water in oil
Hi all this is the first time posting here. I have a 04 with the 4.7 h.o. engine. It stated over heating last year so its been sitting. So far I put a new radiator in it a thermostat. Still had issues. At first I didn't have water in the oil. Then it started blowing out white smoke checked the oil now there is water in the oil. My first thought was head gaskets. So I checked the compression. It was 120 to 136 psi across all 8 cylinders so I don't see how it could be that. So I was wondering if it could be coming in through the timing chain cover. Has anybody else had this problem before. Any help would be appreciated. Especially before I start tearing it apart.
I bet you find that it's a cracked head and not a blown headgasket.

As a last resort, try some of that mechanic-in-a-bottle coolant leak/head gasket seal stuff. It can work. I've had success with Rislone Liquid Copper Block Seal but there are other good products on the market too. It may even take two bottles. You could end up with some side effects like a partially clogged heater core but hey … if it works, you can eventually drain it out with the coolant and refill. The fix is supposed to be essentially permanent (if it works).
