Ford 7000 porous or not

[daveydiesel1]

Our 7000 is puttin oil into water and water into oil, the radiator is of her and theres 2 water pipes on it and 2 oil pipes from engine goin into it, would it be common for them to mix fluids in rad if a hole appears or is it most likely engine gone pourous as i havnt got rad away to get checked out yet and just was wonderin about it tonight

Is it original block or a replacement one with x s on side of it?
Has it had antifreeze.

IMHO, it's unlikely to be the radiator. It's not bound to be porous either -It could be the head gasket.

Our 7610 did the oil in water thing many years ago at around 4000 hrs. Set of liners cured it and did another 9000hrs on the original engine with no more issue before it left us.

You could plug the water in and outlets of the radiator,fill it and see if water runs out of the oil fittings. Would be better lightly pressurised with a proper pressure tester but an airline at reduced pressure would do the same job if you can make up an adapter for the filler neck.(An old cap with a tubeless valve fitted into it).
If nothing leaking there,put the radiator back in,fill and pressurise and see if water runs out of the sump drain hole. Better with the sump off though.

I have had similar rads on an old Sanderson that have leaked across the inbuilt cooler. (in this case it was transmission fluid).
What would happen if you could bridge the oil cooling pipes then refill the rad with clean water. Run to reasonable temperature and see if there is any coolant loss from the cooler ports?

It is original block. Gonna get it re cored coz doin her up but was just wonderin if any1 had this prob b4

I once put a short block in a 4600, only to eventually discover it was just a core plug in the head that had gone porous.
Dont assume anything.

 

[7610 super q]

Fairly obvious when mine went porous (4610 ), take out sump plug, and gallons of water poured out. As said, investigate other options first. Couple of bottles of head gasket sealant cured mine for £80, if you want to try that first, otherwise a block from Timik, or MJ Robinson have a selection of engines.

Rad back in, join oil pipes to test

 

[daveydiesel1]

Think al see what rad specialist says coz it has to be recored before restorin her. If it comes back that it was ok where is the next place to look. Dont want to change the block coz it would devalue her

Just put a small amount of pressure in to the rad
connect the two oil pipes together so that bypasses the rad is the first thing to do
If it is leaking remove the rocker cover and look at the cor plugs under the rocker shaft and check if you can see any water do that first
There have been a lot of engines blocks done and the water is still leaking
