oil in radiator res

Statistically your 2KS is going to have the head off soon.

 

Let us know whatcha find out!

 

my guess would be a cracked head, cracked liner, or maybe the liner has slipped. my advice to you would b quit fooling around, take it to a shop before you lose the whole engine. lots of luck

 

After thinking some more,,,ya said that after it sat over night it still had pressure in the cooling system yes?
This would be the compressor bleeing air from the tanks thru it,,,into the cooling system.

Another question would be...is there any coolant in the oil? If so,,,then that would be because there's a crack in a liner, leak in a head gasket/head letting coolant leak into the oil-pan AFTER the engine is shut off over night. If ya have oil in the coolant & coolant in the oil it's a liner, head, gasket, etc.
Is there any sign of coolant in the oil?

 

i did not understand everything i thought he had coolant in the oil also

 

He never said anything about coolant in the oil unless I missed it.
My comment about that was a question only.

 

id bet its a head gasket. but as for the oil in rad. once you get it fixed. drain all water out. refill and add powder dish washing detregent drive it around a few miles after warm up than drain and flush a few times....works great gets all the oils out plus breaks up all that buildup in the system
