Engine made a milkshake - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Well I must have gotten some antifreeze into the oil cause I checked the oil and there it was milkshake. Engine prolly ran for 2-3 mins tops. I did do a intake swap so thats most likely how the water got in there. I drained it all, pulled the filter and let it drip for about 15 mins. I dont have another filter to use so what I did was run 4 quarts of oil through it until it clean oil came out. Anything else I need to do? Hope I didnt mess this engine up.

Most likely no damage. Start it let it run long enough to really get the water out of the oil...as long as it is not getting more from an intake leak into the oil galley. The elmulsion does have some lubricating qualities but not as much oil film strength like clean oil. Start it...watch the pressure and then check it again after about 5 minutes or so. If good run for much longer to get the remaining moisture out of it.

Had the same thing happen on a SB327. Boy when the repairs were done and some 2min cleaner run through the oil on the dipstick sure was clean.

Will do guys. Thanks for the info.

I put some oil in it along with a new filter, ran it for 2-3 mins and then drained it again. Filled it back up and new filter let it run for about 10 mins and now I am about to go out and see what the dipstick says. I got one more filter and enough oil for one more fillup. Let hope that 2 times is enough.

Ok I just drained it and there was a little water that came out with a hint of white. After about 2 seconds it went to straight oil. Looking good so far..

Well it came out ok. I changed the oil again and it had a little bit of water in it other than that its oil. Im going to put about 50 miles on it and change it again so that should get every single drop out of it. Lesson learned. Dont forget to change the oil after a intake manifold swap.

Had that happen on an intake swap before. I very quickly went from a 5qt oil pan to about a 10qt pan. My gasket didn't seal and filled the block up with water. We quickly noticed that something didn't sound right and shut it off before any damage occurred.
I fixed the gasket and ran clean oil back through the motor for about 5 minutes. Another oil change and 2 breathers for 100 miles and everything came out fine.

I think you'll be fine.
