Water in the oil

THEFERMANATOR · #1 01-06-2008, 09:25 PM

I'm not familiar with the VOLVO T-stat housing set-up. Maybe you could post a picture of it for us. I know on the MERCRUISER's many have some sort of check valve set-up that can cause problems. Or you could be putting the T-stat in the wrong spot. I know the T-stat in all of MERCRUISERS doesn't go in the intake itself, it goes inside of the housing and has a spacer under it. The 2 holes you are talking about were used on the 87-95 V8 truck engines for the heat riser ports for the heater core. Small blocks are known to get hot spots in the rear from no water circulating up through the rear of the intake, so GM put the steam riser set-up in to eliminate hot spots in the trucks. Gaskets are available that don't use those holes. What does the water look like in the oil? Is it a slimy film, or actaul water?

Slimy is normally condensation build-up from lack of heat. Really need to make sure you T-stat is set-up right. I have a MERCUISER housing I'll give you for the cost of shipping if you need one.

Will that fit mine? I'm interested.

The MERCRUISER housing I have is a 4 hose style as well. I know it's good. The reason I changed it out was it is a BRAVO style housing, and the engine went back into an ALPHA outdrive boat. It didn't restrict the water flow enough at slow speeds with the small outdrive water pump. I believe your VOLVO uses an engine driven raw water pump which is what this housing was for.

Here's a link to a picture of the style I have.

Yea yours is the same as mine but I don't think mine is bad, I was refering to the intake manifold on mine might be bad. I have a friend looking at my manifold tonight at work with a boroscope.
I have the same exact problem with mine during the winter, I don't get enought heat in the motor. My temp gauge never reaches 100dgs when the outside water temp id below 50dgs which is what I believe causes my excessive condensation.

Hey Garage, when I logged, we had one skidder that always ran cold and when I pulled the valve cover off to get to the injectors the whole top end had milky slime on everything. It all came from running too cold.

Spare you da man, you da man!!!!!

I think you found the problem with us talking , it sure des make since that without the thermastat attached inside the gasket the tehermastat would mov around in the housing and allow water to byp*** the thermastat. I'll be taking it out again this weekend or Monday so I'll post to let everyone know if this fixed my problem.

Thanks again. Therm I still want that housing because mine does have significient corrosion, so let me know.
thanks
garage
