400 oil leak
Dorien
Those heads can be so porous that if the water jacket is pressurized,
bubbles will appear on surfaces that look good. In particular around
number one cylinder behind the water pump. If you take the head off, a
local engine shop will be able to help.
If oil appears to be leaking from the Distributor shaft area, it is
usually from the join in the rocker cover behind it and some care plus
a decent gasket cement (Loctite Grey 5699) will seal it.
If your going to get pistons out I'd remove the engine completely
because they need to come out and go back from the bottom, although I
think you can push them far enough up to get the gudgeon pin out. It
is all a fiddle.
I'm doing a 4.5 L Bentley engine now for relaxation! The biggest
problem is weight and I'm getting old.
