Bad oil leak

My '86 Spider "Dinsdale" leaks oil continuously when parked. I thought the large oil pan contained all of the oil when the engine is off with only the drain plug as a source of leakage. Apparently not. Any ideas?

There are many places for oil to leak from. Your leaks could be running down the block then finally leaving the car from the pan. You should clean up the engine as best you can and then look for the sources.

Probably coming from higher up on the motor. You don't see it dripping till it sits, then all of the oil runs down the side of the motor and drips on the floor. Do what Alfaparticle said.

It leaks continuously. It's not just running down the side of the motor - if it sits for a month I can lose a quarter of a quart

The Spider oil pan has two gaskets - because it is built from two vertical halves. The middle gasket might be leaking.

Also, are there any nasty dingers on the heat fins, from curbs or road debris? Maybe a cracked pan.

You need to look & clean it up with some strong degreaser to check it out.

check by hand that the oil filter is not loose.
Even when sitting that still contains a fair amount of oil (as we know when we replace them and it spills out all over the place)

but yes, a good clean up will soon show where it is coming from.

Clean and wipe the entire oil pan and the finned plate at the bottom, then look for seepage. It is common for the oil pan to get hit while driving and crack either at the bottom finned plate or even the top part. But it also could be just a bad gasket or a bolt holding the bottom finned plate on that leaking.

If all of the above fails, I have had good luck with a UV Leak Detector Kit

You add dye to the oil, put on the stylish yellow glasses and shine the UV light around the engine bay in the dark after running the car for a bit. The source of the leak(s) is usually pretty obvious as the UV light makes the dye in the oil fluoresce.

Best of luck!

I can't stand oil leaks!

As mentioned, there are soooooo many places our cars can leak oil. So many!

This UV kit is THE FIRST thing I would do.

Trust me, it will save you hours of time trying to determine the real source of the leak and $ replacing the wrong seals.

Good luck,

If true you must have a leak in the oil pan. There isn't a quart of oil above the dip stick. Regardless you need to do as suggested and clean up the motor. It you have access to a lift you should be able to pinpoint the leak. Using UV dye is also a great idea.

These are wet motors and the old adage holds true that "You should only really worry when it stops leaking.". But that's a lot and need to be dealt with. Unfortunately the cost to fix it will likely be a lot more than the cost of a quart of oil.

As you mentioned yesterday that "it's not just running down the side of the motor" would indicate that the 6 rubber "O" rings in the head gasket have deteriorated or collapsed and is causing some of your oil leak. As everyone has said, clean the engine very well then go looking for the oil leaks. I say leaks because I believe you have more that one oil leak. ATB, Chief
