I look at the pictures of 242 and I wonder how?
I have seen some sludge here and there. But some pictures simply make me wonder. Check it out .

true, i have seens some sludge but one of above pictures is something different. If you ask me how to replicate, i have no idea what to start with.

When I first got my '69 Firebird I pulled the valve covers and saw pretty much the same thing. I was going to replace the heads anyway, but what a mess. I don't know how people can neglect their vehicles like that.

It's simple! Don't change the oil for years and only drive it a couple on miles each time you start it. I've seen more of these than I care to remember. I bought a 62 Chrysler 300 convertible in immaculate condition with only 75,000 miles on it. I was told it had been owned by an old couple who only drove it to church and an occasional antique auction and when fixing a valve cover leak, I believe the story. The rockers had cut slots in the black sludge! After cleaning out both sides, I took the intake off and scooped the stuff out of the tappet chamber and poured kerosene thru to the pan. I had to probe the drain hole as the chunks blocked it until it came out fairly clean. Surprisingly, it ran fairly well even before I cleaned it up. After I had fixed everything I put another 100K miles on it. 413 cu. in. 4 bbl, pushbutton Torqueflite. I loved that car! This pic is not my car.

I can't say I've seen one of those before. That's a great looking car!

Definitely a chick magnet in my day! Leather seats, FULL leather that is. Flowmaster mufflers, ram air induction, Mopar high performance cam, A/C, great sound system. The only thing I didn't like is the rear view mirror on the dash! When she's snuggling up to you, you can't see a thing! My convertible didn't have the A/C vents on top of the back seat like the ones in the picture. Who needs A/C in a convertible anyhow? I bought it in 1973, had it for almost 3 years.

yeah the 300 series nameplate was around for a looonnnng time. I've always been such a classic car fan...worked on quite a few in my time too.

The 300 series started the luxury performance craze in 1955 with the 300 letter series. The letter series was special order and the cheap 300 series was started so people could enjoy the luxury without the cost of the performance package. The 62 model would have been the 300H with a 2 4bbl carb setup on 30" long ram tubes and 413 cu in displacement, a full length center console with 4 bucket seats. The most awesome of the series was the 57 300C with a 392 Hemi and 2 4bbl carbs. It set the land speed record for production cars on the sands at Daytona Beach that year. Awesome for a 5400 lb car!

Sorry, what were we talking about? We seem to have drifted....OH...sludge! Anyhow you should always drive a car at operating temperature for a minimum of 20 minutes every time you start it to allow any condensation in the crankcase to evaporate. If you don't, it will form a creamy white jelly that will combine with carbon and turn black, then become a solid. I know sometimes that's not possible, but you should at least take it for an extended drive at least once a week and change the oil any time the white jelly appears on the oil cap.
