deMideon Posted April 16, 2006 Share Posted April 16, 2006 I am replacing the intake gaskets since I was getting some oil leaking out of the valley... I found a little water leak evidence (tan oil in the valley). One other thing that is really odd... I was using royal purple synthetic oil, when I pulled the valve covers I noticed the oil seemed really thick... it's only in about 2500 miles... in the valley it also seemed thick, drained it and yeah just doesn't seem right. It's also very black. I didn't think oil and water would really mix and I thought you would get some tan where the water was. Anyone have any ideas?

Synlubes Posted April 16, 2006 Share Posted April 16, 2006 Fuel dilution??? Does the oil smell of fuel? When oil and water mix it looks like milk, kind of tanish. What weight was the royal purple you started with? Quote Link to comment Share on other sites More sharing options...
deMideon Posted April 16, 2006 Author Share Posted April 16, 2006 Well I started with 20 / 50 I believe... I could believe fuel would get in it, but wouldn't fuel thin it down? And yes water and oil being milky is what I meant and don't have except a little in the valley Quote Link to comment Share on other sites More sharing options...

You're right about the oil and water emulsion... creamed coffee color. The black you found isn't too far from purple, and is the direction the color will shift eventually due to heat/contaminents. I'd guess it was mainly still purple, and just a trick of the lighting. (Unless this is a high mileage engine, in which case it may have been cleaning out old deposits created courtesy of PO). I notice that you are in Illinois. A 20 base weight oil will be thick there in the winter. I like 20-50 here in rainy CA, but it seems that your engine would become hard to crank in the cold. I remember using head bolt heaters to keep rigs warm enough to crank over, and in one really cold area, running one of the early synthetics (CONOCO Polar Start) where heaters weren't an option. Yes, fuel thins oil. / Quote Link to comment Share on other sites More sharing options...
deMideon Posted April 17, 2006 Author Share Posted April 17, 2006 Yeah.. so can't be fuel in it... it can't be water since it isn't tan... it's 70 degrees (well and the oiil is synthetic) so it's not that making it thick... Quote Link to comment Share on other sites More sharing options...
WickedWild Posted April 18, 2006 Share Posted April 18, 2006 I personaly think it's the 20w50 thats makeing it thick. Synthetic or not the watter and oil will separate. Is this a used engine (you did not build it)? Quote Link to comment Share on other sites More sharing options...
deMideon Posted April 18, 2006 Author Share Posted April 18, 2006 LOL... no I know what the 20w50 oil is supposed to look like, this is definately thicker that it normally is almost lumpy looking, but you can't feel any. The engine is very new about 4000 miles. This oil was in for about 2500. Quote Link to comment Share on other sites More sharing options...
