Water in Oil
« on: March 06, 2015, 11:23:31 AM »
Wondering if anyone has ran into getting water from radiator into the oil... I recently replace the head gasket with a new one, thought maybe this was causing it. but not sure... wondering if anyoe knows possible problems with white engines that cause water to get into the oil.. thanks, john

Did your engine overheat? If it did just replacing head gasket might not fix, need head machined. Usually only 2 reasons for that, head gasket or crack in block

My engine did not and is not overheating... but I have only drove it 5 miles at a time, which should be enough for it to overheat.  I guess I will replace the head gasket again.  maybe I put it on upside down?  Any good places to get a head gasket?

Did you replace fluids after changing the head gasket? If not you could have gotten some contamination from that. If not you have a crack in the head or block some where. I had this happen with an old Chevy six engine a while back.

Yes, I changed the oil after the head gasket was replaced. it is definitley still leaking water into the oil after the new head gasket was installed.  I think I will pull it apart again, and install a new head gasket after I have the head resurfaced.  I got my gasket from Gary.  any other places to get a good head gasket?

did you re torque bolts after a normal engine temp run? If you wanna try, run Rislone Head Gasket Fix, HD (more pricier) one. Ive had great luck with it in vehicles

I was thinking of trying to use a head gasket sealant you put in the cooling system... I just ordered a new gasket. I think I will try and replace it again, this time take the head to a machine shop and have it milled.  if that doesn't work, maybe pull apart th oil cooler and check it for leaks...

when you take it off, you should see discoloration on it from where it was leaking if it is the gasket leaking

Did you spray the gasket with copper coat? I hear that is what you are supposed to do. That is what I did. Also, you will want to re torque your head bolts two to three times after initial run in.

I did use a spray copper coat sealant on the gasket... and I did retorque a couple times.  I thought I did everything right, except for taking it to have it resurfaced... this time I will do that...

I would pressure up the coolant system and drop the oil pan a check for any signs of it dripping down from inside the block. They make kits that hook up to the radiator, and you pump it up like a small bicycle pump and has a gauge to keep it from over pressuring it up. Or can rig up a fitting and use a air compressor and regulator.  I would check the oil cooler as already mentioned. Have you noticed if any of the cylinders have coolant in them or the spark-plugs fouled out.

Spark plugs are not fouling.... even after it sets for a few days it starts right up... good idea to drop oil pan... I think I will see if I can't find a good take out oil cooler and replace it, and check mine when I take it out to see if I can get it to leak..  Just makes sense its the head gasket, as I just took it off and replaced it.. but it was sitting for years, so maybe it already had this problem, but didn't notice it until after I replaced the head.. thanks for all the advice.

When we did the head on mine we had to go back and retorque a couple of times.

 Forgot to add since its a flathead engine, pull the side doors and see if the coolant is running down from where the valves are back into the block

i would suspect its a cracked head or block.
i had one do the same thing.
there is one other possibility that hasn't been mentioned. a leaking oil cooler. (whoops, i guess it was mentioned)
i have never heard of someone with this problem but anything is possible.
