there are two possibilities here;

1: bad head gasket

2: bad intake gasket

start by running a compression check, dry and wet, and post the numbers. if your compression numbers are ok, then pull the intake and replace the gaskets. i had one leak once, and you could fill the radiator until the motor was full of coolant before you would see water leaking out.

i agree with rbohm, sounds like a gasket. oil on top of the timing cover was probably from oil leak in the front of intake. the cork gaskets blow out ,i dont use them. just build up a bead of silicone in the front and back and leave the cork gasket out of the intake. the timing cover is probably leaking into the block. did you use sealer on the gasket on both sides? make sure all the bolts are in place and tight some of them go into water passages. the gasket may have sliped when you changed the timing cover
i would be willing to bet the timing cover gasket is the culprit. you will need to change your oil after you find the leak

rbohm and horse sence thanks for the reply........i will do a compression test as soon as i buy a tester
did use sealent on gasket on both sides.....but i put the timing cover gasket on the block with sealer
pressed it on lined up the bolt holes..but didnt put the timing cover on till about 2 days later putting more sealent on the back of timing cover.then bolting it down.i think i might have screwed up by not doing it all at once..i drained the oil looks like milk chocolate

yeah thats your problem, its the timing cover. the cover has to be bolted in place while the sealer is wet .the sealer acts as a glue and seals every thing water tight

When you reinstall it, make sure to torque the bolts down properly and in the proper order as well.

It's not a bad idea to put a bit of RTV silicone gasket sealer on the threads of the timing cover bolts and long water pump bolts that go through the cover on either sides of the coolant ports. Always use black or grey RTV, as the blue sucks!
