So I got a 91' Ranger with the 4ald and a 4.0 ohv from a family friend, it started leaking coolant from between head anfd the block. To try and gimp the truck home the auto part store told him to use Aluma Seal and everything was good then then all the sudden the oil light came on and the truck puked oil all over the exhaust manifold. The truck never over heated at all but it was clearly leaking coolant from between the head and block. Is this a blown headgasket or something else? my experience says blown headgasket but the puking oil is mystery to me as I am completely new to the to the 4.0 OHV. No coolant in oil and oil in the coolant. He had the truck towed home and then he bought a new rig. truck is emacculant and well worht fixing in my opinion, transmission has less than 12k miles, body is gorgeous, paint is darn near flawless maybe 2 years old.
 
head gasket::::
water leaking into cylinder, water being pressurized by piston, pumped into oil port, filling oil pan with water. it didn't run long enough to turn oil white. engines don't make oil...
you need to pull it down. straight edge the heads and block. boil out the block. do any repairs to the block and heads as needed, possible milling.
put her back together. new bearings, rings, ect. lifters can be bled, cleaned and pumped with new oil, until clean oil comes out. (atf works good at cleaning the lifters). if you want to run e-85 only or av fuel, install high compression pistons, with beefier rods and crank. go to 11-12:1 compression. arp head bolts...
 
Definitely sounds like a head gasket to me. Hopefully the heads didn't crack too.

One way to find out...Sounds like you need to change those head gaskets!

Hope it all works out for you and all you have to do is those gaskets and a bit of flushing.
