63 Oil Pan - What is that

[Harry S.]

A strange one. Removed the pan to change the rear main seal. All I have used is Rotella T4 for the last 10 years. I spoke with the prior owner, he has no idea what it is.

I put my spare pan on so I can clean this one.

Anyone what to take a guess?

Lead from leaded gasoline or, possibly, zinc from oil.

Looks like tin plating, Harry, no idea how it would get there...

My question for you is: what process at Flint painted the tip of the drain plug?

Re: 63 Oil Pan - What is that

Of course I will take the opposite point of view from Joe only on this subject. Don't know if you use the current gas available with the ethanol added but if you do it could be the culprit on this unusual coating. See below>

Alcohol is corrosive and can degrade plastic, rubber or even metal parts in the fuel system that weren't engineered to use alcohol-bearing fuel. Consequently, that antique Evinrude outboard or '60s lawn tractor you bought at the swap meet might need some upgrading to stay together on today's gas. That means corrosion-resistant tanks, alcohol-tolerant rubber lines, seals and fuel-pump diaphragms, and plastic fuel-system parts that won't swell up in the presence of alcohol. Vintage boats with internal fiberglass tanks often have issues with the coating inside the tank failing, *sometimes requiring massive structural modifications. Highly tuned two-stroke engines will run leaner (and consequently hotter) on the lower Btu/gallon alcohol mix, potentially leading to melted pistons and scuffed cylinder walls. Alcohol will also scour varnish and deposits out of the fuel system that have remained in place for years, which will eventually wind up in the filter or main jet, choking off the engine's fuel supply. Worse yet, the alcohol itself *oxidizes in the tank and produces a tenacious brown glop that's far more damaging to fuel systems than the *varnish we're used to seeing in pure petroleum fuels. In warmer weather, you can see varnish starting to form within a month of dispensing fresh fuel into a vehicle tank or storage can.

I do see the bottom of some fuel injection Fuel bowls with white residue. From ethanol Harry.

NICE REPLY. We all need to use ethanol free gasoline our old cars.

Try to find it in many states, especially California. In addition, finding it when one needs it on any significant road trip is virtually impossible.

Been away for 5 days. Thank you all for the comments.

Got a call from the engine shop today. They believe it's white paint. We'll clean it up and reuse it.
