Toyota Repair: oil leak R22 engine, timing chain cover, timing chains

Question
I am working on an 86 truck, manual transmission.  The timing chain broke and I have replaced it, my problem comes from a massive oil leak, just under the head at the front of the timing chain cover at the very top.  I replaced the timing chain cover recently and the problem got worse, now the leak is antifreeze and oil( that chocolate milk looking mixture)from the same area at the top of the timing chain cover.

Answer
The gasket between the timing cover and the head is part of the headgasket, make sure this part of the gasket is still there and not damaged you may have to remove the cover again, I used to replace timing chains all the time without removing the head, if you're careful you won't break the gasket, I used lots of silicon RTV sealer before putting it back together.
