Oil in water

Post by willik43 » Tue Oct 31, 2017 2:54 am

Hi all,
a friend of mine came to my workshop with a problem. He has Oil in water. Radiator inside is very greasy but there is no water in oil, no one drop, no foam or something like that. (If it is vice-versa - water in oil - it is relatively common failure.) It seams to me quite strange failure in desing like L134 engine has.
Have you seen it?
Thank you for ideas.
Petr

Head gasket.
Just starting to let go.
The high pressure in the cylinder is leaking into the coolant but the leak is not bad enough for the low water pressure to leak back. Yet !
You might try retorquing the head. See if it tightens up some.
If it does, flush the cooling system and see what happens.
If not, time for a head gasket and check the head surface for flatness.
