most cracked blocks you cannot see the crack with your eye. the bottom line is you need a motor replacement. Roy

It's common on these engines to develop hairline cracks at the camshaft journals. When the engine / cyl. head warms up the crack(s) will open allowing engine oil mix with coolant. You can fix this problem by replacing the cylinder head assembly. There is a TSB describing this problem. If you post an e-mail I'll look for it and send it to you. Zee

have you checked your oil cooler in the radiator? It can cause the same problem
