We have a '93 300TE 4Matic with 270,000 miles. This is a 103 engine. The engine has minor oil "seeps", our very good "indie" has used a flourescent dye in the oil to locate all the areas. I use about a quart of oil every 5000 miles, I use Castrol 10W50 and change every 5M miles. The seals were done at about 150M, engine runs fine, the problem is the drip wherever I stop the car. We can't find another car we would rather have so the problem is whether to have the gaskets replaced, along with other work while they are in the job. After reading the various gasket comments I get the feeling maybe we should leave this alone and tolerate the drips until it gets much worse. Taking the head off might be opening a can of worms. I'd like to hear any comments. We have replaced the waterpump and alternator, the powersteering pump has a minor leak. Thanks for your comments. srharvey
