well so I don't think it's coming from between the new sump and the bottom of the motor.

Here's a photo:

Of course I cleaned it all up because I was embarrassed for anyone to see my dirty sump. The buildup was right where my finger is pointing and on the area above it where the split is at.

Is this anything to be concerned about?

If you're not living life on the edge, you're taking up too much space!

Robert, Al's suggestion to put cardboard on the floor is a good, time-honored fix for oil leaks.

But a better one is the two catch can method. This collects the dripping oil in one can that is poured back into the engine when about half full. The second can is put on the floor to catch the oil that drips while you're pouring the contents of the first can in.

As long as you can pour oil in the top faster than it comes out the bottom, there's nothing to worry about.

The only one I know who has no oil on the bottom of his engine is Troy Sloan. And that's because he takes all those pretty pictures of his sumps just after the engine is put back in the car and before there is any oil in it.

 

The obvious points, Robert, are the flywheel seal, cam plug, oil passage plugs (especially if they were pulled to clean the galleys at last rebuild and now they've been replaced with screw-in plugs), and at the engine/sump seal (a cheap paper gasket that doesn't have any sealer on it will start leaking after a while as well). Not very often will an engine start weeping between the case halves (although it has been known to happen).It could also be the transaxle main shaft seal- what's the oil smell like? Was the engine rebuilt or messed with (for example, heads taken off) recently? Does it look like it could be coming from the bell housing? I believe Rancho (and maybe others) drill a 1/8" hole in the bottom of the bell housing so a mainshaft seal leak doesn't build up, get thrown around and soil the clutch, which I think is a good idea. They also drill a couple of 1/2" (I believe) holes in the top to let heat out on some builds they do. 

If it's small (and not trans oil) then you can certainly wait until the car is off the road and this would be a project for that time. If it's trans oil then it's just a matter of time until it does get on the clutch and you're replacing a disc (and maybe the pressure plate) and possibly re-facing the flywheel. Al

PS- Whether you're a poopie head (or not) remains to be determined...

BCB - Green Brad Penn not synthetic

Meade - 25,000 miles. I've put 10,000 miles it since I got it.

BADSPD - 1.5 years. It was one of the first things I added. I was thinking about redoing the gaskets before I noticed the leak. I was considering some type of sealant. Any thoughts as to which one?

Al - Definitely green Brad Penn and not trans fluid. No recent work (no work that I know of) that required the heads or any other parts to be removed. I did the pushrod tubes but I checked them and no leaks. I thought it might be coming from the area above the split in the case where my finger is.

If I proclaim I'm not a poopiehead often enough people will believe it even if it isn't true.
