Water in oil

I have a 93 Camry with a 5S-FE and I just pulled the engine to replace the rear main seal and a freeze plug that was leaking, as well as clean everything up. I didnt break into the engine, I only replaced the rear main and the freeze plug. I got it back in and it cranked right up and ran fairly smooth considering I hadnt set the timing yet. I took it for a test drive and after about 5-10 minutes it started missing somewhat so I drove back home, figuring I just needed to set the timing. Once there, I checked the fluids again and found much water in the fresh oil. I cant figure out what would cause this, since I didnt even crack into the engine and it wasnt doing this before. The only thing I can think of thatd do it would be if I mis-routed one of the hoses, which is possible. However, I changed the oil and switched the only two that I thought I couldve possibly mis-routed (2 of the 3 on the underside of the throttle body), and let it run for a few minutes and checked again and still had water in the oil. I have manuals but I cant find anything out of line on it the way theyre run now. But thats not to say theyre definitely routed correctly. I think its still possible that something is out of place, Im just having a hard time tracing it down. Nothings leaking underneath, and I did break off the top nipple of the Thermal Vacuum Valve and havent fixed it yet, so that vacuum hose is laying loose. But other than that, everything seems copacetic. Any ideas or advice would be much appreciated and I hope yall have a safe and Happy Holiday Season :)

how about trying a compression check. should tell you if it is a head gasket? mike

Ya, I was planning on doing that shortly too. However, just about a year ago I changed the head gasket and its been fine since then. Would it be possible that the weight of the engine/trans couldve stretched out the head bolts or something like that while lifting it out and putting it back in? Cuz both hangers are bolted directly to the head on each end, so all the time its on the hoist, all the weight of the whole drivetrain is held by the aluminum head. I left it all together when I pulled it too. I aint sure how much it weighs, but now Im starting to lean towards the head-to-block connection as maybe being the problem. When I changed the head gasket, I used head bolts I bought at Autozone where I got the gaskets, and Im sure theyre not the stoutest :eek:
