Oily Engine - possible causes? (photos included)
Posted: Mon Mar 30, 2015 4:32 pm
I was mucking around removing the glow plugs today (occasional lumpy starting and whispy smoke for the 1st half mile) and I think I found my main oil leak (it'a always mentioned on my MOTs as an advisory).
Here is the oily area of the block (not the head at all) - driver side - goes all the way down. Is fairly local - underneath - to the 1st (front) cylinder.

Now here is a pic of where it seems to be coming from: An inlet manifold bolt area..

You can see how it seems to be eminating from the bolt area and trickling down.
Finally, here is a pic of the manifold from above (that's not the same bolt - its the top one of the same cylinder)

As you can see it's a bit oily, but then so is the one on the other end, but no leak underneath.
Inlet gasket? (btw - it's a slow leak - I change the oil once a year and its never low)
