Title: Little water in oil
Post by: 69kona on March 29, 2016, 06:06:32 PM: I took my boat out this weekend and the river water is cold so I turned my water down a little and the water temp never got above 140 . I usually run it at 160 to 180 .. And oil temp was 170 ... Would this contribute to water in oil ? I did a pressure check and it held pressure for hours ... So? Am I over looking something?

2 dumplines
Water comes in on headers at 2200 rpms

I wouldn't say milky but alotttt of froth in the valve covers and dipstick. Engines draw a lot of moisture in when they cool down

I've seen numbers like yours with an oil cooler that had an internal leak is all.

How is your water routed?

What fuel are you running?
How hard and long did you run it?
Has it run before?

Doing a pressure test like I did would rule out a leaky head gasket or intake gasket right?

Depending on how much water pressure your getting in your motor. It can still seep through. It doesn't take a lot of water to make it milky

Post by: GT Jets on March 30, 2016, 08:58:00 AM: I would say she needs to idle at about 150°F. You could be over over dumping,but the system sounds close. By closing the water down more will raise the header cut in point. Have you pulled the check tee apart and made sure it was clean and in tact?
Was there water coming out of the weepers?

With two dump lines, you may be able the valve one (hate doing that) so you can raise the temp and keep the headers working right.

The oil never got warm enough to steam out the condensation.

How much oil? What pan?

I like to ensure the oil stays in the 220-250°F range. Yours was way too cool IMHO.

Nice thanks for responding Gt I appreciate it! I have not check tee yet . I will do that next .
I am getting water out the weep holes
10 quart oil pan and I run nine quarts of oil
How do I get oil temp up?

Easiest way is more water temp, three ways to do it, reduce the amount of water flow through the engine (simple reversible valve throttling), run a water to water heat exchanger on the dump line to preheat the cooling water, run an oil cooler (I know) on the dump line with warmer water.

Also you can lean the fuel ratio if she is running a little fat.

I think I found the problem .... The weep holes were plugged in the headers ! GT
What do u think ? Would that do it ?

Sure a possibility.

I personally would start there. Also pull the tee apart and ensure all is good in there. It don't take much to give the oil a barfy hue.
