Re: '84 454, oil in coolant????

Yep born and raised here. The bit of oil I saw in the top of the rad was very odd, that's what really got me worrying. My Dad and I looked at it after work today, compression tested from 145 to 155 except for #2, went to 120 and started bleeding down slowly. #2 plug was wet, #4 plug was as well but not as much as #2. Really strange as I didn't notice any smoke from the engine when it was running either. Oil looks like it's leaking from the front of the passenger side head/block area also. When I get time I'm going to pull the intake and heads and get them checked out, hoping I'll find a messed up gasket under there.
