Leak

My money is on the rear of the pan.  It is an easy in car fix too.  I did it on our 67 when I dropped a socket in the dizzy hole!

It could well be and I was thinking that yesterday evening due to oil being on the back lip of the pan and where the oil is coming out. 

But I did notice it appears the plug has a leak also, more of a seep really.

Oil leak shouldn't be that hard to spot on a pretty much clean motor but then the oil is super clean to almost the point of clear.

If it really starts ticking me off I am half tempted to buy some of the UV dye and a black light  :)

I've noticed a spot of oil once or twice and I've been trying to chase it down.

Think I know where it's coming from now.  It seems to be coming from around the transmission inspection plate.  If I wiggle the inspection plate it's "wet" for lack of a better way to put it.

It's oil for certain and not tranny fluid.

I think I know the answer but any chance it could be anything other than a rear main seal?  I checked where the heads meet the block and no signs of leaks there.  Didn't think to check the back of the intake though.

Motor only has 200 or so miles on it so I am a bit po'd that it's leaking oil from anywhere.  It's not a massive leak but still pretty annoying.

If the galley plugs are tight and the intake and vc's are dry following down the block from the top.
Leaks from the rear are left to crank seal, rear main cap ends or pan seal.
My 2cts is is coming from the rear main cap ends.  You describe leak occurs when run and not standing.
The warm oil under pressure seeps out the end of the block at the cap sides and
It works its way down the block plate/oil pan annoying the heck out of you.

Pull pan and end cap and reseal or keep kittyliter around.

Well...the boys and I took the car to the local car club cruise in last Saturday night and by the time we could order a pizza and get back outside to find a table there was a small puddle under the car.

Today, we took it for a 10 - 15 minute drive.  It was running temp, etc.  I made sure to give it a mix of some hard off the line acceleration and some normal driving.

Got home and it leaked a single small drop.  I put some news print under it and at an hour later still no leak.  Going to wait and see what it does overnight....I left the news print under it.

I haven't really done anything to it.  Only thing I did the other day was grab the oil filter and try to turn it to make sure it was snug since I had just changed the oil.  The filter seemed to be on pretty tight already and didn't really move at all...also didn't see any signs of it leaking but just to be thorough figured it couldn't hurt.

We'll see what it does over the next few hours / over night and go from there.

scratch that it leaked again.  Guess I'll try pulling the pan when I get a chance.

If you have the spare change I would recommend getting the one piece Felpro PermaDry oil pan gasket.  Be sure to use the 4 push-pins into the block to hold the gasket in place while you raise the oil pan up.  No sealant is needed with that gasket and it is reusable over and over.

I am going to try taking the pan off first.  I tend to lean towards Felpro gaskets whenever possible due to reusable, etc. 

Figure it's a project that won't take "that long" and might solve the problem.

when you pull the pan off, check the flange to make sure its straight.  I had a ford racing pan that had a wave in it and caused a leak.  Good luck

 And you never get it as pretty again either after you booger up the bolts taking stuff apart again.

Ain't that the friggin' truth.  This is something I always hate and pisses me off to the extreme after taking so much time and care to paint/polish and fix up everything.  ughhh.  :fbomb

[RustyRed]

I spoke with the guy that built the motor and he said his first thought was the pan gasket. 

I ordered the new Felpro gasket.  We'll see if that fixes the problem.

Make sure you check the mounting flange on the pan.  Maybe it isn't straight.

I'll check it when it's off.  The pan is one I found on ebay so who knows.  I seriously considered buying a chrome one new for roughly $40 today to throw on there.  Not that anyone ever sees the underside of the car but it might look pretty nice under there with the Trick Flow tranny pan...and while I have it off and all, LOL!

[guruatbol]

I put a chrome one on the 67.  I like it.  When I clean the underside it is easy and makes me feel good when it is done.  It does look good.  No one looks under there but me, but it still looks good.

I have a chrome one on the '66. When ever someone looks under the car....the comment to their friends is "WOW....look at that...he even has a chrome pan". For some reason, some really get excited about it, but then again, this is redneck country. It is easy to clean too.

[RustyRed]

Main reason I was kicking around the new pan is because the one on there now was freshly painted in October and already has a few chips and generally looks kind of crummy.

I just might order a chrome one but it is rare that anyone would look under the car besides me.

[lethal289]

Even check the new one.  I had a chrome ford racing unit with a wavy flange.

I bought this aluminum pan from Laurel Mountain.  I think it was on sale at the time for about 90 bucks.  It looks ok, how it works as far a leaking is yet to be known! If you ever do call them, ask for Kevin and tell him I said hello! I've bought just about everything on my stang from them.  my hedders look so neat!!

Personally, I'd be leary of a $40 oil pan.  $40 doesn't get you a lot of quality these days.  While the pan may look nice... out of the box.... it's doubtful that a $40 chrome oil pan will look good a year after installation.

What you're really looking for is a quality part designed with a thicker.... and straight.... mating surface.  Quality parts will cost you more initially, but in the long run will save you a lot of time/energy.  Nobody enjoys R&R'ing an oil pan on an installed engine.  Do it once and be done with it.

This is a popular oil pan and the one I'm using.
