VAC water in oil

mmaki · Oct 24, 2016

Imagine my disappointment when I took the valve cover off today to investigate some noisy valves only to discover a thick white frothing lining the inside valve cover.

The manual says it is either cylinder sleeve packing or cracked block. Is there a easy way to determine where it is coming from? Pressurize the rad with air maybe?

I have compression, it doesn't seem to be burning water, there are no air bubbles in the rad that I can see.

Before haveing a corinary, you might consider condensation and how the tractor was used in the past couple of years. If it had been worked hard and run at operating temp. there shouldn't be much white slime on the top of the engine. If it just putted around, and run ocasionally there will be a lot of it.

It may be just condensation that collects on the valve cover as the cover cools the fastest and attracts moisture as the block cools. This is most prevalent when you do short runs and the block doesn't heat enough to drive out the moisture or the engine is running too cold like a defective T-stat. Let it set over night and crack the drain plug to check for coolant leak.

Hey Joe.
We're on the same page here.
How are you doing health wise?? I had a really lousy 2015, but this year has been much better for me.

Be careful about pressurizing the radiator. It's not a pressurized system. I don't think it will handle more than about 7 psi. See if there is any water in the bottom of the oil pan after the tractor sits for a few days. Don't panic yet, even if it is leaking some block sealer might fix it.

I have seen that many times over the years and many times it is a not a real problem with then it is not run long enough to burn off condensation.

I would loosen the oil pan drain plug just till you get a drip. If you have coolant in the oil and you have not run it for a few days you should get antifreeze when you loosen the drain plug. But if it is from condensation the the drip will be very likely to be oil. So if it is oil only then the problem you have is a thermostat that is missing or bad or you do not run it long enough to get it up to heat like it need to have done

Been there,, done that! Rebuilt an Oliver 550 and just ran it for short drives and never really worked for any length of time. Went to check the valve clearance and found the entire valve train was covered with what looked like Vaseline. No problem after I ran it long enough to warm it up to operating temp for 30 min. or so.

Hi Loren, thanks for asking. I followed your 2015 difficulties. Pretty much the same thing I went through about 5 years ago. I've had 3 ablations for A-fib, last one in April. Doing much better after that one. Quip smoking 4 years ago but I am 73 next week and I haven't and don't intend to give up anything else.
