I asked an oil question a while back about my unfiltered 1942 engine and was told there could be up to an inch of sludge in the oil pan. That person was dead on as there was exactly an inch of sludge in my pan. It's nasty black mud that won't wash off. Couldn't believe it was that bad with only 31,000 miles. Surprisingly, aside from the pan the engine internals look pretty clean.

I had the same stuff in my 62. That gray stuff is lead from the gas I think.

I remember scraping that sludge out of the oil pan.  That was my first job helping dad with the cars.  I don’t see that so much in modern engines, I think it is caused by the oils back in the day.

I had the same thing in the sump of my '55 Buick that had only travelled 48,000 miles.

The engine was pulled down because of a rattling, which to a Buick expert was a cracked piston.   Turned out that the skirt of one piston was missing, and another cracked, but there was nothing seen in the bottom of the pan when it was removed.

When the pan was cleaned, in the 3/4" deep sludge was the remains of the piston skirt.

At least the sump in my '72 Eldo was perfectly clean when I removed it to replace the timing gear, even though all the cam gear teeth were missing their nylon teeth coverings.

All these parts were inside the oil filter pickup screen.   Luckily, none went any further.

I bought a '47 4 dr a number of years ago and first order of business was to change fluids. The oil level & pressure were good and the engine warm. I removed the drain plug and nothing came out. After sticking a screwdriver into the drain hole a small stream of oil started to drain. It took a lot of effort to get the pan cleaned out. As Bobby B says, welcome to the party.    Harry

A Billion years ago as a kid hanging around my local garage they "let" me work on cars.  Cleaning oil pans was one of the normal maintenance items done on most all pre-mid 50's cars.  Add so magic elixir to the oil, run the car for a few minutes and then drop and clean the pan. That was normal. You can see why.  Oils were very much different back then.

Without a PVC device to pull the  acid rain clouds and noxious blow by out of the "internals," the condensation of this toxic mixture simply creates sludge.  New engines not only have pvc devices and near closed crankcases, but they also run much hotter, thus burning of the condensation.  For those who run their engines at idle during the winter months, the potential to create serious problems is amplified.  James

Yep. Had the same in the 55. Amazing the drain plug even worked.

Good use for a borescope, pull the drain plug and look inside the pan.

I am glad to read this comment here, and firmly believe it to be absolutely correct.   I never exercise my car's engines in the Winter.. by starting 'em and letting 'em idle for a while.   Such running never gets the engines up to proper operating temperatures, resulting in increasing condensation in the crankcase.   I say, "No... wait until Spring!"

Seconded. :)

Yes, Agreed....No point in starting a classic vehicle if you're not going to drive it. I call it "Hibernation".........
