350SD, oil consumption worsens
I own a '91 350SD with 286K miles on the clock. For those that don't know, I have been monitoring oil consumption tendencies from over 1 year ago in August. From there, consumption was 1500 miles per qt. on average. Consumption has steadily increased, and the last fill noted the 250 mile per qt marker. I have no idea what's going on. Could valve seals be out of the question for cylinder #1?
Here is a comparison. One soundclip is in normal speed. Comparing a 3.0 liter OM603(not mine) that needs a new set of injectors to my 3.5 liter(2nd half of sound bite). http://www.ejzcars.com/350soundnorm.wav The next soundclip is 50% the speed of normalcy. I suppose it would help to isolate the sounds of the engine. http://www.ejzcars.com/350sound.wav The car is starting to blow oil smoke embarrassingly heavy right now. Just happened as of today. Any speeds below 2K rpm cause it to smoke excessively. At an extended idle, upon taking off, the vehicle behind me is engulfed in the blueish, foul smelling haze. At the very least, on the optimistic side, I don't have any tailgaters anymore. However, there are no noises from the engine. Except excessive injector knock from cylinder #1. It looks like <100 miles per qt. if this keeps up. Should I be concerned? ![]() ![]()
