Classic/Antique Car Repair/1978 450slc mercedez, sprung oil leak


drove car today, started car left a trail of oil from garage down the street. smoke when oil hit exhause, turned around made another trail of oil home.. shut engine checked oil, low. no leaks on top and sides of engine leak somewhere behind engine and under.. what u think?  thanks ray

Hi Ray:
If the leak is from the bottom, a few things
could be the cause...

1. Check around your oil filter. Make it has not come loose.
2. Check your oil pan for leaks or loose bolts or bad gasket.
3. Check your engine front seal for oil leaks.

My guess is that one of these areas has a problem. With oil
pouring out like that and no previous leak problems, make me
think the oil filter or pan cover is loose.

I can answer most questions about autos built in the 1920 through 1990. Mechanical issues and technical questions are my expertise. I also have a general knowledge of most older automobiles. Keep in mind, I can only provide answers if the questions are very specific and complete. Without details, I can only speculate and that's not good for solving your problem.


I have owned and maintained Silver Shadows for over 10 years now. I find most mechanics and even Rolls Royce mechanics have very little knowledge about these automobiles. I have researched these cars in quite a bit of detail and can pretty much tell you what is wrong, if you can describe the behavior in detail. I have saved quite a few RR owners a lot of money and aggravation due to improper diagnosis. I am the owner of Classy Transportation, LLC a luxury limousine service specializing in antique cars, classic cars, vintage cars and exotic cars.
