you might have a cracked head. i would do a compression test. where the numbers start to change, thats where the crack may be. and you should also try getting the head pressure tested.

Antifreeze in the oil is never good and only means one of 2 things. Like jdm_master said it could be a cracked head. I think if the head gasket goes it will leak coolent into the oil as well. Either way the motor is on the fast lane to death.

You guy's are all WRONG!!!!. This is a very typical problem associated with the timing chain assembly and front cover. This problem was first noticed with the NAPSZ engines of the 80's which use very similar components as the KA24e. When the engine becomes excessive in high mileage over 100,000miles, the timing chain as well as the guides become weak and old. Once the chain is given too much slack. The chain then begins to grind into the front cover where the location of the coolant pump assembly is found. At any given point once the front cover has been grinded into too much, coolant from the coolant passage begins to leak into the oil pan. This is a problem that should be corrected IMMEDIATELY as it will cause hydrostatic locking withing the cylinder and can bend a rod and destroy the valve train....

and you don't have to SAY IT LIKE THAT!!!. we are not wrong completely because what if that is not the case for him?? how about you wait and see what the outcome of his problem is before you blatantly say YOU ARE ALL WRONG!!!!. you prove a good point, but gee grow up.

Thanks that is what I was going to check next when I got the head off I noticed that the right side guide was totally gone so the chain was riding on the timing cover. the motor has 190,000 on it

well at least you arent retarded. a friend of mine had his friend call me cause she had a problem with her car. she said "i needed antifreeze, but i think i put it in the wrong place" so naturally i asked her where she put it and she said "uhm...there is a cap on the top of the motor, i opened it and put the antifreeze there. and when i started the car it went bang" i simply shook my head and handed the phone back to my friend.

i should have said "HERES YOUR SIGN"

That is classic reason why clue-less chicks should not be allowed near anything expensive.

We can wager a bet through paypal if you like I have $50 dollars that it is the timing chain and assembly. I've worked on plenty of high mileage KA's and NAPSZ motors to know obvious problems. Fact is the timing chain assembly will go before the head gasket leaks. Compression starts to go down the crapper if it was the headgasket as well, you would notice the power loss before the leaking, if it were the head gasket.Plus if the leaking was coming from the head you would start to hear rod knock......

No that isn't. You agree with others that the problem is coming from the head, or gaskets. I claim that this is a timing chain issue.
