Oil Leak help
« on: February 05, 2018, 06:17:03 »
Hey guys.  I have found two small oil leaks on my car.  Could you all give me some guidance as to where these may be coming from?  See attached pics (sorry they are out of order.  The first and third pic are the same leak).  Thanks!

Let me try my amateur's guess, as an exercise:

1. Main shaft sealing cord (if the oil is brown, if red it is the gear box or hydraulic clutch leaking). Sealing cord on the back of the engine shaft is difficult to make it tight.
2. Oil filter connections (I think it is another leak). Maybe just not tightened properly.
3. Oil pan - usually wrong tightening (too strong) or the pan mating surface not straightemed. A bit wrong fiting anyway...

But please do not take it seriously, just my guesses, wait for someone knowledgeable to chime in.

Thank you Pawel.  I should point out that I am well aware of the transmission fluid leak shown in the first picture.  Unfortunately, fixing the tranny leak would likely require a full rebuild.

As clean as the car looks I would just monitor the leaks for now.  My car has a front crank seal leak that is covering the bottom of the engine with oil.  I think this year I have to finally address the leak.

Main shaft oil leaks turn a very clean engine (and undercarriage) into a grimy mess in very short time. If you drive your car frequently. Eventually, you can't tell where the leak(s) is coming from. That's my story anyway.

I had a small oil leak that I could not find, checked every place on the engine.  Later found that the manual steering box was the cause. Paul, '63 230SL

Thank you guys.  This engine has about 700 miles on a complete build.  Just got a 4 post lift so was able to get under the car.  The oil leaks are very small and slow.  Car totally dry today after cleaning them up last night.
