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.

When I had to replace the original block in our halftrack because of a failed attempt to fix an external crack, finding a good replacement block was tough. The first replacement block was an old stock / rebuilt and pickled many years ago. It was covered in a black tar like coating, block cylinders were resleeved and new valve guides and seats installed before being pickled. When I had that one pressure checked it had at least 5-6 internal cracks and was uneconomical to repair. The second replacement block had one crack from a cylinder wall to a valve seat when it was pressure checked. This one was repaired by welding / machining the crack and resleeving the cylinder. So I have had my share of cracked halftrack blocks, but after all they are 70yrs old with many years of abuse.

Ok, I dumped two 16 oz "head gasket stop leak" I picked up from the local auto parts store. Because of the larger cooling capacity it took two. It seems to have sealed the leak. I let it set for almost 48 hrs with the oil plug out, and no drippy.... I put new oil in it, and been running it for over a hour now, and water level has not gone down. I will find out in a couple of days after it sits if it is getting any water in the oil again. The bad news, I think I ran it for a little while with water in the oil, and did some damage to my rod bearings. I can tell the bottom end is a little loose. No way of knowing because It could of been that way when I drug it out of the farmers field. I'm contemplating just trying to throw some new rod bearings in it, with a new oil pan gasket for now, and see what it sounds like, and what the oil pressure is. Oil pressure is only about 30-35 when at 2000 rmp. seems low to me. Idles around 15-20.... When I took the head of it did have a pretty pronounced ridge on the cylinders, so it does have a few miles on the engine. a little blow by also. but, hey, at least it runs, and I can drive it around low speeds for short distances. perfect for parade speeds.......

John,
I sell new oil pan and side cover gaskets $60 a set. Let me know if you need one.

Being a mechanic I too didn't like cheap fixes, but, cheap customers mean cheap fixes. I actually called rislone a few times with questions, and was very satisfied with answers, so telling the customer i give no warrentees we proceeded. It worked, and going on 2 years. Since then I have used it in my own cars and other customers. You cant expect it to work and a severe leak.
As for damage to bearings, Ive seen water in the oil many times, and customers that just wanted oil change not the 800 dollar head gasket change. I have never seen any damage from water in the oil, unless it has been sitting for a time, then rust starts. Of course if there is a ton of water than that's different. If you have just whiteish froth in oil, just do a few oils changes in short successions.

If you have the pan off you might want to check the bearing clearances with some plastic gauge. It should tell you if the bearings are loose and then you can decide how to proceed. I think the mains should be ok. But if you do have problems it will most likely be the rod bearings.

Now that I think about it. When my head gasket blew and I changed fluids I had a lot of coolant in the oil for some time I'm guessing. Even though I changed the fluids I developed a low end rod knock. That is why I'm pulling my engine.

Thanks for the replies. I probably will end up replacing at least the rod bearing and gaskets. This will probably solve the rumble it makes at an idle. Still no water in oil after stop leak.
