early on I was concerned (a little) that my oil cooler might have a tiny leak. When I first installed the engine I saw about a few big drops of clean oil in the coolant recovery tank. just a few drops. havnt seen any since. I wondered that since the oil
pressure is about 50-60 for a few minuites during warm-up (goes down in about 5-min or so) that if the cooler had a tiny leak it could be squeezing some oil through the leak into the cooling water.
Fast forward-
Had some freezing weather- drained cooling system- a few days later I put in 2 gallons of antifreeze and balance water.
It looked like it vapour locked- like not enough went in. I watched the level for a few days didn't go down until I ran it.
Got some more in and the no more would go. Yesterday I checked it and the overflow tank was empty. It seemed to tale
a good bit ( a gallon or 2)
I was thinking that if I had a oil cooler leak- that the water might gravity drain down into the oil.
Checked the oil color- nice and clear. Ran motor and drove it around the yard for about 5 min to stir things up.
Oil looked the same- nice and clean and clear- did NOT look like coffee with cream in it or frothy white.
I figured that if water HAD drained into pan while sitting - it might just sit down there and be separate until the motor was run.
Didn't see any change on the dip stick as far as the oils color ..... however I also figured if I DID have water down there-
the extra water should raise the level of the oil floating on top of it and show over full on dip stick.
When I look at dip stick there is oil all up it- but it looks like I have not got the engine hot enough to heat soak the
plastic tube the dipstick is in- to get the excess to run back down into pan.
So I really cant tell for sure the oil level.
I could drain the oil into a new 5 gallon bucket and look at it- see if I see water- and see what the total volume
looks like ....... Let it sit overnight and check next day for visible water.....
Do I need to do that ???????? It is brand new oil- can pour it back in if it looks good......
I may replace the cooler later just as a preventative. but id rather not do it just yet-
Not sure - should I run it for longer and get it fully hot and then check the oil again the next day ?
