First off, when you replaced the head gasket, did you follow the correct tightening sequence and use a torque wrench? Did you check to see if you had stretch bolts......Use only once then toss and get new ones.
A cracked block just "does not happen" that easily.
And why not a cracked head? That is easier to crack.
Before you go into messing with chemicals, take the block into a machine shop and have them "magnaflux " the block and head. They will tell you whether it is cracked or not. If it is cracked - it is now a paperweight.
So, if the choice is between spending the money and taking to a machine shop for a crack check or maybe buying another head gasket and doing it according to the book.....only you know if you did it right the first time......the choice is yours. Personally, I would try the gasket route again with a repair manual along side to be sure I do it right.

Hello there, I am a toyota tech., for 18 years now. There are a couple of things that could cause this. I highly doubt there is anything wrong with the block. The most probable cause is the timing cover, Yes the timing cover. The timing chain goes from the crankshaft all the way up to the cam on top of the engine, and there are coolant passages right behind where the chain rides, as the chain wears and stretches the guides wear and sometimes break, there is one on each side of the timing cover.if they are gone then the chain just digs into the cover and will wear its way into the coolant passage, then it is a mess. You should be able to see down the front of the cover by taking the valve cover off, you will see the timing chain just follow it down and look carefully at both sides just below the head and see if the guides are there and in good shape. Have you ever had the chain replaced? It is possible that the head may be warped or cracked. If the cover is in good shape then you will probably need to pull the head and check it for straightness and cracks. You could get a coolant pressure tester and pressurize the cooling system and look for leaks also . Good Luck!

A slightly less expensive option might be to have the current engine's block and head remachined to specs, but cheap it isn't and you have to do both to get mating surfaces.
On another note, are you SURE you replaced the gasket correctly? Because it could've slipped just a bit in the process and caused an imperfect seal, either way if you take it apart again, that would be something to check.

Bad news - if you already replaced the gasket, you have a cracked head. There are no other points of contact for the coolant to interact with oil.
As for the effectiveness of the block sealers, I would certainly try that before junking the engine.

Did you have the head magnafluxed, any time you have a head off for a reason like that you should have it checked for crackes. Are you sure you torqued the head properly, in the correct order? If so you most likely have a major problem. Especialy if it had previously overheated. Engine block sealent is a temporary solution. you need to have a mechanic look at the car and advise you on what to do.

Cracked head, or busted head gasket. Either way the head has to come off...
