Hey folks im stumped again. Ok so I have a new rebuilt head from LC Engineering, I did the dual row timing chain with steel back guides upgrade, new timing chain cover, all new seals and gaskets, new LCE oil pump, water pump, ect, ect, I did a pressure test on the coolant system at 10 lbs of pressure for well over a hour and it held steady. The kicker is I keep getting water in the oil. Every time I change the oil I run the engine for about 30 seconds, check oil again and its cloudy, Drain and keep finding water/coolant the oil is a white brown color. So now im kinda stumped any ideas?

I wonder if your old guides worn a groove on the the timing cover causing it to leak.

I said above I put a new timing chain cover on already,

My bad, glanced right over that.

How much water/coolant are you seeing?

Has the engine been ran to full operating temperature and driven around for longer than 5 miles?

For me sometimes it has taken a couple oil changes to get all the milkshake out of the engine. I usually run some engine flush stuff through it to breakup the mess and I use a fairly cheap oil filter on the first oil change.

Has this engine been machined by you or the PO? If so the New timing cover might be too tall, allowing a small gap between an oil passage and a coolant passage. I hope this isn't the case

The block is stock nothing has been done to it. The head was a used piece COMPLETELY rebuilt for me from LCE. I installed a new head gasket and head bolts.

Was the head shaved?

I'm not sure on that one. But I'll find out in the morning

It's a tough thing to find out if you don't have paperwork from the shop that decked it. If it was shaved right, only about .010" was removed. Whenever you put a new timing cover on an old block, you should have the machine shop check the deck with the cover bolted on. Otherwise the head is lifted a tiny bit by the taller cover and can't seal correctly.
