Dandy Dave Posted November 6, 2014 Share Posted November 6, 2014 This may be a good lesson in the importance of changing your oil. And also in having detergent in modern oil. It has been a few years or more since I opened up a motor so gunked up with Sludge. Dandy Dave! Link to comment Share on other sites More sharing options...
Dandy Dave Posted November 6, 2014 Author Share Posted November 6, 2014 Ahh, Did I mention that the motor is a 1939 Oldsmobile 230 CID engine. They must have used GLF motor oil in it back in the day... Dandy Dave! Link to comment Share on other sites More sharing options...
Laughing Coyote Posted November 6, 2014 Share Posted November 6, 2014 Ah yes. The memories of what my engine looked liked. I can smell it from here. Link to comment Share on other sites More sharing options...
55 SURVIVOR Posted November 6, 2014 Share Posted November 6, 2014 Dave; The oil capacity must have been about A 1/2 quart!!!!!!!!!!! Mark Link to comment Share on other sites More sharing options...
Guest buickkuhn Posted November 6, 2014 Share Posted November 6, 2014 Neglect still happens today even with todays oils . This is a 2006 4.7l chrysler engine that the timing chain tensioners quit getting fed with oil to apply pressure. Your right LESSON of the day change your oil 3 months or 3 thousand miles .You can see where I scraped the timing chain mount , and that new oil filter was 2 days old - He thought he would change the oil and surprise it did not help .

barry22 Posted November 6, 2014 Share Posted November 6, 2014 Did the owner say how much time was between oil changes to allow the engine to look like that? Link to comment Share on other sites More sharing options...
Dandy Dave Posted November 6, 2014 Author Share Posted November 6, 2014 Also, if an engine has an oil filter, it is only good if it is not plugged and the oil is dumping out of the bypass valve. I wish I had photos of a Massey Harris 44 Special Tractor engine I rebuilt about 35 years ago. I took the totally plugged filter out one piece at a time with a hammer and screw driver. The consistency was like road tar. No way any oil was going though that. Yup, Change your oil and filter often. This 39 engine was last run around 30 years ago. The owner said it did not knock or smoke and ran smooth when they pulled it from the car and put it in storage. I told him that pulling the pan and side covers was a must. He is now glad I did. Also, critters were in the upper radiator hose and the head and block was full of seeds and nuts. Getting a complete gasket set and going though this engine has definitely saved it. Dandy Dave!

DonMicheletti Posted November 6, 2014 Share Posted November 6, 2014 All perfect examples of why you should drop the pan on an engine that hasn't run in a long time. Changing the oil on those engines woubdnt have helped a lot and would have led to disaster. Link to comment Share on other sites More sharing options...
plymouthcranbrook Posted November 6, 2014 Share Posted November 6, 2014 I bought a 1989 Ford Escort from a co-worker at the time in 1995. He had bought the car new and it had about 50,000 miles on it. Apparently I found out later that he only changed the oil twice in that time. I used a vacuum to suck up the chunks I chipped out from the valves and upper head. Changed the oil a couple of times while I had it. It was totaled about 6 months after I bought it and maybe that was a blessing. I guess it is a testimony to Ford 1.9 engines that it did not die earlier.

Guest Posted November 6, 2014 Share Posted November 6, 2014 One other thing that contributes to oil sludge is improper crankcase ventilation. Link to comment Share on other sites More sharing options...
jrbartlett Posted November 6, 2014 Share Posted November 6, 2014 One other thing that contributes to oil sludge is improper crankcase ventilation.Another contributing factor is running an engine too cool -- i.e. without a thermostat. The engine has to get warm enough for the water to evaporate out of the oil so it can exit through the ventilation system, whether road draft tube or PCV. The presence of water in the oil is a contributor to sludge formation. Link to comment Share on other sites More sharing options...
55 SURVIVOR Posted November 6, 2014 Share Posted November 6, 2014 All good points!! Good article Dave. Mark Link to comment Share on other sites More sharing options...
Dandy Dave Posted November 6, 2014 Author Share Posted November 6, 2014 Thanks All. Yeah, This old 39 Olds engine was not venting at all. All the holes going to the valve train were covered in one, to one and a half, inches of gunk plus. Also agree with running with a T stat. Dandy Dave!

Rusty_OToole Posted November 7, 2014 Share Posted November 7, 2014 Looks typical of an old motor with a carburetor, that was run on leaded gas. Link to comment Share on other sites More sharing options...
